不同移栽期对强化栽培优质杂交水稻生长及产量的影响研究

田间试验研究不同移栽期对强化栽培体系 (SRI)优质杂交水稻生长和产量的影响结果表明 ,幼苗早插可增加低位分蘖数进而促进大穗的形成 ,该措施与稀植结合使水稻形成更多分蘖和有效穗数 ,进而达到高产 ,并节省用种和栽秧用工。

Effect of different transplanting periods on the growth and yield of high-quality hybrid rice in the system of rice intensification

The effects of different transplanting periods on the growth and yield of high-quality hybrid rice in the system of rice intensification(SRI) are studied in this paper. The results show that the early transplantation of the rice seedling can improve the numbers of the tiller at lower position and then prompt the formation of big spike. The combination of this technique with rarely planting method can produce more tillers and more available spikes and achieve the aim of high yield. The experiment proves that the system of rice intensification saves not only the rice seeds but also labors.
