摘  要：
为了解决辽宁省西北地区春播时期干旱缺水导致墒情不够无法播种和出苗难的问题,在长期田间种植试验和调研的基础上,研制了1HS-2型中耕深松机。对深松机进行了田间性能试验,结果表明,该机结构合理,深松深度等性能指标符合农艺要求。2005和2006年,分别应用研制的中耕深松机在辽宁省阜新地区进行中耕深松试验,深松深度为20～25cm。在玉米收获期对深松后的土壤和未深松土壤的物理性质进行测试分析,测试结果证明:深松与未深松(CK)相比,耕层土壤含水量显著增加,土壤容重显著降低。

摘  要：
1HS-2 subsoiler was developed based on long term field planting experiment and investment to solve the problem of the maize planting in north-west area of Liaoning province,where the maize can not be sowed or the seed is difficult to sprout during the period of sowing in spring because of the inefficient water content in soil.Field performance test showed the structure of the subsoiler was reasonable and the performance index such as subsoiling depth fit agricultural requirements.Deep tillage was carried out during the period of maize seedlings using 1HS-2 subsoiler in Fuxin area of Liaoning province in 2005 and 2006.The soil was tilled to 20~25cm depth.The test and analysis on soil physical properties of deep tilled and no tilled soil during harvest period showed the soil water content increased and the bulk density decreased significantly compared to CK.
