12.07和0.76，堆肥颜色呈黑色、无气味、温度降至常温时，蚕沙堆肥达到充分腐熟。因此，蚕沙堆肥处理过程中的堆肥颜
色、气味、温度、C/N、T 值及发芽指数与蚕沙好氧堆肥腐熟度紧密相关，可作为蚕沙好氧堆肥腐熟度快速评价指标。

| Abstract: | Compost maturity is the main parameter to evaluate the composting process and compost product quality,
but research on maturity indexes of silkworm excrement composting was seldom. To explore the rapid evaluation system of
maturity about silkworm excrement composting, the model of static -aerobic composting was adapted to three types of
compost, the main composting material was silkworm excrement, and the conditioners were spent mushroom compost and
chaff, then investigated the change rules of physical, chemical and biological properties, and made a correlation analysis on
various indicators. The results showed that when the germination index reached 80% or above, C/N and T value dropped to
12.7 and 0.76, the compost color became black, the smell disappeared, and the temperature dropped to normal temperature,
the silkworm excrement would become thoroughly decomposed. So that the color, smell, temperature, C/N, T value and
germination index of silkworm excrement composting were close related to the maturity of silkworm excrement aerobic
composting, and could be used as the rapid evaluation indexes of maturity of silkworm excrement aerobic composting. |
