本文根椐多年生产实践和计算机理论,利用BASIC语言编制了预测二代棉铃虫卵始、盛、末期的计算程序,供地、县级病虫测报人员参考试用。1 程序依据山东省农科院棉花研究所许立瑞先生在山东省第4期病虫测报培训班上讲授的“麦田一代棉铃虫幼虫残虫发育进度分龄推算预测二代棉铃虫产卵期”的理论和推算方法。该方法预测超前性强、时间准确、计算方法简便。
Based on years of production practice and computer theory, this paper compiled a program to predict the start, end and end of the second generation cotton bollworm eggs by using BASIC language. 1 program based on Shandong Academy of Agricultural Sciences Institute of cotton Xu Lirui Shandong Province in the fourth pest forecasting training course taught in “wheat field a generation of cotton bollworm larvae progress on the basis of the progress of age estimated that the second generation cotton bollworm spawning period” Theory and calculation method. This method has the advantages of strong prediction, accurate time and simple calculation method.
