摘要
通过对草坪土壤施加不同剂量的土壤改良剂,采用实验室平板涂抹记数法,观测不同处理下土壤微生物数量的变化,对土壤改良剂的施用效果做出评价。结果表明:根际细菌数量与土壤改良剂剂量呈正相关,随着土壤改良剂剂量的增加根际细菌数量呈上升趋势;根际放线菌数量随土壤改良剂剂量的增加呈先下降后上升的趋势;根际真菌数量与土壤改良剂剂量呈负相关,随着剂量的增加,根际真菌的数量逐渐减少。
Different amounts of the soil conditioner applied to Kentucky bluegrass soil, the number of soil microbes was observed by introduced flat counting process and the effect of different soil conditioner treatments was evaluated. The main results showed that the quantity of microbes presented positive correlation with soil nutrients and the quantity showed increase with the amount increase of soil condition while the quantity of rhizosphere fungi presented negative correlation with soil condition and it increased gradually with decrease of the soil condition.
