在平肥地与坡地条件下对不同垄形、株穴距、密度马铃薯生长发育和产量表现进行了研究。研究结果表明,植株田间配置方式对马铃薯生长发育没有显著影响,可选择便于农事操作的配置方式。坡地比平肥地更适宜较高的种植密度。整薯做种薯栽培是马铃薯高产的关键措施,在平肥地上可提高块茎产量16%以上,坡地上提高20%以上。
The growth and yield of potatoes with different ridge shapes, plantar spacing and density were studied under the condition of plain and sloping land. The results showed that the field configuration of plants had no significant effect on potato growth and development, and the configuration of agricultural operations could be selected. Sloping land is more suitable than high-density planting density. Whole potato as seed potato cultivation is the key measure for high yield of potato. It can increase the yield of tubers by more than 16% and increase more than 20% on the slope in the flat fertilizer field.
