几种微生物菌肥对连作黄瓜生长及土壤理化性状的影响

通过盆栽方法研究了4种微生物菌肥（连茬王、多功能木霉菌肥、金宝贝和护根宝）对连作黄瓜生长及土壤理化性状的影响。结果表明：4种微生物菌肥均能明显促进连作黄瓜生长，其中护根宝处理的黄瓜株高、叶片数、叶干质量、植株总干质量及叶面积指数分别比对照增加54.8%、40.0%、96.0%、94.9%、73.2%，差异均达显著水平，处理效果最好。除金宝贝外，其余3种微生物菌肥均能显著增加黄瓜叶片总叶绿素及类胡萝卜素含量，以连茬王效果最好，增加幅度分别为34.0%、28.0%。多功能木霉菌肥处理下的黄瓜连作土壤容重显著降低，土壤孔隙度显著提高。4种微生物菌肥均能有效改善黄瓜连作土壤化学性状，多功能木霉菌肥处理下土壤pH值及有机质、碱解氮、有效磷、有效钾含量分别比对照增加4.3%、14.3%、21.5%、14.1%、14.8%，差异均达显著水平。总体来看，4种微生物菌肥对黄瓜连作障碍抑制效果依次为：多功能木霉菌肥＞护根宝＞连茬王＞金宝贝。

Effects of Different Microbial Fertilizers on Continuous Cropping Cucumber Growth and Soil Physiochemical Properties

A pot experiment was performed to study the effects of 4 microbial fertilizers(Lianchawang,Trichoderma,Jinbaobei and Hugenbao)on continuous cropping cucumber(Cucumis sativus L.)growth and soil physiochemical properties.Results showed that 4 microbial fertilizers significantly promoted the continuous cropping cucumber growth,among which Hugenbao microbial fertilizer had the best effects on vine length,leaf number,leaf dry weight,total plant dry weight and leaf area index of continuous cropping cucumber among...
