每年冬、春是蚯蚓生长繁殖的缓慢季节,而且稍不注意,还会引起死亡或逃逸。其原因主要与气温有关。以成蚓产卵数为例,日平均气温高,蚯蚓产卵就多,孵化也快;反之则产卵少,孵化慢。是否能采取措施,变蚯蚓的冬眠为冬繁呢?笔者为此目的进行了蚯蚓越冬措施的研究。现将结果简报如下。一、试验处理与经过试验选用三个养殖场所——室内地面、室外地面、室外挖窖,每个养殖场所又用三个生熟不同比例的饵料——全部熟粪(简称全熟),1/3底生2/3面熟(简称面熟),和2/3底熟1/3面生(简称面生)进行对比。地面养殖的用直径30Cm,高40Cm的陶瓷小缸进行;挖窖的窖深1米,长、宽各0.7米。
Every winter, spring is a slow season of earthworm growth and reproduction, and a little careless, but also cause death or escape. The main reason is the temperature. To earthworm number of eggs, for example, the average daily high temperature, earthworms spawn more hatching faster; otherwise less spawning, hatching slow. Is it possible to take measures to change the hibernation of earthworms for the winter? I for this purpose carried out the study of earthworms overwintering. The result is now as follows. First, the experimental treatment and after the test selection of three breeding sites - indoor ground, outdoor ground, outdoor dig pits, and each farms with three raw materials of different proportions of raw and cooked - all cooked manure (referred to as full cooked), 1 / 3 bottom 2/3 cooked (referred to as cooked), and 2/3 maturity 1/3 surface Health (referred to as raw) for comparison. Ground culture with a diameter of 30Cm, 40Cm high ceramic small tank; pit cellar deep 1 meter, length, width of 0.7 meters.
