As soon as I got out of the car, I smelled a lot of rice. When we came to the salt -alkali rice planting base in Hanting District, Weifang City, Shandong Province, the green rice swinged with the wind, and the ears of the rice had been revealed. Soil's salt content, benefit analysis, growth decision -making suggestions ... On the display screen of real -time data monitoring centers, tens of thousands of acres of salt -alkali rice growing clearly.

"At present, it is in the period of pumping and flowering, and it is expected to be harvested at the end of October. The area of ​​salt -alkali rice planting is 58,000 mu, the estimated output is 37,000 tons, and the output value is about 230 million yuan." Tian Guoqing, general manager of Shandong Binyuan Agricultural Technology Co., Ltd. It is said that at present, saline -alkali rice research and development and processing derivatives exceed 70 species.

From September 7th to 8th, the comprehensive utilization of salt -alkali land hosted by the Ministry of Agriculture and Rural Ministry and the Shandong Provincial People's Government was held in Weifang City, which attracted the ambassadors from Australia, the Netherlands and other countries. Experts and other more than 180 people attended the meeting.

Participants conducted discussions and exchanges on the theme of "comprehensive utilization and food safety of saline -alkali land and food" on the theme of "comprehensive utilization and food safety" of salt -alkali land.

The reporter learned from the meeting that saline -alkali land was widely distributed around the world and was once called the "terminal illness" of land. The area of ​​saline and alkali land in my country is about 1.5 billion acres, of which about 500 million acres of saline and alkali land available. Waking up this "sleeping" resources can effectively increase land increase and achieve the expansion of the capacity of cultivated land resources, improve quality, and increase efficiency.

"According to Chinese practice, the average yield per hectare can be 6 tons per hectare of salt -alkali land. If global saline -alkali land can be used more by 1%, it is equivalent to an increase of 50 million tons in the world. 100 million people need to use grain in one year. "The relevant person in charge of the Ministry of Agriculture and Rural Ministry said.

According to reports, in recent years, the Ministry of Agriculture and Rural Affairs has implemented a series of measures to coordinate the promotion of scientific research, technical demonstration, and development and utilization of saline -alkali and land improvement, which has achieved significant results.

According to the characteristics of different saline -alkali areas, my country has established dozens of sets of saline -alkali soil efficient use of technical models to promote comprehensive utilization of saline -alkali and land into the fast lane. For example, Shandong Province has transformed 5.8 million acres of salt -alkali cultivated land, created 11 innovative platforms such as the comprehensive utilization of national saline -alkali and land comprehensive utilization technology innovation centers, saline -alkali biological resources and evaluations, and used key laboratories to cultivate more than 200 new species of saline -tolerant.

In the past, Liuhu Town, Dongying District, Dongying City, Shandong Province, can only plant cotton -resistant crops such as cotton. Local implementation of soil improvement in the low -production fields of severe saline -alkali, scientifically carried out irrigation of the Yellow River hydraulic alkali, and enhance the nutritional supply capacity of crops. At the same time, it is preferably varieties of saline -alkali land. Revenue of nearly 40 million yuan.

At present, the concept of governance of saline -alkali land in my country has changed, from adapting to plants in the treatment of saline -alkali land, to selected saline -tolerant plants to adapt to saline -alkali land. Xu Xing, a professor at Ningxia University, said that Ningxia researchers have selected new saline -resistant varieties such as wolfberry, corn, rice, and grapes on the saline -alkali land of Heba Plain, and "put" colorful coats for the white saline -alkali land.

The world's soil salinization and secondary salt staining issues restrict the sustainable development of agriculture, and strengthening the improvement of saline -alkali land is of great significance to ensuring the security of the world. The international representatives of the conference believe that the conference shows China's high attention to soil health and its responsibility in the international food and agriculture field.

For the United Nations Food and Agricultural Organization in China, Wen Kangnong said that many countries are striving to promote the comprehensive utilization of saline -alkali land. Among them, China has introduced policies and measures, strengthened scientific research, focused on pragmatic cooperation, and helped global soil health and food safety.

The comprehensive utilization of saline -alkali land is a world problem that needs to be continuously deepened. At the conference, the "Initiative of the International Conference of Salt and Alkali Land Comprehensive Utilization of the International Assembly" appealed that countries should jointly carry out the work of salt -alkali resources, dynamic monitoring and evaluation, technical research and development and promotion, and improve relevant laws, regulations and policies and measures, and strengthen international exchanges for soil health.

"We must continue to deepen international cooperation, promote the comprehensive utilization of saline -alkali land, and maintain global food security," said the relevant person in charge of the Ministry of Agriculture and Rural Ministry.
