近年来,许多农户反应,化肥没少用,钱没少化,花生地上部茎叶生长也正常,但就是收获的时候荚果往往粒秕甚至空壳,产量低。一、引起花生秕粒空壳的主要原因1.土壤保水保肥能力差引起的。保水保肥性能差的山塂薄地和沙地发生重,而保水保肥性能好的潮棕壤土不发生。部分地块有机肥连年施用不足,造成土壤保水保肥能力差,引起花生秕粒空壳。有机肥料营养全面,可以持续稳定的供应作物生长,同时有机质在土壤中有很好的调节作用,对各种生理病害可以起到明显的缓冲作用。2.土壤酸化引起的。常年、大量、不科学施用化肥,尤其是氮素化肥,致使
In recent years, many farmers responded that the fertilizer was used less, the money was not reduced, and the stems and leaves of peanut above ground were also normal. However, when harvesting, the pods were often clumped even with empty shell and the yield was low. First, the main cause of peanut pellets shell 1. Poor soil water retention and fertilizer caused. Water retention and fertilizer poor performance of mountain shady thin and sandy areas occur heavy, and water and fertilizer and good tidal brown soil does not occur. Some plots of organic fertilizer year after year, inadequate, resulting in poor soil water retention and fertility, causing peanut grains empty shell. Organic fertilizer nutrition is comprehensive, sustainable supply of crop growth, while organic matter in the soil has a good regulatory role for a variety of physiological diseases can play a significant buffer effect. 2. Soil acidification caused. Perennial, large, unscientific use of fertilizers, especially nitrogen fertilizers, resulting
