水稻的返青期是指水稻插秧之时到随后叶片重新伸展的一段时间。返青期随后而来的是大田的有效分蘖,而有效分蘖对产量有着密切的关系。一般来说,返青期越短,则水稻移栽后进入正常生长的时间就越早,产量就更理想。缩短移栽后的返青期与多种因素有关。缩短晚稻的移栽返青期需要注意以下几个方面:1.培育壮秧秧苗是缩短返青期的重要基础条件。壮秧能够比徒长的秧苗具有更好的抗植伤效果。培育壮秧,需要应用优良稻种、把握播种密度、进行配方施肥、搞好浅水管理、
The turning-back period of rice refers to the period of rice transplanting to the subsequent extension of the leaves for some time. Returning to Green is the effective tillering field, and effective tillering on the yield has a close relationship. In general, the shorter the rejuvenation period, the earlier the rice will be in normal growth after transplanting and the better the yield will be. Shorten the greening after transplanting and a variety of factors. Shorten the late rice transplanting cycle need to pay attention to the following aspects: 1. Breeding strong seedling seedling is to shorten the greening important basic conditions. Strong seedlings can have a better anti-implant effect than the slim seedlings. Nurturing strong seedlings, the need to apply good varieties of rice, seeding density, formula fertilization, improve shallow water management,
