饲养夏秋蚕产量不稳,其主要原因是蚕病危害严重。夏、秋季的气候特点是:温度高、湿度大。这时桑树生长快,产叶量高。蚕儿生长快、龄期短,可分批多次饲养,充分利用桑叶,提高蚕茧产量。但是,夏秋季温度高,湿度大,也有利于病原菌繁殖蔓延,加之前后批饲养相隔时间短,积累的病原菌多,易感染蚕病,从而增加了饲养的困难,所以,养好夏秋蚕,防病是关键,必须认真贯彻“以防为主、防重于治”的方针,做好饲养前的防病消毒工作,把 The feeding of summer and autumn silkworm yield instability, the main reason is serious damage silkworm disease. The climate characteristics of summer and autumn are: high temperature and high humidity. At this time mulberry grow fast, leaf yield high. Crane grow fast, short age, multiple batches can be batches, make full use of mulberry leaves, improve cocoon yield. However, the high temperature in summer and autumn, humidity, but also conducive to the spread of pathogenic bacteria, combined with before and after the grant interval time is short, the accumulation of pathogens and more susceptible to silkworm disease, thereby increasing the difficulty of feeding, so feeding summer and autumn silkworm, prevention Disease is the key, we must conscientiously implement the principle of “prevention is the priority, prevention is more important than cure”
