摘　　要：设置黑色液膜、白色液膜、普通地膜、小麦秸秆 4种覆盖物的旱地冬小麦覆盖栽培试验 ,研究覆盖对土壤环境及小麦产量因素的影响。结果表明 ,覆盖对土壤环境和小麦产量影响差异明显。与露地对照相比 ,4种覆盖处理除白色液膜外 ,小麦产量差异均达到极显著水平。其中普通地膜和黑色液膜影响最大 ,其次为小麦秸秆 ,白色液膜影响最小。旱地小麦覆盖栽培产量显著提高 ,是由于覆盖可以提高土层温度和土壤含水量 ,提高水分生产效率 ;改善土壤物理环境和促进小麦生产发育 ;Effect of mulching on soil environment and yield factors of wheat were studied by using experiments with black liquid film, plastic film, white liquid film and haulm. The results indicated that its effects were significantly different from CK excepting white liquid film. The effect of the plastic film on yield factors was the largest in these films, and the black liquid film and haulm was the second and the third respectively, while the white liquid film was the smallest. Film mulching could increase temperature and soil, moisture increase the efficiency of water and productivity speed up the grouting of wheat during the peak time (May 12~27) and photosynthesis of efficacy leaf.
