文章针对风沙土耕作区气温低,天然降水少等不利因素下,玉米的水分生态效益问题,进行了垄向区田、行间覆膜、秸秆覆盖和垄向区田与行间覆膜的集成措施四种保护性耕作措施研究。试验表明各保护性耕作措施对玉米水分生态效益影响较大,其中行间覆膜与垄向区田集成措施和行间覆膜措施的玉米长势最好,在整个生育期内其叶面积指数、株高、茎粗、产量等方面均极显著或显著优于对照处理,各措施对玉米生长影响的优劣程度依次为:垄向区田与行间覆膜的集成措施>行间覆膜>垄向区田>对照>秸秆覆盖。
In order to solve the problem of water eco-efficiency of maize under the unfavorable factors of low temperature and natural precipitation in wind-blown soil farming area, the paper studied the integration of ridge fields, intercropping mulching, Study on four measures of conservation tillage. The results showed that all the conservation tillage measures had a great impact on the ecological efficiency of corn water. The corn with intercropping and ridge-field planting measures and the intercropping measures had the best growing tendency. During the whole growth period, the leaf area index, Plant height, stem diameter, yield and other aspects were significantly or significantly better than the control treatment, the measures of maize growth are: the integrated measures of ridge field and intercropping> Interline> Ridge area> control> straw cover.
