| 摘 要： | 农作物病虫害风险的研究,对有效防御病虫害发生、制定相应的防御对策及有效评估病虫害造成的损失有重大意义。利用吉林省50个县市的玉米、水稻和大豆产量、面积资料,及相应各站1961-2009年主要病虫害——玉米螟、稻瘟病、大豆蚜资料,根据灾害发生的频数确定病虫害影响指数,分析了各因子的影响程度。通过将各因子极差化处理,计算出综合风险防御指数,对吉林省主要农作物病虫害高、中、低风险防御区进行了区划评估。

| Abstract: | study on risk of crop disease and insect pests has important significance that can defend crop against disease and insect pests,draw up proper countermeasure and evaluate loss induced by pests.Using data of yields and areas of crops(corn,rice and soybean) and insect pests(Corn Borer,Rice Blast,Soybean Aphid,1961-2009)and based on frequency of pests occurrence,yields and areas,the crop disease and insect pests factors were analyzed and the corresponding comprehensive risk defence index was worked out.The are... |
