Abstract
Experiments were designed to scientifically evaluate the contribution of plant protection in wheat and corn produc-tion in Pucheng County.Strict control areas,unified control areas,farmers'self-control areas and blank control areas were set up.A diagonal 5-point sampling survey method was used to investigate the occurrence of diseases,insect pests and weeds after weed removal during the wheat return green period and during the filling period,and to investigate the occurrence of diseases,insect pests and weeds during the entire growth period of corn;Theoretical and actual yield tests are carried out during the mature period of wheat and corn,and the yield per mu,losses recovered,plant protection contribution rate,etc.under different control levels are calculated.County plant protection contribution rate is calculated based on the proportion of sampled representative area in the county's planting area.The results show that plant protection can effectively control the occurrence of diseases,insect pests and weeds in wheat and corn,and the types and degrees of diseases and insect pests in wheat and corn are significantly reduced.Through calculation,the contribution rate of plant protection in wheat production in Pucheng County is 20.56%;the contribution rate of plant protection in corn production is 23.5%.关键词
