不同膜色覆膜对马铃薯生育、产量及淀粉含量的影响

Effects of Different Color of Plastic Mulching Methods on Grouth, Ttuber Yield and Starch Content of Potato

在南疆干旱区以极早熟品种东农303为试验材料,设置了覆黑膜、白膜、不覆膜三种处理。分别对植株株高、茎粗、主茎数、侧枝数等植株性状,土壤含水量、土壤温度、单位面积杂草数等田间环境,及产量性状进行调查测定分析,结果表明:黑膜处理保墒效果好、可适当增温,抑制杂草生长改善田间作物生长环境,使株高、主茎数显著增加,显著提高了总产量、商品薯产量和淀粉产量。

With potato variety Dongnong303 as tested material in South Xinjiang, we studied plant traits such as plant height ,the number of main stem, the number of lateral branch, the field environmental factor such as soil water content, soil temperature and the number of weeds, and yield traits. The result shows that the moisture and temperature condition of soil could be improved, number of weeds per square meter was reduced, and the tuber yield and starch content of potato could be increased effectively when the method of black film was taken.
