摘  要：
以小油菜为试材,用自行分离出的5株解磷细菌制成液体菌剂,进行盆栽试验。结果表明:不论施磷肥与否,使用解磷细菌可以提高小油菜的产量,其中溶磷菌w12-7和解磷菌y9-4处理的小油菜的产量提高的最多,其次为溶磷菌w5-2处理的小油菜;作物收获后,土壤速效磷含量变化较大,不施磷肥时,使用溶磷菌w12-7和解磷菌y9-4的土壤速效磷含量降低较少,分别比对照变化值少23.4%和34.8%;施磷肥后,所有处理的速效磷含量均有所增加,且溶磷菌w5-2和解磷菌y9-4处理增加较多。解磷细菌对土壤pH和全磷含量影响不明显;溶磷菌w12-7、w5-2和解磷菌y9-4较适用于青海省石灰性土壤中。

摘  要：
Taking rape as material,phosphorus inoculum was prepared by phosphorus dissolving bacteria strains which were separated by our group for rape pot experiment.The results showed that regardless of fertiliziting P or not,using solubilizing bacteria could significantly increase the rape yield,which improved the production mostly were phosphorussolubilizing bacteria w12-7and phosphorus bacteria y9-4,followed by phosphorus-solubilizing bacteria w5-2.After harvesting,soil available-P content changed widely.When none fertilizer P,the content of soil available-P was decreased on the condition of phosphorus-solubilizing bacteria w12-7and phosphorus bacteria y9-4,less than the control change value of 23.4%and 34.8%.Under the condition of P fertilizer,available P content of all treatments was improved,which improved the production mostly were phosphorus-solubilizing bacteria w5-2and phosphorus bacteria y9-4.It was not obvious of the effect of P solubilizing bacteria on soil pH and total phosphorus.Tests showed that phosphorus-solubilizing bacteria w12-7,w5-2and phosphorus bacteria y9-4were better strains used in calcareous soils in Qinghai.
