Abstract:

Asparagus straw were used as composting materials to study the effects of different inoculants(CK, self-made bacteria, EM bacteria, Dacheng bacteria) on the composting temperature, pH value, EC, total carbon content, total nitrogen content, and seed germination index. The results indicated that inoculating with self-made bacteria and Dacheng bacteria could significantly accelerate the heating rate, prolong the duration of high temperature. The inoculants had a minimal impact on the pH value and EC of the fermentation product, but could significantly reduce the total carbon content. Inoculants could significantly increase the seed germination index, accelerate the composting maturation process, especially with the self-made bacteria and Dacheng bacteria treatments, asparagus straw could mature 14 days earlier than CK.

Key words: inoculant, asparagus straw, compost, decomposition
