摘要
以秉氏环毛蚓(Pheretima pingi)为实验动物,通过比较秉氏环毛蚓在不同的密度、含水量、温度及酸碱度梯度下的生长发育和繁殖状况,分析蚯蚓繁殖所需的最佳条件,探讨蚯蚓人工养殖的最优方法.结果表明:蚯蚓生长发育和繁殖的最适宜条件是饲养密度为106条/m2、温度为24℃、土壤含水量为20.00%和pH值为6.6.因此,蚯蚓的人工养殖需要提供合适的生长密度、温度、湿度和酸碱度.
To explore the optimum reproductive condition and artificial breeding method for earthworm, Pheretirna pingi was set as the experimental animal, and the comparison of the growth, development and breed status for them under different density, humidity, temperature and acidity or alkalinity gradients was performed in the present study. The results indicated that the condition of 106/m^2 of the raising density, 20. 00% of the soil moisture content, pH 6. 6, and 24℃ was suitable for earthworms growth and reproduction.
