In late August, it was during the maturity of rice. In the 1,000 acres of rice fields in Alida Village, Alida Township, Fuhai County, a plant of rice swayed with the wind, and the rice fragrant came. , Aya seedlings play in the water.

"Rice can provide a suitable growth environment for fish fry. Hidden space can help them avoid enemy creatures. Small fish fry swimming in the fields is just for rice pine soil. Their excrement is conducive to improving the content of soil organic matter. At the same time, these fish fry can be eaten with animals and plants in the water, and they can also help remove weeds and pests in the fields, so that weeds in the rice fields gradually become less. "Liu Rongfei, a big farmer, said.

In 2020, through the form of "branch+company+cooperative+farmers", Alida Township cooperated with Heilongjiang Hongxinglong Nonglong Farming Rice Farmers' Professional Cooperative to establish Fuhai County Fujia Rice Agricultural Development Co., Ltd. Essence

In order to improve the output value of cultivated land and achieve high yield and efficiency, this year, after a comprehensive inspection, Liu Rongfei decided to develop a new model of ecological breeding of rice and fish and crab symbolism on the basis of the development of rice and crabs.

"The symbiosis of rice, fish and crab" is to raise fish and crabs in the rice fields, so as to achieve ecological functions such as controlling diseases and insect pests, regulating the climate, maintaining water and soil, and conservation of water. Essence

Liu Rongfei contracted 1,000 acres of water fields in Alida Village. In spring, 90%of the paddy fields are planted with fragrant and glutinous rice flower fragrance, and 10%of them are crab and fish.

At present, Liu Rongfei's rice fields have cultivated 100,000 flower catfish, white catfish, grass carp, and large -eyed larvae. The catfish seedlings in May this year have grown to 20 cm long. "".

"The whole process of rice and crab comprehensive breeding does not apply fertilizer and pesticides, which also guarantees the green quality of rice." Liu Rongfei said.

Liu Rongfei calculated the account: 1 acre of rice fields can produce 450 kg of rice, 60 kg of crab and 15 kg of fish fry. The rice per kilogram of rice is calculated at 15 yuan, and the income of the acres is 6750 yuan. The fry per kilogram of fry is calculated at 15 yuan, and the income per mu is 225 yuan. These three revenue plus up, 1 acres of rice fields have a benefit of about 12,000 yuan, which is twice as high as pure planting rice.

For the future, Liu Rongfei has a longer -term plan. "The paddy fish can increase the added value of green agricultural products. On this basis, I plan to launch rice field tourism, paddy field research, etc. to further enrich the function of rice fields."
