摘要

A study on the characteristics of composting processes and products was conducted by piling used mushroom culture medium with soybean oil extract waste and bone meal (A treatment), chicken dropping (B treatment), hog feces (C treatment), urea and perphosphate (D treatment), under the condition of initial carbon/nitrogen (C/N) was 30, moisture content was around 60%, piling volume was slightly more than 1 m3 (1 l x 1 w x 1 h) and turning frequency was every 10 days. The result showed that treatment A, B, C, D required 80, 20, 50,110 days, respectively, to become matured composts with C/N ratio lower than 15. However, evaluating matured compost on the base of almost no temperature raising after turning those piles for several days, treatment A, B, C, D need around 72, 51, 58, 77 days, respectively. The maturity days of each treatment was different while judging them on different criteria, but the order of maturing speed were still the same as treatment B＞C＞A＞D. The result of biological test indicated that the germination percentage of cabbage seed in 1:5 (w/v) water extract solution didn't increasing with piling days and showing the unstable tendency. Then, it is difficult to be as a criterium for the treatments in assessing maturity degree. However, cabbage seed could germinated more than 70% in same water extract solution from each treatment with 70 days piling.The treatments could become matured composts after piling for 110 days and the products properties are as followings: (1) pH is in the range of 7.5~8.5. (2) electrical conductivity (EC) is more than 4 mS/cm for A and B product and less than 4 mS/cm for C and D products. (3) carbon content is between 30 and 36%. (4) total nitrogen content is in the range of 2.0~2.5% and product A is the highest while product D is the lowest. (5) product B has the highest phosphorus, potassium, calcium and magnesium contents among the four products.The result of primary test showed that the initial effect of the products on cabbage growth didn't have a positive relationship with the total nutrient content. In other words, effect of different compost treatments on the early stage of the growth of cabbage was not coincided with the order of the total nutrient content.
