摘要
本文提出了一种植物抗虫性鉴定的新方法——模糊识别方法。初步看山,应用此法进行冬小麦抗麦长管蚜 Sitobion avenae(F.)的鉴定,与传统使用的蚜情指数法相比,可避免数虫费工之弊,在蚜虫高峰期鉴定时能提高效率61倍,结果可靠且具有较好的相对稳定性。
In this paper,a new method,fuzzy recognition,for identifying theplant resistance to insect was proposed.By applying this method,anappraisal of the resistance of winter wheat to Sitobion avenae(F.)wascarried out.The results was reliable and possessed better space stabi-lity,and the working efficency was raised about 61 times as comparedwith the old routine,aphid injury index method.
