旱作马铃薯不同膜色不同覆膜方式对比试验研究

Comparison Experiment for Different Color of Film and Different Mulching Methods of Dry Land Potato

不同颜色地膜和不同覆膜方式试验研究结果表明:降雨较多的情况下,半膜覆盖产量高于全膜覆盖,黑膜覆盖高于白膜覆盖,几种方式中黑色半膜覆盖产量最高,达到2465.88kg/667m2,比不覆膜增产408.29kg/667m2,增幅19.84%。马铃薯黑色地膜覆盖增产效果显著,可在乌兰察布市半干旱山区及周边类似气候区域大面积推广使用。

The result of the study of plastic films with different color and different ways showed that the amount of maize yield of the half covered was higher than that of the fully covered in case of more rainfall, the amount of maize yield of the black plastic film mulched was higher than white plastic film mulched, and among all the different mulched ways, the amount of the maize yield that was the highest in the field that was mulched with black plastic film half covered, reaching at 2465.88kg/667m2, and at 408.29kg/667m2 higher than that mulched with no plastic film, with an increase of 19.84%.The increase by mulching the filed with black plastic film was significant, and this way could be promoted in large area of semiarid Ulanqab and the surrounding areas with similar climate.
