农村原蚕饲养微粒子病检查批内分布规律研究

对 4 78个农村原蚕批的 4 92 7个农户母蛾微孢子带毒状况做了统计分析。结果表明 :各原蚕批内的不同饲养户带毒情况具有一定的相关性 ,但不完全相关 ,其分布既不同于蚕种统批制种的批内呈随机分布 ,也不同于各批间呈独立分布。因而指出有必要制定农村原蚕批分户制种的微毒检验标准和抽样方案。

Studies on the Distribution Law of Pebrine Within Batches of Parent Silkworm Rearing

In this paper,the pebrine infection of mother moth from 4 927 farmers of 478 batches in parent silkworm rearing area was made statistical analysis.The research results showed that the pebrine infection was correlation between the different farmers in parent silkworm rearing areas,but not all correlative,whose distribution were neither random within batch and nor independent each other between different batches in silkworm eggs production farm So we think that it is necessary drawing up the pebrine inspection standards and sampling scheme for the parent silkworm rearing area.
