摘要
在不同的农业措施下,对大豆播前、苗期、花期和成熟期的土壤木霉菌数量进行测定结果表明,多年连作后大豆田土壤中木霉菌数量有明显减少的趋势,而轮作大豆田土壤中木霉菌数量明显增加;采取秸秆还田、施有机肥和化肥等措施有利于大豆田土壤中木霉菌的繁殖,采用免耕和深松措施比常规耕翻有利于土壤中木霉菌的数量增多。
After different agricultural practices were used in soybean field, the population of Trichoderma in soil were tested in different growth period. The result showed that the population of Trichoderma in soil were obviously decreased after many years of continuous cultivation, while obviously increased in rotation plots. Using organic manures or straw returning or chemical fertilizer could advance the reproduction of Trichoderma in soybean field. Among three methods kf tillage, the population of Trichoderma using no-tillage or deep plough were more than conventional.
