摘　　要：采用随机区组试验设计,研究绿肥对土壤肥力的影响。结果表明:绿肥在黄壤上连施和混施能使土壤养分逐年增加,特别是3种绿肥(豆科绿肥、禾本科绿肥和十字花科绿肥)的混施,能显著提高土壤养分含量。With the method of randomized block design,the influence of green manure on soil fertility was analyzed. The results showed that, the soil nutrient increased year by year by consecutive and mixed fertilization,especially the mixed application of three green manures （lequminous green manure, gramineous green manure and cruciferous green manure）, which can improve the content of soil nutrients obviously.
