| 摘 要： | 固定宽垄沟灌保护性耕作是将保护性耕作、固定道、垄作和沟灌等相结合的一项农业技术,该技术可通过松垄作业解决宽垄水分侧渗效果差的问题.从2005年开始,在西北灌区对固定宽垄沟灌保护性耕作条件下的松垄效应进行了系统的试验研究.试验结果表明,在0～100 cm深度范围内,松垄作业能促进水分向宽垄中央渗透,增强土壤的通透性,提高8%左右土壤含水量,并能增加2%左右作物产量.建议在采用固定宽垄沟灌保护性耕作技术的地区推广松垄技术.

| Abstract: | Permanent Raised Beds(PRB),which is an agricultural technology with the features of conservation tillage,controlled traffic,ridge-tillage and furrow irrigation,can adopt ridge-loosing technique to solve the problem of weak water infiltration ability of wide ridge.This paper has conducted a systemic research of ridge-loosing technique under PRB since 2005.The experimental results showed that in the depth of 0~100 cm,ridge-loosing could accelerate water infiltration from the furrow to the center of wide ridge,intensify the permeability of soil and increase soil water content at 8%.What is more,it can also enhance crop yield at 2%.It is recommended that the ridge-loosing technique should be spread in the areas where PRB is adapted. |
