调理料对猪粪好氧堆肥特性的影响试验

以猪粪为原料，添加质量分数为10%、15%、20%的小麦秸秆、玉米秸秆、木屑3种调理料进行好氧堆肥试验，5d人工翻堆一次。结果表明：以小麦秸秆和玉米秸秆为调理料的堆置效果比其他调理料效果更好。提高经过处理的玉米秸秆比例能获得更好的堆肥效果，当增至20%，能获得比以小麦秸秆为调理料更佳的堆肥效果；而以小麦秸秆为调理料的好氧堆肥的最佳比例为15%；小比例的木屑堆肥效果相对次之。

Effects of Different Materials Addition on the Aerobic Composting

Wheat straw, corn stover, and saw dust were added into the main composting material, swine manure, respectively to study the effects on the aerobic composting. Dry weight of each material was 10%, 15% and 20% of the total dry weight respectively. The piles were turned over once every 5 days by labor. By the comprehensive research, the composting with materials of wheat straw and corn straw were better than others. The result showed adding more corn straw could get better effect, increasing the proportion of corn straw (when the proportion of corn straw reached 20%) can gain better composting effect than adding wheat straw, while the best proportion of wheat straw was 15%, under that condition, the best effect of composting could be obtained. The composting with litter ration of saw dust was relatively poor.
