提高花生单产,除良种外,施肥是一个重要的技术环节。过去曾认为花生的根部有根瘤菌共生,中后期施肥没有必要。近年来我们根据花生花芽分化、荚果发育和子房柄生长生理等的研究,采用增施花前肥、壮果肥,后期根外追肥的方法获得较显著的增产效果,并通过多点的生产实践,受到农民群众欢迎。目前在番禺县、增城县已有8成以上,东莞县有5成以上面积采用这种施肥方法。 Improve peanut yield, in addition to good seeds, fertilization is an important part of the technology. In the past, it was thought that the roots of peanuts had rhizobia symbiosis, and fertilization was not necessary in the middle and late stages. In recent years, according to the peanut flower bud differentiation, pod development and the physiological growth of the sub-stalk physiology, the use of additional fertilizer before and after, the late fruiting topdressing method to obtain more significant yield increase, and through more production practices , Welcomed by farmer masses. Currently in Panyu County, Zengcheng County has more than 80%, Dongguan County, more than 50% of the area using this method of fertilization.
