摘    要:通过室内模拟培养和大豆盆栽土培生物模拟试验,研究了磷细菌溶解磷酸钙的能力及在北方石灰性土壤上施用磷细菌肥对土壤磷素转化的影响。试验结果表明:磷细菌菌株具有较强溶解磷酸钙的能力,磷酸钙的溶出率从第1天的2.80%提高到第8天的22.00%。在贫速效磷和富难溶性磷土壤上施用溶磷细菌肥有利于土壤中难溶态的Ca10-P和缓效态Ca8-P含量下降,促使土壤中Ca2-P和Al-P的含量增加,从而使土壤中有效磷含量增加。而对于富速效磷的土壤,无论施菌肥与否对土壤中各种形杰的无机磷绢分基本没有影响.

关 键 词:溶磷细菌 土壤速效磷 无机磷

Abstract:The soybean experiment was conducted in pot with calcareous soil in north China.By the design method of complete random block.The result had shown that its function was obviously different in different phosphorus form soils.The Psolubilizing ability was low in the poor available phosphate soil.Phosphorus bacteria fertilizer couldn't improve the content of available phosphate in rich available phosphate soil.But the P-solubilizing ability was best in rich sparingly soluble phosphate soil.As were shown by the followings: Phosphorus bacteria fertilizer could decrease the content of sparingly soluble Ca_(10)-P and alleviate-soluble Ca_8-P,and increase the content of Ca_2-P and Al-P inthe poor available phosphate soil and in the rich sparingly soluble phosphate soil.So it increased the content of soil available phosphate.But in the rich available phosphatesoil wheather using phosphorus bacteria fertilizer or not had little effect to various inorganic phosphorus forms.
Keywords:phosphorus bacteria fertilizer   available phosphorus   inorganic phosphorus
