花生的中后期是指从开花下针到荚果成熟这一阶段,生育特点是由营养生长和生殖生长并进逐步转入以生殖生长为主。花针期生长过旺,易徒长影响开花下针,后期往往造成倒伏不能高产;生长较弱,对开花下针不利,影响养分的运输和积累。因此,必须加强高产花生的中后期管理。 Peanut in the latter part of the flowering from the needle to the maturity of this stage, the characteristics of reproductive growth by the vegetative and reproductive growth and gradually into the main reproductive growth. Needle growth period is too fast, easy to affect the long legs under flowering, the late are often caused by lodging can not be high yield; growth is weak, unfavorable flowering under the needle, affecting nutrient transport and accumulation. Therefore, it is necessary to strengthen the middle and late management of high yield peanut.
