Integration Demonstration of High-Yielding Cultivation Techniquesof Double Cropping Hybrid Rice and Its Development Strategies in Hengnan County
From 2021 to 2023,Hengnan County organized and implemented a large-scale high-yield demonstration of double cropping hybrid rice.On the basis of summarizing the achievements of high-yield research and demonstration of double cropping super hybrid rice in Hengnan County,a set of high-yield cultivation techniques for double cropping hybrid rice were integrated.At the same time,in response to the problems existing in the sustainable development of this model,development strategies were proposed from improving the production efficiency of double cropping rice,enhancing scientific and technological support,strengthening farmland infrastructure construction,and strengthening technical training,to pro-vide reference for the sustainable development of the double cropping hybrid rice model.
