马铃薯高垄双行整薯覆膜栽培技术研究

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。

Potato Production Technique in Two-row Mulching Culture on High-ridge with Small Whole Tubers Seeding

The growth and yield performances of potato under plain fertile field and slope field were studied in relation to the ridge types,row pacing,and planting densities.The results indicated that planting arrangement styles did not affect potato growth and development evidently,suggesting that suitable style can be chosen for the convenience of farming practice.Higher planting density is more likely adapted to the slope field.Whole potato tuber seeding is a key for enhancing the growth and increasing potato yield,with a yield increase more than 16% and 20% in plain fertile field and slope field,respectively.
