病虫害防治好坏,与测报准确与否有关,随着人们对农业生产领域中各种量的研究愈趋深入,统计分析也愈来愈广泛地应用。这为简化测报方法,提高测报技术打开了大门。一、用直线回归方法预测越冬代红铃虫蛾峰以往越冬代红铃虫的蛾峰预测,采用收拾越冬红铃虫进行玻管饲养,以化蛹高峰加上蛹期来预测蛾峰。但这样做化工大,从5月初到7月中要每天化去二、三小时,且由于收拾幼虫时若代表性不当或饲养放置不妥,会严重影响准确度,若遭到谷羊螨寄
The control of pests and diseases is good or bad, which is related to the accuracy of the measurement. As more and more studies on all kinds of agricultural production have been made, statistical analysis has been applied more and more widely. This opens the door to simplified reporting methods and better reporting techniques. First, using the linear regression method to predict overwintering pink bollworm moth moth peak Overwintering pink bollworm moth peak prediction, the adoption of the winter red bollworm tube for keeping, pupation peak pupation period to predict the moth peak. However, in order to do this large chemical industry, from the beginning of May to mid July, it takes two or three hours a day, and if the improper representation or improper placement of larvae when draining larvae will seriously affect the accuracy,
