近日,有的农民打来电话,反映自己种植的地膜花生烂果现象非常严重,测算亩产量也就在三、四百斤,仅为普通田产量的一半。经调查得知,出现花生烂果现象严重的原因有以下几点:一是花生品种陈旧,亟待更换优良高产花生新品种,在一些地方,好多农民仍然使用冀油4号、鲁花7号、鲁花9号等产量低下,抗病力差的品种。二是栽培模式不科学。有的农民采用了平畦上面覆盖地膜的方法,造成了土壤通透性差,极容易造成烂果。三是病虫害所致。花生在生长期,如遇到病害,或荚果遭到虫咬极容易发生烂果。四是施肥方法不科学,营养不平衡,植株的抗逆性降低,导致了烂果现象的发生。
Recently, some farmers called and said that the phenomenon of degeneration of rotten peanuts grown on their own was very serious. The measurement of mu yields was also three or four hundred jin, only about half of that of common fields. The investigation shows that there are many reasons for the serious rotten peanuts: First, the peanut varieties are outdated and new peanut varieties with good quality and high yield are in urgent need of replacement. In some places, many peasants still use Ji-You No.4, Luhua No.7, Lu Hua 9, such as low yield, poor resistance to disease varieties. Second, cultivation mode unscientific. Some peasants adopted the method of covering the plastic film on the flat surface, resulting in poor soil permeability and extremely easy to cause rotten fruit. Third, pests and diseases caused. Peanuts in the growing season, such as the case of disease, or pod bite susceptible to rotten fruit. Fourth, unscientific fertilization methods, nutrition imbalance, plant resistance decreased, resulting in the phenomenon of rotten fruit.
