The results showed that N_2O emission from sanitary landfill decreased dramatically with increasing MSW landfill age after soil cover and its average value,18.

The results show that:all bacteria population and biochemical activity,genus of actinomyces and fungi,and soil nutrients on covered area with soil were better than those on coal gangue hills without soil cover.

Physical and chemical properties of three industrial or agricultural wastes and their influence on growth of the mushroom(Agaricus bisporus) as casing soil;

Physical and chemical properties,culturable bacterial population and phospholipid fatty acid(PLFA)profile of different casing soils at different mushroom(Agaricus bisporus)cropping stages were investigated.

appraised and analysized the productive properties of three kinds of Agaricus bisporus by its cultivated property,yield and nutritional components of fruitbodies,analysized the effects of the XSJ fermentation on the cultivated property and yield in Agaricus bisporus ,and studied the pattern of casing soil using Fus.

Experimental study on anti-impact properties of a partially prestressed concrete beam with covering soil;

The mesh spot pattern is used for sampling covering soil at ecological environment recovering test field, which is reclamation area filled by coal mining wastes for cropland in the north of Jingtian coal mine, Laohutai, Fushun.

Casing at the period when hyphae occupied 90% of cultural medium could produce the highest yield,it was 16 42% and 26 35% higher than other two treatments (oc.
