The total area of ​​farmland is more than 4,000 hm2, including 1154 hm2 of tea gardens and 263 hm2 of cultivated land. In recent years, Zhaodong Reclamation Area has played a key role in the prevention and control of tea pests from the aspects of tea control and physical control, protection and use of natural enemies, and chemical control through tea plants as the main body and tea plantation environment as the basis. Significant results have been achieved. The prediction of pests and diseases in the farming area can be measured and reported using solar energy pest report lamps.
In the process of tea picking, the upper leaves of the tea leaves are removed, and some eggs can be taken away to reduce the degree of harm. According to different tree ages and different tree vigors of tea trees, different pruning methods were used to prune tea trees to cultivate and expand the canopy and rejuvenate the tree vigor. Keep 20cm distance between tea rows, which is conducive to tea garden operations, increase ventilation and light transmission, and reduce the occurrence of pests. A certain amount of vegetation should be kept around the tea plantation. For tea gardens where the natural ecological conditions are not very good, trees and grass are used to increase the number of tea plantations, and shelter forests and street trees are planted to provide good habitat and reproduction for natural enemies and beneficial organisms. Conditions; to change the concept of “see pests and treat diseases and treat insect pests and netsâ€; biological pesticides should be used as far as possible for prevention and control; promote the use of plant and microbial source pesticides such as matrine and Beauveria bassiana; Predators of tea tree pests can also stock chickens in Chashan; due to the low quality of fresh leaves in summer and summer seasons, the tea produced is mostly middle and low-grade tea. In order to increase the yield of fresh leaves in spring and autumn and improve the quality of tea, less or less No summer, summer tea. At the same time, many major natural enemies of tea trees are also in this period. Therefore, besides weeding in the summer and summer seasons, the tea gardens should minimize the agricultural activities in the tea gardens, strive to create a good environment for the activities of tea trees and natural enemies, and use the prevention and control capabilities of natural organisms to ensure that they fall short of cultivation. The application of solar energy pest forecast lamp is to utilize the phototaxis and chemotaxis of tea tree pests, and kill them with mechanical and artificial killing, as well as insecticidal lamps and insect traps.
Grasp the prevention and control standards, use the statistics of solar energy pests to report the number of lamps to predict the status of the disease, accurately grasp the occurrence of pests and natural enemies peak period, to provide scientific basis for the prevention and control of pests and the protection of natural enemies. When tea pods appear spotted in the tea garden, if the tea pods are in the majority, they must be treated with chemicals. Camellia elegans was used at the end of adult excavation, and scale insects and whiteflies were used during the final period of egg hatching, and corresponding measures were taken for prevention and treatment.
