有关麦类赤霉病流行学研究的报导较多,并提出了一些预测式。尤其是近年来,多元回归分析(MRA)和电子计算机的应用,为大量资科进行分析提供了一种简捷有效的手段。麦类赤霉病流行规律和预测预报的研究正在由定性向定量化发展。本文是在一些流行因子试验观测的基础上,利用电算技术进行因子相关分析和回归分析,提出一些适用于我省嘉兴地区麦类赤霉病长、短期预报的回归预测式。
There have been many reports on the epidemiology of wheat scab and some predictive formulas are proposed. Especially in recent years, multiple regression analysis (MRA) and the application of electronic computers provide a simple and effective method for analyzing a large number of resources. The research on the epidemic regularity and prediction of wheat scab belongs to the qualitative and quantitative development. This article is based on the observation of some epidemiological factors, using the computer technology for factor correlation analysis and regression analysis, and puts forward some regression prediction formulas suitable for long and short-term forecast of wheat scab in Jiaxing area in our province.
