一、轮作间套。马铃薯是一种需钾量较大的作物,连作地钾等营养元素严重缺乏,影响马铃薯块根的膨大;同时连作地金龟子幼虫、蝼蛄等地下害虫危害猖撅,病害发病率明显高于轮作地。马铃薯与水稻、油菜、麦类、玉米、黄豆等作物轮作比较好,既利于减少病害的发生,也利于减少杂草生长。马铃薯属茄科作物,因而不能与辣椒、茄子、烟草、西红柿等 First, the rotation between sets. Potato is a crop with a large amount of potassium needed. The serious shortage of nutrients such as potassium can affect the tuberous root enlargement. At the same time, the underground pests such as scarabs and crabgrass are endangered, and the incidence of diseases is obviously higher than that of crop rotation. Crop rotation between potatoes and rice, rapeseed, wheat, corn and soybean is better, which helps reduce the occurrence of diseases and helps to reduce weeds growth. Potato is a solanaceous crop and therefore can not be mixed with peppers, eggplants, tobacco, tomatoes and the like
