In the orchard production process, the occurrence of pests and diseases is unavoidable, and modern ecological orchard construction is very cautious for the use of chemical pesticides. How to minimize the threat of pests and diseases on the basis of reducing the number of spraying and the amount of pesticides used is an ecological orchard. The key issues to be considered in the construction. The use of pest and disease survey statistics to conduct scientific surveys of pests and diseases, combined with comprehensive prevention and control methods, can achieve ecological control of pests and diseases in orchards, and achieve the purpose of producing pollution-free fruits. Orchard ecological pests and diseases can not lack the pest survey statistics. If the orchard wants to reduce the number of drugs and control the harm, then it must do the symptomatic medication and scientific medication. The investigation of pests and diseases carried out by the pest survey statistics device is an important part of the prevention and control of pests and diseases. Accurate measurement and reporting of pests and diseases can not only detect the occurrence of pests and diseases in a timely manner, but also can seize the key scientific and pharmaceutical applications during the critical period of prevention and control. To improve the prevention and control effect, maintain the ecological environment of the orchard and the sea, and avoid excessive pesticide residues. In modern ecological orchards, the use of pesticides must strictly follow the results of accurate measurement and reporting. Therefore, the statistical data of pest and disease survey statistics is the most powerful basis for symptomatic use of drugs. As a result of the previous survey of pests and diseases, there is no longer a blind increase in the amount of drugs and the number of prevention and control in the process of controlling pests in the ecological orchards. Early defoliation, control of powdery mildew, silver leaf miner, gold leaf moth, and Diseases and insect pests such as Astragalus membranaceus and Red spider have also been prevented and prevented as soon as possible. Not only the fruit trees have a good growth state, but also the fruit quality is high and the quality is good. It not only meets the purpose of pest control, but also meets the requirements of ecological and environmental protection. The application of pest and disease survey statistics is one of the key technologies for the production of high-quality green fruits in many orchards, and it is also one of the effective measures for promoting the reduction and control of pesticides in agriculture. The effect is outstanding in practical applications, so it should be vigorously promoted and applied.
