| 摘 要： | 以落叶松人工纯林及落叶松与大豆混农间作人工林下土壤为研究对象,对不同林分下土壤物理性质和化学性质进行测定及比较分析,结果表明:混农林的土壤容重低于纯林,土壤总孔隙度和含水量大于纯林。另外,落叶松与大豆间作使土壤有机质含量增加,全N、速效N、P、K的含量增加,其中间作林土壤中N素含量增加尤为明显。 |

| Abstract: | Taking pure forest of larch and soil under argosoybean intercropping plantation as subjects,soil physical and chemical properties under different stand were determined and analyzed.The results show that the soil bulk density of agroforestry is lower than that of the pure forest.The total porosity and moisture content of agroforestry are bigger than that of the pure forest.The larch and soybean intercropping make the increment of soil organic matter,total N,available N,available P,and available K.Soil nitrogen content increases significantly among others. |
| Keywords: | larch agro intercropping soil |
