摘要:
根据长期田间试验，对施肥、作物、种植方式等对土壤细菌、真菌与放线菌含量的影响进行分析。结果显示：施肥，特别是施有机肥明显提高土壤微生物数量，玉米、苜蓿与冬小麦连作不同施肥土壤细菌数量相对休闲地变幅在-197.04×105～+187.07×105个/g土，真菌在-6.08×103～+36.57×103个/g土，放线菌在-47.21×104～+301.4×104个/g土。轮作系统不同施肥处理真菌与放线菌数量高于休闲地。在施氮磷化肥条件下不同作物轮作，苜蓿与糜子对细菌有相对抑制作用，对真菌与放线菌有促进作用，红豆草抑制放线菌促进细菌，豌豆对三类微生物均有抑制作用。
Abstract:
The fertilization, crop types and planting ways that affected amount of soil microflora were studied according to the data of a long term experiment.The results show that amount of soil microflora increased by original manure application;soil microflora was affected by fertilizers when maize, alfalfa and winter wheat were been planting continuously and the amount of fungi and actinomycetes of rotation and fertilization was more than that of fallow.Effects of broomcorn millet, alfalfa, sainfoin and pea on microflora were different.
