| 摘 要： | １９９６年１０月至１９９８年９月，在宁南旱作农业区，采用沟垄相间、垄上覆膜、沟内种植、垄面产流、沟内集水的微集水种植方式进行试验。结果表明，玉米耗水量增加９９．６％～１００．５％，产量提高６７．９％～７１．０％，水分利用率达到１３．８４～２１．７６ｋｇ／（ｍｍ·ｈｍ２）；处理中窄垄型增产效果优于宽垄型。

| Abstract: | The planting technique of microwater harvesting includes two parts:water harvesting area and planting area.The water harvesting area is a ridge mulched with plastic film and even small rain can easily run down planting area,so soil moisture in planting area can be improved greatly.This technique has been developed in dryland of south part of Ningxia in order to improve capability of soil water supplying,decrease water stress and increase WUE in planting area.The results of experiments from 1997 to 1998 show that the water consumption of corn is 99.60.5% and the yield of corn 67.9q.0% compared with CK.And WUE reaches to 13.8421.76 kgmm1hm2.Effect of ridge with 60 cm of width is prior to ridge with 75 cm wide on improving corn yield. |
