一、整地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。马铃薯块茎播种后产生的根系为须根系,穿透能力较差。土壤疏松有利于根系的生长发育,有强大的根系,可以增强吸收土壤中水分、养分的能力,源源不断输入地上部分,使植株生长健壮,光合能力增强,光合产物增多,为高产提供物质基础。因此,深耕是马铃薯高产的基础。
First, soil preparation Deep plowing can make the soil loose, improve water storage, water retention capacity, coordinate the soil water, fertilizer, gas and heat fertility factors for the growth of potato roots and stolons, tubers to provide a comfortable environment for growth. Potato tubers produce roots after sowing root system, penetration is poor. Soil loose is conducive to the growth and development of the root system, a strong root system, can enhance the ability to absorb water and nutrients in the soil, a steady stream of input to the aboveground, so that plants grow robust, photosynthetic capacity increased photosynthetic products, providing the material basis for high yield. Therefore, deep plowing is the basis of high yield of potato.
