"Questioning" crops and waterlogging disasters to improve farmland production capacity

[China Agricultural Machinery Industry News] September 22-23, National Public Welfare Industry (Agriculture) Research Project "Research and Demonstration of Key Technologies for Prevention and Control of Major Crop Waterlogging Disasters" 2016 Anhui Demonstration Zone Site Meeting Held in Hefei, from Nearly 40 research experts on crop waterlogging disasters from 10 participating research institutes gathered together to “review the main crops”.

"Questioning" crops and waterlogging disasters to improve farmland production capacity

On the same day, the participating experts visited the low-lying rice fields in the low-lying paddy fields of the county, and the demonstration samples of the green high-yield cultivation techniques of the lotus roots and the green production and efficiency-enhancing technology demonstrations of the rice and the disaster prevention and reduction in Guohe Town.

In recent years, in order to improve the resistance of regional rice production to natural disasters, our county has actively adjusted the planting structure, targeting low-lying rice fields with high frequency of disasters and suitable for the development of aquatic vegetables, and promoting the cultivation of lotus roots as the main aquatic vegetables. At present, the planting area of ​​lotus root has reached more than 70,000 mu. In the total demonstration area of ​​3,000 mu of Guohe Town, the model of green production and efficiency improvement of rice mitigation and disaster reduction, mainly demonstrates the optimization of planting systems and models for avoiding locusts, reducing disasters and increasing efficiency along the Yangtze River, integrating rice quarantine prevention, control and compensation. Biotechnology, to achieve avoidance, reduce disasters, increase efficiency, stabilize production, increase production and increase efficiency.

After the disaster occurred this year, the county party committee and county government invited the experts of rice pickling prevention and control technology in Anhui Province to go deep into the demonstration area, and guided the affected farmers to carry out rapid recovery and replanting after the rice disaster according to the basic conditions of the farmland and the degree of disaster. At present, more than 95% of the plots in the demonstration area can reach 80% of the estimated output, ensuring the yield of rice fields.

A member of the project expert group, Chen Yingzhi, a researcher at the National Agricultural Technology Promotion Center, said that the self-rescue and recovery comprehensive technology after rice flooding disasters has been well used and demonstrated in Beibei Village of Guohe Town, and the disaster reduction effect is obvious. Prof. Tian Xiaohai from Yangtze University praised the observation scene provided by the county for the meeting. He believed that Qijiang County combined with local agricultural practices and adopted a series of measures of “adjusting structure, providing facilities and strong support” to effectively improve farmland production. The ability, especially for the low-lying rice field reconstruction and flood-prone areas in the flood-prone areas of the reclamation area, implements scientific prevention and control technology, and fully utilizes the rice control, control and growth-promoting compensation technology of rice stalks along the rivers and lakes, and improves the rice production resistance in the region. Reverse disaster mitigation capabilities. The demonstration site of Lujiang County demonstrated the innovation, adaptability and vitality of rice mulch disaster prevention and control integration technology in rice production.
