受自然和生物因素所制约的田间二代棉铃虫卵发生数量的消长情况,可由一系列表观的自然生态因素和棉铃虫本身的生物因素所构成的指标群组合来刻划,每一因素在客观上均反映了该因素适宜棉铃虫卵发生数量消长的程度。然而,适宜棉铃虫卵发生数量消长的程度,却是一个存在着中间过渡状态的FUZZY概念,因此,我们引入FUZZY数学,应用FUZZY贴近度原理,并结合数理统计分析,来对田间二
The growth and decline of the number of second-generation cotton bollworm eggs in the field under the control of natural and biological factors can be scored by a combination of indicators consisting of a series of apparent natural ecological factors and the biological factors of the cotton bollworm itself. Objectively reflect the factors suitable for the occurrence and decline of the number of cotton bollworm eggs extent. However, it is a concept of FUZZY that there exists an intermediate transitional state for the degree of occurrence and quantity of H. armigera eggs. Therefore, we introduce FUZZY mathematics and apply FUZZY closeness principle, combined with mathematical statistics analysis,
