　　设计并研制了小型深松机，在收获后秸秆还田的基础上进行了深松试验。结果表明，深松可以显著地减小地表不平度，播种质量有显著提高，对于促进保护性耕作技术发展具有积极的作用。通过深松使土壤容重下降，增大了土壤渗水率和含水量，对春天干旱区域来说有利于吸纳雨雪并缓解干旱。

The small subsoiler was design and development , and ,the subsoiling experiment has been done on the basis of straw after harvest ,the experiment results show that subsoiling can significantly reduce the surface roughness and improve planting quality , give full play to the yield potential of conservation tillage technology has a positive role , subsoiling can reduce soil bulk density , and the seepage rate of the soil , increase soil moisture , and severe spring drought in the re-gion, by subsoiling after the autumn harvest , can effectively save and absorb the snow to ease the spring drought , which will play a very good role .
