【目的】研究增氧对施用有机肥水稻土壤中微生物数量和群落结构的影响。【方法】采用盆栽水稻试验,设计了施用有机肥和增氧2个因素,其中施用有机肥因素设施用绿肥紫云英、施用农家肥干牛粪以及不施肥3个水平,增氧因素设加氧和不加氧2个水平,共计有加氧施用绿肥、不加氧施用绿肥、加氧施用农家肥、不加氧施用农家肥和不加氧且不施肥(对照)5个处理,分别编号为OG、G、OF、F、CK,每处理6个重复。将有机肥与土壤混匀后,称取15 kg放入试验桶中,于水稻苗移栽3 d(返青后)开始进行加氧处理,直至水稻收获后停止。于水稻成熟收割期选取不同土层深度的土壤样品,测定不同处理组微生物数量,并进行磷脂脂肪酸(P...

【Objective】 This study investigated the effects of oxygen on microbial population and community structure in paddy soil with organic fertilizer.【Method】 This study adopted pot experiment of rice with two factors of oxygen and organic fertilizer. Organic fertilizer applications included the use of green manure in milk vetch,farmyard manure in dry cow dung and no fertilizer applied,and oxygen applications included with oxygen and without oxygen. A total of five treatments oxygen with green manure,only with green manure,oxygen with farmyard ma...
