摘要: 通过对N、P、K不同施肥条件下的“秦油2号”油菜植株内含物与桃蚜种群消长关系的研究与分析,建立了9个数学模型,结果表明可溶性糖含量、含K量、含水量对桃蚜种群消长影响最大;低N、低K、中P组合对桃蚜种群增长不利.

Abstract: The influence of contents in "Qinyou 2" rape under application of different rates of N, Pand Kfertilizers of Myzus persicae is studied, and nine mathmatical models are established. The results show that soluble carbohydrates, potassium and moisture contents in rape plants affect significantly the population dynamics of Myzus persicae. The combination of lower Nand Kand midium Pis disadvantageous to Myzus persicae population growth.
