Embodiment 1

[0041] Five tea gardens were selected along the Nanwan Lake in the Xinyang tea area (Table 1), among which three were terraced fields with intercropping forests or tea gardens with trees on the ground, respectively located in Xiaomiao Village, Shisanliqiao, and Madaoling Village, Shihegang and Dongjiahe Qingtang Village; 1 tea garden on flat land with a lot of intercropping trees around the tea garden, located in Chenyu Village, Dongjiahe; 1 tea garden on flat land with a few trees on the ground, located in Xiajiachong Village, Shihegang. In addition, Dongjiahe Qingtang Village and Dongjiahe Chenwan Village are neglected tea gardens. Moreover, Dongjiahe Chenwan Village is near the soil and water conservation project, and there are many ornamental trees and overgrown weeds in the surrounding area. Osmanthus osmanthus trees are intercropped in the tea garden.

[0046] The Overwintering Parts and Damage Regularity of Persimmon Broad-winged Cicada on Osmanthus fragrans

[0047] The overwintering part of the persimmon broad-winged cicada on the sweet-scented osmanthus tree

[0048] The intercropping of tea gardens in Dongjiahe Chenwan Village and the green belt of osmanthus trees planted around it. After investigation, it was found that there were a large number of oviposition marks on the branches of osmanthus trees, so the intercropped osmanthus trees were used as trapping plants to attract persimmons. Adult wax cicadas overwinter to lay eggs.

[0049] figure 1 It is the investigation result of the overwintering and laying eggs of the persimmon broad-winged wax cicada on the branches of sweet-scented osmanthus, among which, figure 1 A in a is one spawning notch covered with white wax filaments on a single branch; b is two spawning scratches covered with white wax filaments on a single branch. The survey found that about 82.86% of t...

[0054] Effects of Intercropping Osmanthus fragrans on the Injury Rate of Tea Branches in Tea Garden

[0055] Select 2 neglected tea gardens in Chenwan Village and Qingtang Village, and 3 conventionally managed tea gardens in Xiaomiao Village, Mazhiling Village and Xiajiachong Village. Among them, there are osmanthus trees intercropped in each row of tea trees in Chenwan Village Tea Garden There are also osmanthus trees planted in the surrounding areas; chestnut trees are intercropped in the tea gardens of Xiaomiao Village (Table 1), and a few ornamental trees are planted in the tea gardens of Mazhiling Village and Xiajiachong Village (Table 1).

[0056] Investigate the effect of oviposition of Cicada persimmoni adults in Chenwan village tea garden with osmanthus tree intercropping and other 4 tea gardens without osmanthus tree intercropping on the damage rate of tea garden branches. After Bayesian discriminant analysis, the results show (Table 2) that the damage rate of tea br...

Abstract

The invention relates to a prevention and control method of ricania sublimbata of tea trees and belongs to the technical field of prevention and control on injurious insects of tea trees. The prevention and control method provided by the invention comprises the following steps: 1) at an adult stage of ricania sublimbata of tea trees, placing luring yellow plates in a tea garden; 2) planting sweet-scented osmanthus trees in the tea garden; 3) on the middle ten days of November every year, cutting off and destroying twigs with eggs on the sweet-scented osmanthus trees; and 4) on the middle ten days of November every year, cutting off and destroying affected tea tree twigs. By adopting green ecological prevention and control technologies, egg lying damage caused by adults of ricania sublimbata to the tea tree twigs can be controlled without any pesticide, the prevention and treatment cost can be reduced, and pollution can be also avoided.

Description

technical field [0001] The invention relates to the technical field of prevention and control of tea tree pests, in particular to a method for preventing and controlling tea tree pests. Background technique [0002] "Xinyang Maojian" is one of the top ten famous teas in the country. It has a long production history and is well-known at home and abroad. It is produced in Xinyang, Henan, so it is named "Xinyang Maojian". In recent years, the rapid development of the "Xinyang Maojian" green tea industry has led to a sharp expansion of the area of ​​tea gardens. Various problems have also emerged in tea garden management, including tea garden construction, variety selection, and pest control. At the same time, with changes in climatic conditions, tea tree cultivation methods, and the ecological environment of tea gardens, the distribution range of the tea tree cicada has expanded year by year, and its damage has increased year by year. It has now become one of the main pests in...
