运用生物统计学原理对害虫种群自然分布结构进行分布型测定,不仅可以帮助人们对害虫生态特性有进一步的了解,而且可以提高其防治效果以及合理抽样等,因此,国内外已对多种害虫的空间分布型做了测定。在植物病理学方面,虽然近年国内外也作了大量的探讨,不过从病害的特点看,完全通过病害分布型测定,来确定其最优抽样方法还需商讨。1.从有害生物对自然环境的选择看:虽然害虫、病原物都是有害生物,对自然环境的适应也都有一定的共性,但截然不同的是昆虫对环境的选择多是其自身生物学特性的表现,而病原微生物则主要是被
Using the principle of biostatistics to determine the distribution pattern of the natural distribution structure of pest populations can not only help people to know more about the ecological characteristics of pests, but also improve their control effect and reasonable sampling. Therefore, Spatial distribution has been measured. In plant pathology, although a great deal of research has been done at home and abroad in recent years, it is still necessary to discuss the characteristics of the disease completely through the determination of the disease distribution type to determine the optimal sampling method. 1. From pest selection of the natural environment to see: Although pests, pathogens are pests, the adaptation to the natural environment also have some common, but the difference is that the choice of the environment of insects and more their own biology Characteristics of the performance, while the pathogenic microorganisms are mainly being
