花生氮肥施用问题,在实践上和认识上说法不一。广东粤西地区群众对花生施用基肥十分重视,一些地方有在前作多施肥的经验。七十年代出现花生高产田块后,为了获得高产,偏重施氮肥的现象较为普遍,招致徒长倒伏,肥多反而不增产或减产。为此,我们从1982年春至1989年秋开展氮肥施用技术研究,为提高花生产量提供合理使用氮肥的科学依据。一、设计和方法(一)不同施氮量试验1、不施氮磷钾,基肥亩施石灰25公斤(简称无肥区)。 Application of peanut nitrogen fertilizer, in practice and understanding vary. People in western Guangdong, Guangdong Province, attach great importance to the use of peanut-based fertilizer, some places have more experience in fertilization. In the seventies peanut high yield plots appear, in order to obtain high yield, emphasis on nitrogen fertilizer is more common phenomenon, resulting in leggy lodging, fat but not increase or decrease production. To this end, we conducted from the spring of 1982 to the autumn of 1989 to study the application of nitrogen fertilization, in order to improve the yield of peanut to provide a scientific basis for the rational use of nitrogen fertilizer. First, the design and methods (A) of different nitrogen rate test 1, without N, P, K fertilizer 25 kg base fertilizer (referred to as fat zone).
