R.DE,Y.YRAO.M.IKRAMULLAH和L.G.GIRIRAO用秸秆覆盖措施(bt/ha)提高玉米产量,秸秆覆盖与一种蒸腾抑制剂相结合处理的试验区灌溉两次或四次,其产量与灌溉四次或六次处理区相同。秸秆覆盖、抗蒸腾措施使玉米穗长度、粒数及粒重得到增加。灌水的利用率因控制了蒸发而增长。 玉米在印度半岛是一种主要的旱季作物,但要得到好的产量,必须灌溉。含水量很小、结构粗糙的土壤更应如此。在半干旱地区,覆盖处理已有效地用来保持土壤水分。一些蒸发抑制剂也具有同样作用。富岭的高粱试验得出用覆盖处理,灌水两次的试验区产量与未处理灌四次水的区产量相同。因此,对粗糙的淋溶土作了一次研究,利用覆盖或蒸腾抑制措施来增强旱地的保水能力。
R.DE, Y.YRAO.M.IKRAMULLAH and LGGIRIRAO Increased maize yield with straw mulching (bt / ha). The test area irrigated with straw mulching and a transpiration inhibitor was irrigated twice or four times and its yield Same as irrigation four or six treatment areas. Straw cover, anti-transpiration measures make ear length, grain number and grain weight increase. The utilization of irrigation increases due to controlled evaporation. Corn is a major dry season crop in the Indian peninsula, but irrigation must be done to get good yields. Soil moisture content is very small, rough structure even more so. In semi-arid areas, cover treatments have been used effectively to maintain soil moisture. Some evaporation inhibitors also have the same effect. Fu Ling’s sorghum trial concluded that the yield in the experimental area that had been twice flooded was the same as that of the untreated IV water. Therefore, a study was conducted on the coarse leached soils, using cover or transpiration suppression measures to enhance the water retention capacity in drylands.
