摘要
通过对亚铵法制浆废液氨解产物为原料研制的复混肥进行盆栽试验,探索其对肥料中氮、磷利用率的影响,为亚铵法制浆废液的资源化利用提供一理想途径。盆栽试验结果表明,以亚铵法制浆废液氨解产物为原料研制的复混肥,具有缓释作用,能够抑制肥料中氮的释放速度,提高氮的利用率;并能增强磷在土壤中的溶解,促进磷的活化,提高磷的利用率。
This paper made the potted plant experiment with the method of the cop pound fertilizer which is made of the modification of ammonia sulfite pulp black liquid, and explored the method infect the utilization ratio of N and P, in order to provide a ideal way for its resource utilization. The result of the pot experiment shows that the methods can improve the utilization ratio of N and P by suppressing the releasing speed of N in the fertilizer and promoting the activity of P in soil.
