China News Service, Yiyang, October 21 (Song Mei) "According to the current harvest situation, this year’s rice and crab fields have increased by an average of 40% over last year. The crabs were caught." On October 21, at the rice field crab comprehensive breeding base in Dadongkou Village, Jinpen Town, Datonghu District, Yiyang City, Hunan Province, the person in charge Xu Tiejun and his wife calculated 316 acres of rice crab fields this year while catching crabs. Income.
Thanks to the management and protection, the net profit value of rice and crab fields per mu will reach 3,000 yuan this year, and the total output of crab fields will exceed 2 million yuan.
51-year-old Xu Tiejun and his wife have been working around agriculture all their lives.
From the sale of agricultural machinery to rice planting to the establishment of professional cooperatives, for 17 years, they have continued to innovate the development model of rice fields, practice scientific interplanting of major agricultural products in the Dongting Lake area such as rice, shrimp, and crabs, and explore more traditional agricultural "butterfly changes" to become rich Road, successfully realized the dream of "a field with dual uses, one water for double harvest, and a win-win situation for planting and breeding".

At present, Xu Tiejun’s cooperative has a circulation area of more than 3,600 acres, with 186 permanent workers, among whom poverty households account for over 37%, agricultural mechanization equipment reaches 48 units, and total assets exceed 5 million yuan.
Xu Tiejun and his wife, who can rely on farming to enter a well-off road, apart from their persistent efforts for many years, they are also inseparable from the state's uninterrupted support policies for agriculture, as well as the continuous transformation of policies into endogenous policies by provinces, cities, and districts in accordance with local conditions. The whole process of force "assistance".
"This year's rice and crab intercropping can usher in a'double harvest'. The key is to use the technology well. Shanghai Ocean University has provided technical guidance throughout the process, especially during the critical period of rice field growth and crab shelling. Technical experts are stationed in the village. "Looking at the plump crabs and the full-grained rice in the rice fields, Xu Tiejun attributed the primary factor for his successful practice of "eating crabs" to the full technical service assigned by the district.
In order to achieve the agro-ecological transformation goal of "one field with two uses, one water for double harvest, and a win-win situation for planting and raising", in 2019, Datong Lake District and Shanghai Ocean University signed a technical cooperation framework to realize long-term deployment of expert teams to grow rice and crabs for farmers Provide technical guidance.
After nearly a year of continuous exploration and exploration, the expert team used the unique weak alkaline soil and water quality of Datong Lake to overcome the "water" problem with "grass" as the medium. According to the unique growth conditions of rice and crabs, they explored a set of problems. The "cheat" of the "symbiosis and co-growth" of the two: before the seedlings heading, the crab seedlings are placed in the ring ditch of the rice field where aquatic plants have been grown, and then the crabs are placed in the rice field after the heading. In multiple ecological cycles such as harmful organisms and crab manure fields, a new modern ecological three-dimensional agricultural development model will be established that "grass is for water purification and'quality', crabs are for rice to enrich and'quantity', and rice is for crabs to add'fragrance'". .
Through practice, the average output value per mu of the first batch of rice and crab intercropping farms is nearly 7,000 yuan, which is three times higher than the output value of ordinary rice fields.
The first batch of planting and raising farmers who tasted the sweetness began to expand the area of planting and breeding, and drove more rice farmers to join it.
Up to now, the Datong Lake District has developed a total area of 3,000 mu of rice and crab interplanting, and the total output value this year is expected to exceed 20 million yuan.

Datong Lake District, located in the hinterland of Dongting Lake, is rich in high-quality agricultural products. As the golden signature brand Datong Lake rice and Datong Lake hairy crabs are well-known at home and abroad for their unique taste and quality.
In recent years, the Datong Lake District has made every effort to ensure the source of food security on the basis of actively responding to the country’s various agricultural policies.
Combining with the characteristics of agricultural regional development, Datong Lake has continuously polished the signs of high-quality agricultural products such as "rice", "crab" and "fish". Through long-term cooperation with universities in industry, academia and research, and the introduction of agricultural innovation and development awards and supplementary rules, scientific exploration of new " Various interplanting modes such as rice + fish, "rice + shrimp", and "rice + crab" continue to make the traditional farming "cake" bigger, stronger and better.
