针对大部分油茶林产投比不高的问题,利用从油茶根际土壤中分离纯化出的高效固氮、解磷、解钾菌（YC-NK03、YC-NK04、YC-NK05、YC-NK07、YC-P05、YC-P06）制成菌糠菌肥与化学肥料混合施用,探究生物复合肥对油茶和土壤微生态的影响以及菌肥、化肥最佳配比。盆栽结果显示,T3组（60%菌糠菌肥+40%化学肥料）对油茶的促生效果和微生态变化显著。与施用前相比,T3组的苗高、地径增加了108.64%、45.62%,土壤微生物总量、土壤有机质、水解N、有效P、速效K含量分别增加了70.41%、83.26%、101.55%、118.44%、18.63%。林间试验结果表明,肥料种类与用量对土壤pH无显著影响;虽然各试验组的树高和地径均有不同程...

In order to solve the problem of low yield and high input of most Camellia oleifera plantations,the high-efficiency nitrogen fixing bacteria,potassium bacteria and phosphorus dissolving bacteria( YC-NK03,YC-NK04,YC-NK05, YC-NK07,YC-P05,YC-P06)were isolated and purified from the rhizosphere soil of Camellia oleifera and were used as bacterial fertilizer and mixed with chemical fertilizer,and the effect of bio-compound fertilizer on Camellia oleifera and soil microecology and the optimal ratio were explored.The results of pot experiment showed th...
