猪粪堆腐对不同种子发芽指数的影响

Effect of Pig Manure during Composting on Germination Index of Different Seed

采用高温好氧模拟堆腐试验,研究了猪粪腐解过程中对不同种子发芽指数的影响。结果表明:在堆腐过程中的温度和pH均呈现出先增加后下降,而后平稳的趋势。同一堆腐时期,不同种子的发芽指数明显不同,其中小白菜种子最为敏感,而黄瓜种子表现出的抗性最强。因此,可以选择小白菜作为猪粪无害化生物学指标的指示种子。

Using the method of high temperature aerobic composting,the effect of pig manure on germination index of different seed were studied.The results showed that temperature and pH firstly increased rapidly,then decreasing and finally becoming stable in the process of pig manure composting,different seed germination index was significantly different in the same composting.The most sensitive seeds was Chinese cabbage,and cucumber seeds showed the strongest resistance.Therefore,Chinese cabbage can be as a biological indicators seeds of pig manure.
