| 摘 要： | 为了研究增施解磷菌肥对土壤供磷状况的改善和土壤中磷有效性的提高状况,通过田间小区试验研究了连续施用解磷菌肥对复垦5年土壤碱性磷酸酶活性及Hedley磷形态的影响。结果表明:施用无机肥+有机肥+解磷菌肥处理的土壤碱性磷酸酶活性最高,为30.65μg/(g·h),比对照提高了83.86%。本试验年与第3年复垦土壤相比,土壤中Hedley磷形态的含量都有不同程度的增加,H_2O-Po含量以无机肥+有机肥+解磷菌肥处理为最高,比对照提高了93.90%;NaOH-Pi、HCl-Pi、HCl-Po含量以无机肥+解磷菌肥处理最大,分别比对照提高了194.2%、61.87%、105.8%;残渣态磷含量以无机肥处理影响最大,比对照提高了22.87%;H_2O-Pi、NaHCO_3-Po含量以有机肥处理最大,比对照提高了129.2%、85.89%;NaHCO_3-Pi、NaOH-Po含量以有机肥+解磷菌肥处理提高最大,分别提高了176.9%、114.4%。可以得出:施用解磷菌肥的处理增加复垦土壤中H_2O-Po、NaHCO_3-Pi、NaOH-Pi、NaOH-Po、HCl-Pi、HCl-Po含量的效果较好。H_2O-Pi、H_2O-Po、NaHCO_3-Pi、NaHCO_3-Po、NaOH-Pi、NaOH-Po、HCl-Pi与碱性磷酸酶均呈极显著相关。解磷菌肥在一定程度上增强了复垦土壤碱性磷酸酶活性,影响土壤中Hedley磷分级的各形态磷素含量,从而提高磷的有效性。

| Abstract: | In order to study the effect of increasing application of phosphorus bacterial fertilizer on soil phosphorus supplyand phosphorus validity, the effects of continuous application of P bacterial fertilizer on alkaline phosphatase activity activityand Hedley phosphorus forms were studied by field experiments in 5 year reclamation soil. The results showed that: Alkalinephosphatase activity in the treatment with application of inorganic fertilizer + organic fertilizer + phosphorus bacterial fertilizerwas the highest, which was 30. 65 μg/(g?h) and increased by 83. 86% than that of the control. Compared to thethird year of reclamation soil, the contents of different forms of Hedley phosphorus in soil were increased in different degrees,the H2 O-Po content of inorganic fertilizer + organic fertilizer + phosphorus bacterial fertilizer treatment was the highest,increased by 93. 90% than the control. NaOH-Pi, HCl-Pi, HCl-Po contents of inorganic fertilizer + phosphorus bacterialfertilizer treatment were the largest, increased by 194. 2%, 61. 87%, 105. 8%, respectively. The effect of inorganicfertilizer on phosphorus content in compound fertilizer residue was the greatest, which was increased by 22. 87% than thatof CK. The contents of H2 O-Pi、NaHCO3 -Po of organic fertilizer treatment were the highest, which were increased by129. 2%, 85. 89% than those of the control. NaHCO3 -Pi, NaOH-Po contents of organic fertilizer phosphorus bacterial fertilizertreatment were the maximum, increased by 176. 9%, 114. 4%, respectively. It was concluded that the applicationof phosphorus bacterial fertilizer treatment had the better effect to the content of H2 O-Po, NaHCO3 -Pi, NaOH-Pi, NaOHPo,HCl-Pi、HCl-Po in reclaimed soil. H2 O-Pi, H2 O-Po, NaHCO3 -Pi, NaHCO3 -Po, NaOH-Pi, NaOH-Po, HCl-Piwere significantly related with alkaline phosphatase. Phosphate bacterial fertilizer enhanced the reclaimed soil alkaline phosphataseactivity to some extent, influenced soil content of different forms of phosphorus in Hedley grade of phosphorus, andenhanced the effectiveness of phosphorus. |
