摘要
研究测试鸡粪有机无机复混肥对大豆根际微生物区系及幼苗生长的影响。结果表明:施用鸡粪有机无机复混肥后大豆根际真菌、细菌和放线菌种群在大豆生育期内的动态变化规律与化肥和未施肥对照基本一致。鸡粪有机无机复混肥当使用剂量为150 kg.hm-2时对大豆根际土壤中的真菌、细菌和放线菌的影响与化肥使用剂量225 kg.hm-2整体差异不显著,并可增加大豆的根瘤数、株高,降低根腐病发病程度,同时该剂量也可降低成本。
This study is to analyse the effects of different dosage of organic and inorganic compound fertilizer（OAICF）on soybean rizosphere microorganism population and soybean seedling growth.Three dosages of OAICF were tested in the field experiment.The population dynamic changes of soybean rizosphere fungi,bacteria and actinomycetes had no significant difference,when soybean was fertilized by OAICF compared with chemical fertilizer and none fertilizer.In the soybean seedlings,the difference of soybean rizosphere fungi number was not signifcant between the treatment of OAICF and two CK.In the blooming,the rizosphere fungi number of soybean treated by OAICF in 150 kg·ha^-1and 300 kg·ha^-1 comparing with chemical fertilizers in 225 kg·ha^-1 was not different significantly,but was lower significantly than the treatment of CK.In the other periods,the difference of the fungi number of soybean rizosphere treated by different fertilizers was not significant.The rizosphere bacteria number of soybean treated by OAICF in was 225 kg·ha-1 the highest in blooming,the pod bearing period and maturity.However the usage of 150 kg·ha^-1 was not different significantly than two CK.The difference of the rizosphere actinomycetes number of soybean treated by OAICF was not significant than two CK in soybean growth.The experiments were founded that the soybean fertilized by 150 kg·ha^-1 OAICF resulted in the increase in root nodules and plant heights of soybean,however reductions in soybean root rot disease.The cost of 150 kg ·ha^-1 usage was also relatively low.
