| 摘 要： | 针对山西旱作农业区年降水量少、季节分布不均,特别是玉米生产中春旱严重等问题,在山西忻州进行了旱地玉米不同覆盖方式试验。结果表明,顶凌全地膜覆盖的产量最高,为11 926 kg/hm2,比对照增产4 426 kg/hm2,二者差异达到极显著水平。顶凌全地膜覆盖双垄沟播技术可有效利用冬春降雨,解决春旱难题,是解决山西省旱地玉米高产稳产的有效方法。

| Abstract: | To meet the water requirement for maize growth under the situation of limited and unevenly distributed rainfall,especially the existing problem of serious spring drought in dry farming area in Shanxi,effect of various yield-increasing film mulching modes for dry land maize was studied.The result showed that the mode of ditch sowing in double ridge mulched with plastic films in ice crust was the most effective for dry land maize.The maize yield was 11 926 kg/hm2 and it increased 4 426 kg/hm2 than the control... |
