In order to realize the recycling use of spend mushroom compost, the experiment of 7 common decomposition microorganisms mixtures on the mushroom residue maturity were conducted in this study. The results showed that the group T14 which included Bacillus cereus, Bacillus megatrium, Bacillus methylotrophicus, Paenibacillus polymyxa, Trichoderma viride, and Asprgillus niger had a better decomposition effect than others. There had three advantage about T14：The duration over 55 ℃ were 12 days, the number of live bacteria could reach 2.6×107 cfu·g-1 and the pH value and color could be also qualified. There was a significant improvement about the nutrient contents after matured. The contents of TN ,TP ,TK were 21.1, 10.1 g·kg-1 and 25.9 g·kg-1 whichincreased 36%, 66%, and 38% respectively.The organic matter content reduced to 585.4 g·kg-1 after degradation; The results of seed germination and growth test stated that the germination index （GI）of tall fescue seed and perennial ryegrass seed were 1.21 and 1.14, respectively（>0.85）. The stem length and the fresh weight of tall fescue and the perennial ryegrass were increased 24.4%, 29.3% and 33.3%, 36.8%, respectively.The nutrient content of the spent mushroom compost met the requirements of national standards, and significantly promoted plant growth. It was a promising organic fertilizer which had great application value and broad market prospects. [ABSTRACT FROM AUTHOR]

The northern Xinjiang water supply project has been refilled as the largest caliber of fiberglass in China and the technical problems are very prominent, and the pipeline has high demands for raw materials, layers structure, manufacturing and construction and so on. This paper introduced the existing construction of partially inverted siphon project at home and abroad and studied the key technologies such as design parameter determination, pavement design, performance testing, production process, field test and whole process quality control of the glass steel pipe in this project and it had been studied in the cold region, with a diameter of 2. 5 m, the stiffness of the pipe was 8 000 N/ m2, the joint stiffness was more than 25 000 N/ m2 and the maximum allowable vertical deflection of the pipe was 3%.
