摘要
采用定位研究的方法,在洛阳典型的丘陵坡耕旱地上,经过8年的连续研究表明:深松覆盖与免耕覆盖技术能显著提高土壤对降水的贮蓄能力,最高可较对照增加20%以上;深松覆盖较免耕覆盖的增产作用更为显著,两者在试验3年以后均表现出提高降水利用效率的作用。
Eight years continuous orientation researches on typical upland dry land in Luoyang indicated that SB-cover and NT-cover techniques could significantly increase soil capability to rainfall, and the highest increasing extent was over 20 percentage compared to CK. The yield increasing effect of SB-cover treatment was better than that of NT-cover treatment. Compared to CK, both SB-cover and NT-cover could heighten rainfall use efficiency only after 3 years from beginning of this expriment.
