Abstract:
Cucumber was used as test materials，a pot experiment was conducted to study the effects of different biochar application rate (according to the continuous cropping soil mass ratio of 1%，3%，5%，7%，9%) on soil properties，microbial quantity and cucumber growth.The results showed that the moderate biochar could significantly reduce soil bulk density and EC value，increase field capacity，pH and rapidly-available potassium content，reduce soil fungi and fusarium oxysporum quantity，but improve bacteria quantity and B/F (bacteria/fungus) ratio，thus the cucumber root zone soil micro ecological environment was improved，promoting the cucumber growth and yield.Therefore，the biochar dosage at a level of 5% was more appropriate in this experiment by comprehensive analysis，which could be used as measures to improve continuous cropping soil in the actual production.
