[Comprehensive promotion of rural revitalization] Rice Yellow Crab Fat -"Science and Technology Courtyard" photo of Nanzi Village

In the golden autumn season, the beauty of rice fields, crab fat. At the demonstration base of the integrated cultivation of rice and fishing in Gongzhuling City, the ears of rice are full, and the river crabs are in groups. In the fragrance of rice, not only is it full of good harvest, but also reflects a group of "new farmers" that actively adapt to market demand and actively adjust the industrial structure and business methods.

Nankaizi Street is adjacent to the Dongliao River and 4 rivers. The terrain is flat, the rain and heat are the same period, and the water sources are sufficient. These are favorable conditions for planting rice. In 2018, Wang Qiulu and Wu Yan's husband and wife brought their graduate students to the Nanyangzi Village Breeding Base to set up a "Science and Technology Council" at the Nanyangzi Village Breeding Base.

In less than 5 years, this group of "new farmers" dispelled the stereotypes of the villagers with wisdom and sweat, and broke through the bottlenecks in the process of "South Shrimp Raise", accumulated accurate regional accurate region The scientific research data of Huaowan breeding enlarge the villagers' "wallets" ...

As of now, the cooperatives have 110 hectares of rice and 18,000 kilograms of rice per hectare, which has attracted nearly 50 local villagers to join. Traditional rice fields earn 10,000 yuan per hectare, and now light -water products can earn 5,000 yuan. In addition, rice is planted under pollution without pollution, and the market price doubles. After breeding, the weight of the crab can reach 137 or eight. Due to climate reasons this year, the price of crabs may have 20%of the growth space. Compared with only rice, the rice field crab cultivation model and integrated technology with "bilateral grooves+measuring rice seedlings" have increased from the original 550 yuan/mu to 1100 yuan/mu; The comprehensive profit can reach 1900 yuan/mu, and the benefits increase by about 1,300 yuan/mu compared to a single planting rice.

Grand Grapho Feng Deng not only comes from the wind and rain from nature, but also cannot be separated from the improvement of the comprehensive production capacity of food supported by agricultural technology. Crab can remove weeds in rice fields, eat pests, excrement can fat fields and promote rice growth; while rice also provides rich natural bait and good habitats for crabs, mutual benefit, and form a benign ecological cycle. The exploration of the new model brings the efficient utilization of rice planting, and also improves the utilization rate of rice ears and shrimp and crabs. While enriching the paddy field by -products, the rice fishing comprehensive breeding model further consolidates the foundation of food production capacity and enhances the quality of rice.

The key to implementing the "Tibetan Grain in Technology" is to adhere to agricultural scientific and technological innovation. Since 2018, Wang Qiuju has led the team to repeatedly experimented and actively explored, formed intermediate cultivation technology, and successfully explored the intermediate cultivation technology of the blackhead of the Kerracelite (crayfish). They also studied the river crab bait that is suitable for the rice field environment. It has now successfully explored the best protein, fat, and eggine ratio suitable for rice field crabs. Experimental data in 2021 shows that intermediate cultivation technology has improved the survival rate of crayfish, reaching 60.25%. Wang Qiuju said: "This year we have made new explorations in terms of bait, from the exploration of large nutrients to the need to be adjusted for the need for essential amino acids. This exploration cannot be separated from the support of all parties. Only the support of support, the joining of business entities, and the active participation of farmers can have today's industries and scientific research results. "

With the decline in traditional planting benefits, the market's demand for green high -quality agricultural products is growing. How can we make money more? The transformation method is the answer they give by action. The rice field loach, rice duck symbiosis, rice and fish symbiosis, rice crab symbiosis may be symbiosis in the future, and more and more "new farmers" have a diversified attempt in rice fields. It can be said that the "income of rice and fishing" mode reflects the adjustment of the planting method. Perhaps in the rice fields in the future, while seeing the golden rice ears, we will also see crab fat shrimp jumps, and frogs are called cicadas. With the increasingly perfect scientific research, good varieties, processing, packaging, and sales of the green rice industry chain, a new "road" with ecological priority and green development will also appear in front of the public.
