棉田棉铃虫着卵株率和百株卵量关系模型的建立与应用
Study on the Relationship between the Baring egg Plant and the Eggs
【摘要】 通过调查研究建立安徽两大棉区棉田不同世代棉铃虫着卵株率和百株卵量关系方程 ,并对方程的准确性和应用该抽样方法的工效进行了检验与比较 ,认为该方法是一种有效的估值手段
【Abstract】 The equations were established between the baring egg frequency plant and the eggs on 100 cotton plants through field investigation,and the equations were proved effective and precise after testing.
