深松保护耕作法试验结果表明，选用以深松耕作和在深松基础上的夏闲期残茬覆盖，均可提高土壤保墒蓄水效果，以深松覆盖效果最佳，其中２０～５０ｃｍ土层保墒３．５５～１５．７２ｍｍ，０～２００ｃｍ蓄水１８．４ｍｍ，两年小麦平均增产２６．０％。主要原因是麦苗长势强壮，生物学产量等指标增幅较大，尤以稳重增加最高，产量显著高于机翻法。深松深度以３０ｃｍ为宜，辅之以残茬覆盖，蓄水保墒性能更好。
The results showed that the effect of soil moisture storage and storage was improved by using deep-plowing and subsoiling stubble covering on the basis of subsoiling, and the effect of subsoiling was best, among which, soil moisture in 20 ~ 50cm soil layer 3.55 ~ 15.72mm, 0 ~ 200cm water 18.4mm, two years wheat average yield 26.0%. The main reason is the strong growth of wheat seedlings, biological yield and other indicators increased significantly, especially in the highest steady increase, the output was significantly higher than the machine turned law. Deep pine depth of 30cm is appropriate, supplemented by stubble coverage, storage water and soil moisture better.
