| 摘 要： | 以吉林省中部玉米带黑土为供试土壤,研究了黑土不同剖面构型的结构特性。结果表明：不同耕作条件下,大于0．25mm水稳性团聚体的含量差异较大。“平面型”犁底层剖面构造有利于改善土壤结构。相关分析表明,大于0．25mm的水稳性团聚体含量与土壤有机质含量及作物产量呈显著相关,相关系数分别为0．860和0．703。 |

| Abstract: | Construction properties of different soil profile constitutions in black soil of corn belt in Jilin were systemically studied.The results showed there are great differences in content of water-stable aggregates(>0.25 mm) under different tillages.The plow pan profile constitution of the "flat type" helps to improve soil structure.Correlative analysis indicated content of soil water-stable aggregates(>0.25 mm) is in high correlation with content of organic matter of soil and yield of corns,and their correlative coefficients are 0.860 and 0.703 respectively. |
| Keywords: | tillage soil construction property aggregate black soil |
