| 摘 要： | 以玉米连作为对照 ,研究了草田轮作对岗平地黑土的生态效应。结果表明 :在水蚀和风蚀严重的岗平地黑土上实行草田轮作 ,有利于改善土壤的孔隙状况 ,从而改善岗平地黑土的通气有余、持水不足、易于干旱和沙化的状况。草田轮作可以增加土壤微生物的数量 ,增强微生物的总体活性 ,也可以增加土壤的酶活性 ,进而提高土壤的生物活性 ,改善土壤的环境条件。

The Ecological Effect of Grass and Crop Rotation on Ridge Chernozem |
| |
| Abstract: | This thesis studied ecological effect of high ridge chernozem by control test of corn continuous cropping.The result indicated that grass and crop rotation improves aperture condition of soil,to improve the condition of much air draft and drought and sand,because of abstract ability of keeping water on the chernozem of bad water erosion and wind erosion.Grass and crop rotation could increase the quantity of soil microorganism,intensify its activation,improve soil enzyme activity,enhance biological activity of soil and establish better soil environment condition. |
