摘要
在半湿润偏旱的豫西丘陵区坡耕地上 ,进行了夏季休闲期间不同耕作方式的试验研究 ,观测其对降水的保蓄能力与减少地表径流之效果。结果表明 ,不同耕作方式之间差异明显 :免耕和深松处理比对照 (一般耕作 )的保蓄能力分别提高 5 .6 7和 6 .11个百分点 ,径流量减少 0 .4 3mm和0 .71mm ;单纯深翻的处理两种作用均低于对照。而以种植作物的防径流效果最佳 ,比对照少 2 .33mm ,比免耕、深松也减少 1.87mm与 1.5 9mm ,比深翻耕作减少 4 .0 7mm。
The experiments on the different tillage practices in the slop field during summer fellow were conducted in the semi-humid rainfed areas of the western of Henan province. Compared with the conventional tillage, the soil storage capacity for rainfall by non-tillage and by subsoiling was increased by 5.67% and 6.11% respectively, and the rainfall runoff reduced by 0.43 mm and by 0.71 mm respectively. By deep ploughing the soil storage capacity for rainfall was lower and the rainfall runoff was higher than the conventional tillage. By Cropping during summer the rainfall runoff could be minimized, in which the rainfall runoff reduced by 4.07 mm than the deep ploughing, by 2.33 mm than the conventional tillage, by 1.87 mm than the non-tillage, and by 1.59 mm than the subsoiling respectively.
