功能微生物对花生根际土壤生物学肥力和养分利用的影响
Effect of functional microorganism on rhizosphere soil biological fertility and nutrient utilization
摘要
Abstract
To alleviate soil obstacles caused by continuous peanut cropping and to improve peanut yield and quality,impacts of functional microorganisms were investigated on biological fertility and nutrient utilization in pea-nut rhizosphere soil in vertisol soil area.Effects of 3 fungi(Trichoderma harcii,Paecilomyces lilacinus,Aspergillus oryzae)and 2 bacteria(Bacillus subtilis,Bacillus licheniformis)were studied on microbial content,enzyme activity,microbial carbon,microbial nitrogen,microbial phosphorus in rhizosphere soil,nutrient in peanut kernel,agronomic characteristics and peanut pod yield by field experiment randomized block design.Results showed that,functional microorganism could increase quantity of fungi and bacteria,decrease quantity of actinomycetes;increase quantity of microbial biomass carbon,microbial biomass nitrogen and microbial biomass phosphorus;increase activities of catalase,phosphatase,urease,protease and sucrase in rhizosphere soil;increase content of N,P,K and Zn in peanut kernel;increase main stem height,lateral branch length,lateral branch amount,full pod amount;reduce the number of no full pod.Pod yield of peanut increased by 252.5-480.4 kg/hm2,resulting in a 5.1%-9.6%increase in produc-tion.Compared with applied bacterial fertilizer,application of fungi increased pod yield by 153.9 kg/hm2 on aver-age,resulting in a 3.0%increase in production.With the application of 120 kg/hm2 N,90 kg/hm2 P2O5,and 120 kg/hm2 K2O as a base,applying functional microorganisms at a rate of 75 kg/hm2,the average yield of peanut pods in-creased by 349.6 kg/hm2,with a yield increase rate of 7.0%.Moreover,pod yield reached its highest at 5464.2 kg/hm2 at Trichoderma harzianum application of 75 kg/hm2,which should be recommended in the main producing ar-eas for summer peanut.关键词
