连续施用解磷菌肥对复垦土壤有机质和有机磷组分的影响

Effect of Continuous Application of Phosphorus Bacterial Fertilizer on Soil Organic Matters and Organic Phosphorus Fractions of Reclamation

为提高复垦土壤肥力,本文通过田间小区试验,研究了解磷菌肥对复垦五年土壤有机质和有机磷组分含量的影响。结果表明:与对照相比,不同施肥处理对土壤的有机质和有机磷各组分含量有不同程度的提高。施用腐熟鸡粪+解磷菌肥处理土壤有机质含量提高最大,提高了41.99%;晨雨复合肥+解磷菌肥、腐熟鸡粪+解磷菌肥、晨雨复合肥+腐熟鸡粪+解磷菌肥这3个处理与其未施用解磷菌肥的处理相比,活性有机磷含量分别提高了24.45%、15.94%、13.44%;中等活性有机磷含量分别提高了97.00%、4.08%、0.73%;高稳性有机磷含量分别提高了5.70%、35.63%、6.23%,而中稳性有机磷含量却降低了。这3个处理相比,腐熟鸡粪+解磷菌肥处理对土壤有机磷各组分影响效果较好。增施解磷菌肥提高了复垦土壤有机质含量,影响有机磷各组分含量,从而提高磷的有效性。

To improve the reclimed soil fertility We used field plot tests to studied the effects of application of phosphorus bacterial fertilizer on five years of reclamation soil organic matters and organic phosphorus components.The results showed：Compared with CK,different fertilization treatment could greatly improve the soil organic matter and organic phosphorus content of each component.Application of chicken manure ＋ phosphorus bacterial fertilizer treatment,the organic matter increased to a maximum of 41.99％;and compared the 3 treatments of Chenyu fertilizer ＋ phosphorus bacterial fertilizer,the chicken manure ＋ phosphorus bacterial fertilizer,the Chenyu fertilizer ＋ chicken manure ＋ phosphorus bacterial fertilizer respectively,with the without application of phosphorus bacterial fertilizer,active organic phosphorus were increased by 24.45％,15.94％,13.44％;moderate active organic phosphorus were increased by 97.00％,4.08％,0.73％;high stable organic phosphorus were increased by 5.70％,35.63％,6.23 ％,and stable organic phosphorus was decreased.Compared with the 3 treatments,chicken manure ＋ phosphorus bacterial fertilizer treatments on soil organic phosphorus fractions was in good effect.Showed that application of phosphorus bacterial fertilizer improved organic matte of the reclaimed soil,effected the organic phosphorus content of each component,so as to improved the availability of phosphorus.
