通辽市科尔沁区耕地土壤有机质含量分布现状
Distribution of Soil Organic Content in Horqin Cultivated Land
摘要
Abstract
Based on the data collected in 1983,the distribution of soil organic content of ten towns and villages in Horqin District,Tongliao City,Inner Mongolia was determined,and the evolution laws of the local soil organic matter and the way to increase the soil organic content were analyzed There was great variability in the soil organic content in the cultivated.The maximum soil organic content was 2 to 5.3 times as much as the minimum. There was no signifi-cant difference of average organic content in the cultivated land in different areas. Increasing organic fertilizer,re-turning crop stalks to the field and no-tillage technology are effective ways to increase the soil organic content.关键词
