1 播前整地马铃薯是以地下块茎为收获产品,为促进高产,就要为块茎在地下生长创造良好的土壤环境。深耕可以使土壤疏松,提高蓄水、保水能力,协调土壤中水、肥、气、热肥力因素,为马铃薯根系和匍匐茎、块茎的生长提供舒适的生长环境,因此,深耕是马铃薯高产的基础。据研究耕深15～18cm 时,松土层达30cm,较浅耕的增产10%。耕深达到36cm 的地块,比耕深18cm的可增产63.1%,可见整好地是马铃薯高产的前提。2 选地、选茬马铃薯选茬时一定要注意,前作避免和茄科作物的辣椒、西红柿、茄子等作物重茬,以免同源病虫害
1 before sowing potato is based on underground tubers for the harvest products, in order to promote high yield, it is necessary to tubers in the underground to create a good soil environment. Deep plowing can make the soil loose, improve the ability of water storage and water retention, and coordinate the factors of water, fertilizer, gas and heat in the soil to provide a comfortable environment for the growth of potato roots and stolons and tubers. Therefore, deep plowing is the basis of high yield of potatoes. According to the study of tillage 15 ~ 18cm, loose soil up to 30cm, 10% more than the shallow tillage. Plowing depth of 36cm of land, yielding 63.1% more than the tillage 18cm, shows that good is the premise of high-yield potato. 2 election, when selecting stubble, it must be noted that before crop and crop of Solanaceae pepper, tomato, eggplant and other crops cropping, in order to avoid the same pests and diseases
