摘要
本文研究了麦蛾在28℃、75%RH下的种群增长,建立了种群增长的Logistic growth模型;麦蛾种群数量增长使小麦千粒重、发芽率、蛋白质舍量和淀粉含量降低,小麦水分含量、游离脂肪酸含量和尿酸含量增加.小麦品质的变化与麦蛾种群的增长有密切的关系,建立了相应的数学模型,根据麦蛾种群数量的变化可预测小麦品质的变化和受污染的程度.
This paper dealt with the population dynamics of Angoumois grain moth at the 28℃ and 75% R.H.. The Logistic growth model was established. The mean weight of 1000 kernels, the germination percentage, the protein and starch content of wheat reduced and the moisture content of wheat, the percentage of free fatty acid and the uric acid of wheat increased with the increase of the population of the A. grain moth. The mathematic models were established between the change of the quality of wheat and the growth of the population of the A. grain moth. The models may be used to predict the changes of the quality and contamination of wheat based on the growth of the A. grain moth.
