1 Pig only "lives" into the high -rise building

Breeding is more efficient and environmentally friendly

High -rise pigs have not only improved pig farming efficiency, but also an environmental protection revolution.

The reporter saw in the Green Lake Farm that it was built and built here to build a number of five -story high -rise buildings. They are not industrial plants, but new pigs.

Huang Zukang, general manager of Green Lake Farm, said that the company has gradually formed the concept of low -carbon, environmental protection, modules, and efficient pig farms design and construction. High -level pig houses and obtained 7 national practical new patents.

It is understood that Green Lake Farm settled in Zhaiwu Town in 2003. "Our company has developed step by step to today's scale. While expanding the scale, our company focuses on the investment in ecological and environmentally friendly breeding technology. 240,000 square meters of high -level pig houses, and built into the use of more than 10,000 sows and supporting commercial meat pig production lines in the use of depository. "Huang Zukang said.

The reporter saw in the Green Lake Farm that the new environmentally friendly high -rise pig house resembles a cube with five layers. "High -rise pigs, each floor of pig houses is not a simple stack of ordinary bungalowed pig houses, but the overall design of the overall design from the perspective of ring protection and the growing comfort of the pigs." Centralized sewage, layered ventilation, and high -altitude exhaust gas design, so that each layer of pig houses are relatively independent and internal, so as to achieve efficient cultivation and facilitate stratified epidemic prevention; No matter which floor is on, there is a uniform and comfortable growth environment; in order to overcome the problem of high -rise feed transportation, the multi -layer storage and transportation system is developed on the basis of the original bungalow pig house feed transportation, so that each column of pigs only have enough enough to have enough. Feed feeding.

"Each layer of pigs can breed 1500-1700 pigs, depending on the adjustment of the conditions. And the feeding, feces collection and ground cleaning of each layer of pig houses are automated, which greatly improves the farming efficiency. We are on each layer. Equipped with a comfortable room, hire a couple to settle in, and do a good job of inspection and inspection. "Huang Zukang said.

According to reports, although the model of Green Lake Farm has invested huge in the early stage and a large extension of supporting facilities, based on the combination of advanced floors design with high -tech hardware, it can efficiently, continuously intensify the use of land, and realize the scale, efficiency and industry of pig farming, efficiency, and industry. change.

In addition, in Yangmian Mountain, which is 10 minutes away from Green Lake Farm, the company has invested in the construction of a affiliated company -Heshan Green Lake Yangmian Shan Agricultural Development Co., Ltd. (hereinafter referred to as Yangmian Mountain), covering an area of ​​about 133.33 Hectare (2000 acres), currently two 9 -storey new environmental protection high -rise pig houses have been built. The construction area is nearly 50,000 square meters, with a total of 50,000 pigs. It is reported that Yangmianshan Company plans to build five 9 -storey high -rise environmental protection high -rise pig houses and related environmental protection facilities before 2024, and build a large -scale production link for sow -producing noodles and pigs. At that time, the annual outlet will be expanded to 90,000 pigs, with an annual output value of about 400 million yuan.

"The new environmentally friendly high -rise pig house is fully closed. The air entering must be filtered through three layers of filtration, and the exhaust gas must be filtered by three layers, which is conducive to efficient breeding and layered epidemic prevention. Therefore, our company not only has not been affected by African swine fever, but also The amount of childbirth has been increased and the growth cycle of pigs is shortened. "Huang Zukang said.

2 The use of manure resources

Realize the cultivation of the ecological cycle

High -rise pigs are a wonderful epitome of the standardized scale breeding of Heshan City. In the Green Lake Farm, in addition to the modern high -rise pig house, there are more than ten ponds in large and small, with fruit trees and gardens around the ponds. When you come to the Green Lake Farm, the environment of the mountains and rivers is comfortable, making people mistakenly think that this is a beautiful tourist attraction. With such a huge scale of production, how can the green lake farm avoid breeding pollution? "Our company has always attached great importance to green production, adhered to the ecological circulating breeding model, and built a three -dimensional circulating agricultural ecosystem of" agriculture, forestry, animal husbandry and sideline fish+biogas power generation "." Feng Xu, deputy general manager of Green Lake Farm, said that in 2006, the company built it The biogas tank and harmless treatment of the wastewater finally meet the irrigation standards. It is used in the surrounding economic forests, which basically achieves the "zero emissions" goal.

Since 2019, Heshan City has officially launched the use of livestock and poultry manure resources to use the county to promote project work, with a cumulative investment of more than 70 million yuan, and promoted the implementation of feces resources in 56 livestock and poultry breeding projects in the city. As a leading enterprise, the Green Lake Farm, this year has taken a milestone step in the process of promoting the use of livestock and poultry manure resources. The project also obtained 10 million yuan in support for higher -level policies.

Near the new environmental protection high -rise pigs of the Green Lake Farm, the huge black film biogas gas pools are particularly noticeable. Lu Liming, general manager of Heshan Green Lake Biological Energy Co., Ltd. told reporters that the use of organic waste resource -based equipment was installed in these buildings in front of the biogas. Power generation. At present, about 300 tons of feces are treated daily, and the power emitted by the biogas pool is acquired by the Southern Power Grid. After full load operation, the annual power generation is about 5.28 million kilowatt -hours.

"We cooperate with the Chinese Academy of Sciences to implement the technical use of the most cutting -edge manure resources." Lu Liming introduced that the feces resource utilization project is to treat pigs excrement through mechanical scraping and solid fluid separators. Organic fertilizer, as a greening fertilizer for the field, separated sewage into other follow -up depth treatment such as anaerobic fermentation. "Through the implementation of feces resource utilization projects, the solid feces after solid fluid is separated by micro -division hydrolysis technology to make the hydrolysis rate of more than 60%, reduce the amount of sludge in the later stage, and the liquid manure is made of high -efficiency anaerobic technology system. Marsh, the volume gas production rate is 4-6nm³/d/m³, and the COD degradation rate of 24 hours is 90%. "He said.

According to Lu Liming, Green Lake Farm is one of the largest -scale pig farming bases in the province and even the country, and has the basic conditions for implementing the use of manure resource utilization projects. "Through the implementation of feces resource utilization projects, biogas, biomass carbon and biogas organic fertilizer are used to use pig manure. Biogas is used for combined heat and electricity, biomass carbon is used for soil improvement and external sales. Planting a combination of high -energy plants or forests in the demonstration park. The entire system does not cause pollution to the surrounding environment, and the ecological cycle agricultural model that achieves green energy, ecological development, and breeding. "Lu Liming said.

In Lu Liming's opinion, the transformation of waste such as livestock and poultry manure into resources such as biogas, turning waste into treasure, which not only reduces the pressure of environmental protection, but also expands the channels of farmers' income -to promote the alternative of organic fertilizers and reduce the amount of chemical fertilizer. In addition, increasing organic fertilizer can improve crop resistance, reduce the occurrence of pests and insect pests, reduce pesticide use, thereby saving planting costs, promoting farmers' income, and promoting the use of livestock and poultry manure resource utilization projects. Realize the sustainable agricultural development.

3 Strictly standardized breeding

Keep the "meat basket" in the Greater Bay Area

In recent years, in the face of African swine fever and new crown pneumonia, the reduction of pork supply caused by the impact of the impact of the impact of the impact of the impact of the impact of the influence of the influence of the influence of the pork and comprehensively increased in the transformation and upgrading of the animal husbandry. Become an important measure of "Pork Defense".

After nearly 20 years of development, the Green Lake Farm has grown into a small agricultural leading enterprise in Guangdong Province, which focuses on pig breeding, forestry planting and aquaculture. It is also a veritable "meat basket" base. According to statistics, from 2019 to 2021, the average annual pig farm of Green Lake Farm is more than 100,000 pigs, which mainly supplies cities in the Guangdong-Hong Kong-Macao Greater Bay Area. Among them, the number of pigs in Hong Kong in 2019 reached 120,000, accounting for about 14%of the total number of pigs exported in Hong Kong.

"From the perspective of the province and even the whole country, our company is one of the largest bases in the pig farming industry. It is an important pig supply base in the Guangdong -Hong Kong -Macao Greater Bay Area and even the province." Huang Zukang said how to ensure the supply of pigs. Stable and secure, keeping the "meat basket" in the Greater Bay Area, the company is deeply responsible. To do this, the most important thing is to do a good job of epidemic prevention, especially the epidemic prevention of African swine fever. In his opinion, the biggest risk of the pig farming industry is virus epidemic prevention. Once African swine fever and other epidemics occur, no pigs in the farm will be spared.

The reporter noticed that on the way to Green Lake Farm, there was a slogan of African swine fever epidemic prevention along the way. To enter the Green Lake Farm, the first "level" is to disinfect the vehicle. On the road a few kilometers away from the company, there is a 360 ° automatic automatic anti -kill spray system. All foreign vehicles that will enter the company must be strictly disinfected. At the Green Lake Farm, there are also special rooms at the gate to set up a fully automatic anti -kill spray system to disinfect the personnel entering the company. "Entering the main entrance is the office area. From the office area to the high -rise pig house, there are nearly 2 kilometers. Foreign personnel are prohibited from contacting pigs. Pig farm staff also try to avoid contact with the outside world. Out of the column, you need to be in the work area. "Huang Zukang said. In terms of the quality of pig farming, the Green Lake Farm strictly follows standardized and batch management, and attaches great importance to food safety work. Establish a "five -level management control" and traceability model from procurement approval, inspection, storage, and use to quarantine, and improve the quality and safety management and control system. In addition, the customs department on the 1st and 15th on the 1st and 15th on the field on the field, only the pork on the field was sampled by projects such as prohibited medicines, drug disability, and African swine fever to ensure that the quality of pigs meet export requirements.

Feng Xu told reporters that due to the adopting high -rise pig farming model, since the outbreak of African swine fever, the company's pigs' columns have not only declined, but also increased rapidly from tens of thousands of heads in 2018 to more than 100,000 heads in 2020. "High -rise pig farming has made our company's modern pig farming technical advantage, and the annual outlet of our company will be further increased to 300,000 heads." Feng Xu said.

As early as 2019, Heshan launched the entire county to promote the use of the entire county to promote the project. The Heshan Municipal Government set up a project working group to fully responsible for the promotion of the work.

It is understood that the use of livestock and poultry manure resources in Heshan City mainly involves 56 livestock poultry breeding subjects in the city. Specifically including 41 pig farms, focusing on the construction of rainfall diversion, leakage flooring, solid fluid separation facilities, biogas gas tank, anaerobic fermentation pond, sedimentation tank, heterogeneous fermentation bed, breeding and consumption base, and other auxiliary facilities, etc.; There are 10 broiler farms, focusing on improving the water -saving breeding process equipment, supporting the construction of rain and diversion, chicken manure sheds, and pollution ponds; 2 chicken farms, focusing on the construction of fermented tanks, collecting ponds, etc.; Egg duck farms 1 Home, focusing on the construction of rain and diversion, automatic manure scraping manure and cleaning system; 1 meat pigeon farm, focusing on the construction of fermented tanks, automatic manure clearing equipment, etc.; After the birth, the biogas project with a biogas project with a feces generated by the annual outlets of 100,000 pig farms and an annual power generation of about 10 million kilowatt -hours.

Gu Jinchun, a member of the Party Group and Deputy Director of Heshan Agricultural and Rural Bureau of Heshan City, said that after nearly three years, it has been steadily promoted, and the use of the entire county to promote all projects and fund allocation of livestock and poultry manure resource resources in Heshan City. 10,000 yuan (of which the central government invested 30 million yuan and raised funds of 48.838 million yuan).

"56 projects are mainly transformed and upgraded for large -scale livestock and poultry farms. The manure treatment system has a full amount of feces collecting the use of the field, the use of solid feces, the use of heterogeneous fermentation beds, the reuse of the feces, and the use of sewage fertilizerization. For the functions, the upgraded livestock and poultry farms basically realize the self -existence of feces, handling and comprehensive utilization of their own feces. "Gu Jinchun said.

It is understood that in order to promote the use of livestock and poultry manure resources, the city's organization of large -scale livestock and poultry farms is based on the combination of breeding and poultry farms. Good manure fermentation treatment, implement measures for feces, and achieve comprehensive utilization of waste resources. The main use channels of livestock and poultry manure include organic fertilizer and liquid manure.

As of the end of 2021, the amount of livestock and poultry manure in the breeding farm in Heshan was 690,100 tons, the use of livestock and poultry manure resources was 664,400 tons, and the comprehensive utilization rate of livestock and poultry manure reached 96.27%. The upgraded large -scale farms, supporting advanced manure collection, storage, processing, and utilization facilities to effectively reduce the generation of feces and waste water from the source, control agricultural pollution, and effectively improve the problem of breeding pollution. In addition, large biogas engineering enterprises are uniformly collected, scientifically handled, and deeply processed to be uniformly collected, scientifically handled, and deeply processed to generate biogas, realizing the use of feces, and generating considerable economic benefits.

Gu Jinchun said that through the implementation of livestock and poultry manure resources, the entire county promoted project, exploring the formation of livestock and poultry manure resource -based use of typical models, technical paths, and long -term mechanisms to basically solve the problem of livestock and poultry breeding pollution, promote animal husbandryThe transformation and upgrading of industry to clean environmental protection and efficient circulation, improve the production level of animal husbandry, increase labor productivity and resource utilization, promote the steady growth of major animal husbandry products, and promote the improvement of ecological environment beautification.(Li Lei Feng Yingyao)
