要获得一年多批养蚕的成功,必须为蚕室创造优越的小气侯,使幼蚕有个适宜的环境。温度:温度与家蚕生长发育关系十分密切,蚕儿只有在适宜的温度下才能正常生长发育。然而,春、夏、秋养蚕季节,自然气温常是“山峰”式波动出现,高低交叉,反复多变,形成春季“前低后高”和秋天“前高后低”的规律。早春和晚秋的寒冷、夏季和早秋期的高温天气是常有的。因此,防
To obtain the success of multiple batches of silkworms in more than a year, we must create a superior microclimate for the Jamsil so that the young silkworms have a suitable environment. Temperature: The temperature is closely related with the growth and development of silkworms. The silkworms only grow and develop normally under suitable temperature. However, the spring, summer and autumn sericulture season, the natural temperature is often “mountain” -style fluctuations occur, the level of cross, repeated changes, the formation of the spring “before the low after the high” and fall “before the high after the low” law. Cold in early spring and late autumn, high temperatures in summer and early autumn are common. Therefore, anti
