The results indicated that organic fertilizer at a rate of 75000 kg/ha or organic fertilizer (75000 kg/ha) with compound fertilizer at a rate of 300 kg/ha had higher effects on genetic diversity of soil microbial community under field conditions. Treatment of fertilizers as base application at level of 600 kg/ha resulted in decrease of DNA sequence richness index and diversity index of soil microbial communities, and the similarity coefficient of DNA sequence from soil microbial communities was the lowest compared with control. Organic fertilizer treatment was conducive to increasing DNA sequence diversity index and evenness index of soil microbial communities.
结果表明,在本试验条件下,基肥为75000kg/hm^2有机肥处理和75000kg/hm^2有机肥加300kg/hm^2复合肥处理最好;基肥为600kg/hm^2复合肥处理使土壤微生物群落DNA序列丰富度指数和多样性指数显著下降,与对照的DNA序列相似系数最低;有机肥处理有利于土壤微生物群落DNA序列多样性、均匀度和黄瓜产量的提高。
