为了探究深旋松耕提升马铃薯产量与质量的可行性。在山东省胶河地区以常规旋耕为对照,研究深旋松耕对土壤物理性质、马铃薯根系及产量形成的影响。结果表明:与常规旋耕相比,深旋松耕能打破犁底层,显著降低20~40 cm土层的容重和穿透阻力,提高0~50 cm土层的贮水量25.67%,促进作物生长,其中马铃薯根系生物量显著提高26.61%,中、下层叶片净光合速率分别增加20.82%、37.13%,进而提高花后光合产物积累量,促进花后干物质向块茎的转运,使得单块薯重量提高29.82%,马铃薯增产38.68%。 In order to explore the feasibility of improving the yield and quality of potato with deep furrow loosening. In the Jiahe area of ​​Shandong Province, the conventional rotary tillage was compared to study the effects of deep-tillage pine on the soil physical properties, potato root formation and yield formation. The results showed that deep loosening plowing reduced the plow floor and significantly reduced the bulk density and penetration resistance of 20-40 cm soil layer compared with that of conventional rotary tillage, and increased the water storage capacity of 25-50 cm soil layer by 25.67% , In which the potato root biomass increased significantly by 26.61%, the net photosynthetic rate of middle and lower leaves increased by 20.82% and 37.13%, respectively, and then increased the accumulation of anthesis photosynthate and post-anthesis dry matter to tubers, Increase 29.82%, the yield of potato increases 38.68%.
