植保专业基础数字的统计标准化,是当前急待解决的问题。长期以来,植保部门积累了农作物病虫害的发生面积、发生程度、防治面积、挽回损失和实际损失等大量数据,但由于没有统计标准,影响了资料的科学性、可比性和应用价值。农作物病虫害发生程度过去多属单一病虫害进行统计,缺乏以作物为单位的多种病虫害发生程度的综合指标,因而很难测定农作物病虫危害减产损失。实现统计标准化,将数据输
The statistical standardization of the basic figures of plant protection professionals is an urgent issue to be solved. For a long time, the plant protection department has accumulated a large amount of data such as the occurrence area, degree of occurrence, area of control, loss recovery and actual losses of crop diseases and insect pests. However, the absence of statistical standards has affected the scientificity, comparability and application value of the data. In the past, the incidence of crop pests and diseases were mostly single pests and diseases statistics. The lack of a comprehensive index of occurrences of various pests and diseases on the crop basis makes it difficult to determine the loss of crop and pest damage reduction. To achieve statistical standardization, the data lost
