摘要
研究了不同碳源（葡萄糖、果糖、可溶性淀粉、蔗糖、麦芽糖和乳糖）、氮源（硝酸钾、硫酸铵、尿素和硝酸铵）、C/N（40：1、20：1、8：1）、p H值（5.0、6.0、6.5、7.0、7.5、8.0）及温度（24、26、28、30、32、34、36益）对油茶根际解磷菌6-Y-09溶磷能力的影响。结果表明院以葡萄糖为唯一碳源时解磷菌6-Y-09表现出最强的解磷效果,溶磷量达201.51 mg/L;以尿素为唯一氮源时,解磷菌6-Y-09表现出最强的解磷效果,溶磷量达215.43 mg/L;解磷菌6-Y-09最佳C/N为20：1,最佳p H值为7.0~7.5;另外,解磷菌6-Y-09在28~30益时表现出最强的解磷效果。
The ability of phosphate solubilizing by strain 6-Y-09 in Camellia oleifera Abel. with different cultivation conditions,including different carbon sources （glucose,fructose,soluble starch,sucrose,maltose,lactose）,different nitrogen sources （potassium nitrate,ammonia sulfate, urea＇,ammonium nitrate） ,different C/N（40：1,20：1,8：1 ） ,different pH value（5.0,6.0,6.5,7.0,7.5,8.0） ,different temperatures （24,26,28,30,32,34, 36 ℃ ）were studied. The results showed that strain 6-Y-09 had the highest phosphate solubilizing when glucose was used as carbon source, the released soluble P was 201.51 mg/L. When urea was used as nitrgoen source, the released soluble P by strain 6-Y-09 was 215.43 mg/L.In addition, strain 6-Y- 09 had the highest caoacitv of ohosohate solubilization when C/N was 20：1. oH value was 7.0-7.5. and the temnerature was 28-30℃.
