摘  要:
为了探讨紫花苜蓿与无芒雀麦混播对松嫩平原盐碱化草地土壤的改良效果,分析比较了混播草地与盐碱化草地的土壤含水量、容重、pH、土壤全盐量和主要养分等的变化。结果表明:紫花苜蓿与无芒雀麦混播可显著降低盐碱化草地土壤0~30cm土层的含水量、容重、pH和全盐含量(P<0.05),4个指标分别比盐碱化草地降低9.88%、14.37%、10.56%和24.80%;种植紫花苜蓿与无芒雀麦后土壤主要养分均增加,0~30cm土层的有机质、全氮、速效氮、全磷和速效磷分别是盐碱化草地的1.41、1.29、1.09、1.15和1.39倍,种植年限越长增量越多。紫花苜蓿与无芒雀麦混播改良盐碱化土壤效果明显,土壤环境向有利于植物生长的环境方向转化。

摘  要:
In order to discuss the soil improvement effect of alfalfa mixed with smooth brome grass on saline-alkaline grassland in Songnen Plain,change of water content,soil bulk density,pH,soil salt content and main soil nutrition of alfalfa and brome grass mixture grassland and saline-alkaline grassland were analyzed.The results showed that alfalfa and smooth brome grass mixture grassland could reduce water content,soil bulk density,pH and soil salt content of 0~30 cm layer significantly(P<0.05),the reduce rates were 9.88%,14.37%,10.56% and 24.80%,respectively compared with saline-alkaline grassland.The main soil nutrition increased by planting alfalfa and smooth brome grass.Soil organic matter,total nitrogen,available nitrogen,total phosphorus and available phosphorus were 1.41,1.29,1.09,1.15 and 1.39 times higher than those of saline-alkaline grassland.Alfalfa and smooth brome grass mixture grassland had a visible improvement effect to the saline-alkaline grassland soil,the soil condition turned to propitious growth.
