一、前言 1956年2月至1956年10月,我们与湖南省综合农业试验站合作进行了二化螟发育积温的研究。 在提高水稻螟虫防治效果的各种措施中,正确地进行螟虫预测预报工作,尤其是较长期地测报螟虫发生情况是很重要的环节之一。鉴于昆虫生态学上有效积温定律在某些国家的研究、讨论和应用 I. Preface From February 1956 to October 1956, we conducted a study on the accumulation of accumulated temperature in the rice stem borer, Chilo suppressalis Walker, in cooperation with the Hunan Comprehensive Agricultural Experiment Station. In various measures to improve the control effect of rice stem borer, it is very important to correctly carry out the prediction and forecast of stem borers, especially the longer-term detection of stem borers. In view of the insects’ ecological law of effective accumulated temperature in some countries research, discussion and application
