优化施肥对设施土壤微生物生物量碳氮的影响
Effects of Optimized Fertilization on Microbial Biomass C,N of Greenhouse Soil
摘要
Abstract
In order to improve soil quality and optimize soil microflora ,the effects of optimized fertilization on microbial biomass carbon ,nitrogen contents of greenhouse soil were studied by methods of field plot experi-ments and indoor test analysis .The results showed that the contents of soil microbial biomass carbon (MB-C) and soil microbial biomass nitrogen(MB-N)were firstly increased and then decreased .The peak value of MB-C appeared earlier than that of MB-N .Compared with no nitrogen treatment and farmer practice fertilization treatment ,MB-C and MB-N could be increased by the treatments of optimized fertilization plus potassium hu-mate or optimized fertilization plus zeolite .For the treatment of optimized fertilization plus zeolite ,rates of MB-C and MB-N in organic carbon and total nitrogen were the highest and higher than no nitrogen treatment 41 .2% and 61 .9% respectively ,higher than farmer practice fertilization treatment 9 .1% and 21 .4% respec-tively .The rate was higher in the treatment of optimized fertilization plus potassium humate and zeolite ,higher than no nitrogen treatment 41 .2% and 38 .1% respectively ,higher than farmer practice fertilization treatment 9 .1% and 3 .6% respectively .According to this study ,we concluded that greenhouse soil quality could be im-proved by optimized fertilization plus potassium humate or zeolite .关键词
