杂交水稻再生利用是一项投资省、花工少、产量高、效益好的栽培制度。尤其是在全年种一季水稻热量有余,种两季水稻热量不足的山区,更有推广应用的价值和广阔的前景。我县通过几年来的示范栽培,取得较好效益,并积累一些经验。现将该项技术要点介绍如下:
Hybrid rice recycling is an investment province, less flower workers, high yield and good efficiency of the cultivation system. Especially in the whole year, there is more rice in one season and less rice in two seasons, so it has more promotion and application value and broad prospects. My county through years of demonstration cultivation, obtain better benefits, and accumulated some experience. Now introduce the technical points are as follows:
