马铃薯覆膜双垄集雨沟播技术效益研究

A Study of Benefit of Mulching Double Ridges Rainwater Gathering Furrow Sowing Technology for Potato

在低温阴湿区代表性区域宁夏泾源县进行的马铃薯覆膜技术效益试验结果表明:全膜覆盖栽培的增产增收效果优于半膜覆盖栽培,且增温保湿效果较明显;覆膜时期以秋季最佳,其次是早春覆膜,而播期覆膜的效果最差。

The results of a test on the benefit of mulching technology for potato conducted in Jingyuan county,a representative district of the low temperature and damp area in Ningxia showed that the yield and benefit increase effects of the mulching cultivation were better than those of the half-mulching cultivation and the temperature-increasing and moisture-keeping effects were obvious.The best time for mulching was during Autumn and the secondary was during early Spring and the effect was worst when mulching was conducted during sowing time.
