[China Agricultural Machinery Industry News] On the 28th, the Fujian Academy of Agricultural Sciences invited domestic counterparts to go to Guanzhuang Village, Sha County, Sanming City, to promote the agricultural technology extension of the Ministry of Agriculture's major agricultural technology extension service hosted by Xie Huaan, an academician of the Chinese Academy of Sciences. The construction of the service system will carry out on-site inspection and production acceptance of the first season rice production.
Regeneration rice is rice that is sown once and harvested twice, that is, the first season rice does not need to be sown after harvesting, and can be harvested again after 60 days, saving 500 yuan per mu.
Regeneration rice cultivation mode breaks through the whole process of mechanized production
In view of the problem that China's agricultural labor cost has exceeded 50% of total production cost, rural labor shortage, and farmers' willingness to grow grain, in recent years, Academician Xie Huaan organized a team of Fujian experts to carry out the whole process of mechanized chemical technology and technology promotion of reclaimed rice. In 2015, in the demonstration of Guanzhuang Village in Sha County, the demonstration of low-remaining piles of reclaimed rice was carried out. The average yield per mu of the 100-acre paddy rice was 453 kg per mu, and the average yield per mu in the regeneration season was 272 kg. The average annual yield per mu was 725 kg.
In the Hongjian family farm in Guanzhuang, Shaxian County, the mechanized transplanting of the expert group was “Yuyou 2640†and “Yu Youmingzhanâ€. The first season rice yield was 578 kg and 521 kg, respectively. The spokes accounted for 383 kilograms of rice in the first season, and the average yield per mu was 494 kilograms.
Chen Dazhou, deputy director of the Jiangxi Academy of Agricultural Sciences, believes that as a resource-saving and light-cultivated rice cultivation model, reclaimed rice has broken through the whole process of mechanized production, with short growth period, high yield, excellent rice quality and provincial province. Workers, reducing costs, increasing income from agriculture, etc., can provide a technical guarantee for national food security.
At present, the annual harvested area of ​​recycled rice in Fujian Province is 800,000 mu, and the machine plug-in machine accounts for 30%. The person in charge of the Shaxian County Agricultural Bureau introduced the 20,000 mu of rice in the county's reclaimed rice year, and the machine inserts accounted for 25%. The demonstration potential for expanding the whole process of methanation of reclaimed rice is great.
It is understood that the high-yield demonstration of reclaimed rice in Youxi County of Fujian Province ranks first in the country. From 2000 to 2015, the average annual yield of recycled rice in the county is 890 kg, accounting for 32% of the county's sown area, and rice production accounts for 45% of the county. %.
The area of ​​ratoon rice planted in the nine provinces of southern China is 11 million mu, and the average yield per mu in the regeneration season is only 136 kg. Experts estimate that there are 160 million mu of single-contract rice fields in the southern rice-growing area of ​​China, and 50 million mu is suitable for the promotion of reclaimed rice. If it can break through the mechanized demonstration of the whole process of reclaimed rice and reach the high production level of Youxi and Shaxian, it can increase the annual output for the country. The 20 billion kilograms of rice has important strategic significance for China, which accounts for only 7% of the world's cultivated land and 22% of the world's population.
To this end, the Ministry of Finance and the Ministry of Agriculture of the People's Republic of China have successively issued supporting policies for accelerating the whole process of mechanization demonstration and promotion of agricultural production, piloting the whole process of mechanized social services for agricultural production, accelerating the reform of agricultural supply-side structure and the transformation of agricultural development mode, and ensuring national food. Safety.
