一、选地整地马铃薯是不耐连作的作物。种植马铃薯的地块要选择三年内没有种过马铃薯和其它茄科作物的地块。马铃薯对连作反应很敏感,生产上一定要避免连作。如果一块地上连续种植马铃薯,不但引起病害严重,如青枯病等,而且引起土壤养分失调,特别是某些微量元素,使马铃薯生长不良,植株矮小,产量低,品质差。马铃薯与玉米、小麦等植物轮作增产效果较好。二、品种选择根据本地区生态特点和不同用途及市场需求,必须选用经过审定的高产、抗病、质佳的2代以内的标准脱毒种薯。
First, the election site preparation Potato is impotence crops. Potato land plots have to be plots that have not been planted with potatoes and other solanaceous crops for three years. Potato reaction is very sensitive to the production, production must avoid continuous cropping. If a piece of potato is continuously planted on the ground, it will not only cause serious diseases such as bacterial wilt, but also lead to soil nutrient imbalance, especially some trace elements, causing poor growth of potatoes, short plants, low yield and poor quality. Potato and corn, wheat and other plant rotation yield better. Second, the choice of species According to the ecological characteristics of the region and the different uses and market demand, we must use the approved high-yield, disease resistance, good quality within 2 generations of standard virus-free seed.
