根据广东省农科院蚕研所蚕病研究室的实验结果(1980)认为,对“秋303”、“137”及“农42”3个品种患有微粒子病的蚕种,在产卵后18小时,用1.05比重的盐酸在47℃下浸酸处理10-20分钟,经3龄眠蚕显微镜检验表明,可以比原来的发病指数减少97%以上.说明高温即时浸酸处理对家蚕微粒子病的经卵传染,具有明显的治疗效果.为了进一步验证这一实验室的试验结果,1981年,我们在南海县蚕种生产和养蚕生产实践中进行了高温即时浸酸防治家蚕微粒子病的中间性生产试验.试验时间是在5-7月微粒
According to the experimental results of silkworm research laboratory of Guangdong Provincial Academy of Agricultural Sciences (1980), it is considered that there are three kinds of silkworm in the three varieties of “autumn 303”, “137” and “peasant 42” After 18 hours of spawning, pickling with 1.05% hydrochloric acid at 47 ℃ for 10-20 minutes showed that the index of disease could be reduced by 97% or more compared with the original index, In order to further verify the experimental results of this laboratory, in 1981, we carried out high temperature instant pickling in silkworm production and silkworm production in Nanhai County Intermediates in the control of silkworm micro-particle disease production test time is in May-July particles
