赤子爱胜蚓对几种不同原料制得饵料的利用研究

The Utilization of the Bait Prepared by Several Different Raw Materials of Eisenia fetida

摘要: 文章通过室内模拟试验研究了利用畜禽粪便与蝉花菌质、作物秸秆制得蚯蚓养殖饵料饲喂蚯蚓对蚯蚓生存环境下土壤养分含量的影响。结果表明，pH均显著降低，土壤呈偏酸性；全磷、有效磷含量均显著增加；除对照组以外，有机质、全氮、硝态氮含量显著增加；对照组的铵态氮含量显著增加；全钾含量在试验前后无明显变化。综合分析各处理间的处理效果，可得出：h3 > h1 > h2 > h4，即鸡粪与蝉花菌质、作物秸秆堆置发酵制得的蚯蚓养殖饵料，在经蚯蚓利用后，对土壤养分含量提高效果最为明显。

Abstract: In our study, we conducted the changes on the soil nutrient content in the earthworm living envi-ronment by used poultry manure, cicada flower fungus and crop straw to raise the earthworm. The results showed that the pH decreased significantly and the soil shows acidity. It’s prominently that the total content of phosphorus and available phosphorus content was increased, and except for the control group, the organic matter, total nitrogen, and nitrate nitrogen content increased in other groups; Moreover the ammonium nitrogen content in the control group remarkably increased; However the total potassium content did not change between experiment. All of the result indicated that: h3 > h1 > h2 > h4, which means that the bait made by chicken manure, cicada flower fungus, and crop straw used by earthworm can increase nutrient content obviously.
