树皮与污泥堆肥混合基质的性质及其对黑麦草无土草坪的影响
Properties of the Media Mixed with Bark and Sewage Sludge and Its Effects on Soil-less Lawn of Ryegrass
摘要
Abstract
In order to solve the problems of sewage sludge compost's compaction and poor permeability, the experiment was conducted to study the effect on ryegrass characteristics by using the bark compost as the adjust material and fixing the different amount of bark compost with sewage sludge compost, and explored the impact of different bark compost amount to the physical and chemical properties of sewage sludge. The results showed that the emergence rate, plant height, growth rate, number of tillers and root activity of ryegrass increased by 10%, 52.5%, 31%, 61.9% and 53.9%which were grown at the mixture of 50%bark compost and 50% sewage sludge compost when compared to pure sewage sludge compost. The total porosity, aeration porosity and permeability coefficient were increased by 2.7%~9.1%, 2.17~4.40 times and 1.84~5.1 times in adding bark compost than that of pure sewage sludge compost respectively, while the bulk density, water holding porosity, WAP/AP, EC and nutrient content decreased gradually with the increasing amount of bark compost. The total results indicated that adding bark compost could affect the physical and chemical properties of sewage sludge compost significantly, and the addition amount of 50%bark compost has the best effect on ryegrass roots and aerial growth, and it could be ryegrass soil-less lawn's ideal growing media.关键词
