稀播培育壮秧,是提高晚稻单产的基础;但单纯强调稀播而不相应减少栽插本数,就必须扩大秧田面积,减少早稻面积和复种指数。过去采用的“两段育秧”和“抽条留苗”办法,因技术性较强、费工较多,在大面积实践中还受到一些限制。近几年来,随着杂交稻的推广,稀播细本栽培法已为广大农民所掌握,如能应用于常规晚粳,不仅便于推广应用,而且能在更大的范围内发挥稀播壮秧的增产效益。

Sowing nursery seedlings is the basis for improving yields of late rice; but simply emphasizes thinning without corresponding reduction in planting this number, we must expand the area of ​​seedling, reducing the area of ​​early rice and multiple crop index. In the past, the “two-stage seedling-raising” and “drawing and stubble removal” methods were more restrictive because of their strong technical skills and more labor costs. In recent years, with the popularization of hybrid rice, thin planting thin cultivation method has been mastered by the majority of farmers, as can be applied to conventional late japonica, not only to promote the use of, but also in a broader context of play thin seedlings Yield increase.
