花生生长后期是指田间50%的植株出现饱果到最后成熟收获的一段时间,其生理特点是营养生长逐渐衰退、停止,荚果逐渐充实饱满,增加的果重一般占总果重的50%以上,是荚果产量形成的主要时期。这一阶段的管理重点是养根保叶防早衰、活熟到老增果重,主要管理是做到“五防”。防徒长。有一些地力较好,肥料施得较多,特别是氮素化肥施得较多的田块,在生长后期最易出现植株徒长。今年,南方花生产区5、6月连续两个月来的多雨与暴雨天气,是历史上少有的,
Peanut late growth refers to the field of 50% of the plants full of fruit to the final ripe harvest for some time, its physiological characteristics is the gradual decline of vegetative growth, stop pod gradually full full, the increase of the weight of the fruit generally account for more than 50% of the total weight , Is the main period of pod production. This stage of management focus is Yangguoba leaf prevention and premature senility, live to the old fruit weight gain, the main management is to achieve “five defenses ”. Prophylaxis long. There are some better fertility, fertilizer more facilities, especially nitrogen fertilizer to give more plots, the most likely to appear in the late growth of plant growth. This year, the rainy and stormy weather in the southern flower-producing area in June and June for two consecutive months is rare in history,
