摘 要:在我国东北的半干旱地区,由于春旱造成的土壤墒情不足,严重影响着大田作物的发芽和出苗。进而严重地影响着作物的生长发育和产量。坐水种是一种较好的抗旱播种方法,苗期补灌技术也是一种旱地农业生产措施,垄作区田不仅是一项水土保持措施,而且也能改善土壤的水分环境,促使作物增产。在田间试验基础上,对有限的坐水、补水和垄作区田的技术集成对东北半干旱地区玉米产量的影响进行了研究,并予以了定量的描述,以求为东北半干旱地区玉米的节水栽培提供出一套可调控的定量化组合方案。Because of the drought in spring lead to the lack of soil water, which influent sprout and emerging of crops gravely, furthermore, which affect growing and yield of crops. Storage water under the seed is a better way of drought—resistance in the time of planting, supplement water in seeding period technique also is a way of agriculture produce in dry land. ridge plotted field not only is a way of preserving water and soil, but also perfect soil-water environment and improve the yield of crops. This article is on the basis of field experiment, study on the effect that limited water supply and ridge plotted field technique act on the yield of maize and give quantitative analysis, aim to supply a assembler program for maize cultivate about economize on water in semi-dry land in northeast area.
