黄海稻区优质米品种越光防倒伏栽培技术

Cultivation Techniques of Lodging Resistance for High Quality Rice Variety Koshihikari in Yellow Sea Rice Area

黄海稻区与优质米品种越光的原产地日本新泻县纬度接近,气候条件相似,生产的越光稻米品质佳,但在种植过程中存在的最大问题是倒伏。在多年生产实践中总结出适宜越光的抗倒伏栽培管理技术,包括建立合理的耕作制度、改进育苗方式提高秧苗素质、确定合理的株行距、科学进行水肥管理及病虫害防治、喷施二甲四氯钠等。

The Yellow Sea rice region is similar to Niigata Prefecture,Japan,which is the origin of high quality rice variety Koshihikari.The climate conditions are similar,and the quality of Koshihikari is better.However,the biggest problem in the planting process is lodging.In many years of production practice,the suitable lodging resistance cultivation management technology for Koshihikari was summarized,including establishing reasonable tillage system,improving seedling raising method for seedling quality,determining reasonable plant row spacing,scientific management of water and fertilizer,pest control,and spraying of MCPA-Na,etc.
