研究表明,单独施用无机肥料虽可保持带田高产,但只有与有机肥料配合时才能促进土壤有机质的积累;带田生产中氮肥损失率不低于42.1%~54.7%,说明改进施肥方法、提高氮肥利用率仍是带田合理施肥的关键;施用无机磷肥特别是与有机肥配合施用是提高土壤磷肥力的有效措施,可提高有机磷含量及其占总磷量的比例,提高无机磷中有效及缓效组分所占比例,降低难溶组分(Ca10-P,O-P)的比例;带田耗钾强度高,必须注意钾肥的投入
The results showed that inorganic fertilizers alone could maintain a high yield in the field, but could only promote the accumulation of organic matter in the soil when they were mixed with organic fertilizers. The nitrogen loss rate in the field was no less than 42.1% ~ 54.7% Fertilization methods and improving nitrogen use efficiency are still the key factors of rational fertilization in the field. Application of inorganic phosphate fertilizer, especially with organic manure, is an effective measure to increase soil P fertility, which can increase the proportion of organic phosphorus and its proportion of total phosphorus, The proportion of effective and slow-acting components in inorganic phosphorus and the proportion of insoluble components (Ca10-P, O-P); the high potassium-consuming intensity in fields, it is necessary to pay attention to the input of potash fertilizer
