摘  要：
针对临夏州旱作农业区水资源不足、降水季节分布不均、玉米播种期春旱严重等问题,开展了旱地玉米半覆膜地、全膜双垄地(秋覆膜、顶凌覆膜、播前覆膜)0~50 cm土壤水分变化的试验,结果表明:秋覆膜优于顶凌覆膜、播前全覆膜和半覆膜。因此,秋覆膜、顶凌覆膜双垄沟播技术是干旱区充分利用秋、冬季降水资源解决春旱难题的有效途径,更是旱地玉米稳产高产的有力保障。

摘  要：
Aiming at the problems of water resources shortage,uneven seasonal distribution of rainfall,and severe spring drought at maize sowing stage in dry farming region of Linxia state in Gansu province,the author carried out the tests for the changes in 0 ~ 50-cm-deep soil moisture in maize dryland which was half covered or fully covered with film. The results showed that the autumn full mulching was superior to the top full mulching,the pre-sowing full mulching,and the half mulching. Thus,the technique of double-furrow sowing with autumn full mulching or top full mulching was an effective approach to sufficiently utilize autumn and winter rainfall resources to solve the spring drought problems in dry farming region,and also was the powerful guarantee for the stable and high yield of spring maize in dryland.
