研究了不同施肥方式对红壤水稻土的影响，表明施用无机磷肥最有利于土壤中细

The effects of different fertilization methods on red soil paddy soil were studied, and it was shown that the application of inorganic phosphorus fertilizer was the most beneficial to the growth of bacteria in the soil, and the balanced application of inorganic N, P, and K fertilizers was the most beneficial to the growth of bacteria and actinomycetes in the soil. Bai Zhen et al. (2009) showed that NPK combined with organic fertilizer or straw can significantly increase the number of nitrogen-fixing bacteria, ammoniating bacteria, denitrifying bacteria, nitrifying bacteria, and cellulolytic bacteria in the soil compared with single fertilizer application. Due to the complex and huge number of microorganisms in the soil, 99% of the soil microorganisms cannot be cultivated in the laboratory. With the development of the third generation sequencing technology, more and more high-throughput sequencing technology is used to study the soil microbial community structure

研究了不同施肥方式对红壤水稻土的影响，表明施用无机磷肥最有利于土壤中细菌的生长，平衡施用无机 N、P、K肥最有利于土壤中细菌和放线菌的生长。白震等（2009）明了与单施化肥处理相比，NPK配施有机肥或秸秆,能显著增加土壤中固氮菌、氨化细菌、反硝化细菌、硝化细菌、纤维分解菌数量。由于土壤中微生物繁杂，数量巨大，99%的土壤微生物不能在实验室培养，随着第三代测序技术的发展，对土壤微生物群落结构的研究越来越多的采用高通量测序技术
