花生从种子播种到新种子形成,根据品种类型的不同,整个生育期110~180d之间,大体上可以分为种子发芽出苗期、苗期、开花下针期、饱果成熟期四个阶段。目前,花生产量不高的主要原因是:开花多,结果少;秕果多,饱果少。提高花生产量除了从选用优良品种、适期播种、合理密度、防病治虫、适时收获等方面重视外,还应从加强各生育时期的栽培管理方面加以重视。
Peanut sowing from seed to new seed formation, according to the different types of varieties, the entire growing period of 110 ~ 180d, can be divided into seed germination at seedling stage, flowering needle, full fruit ripening four stages. At present, the main reasons for the low yield of peanuts are: more flowering and fewer fruits; In addition to increasing the yield of peanut from the selection of good varieties, sowing, reasonable density, disease prevention and control, timely harvest and other aspects of attention, but also from strengthening the cultivation and management of each growth period to pay attention.
