不同施用方式下污泥堆肥对土壤性质和草坪生长的影响
Effect of Sludge Compost on Soil Quality and Turf Growth Under Different Applying Methods
摘要
Abstract
In order to solve the difficult problems of sludge disposal and discuss the effect of sewage sludge compost and the different application methods on soil remediation in urban greenblts,soil improvement experiments were carried out.Three treatments included blending（H）,the mulching（F）,blending and mulching（HF） were designed.The results showed that all the three application methods could reduce the soil bulk density,increase the content of soil organic matter,alkali-hydrolyzable N,available potassium and phosphorus significantly,H and HF were the ideal application methods.All the three application methods also presented significant promotion on the lawn growth rate,tiller density.The number of turf tiller density of HF,F,H treatments increased by 45%,37% and 32% compared to CK,respectively.More than 96% of weed population was reduced with F treatment,the inhibition rate with HF treatment was 78% and there was no inhibiting effect with H treatment.The soil microbial biomass C and N（MBC,MBN） also were markedly increased with the different application methods.After one year,the contents of soil MBC of F,H,HF were 2.4,3.1,3.4 times as that in CK respectively,and the soil MBN of F,H,HF were respectively 1.7,3.0,2.8 times to CK.Compared to CK,the activities of soil urease,acid phosphatase and invertase with HF and H were also increased remarkably.关键词
