初步提出了双季稻免耕抛秧栽培稻田的稻茬与杂草灭生处理技术，包括适用除草剂类型、处理适宜时间、数量及使用方法等；首次在不同生态类型大田验证了双季稻田采用完全除去犁翻耕耙的免耕抛秧栽培技术的可行性，同时提出通过改进传统耕作栽培技术水平以适应免耕抛秧稻生育特性对提高免耕抛秧栽培穗粒数与产量水平的可能性 The technology of eliminating stubble and weeds in double cropping rice in no-tillage and throwing rice field was preliminarily put forward, including the types of herbicides to be used, the suitable time, quantity and using method of them; the first time in different types of ecological field, The feasibility of using no-tillage and throwing seedling cultivation technology to completely remove the plow tillage rake is put forward. At the same time, it is proposed that improving the tillage and seedling yield of no-tillage and throwing seedlings by improving the traditional tillage and cultivation techniques to adapt to the growth characteristics of no- possibility
