摘要
在宁夏西吉县黄土丘陵缓坡地上进行不同膜色与不同覆膜方式旱地马铃薯不同品种间的水分、温度、经济效益等研究,结果表明:蓄水保墒能力,膜色的影响不大,主要取决于覆膜方式;平抑地温变化方面,黑色膜比白色膜作用强,适应马铃薯栽培。3因素中品种对马铃薯产量的影响最明显,其次是覆膜方式,膜色影响较小。为获得高产,推荐首选组合是黑色全膜×庄薯3号,其次是白色全膜×庄薯3号,再次是黑色半膜×庄薯3号与白色半膜×庄薯3号。
A study on water efficiency,temperature effect and economic benefits of different varieties of dry land potatoes with different plastic mulching methods and different film color was made on loess hilly ground slope in Xiji County.The results show that： the effect of film color on moisture storage capacity is not big,depending mainly on mulching methods;But in bringing down the ground temperature change the black film had a stronger effect compared with that of white film and adapting to the potato cultivation.Among three factors,the effect of different varieties on the potato yields is largest,followed by mulching methods,the effect of film color was relatively smaller.For the high-yield preferred combinations it is recommended that black film×zhuang potato 3 is the first choice,followed by the white film×zhuang potato 3,the third is black half-film×zhuang potato 3 and white half-film×zhuang potato 3.（the ＂×＂ is interaction meaning）.
