摘要
文章研究经过好氧堆肥处理得到的造纸污泥堆肥(PSC)农用的肥效,验证造纸污泥(PS)制有机肥的可行性,为PS资源化利用提供理论依据。本实验利用在赤红壤中添加不同配比的PSC进行玉米盆栽实验,研究PSC农用时有效磷的变化规律,明确PSC的肥效,确定PSC农用的最佳施用量。实验结果表明:(1)综合各方面数据发现,添加PSC有利于玉米的生长,其中6%和10%的配比对玉米生长有明显的促进作用,以10%的植株生长状况最优,土壤保持较高的有效磷含量,肥效最好,是实验中的最优配比。(2)CK中有效磷含量较低,种植的玉米植株生长发育状况较差,明显肥力不足。添加不同配比PSC后土壤的有效磷含量明显升高,其中10%>6%>3%>CK。
The thesis was to study the fertilizer efficiency of farm-oriented paper sludge compost（PSC） which was after the process of good oxygen compost processing,to test and verify the feasibility of manure which was made by paper sludge（PS）,and also to provide a theoretical basis for resource utilization of PS.The experiment was to proceed a corn pot experiment in the lateritic red soil which was added with different matching PSC.During the experiment,the author studied how the determinant changes effected by effective phosphorus when PSC was farm-oriented.Also,the author confirmed the fertilizer efficiency of PSC,and what was the perfect amount of using farm-oriented PSC.The experiment result showed that：（1）Combining all data of the experiment,the author found that adding PSC was good for corns growth.6 % and 10 % in matching was obviously good for corns growth.Growth situation of plants of 10 % in matching was the best.The soil in them maintain abundant effective phosphorus content.The fertilizer efficiency was the best.And this was the optimal matching in the experiment.（2）The effective phosphorus in CK were low.Growth and development of planted corns were not good.That＇s because the fertility of soil was not enough.After adding different matching PSC,the effective phosphorus of soil rised obviously.The matching PSC was ranked as： 10 %〉6 %〉3 %〉CK.
