摘　　要：为了指导大豆生产实践,采用大区对比方法,设置6种中耕措施,研究了不同中耕措施对田土壤温度、含水量及大豆产量的影响。结果表明:25cm深松处理可有效提高耕层土壤温度和含水量,并促进大豆生长和提高产量,25cm深松与耱地结合的促进效果更好;10cm深松和耱地处理对土壤温度、含水量和大豆产量无明显促进作用;苗期3次培垄处理仅在一定程度上提高5cm耕层土壤温度,对大豆生长和产量无明显促进作用。综合分析认为,适当深度的深松处理可提高垄体温度和水分含量,促进大豆生长和产量提高,深松与耱地相结合效果更好。In order to guide the production practice, in huge area contrast experiment, 6 intertillage treatments were set to study the effect of intertillage on soil temperature and water content and soybean yield. The results showed that 25 cm subsoiling tillage could increase soil temperature and water content,and promote the growth and yield of soybean,and effect was better with smoothing. 10 cm subsoiling tillage had no effect on soil temperature and water content and soybean yield. Ridge hilling with 3 times could increase the temperature of 5 cm soil layer to some extent,but could not promote the growth and yield of soybean. In conclusion,subsoiling tillage with proper depth could increase soil temperature and water content,and promote the growth and yield of soybean,and effect was better with smoothing.
