对于马铃薯栽培,土壤耕作的主要任务就是创造满足马铃薯生物学上需要的土壤环境条件。葡萄茎及其所形成的新块茎,具有大而疏松的细胞结构,在生长过程中,紧密土壤微粒的机械阻力,往往会使生在板结土壤中的马铃薯根系发育不良(1973)。很显然,土壤容重的变化会引起马铃薯生长及其产量的变化。借助于耕翻和中耕就可造成最 For potato cultivation, the main task of soil cultivation is to create a soil environment that meets the biological needs of the potato. The grape stems and their new tubers have a large, loose cell structure. The mechanical resistance of the compact soil particles during growth tends to underdevelop the root system of potato plants in the compacted soil (1973). Clearly, changes in soil bulk density can cause changes in potato growth and its yield. With plowing and cultivating can cause most
