"This year, 545 mu crayfish were raised, with an average yield of about 560 jin per mu. In May, after the early shrimp harvest, rice was planted, with an average yield of about 1000 jin per mu, which can achieve" one water for two purposes, rice and shrimp harvest "." Zhang Wenjun, head of Desheng Family Farm in Changshan Town, Rongxian County, Sichuan, was busy collecting cages and pouring shrimp while chatting
In recent days, the aquatic experts in Rongxian County are also busy. They check the growth of crawfish in the farm, understand the market situation, and carry out technical guidance. "With the climate advantage of no frozen soil in winter and no severe cold in spring, the crawfish in southern Sichuan can come into the market two months earlier than that in Hubei and other major production areas. The price advantage is obvious. The sales time lasts from early February to July every year. During this period, the expert service team irregularly carries out technical guidance on crawfish disease prevention and control." said Yang Yanlin, head of the aquatic station of Rongxian County Aquaculture Center, Last year, the county's crawfish output was about 8300 tons.
In recent years, in order to speed up the construction of the early shrimp industry cluster in southern Sichuan, Sichuan has explored a new path of "rice shrimp co farming", vigorously promoted the expansion and quality improvement of the rice shrimp industry, and formed a new grain economy composite model of "one water for two purposes" and "one field for multiple incomes". The early shrimp industry has become an important focus to promote the increase of people's income and rural revitalization, helping to achieve stable grain and income growth.
On May 17, workers were busy sorting and packaging crawfish in the rice shrimp breeding base in Gongle Town, Xingwen County, Yibin City. Li Gongji, the head of Xingwen County Shrimp Dole Crawfish Breeding Professional Cooperative, said happily: "The supply of early shrimp in southern Sichuan is in short supply. Since February this year, the wholesale price of prawn has exceeded 100 yuan per kilogram at the highest point, and the wholesale price of prawn has also exceeded 60 yuan per kilogram. A large number of orders have been received from Beijing, Shanghai, Shenzhen and other places."
At present, Xingwen County accumulatively develops rice shrimp breeding area of about 67000 mu, with an annual output of about 4500 tons, of which a large number of crayfish are sold by air. In order to solve the transportation problem, Yibin Early Shrimp Industry Federation and other officials officially signed the "Agreement on Air Transportation Service of South Sichuan Early Shrimp" with Yibin Airport Airport Logistics Co., Ltd., and South Sichuan Early Shrimp won nearly 10 preferential price and service priority air logistics transportation rights and interests, with a maximum reduction of about 50 cents per kilogram in comprehensive cost.
"We not only help solve transportation problems, provide free training for rice shrimp farmers in breeding technology and other aspects, but also provide support in seedling breeding, breeding standards, brand building, market promotion and other aspects." Guo Wanliang, director of Xingwen County Animal Husbandry and Aquaculture Development Service Center, said that in recent years, Xingwen County has explored "leading enterprises+professional cooperatives+farmers" The mode of "" will lead the development of the rice shrimp industry, gradually promote the "Xingwen Stone Sea Crawfish" and other crawfish brands, and will also spare no effort to build a rice shrimp whole industry chain integrating seedling breeding, three-dimensional breeding, Internet of Things circulation, intensive processing, and catering consumption, and strive to reach 100000 mu of rice shrimp area in the county during the "14th Five Year Plan" period, with an annual output of 20000 tons, and achieve "rice bags" and "vegetable baskets" The "money counter" is organically unified.
Longchang, Neijiang, is also a major breeding city in Sichuan. The output of Procambarus clarkii accounts for about 16% of the whole province, ranking first in the province. Zhong Hui, director of Longchang Municipal Bureau of Agriculture and Rural Affairs, said that "rice shrimp farming" can produce about 1000 jin of high-quality rice per mu, 250 jin of high-quality aquatic products, and the average output value per mu is more than 7500 yuan, which is more than 3800 yuan more than the conventional rice monoculture. In 2023, the annual output of high-quality rice and paddy shrimp in Longchang City will reach 198800 tons and 11600 tons respectively. The new grain economy compound model of "one field with multiple harvests" has broadened the path for farmers to become rich.
