[0010] Example 1 Attractive effect of chestnut leaves on the natural enemies of Leafhopper chrysalis

[0011] 1 Materials and methods

[0012] Using a Y-shaped olfactory instrument to measure the smell of chestnut leaves has a significant impact on the spiders that prey on the leafhopper (Three-protruded spider, white-spotted spider) and the parasitic wasps that parasitize the leafhopper's eggs (Leafhopper three-clawed wasp, micro-cracked wasp ) of the lure effect.

[0013] The base end of the Y-shaped olfactometer and the length of both arms are 10cm, and the angle between the two arms is 120°. The base is connected to an air pump for air extraction, and each arm is connected to a humidifier, a taste source bottle (or CK bottle), an activated carbon filter, and a flow meter in turn. Put fresh chestnut leaves in the flavor source bottle; the other arm is the CK arm, and no flavor source is placed in its CK bottle, that is, air is used as a control.

[0021] Example 2 Differences in the population of Leafhopper spp. in tea gardens with 4 kinds of chestnut intercropping densities

[0022] 1 Materials and methods

[0023] In the tea area of ​​Songyang County, Zhejiang Province, several intercropping methods were selected in which the tea tree varieties were all Wuniuzao, and the distance between the bottom of the chestnut canopy and the tea canopy surface was 1.5m: ① chestnut row spacing 4.5m, plant spacing 4.5m; ② chestnut row spacing 6.0m, The row spacing of chestnuts is 6.0m; ③The chestnut row spacing is 9.0m, the row spacing is 9.0m; ④The chestnut row spacing is 10.5m, and the row spacing is 10.5m. The area of ​​each tested tea garden is 10 mu.

[0024] From mid-May to mid-October in 2015, the population of Leafhopper with false eyes in tea gardens was investigated every ten days. Each survey was completed before 9:00 in the morning when the dew was still wet. In the tea garden of each intercropping method, 10 points w...

[0029] Example 3 Differences in the population of Leafhopper with false eyes in tea gardens with different distances from the surface of the tea canopy to the bottom of the chestnut tree canopy

[0030] 1 Materials and methods

[0031] In the tea plantation of Jingting Mountain in Xuancheng City, Anhui Province, the tea tree varieties are all Fuding Dabai tea, and the chestnut trees are intercropped in several ways in the tea garden with a row and plant spacing of 6.0m: ①The distance from the bottom of the chestnut crown to the canopy of the tea tree is 1.0m;② The distance is 1.5m; ③The distance is 2.0m; ④The chestnut is not intercropped in CK area. The area of ​​each tested tea garden is 10 mu. From mid-May to mid-October in 2016, the population of Leafhopper with false eyes in tea gardens was investigated once every ten days, and the investigation method was the same as "Example 2".

Abstract

The invention provides a method for restricting tea garden empoasca vitis Gothe by intercropping Chinese chestnut trees. Intercropping Chinese chestnut trees in a tea garden where plantation is in strips; the Chinese chestnut trees are planted among the tea rows according to certain density; proper distance is kept between a bottom of the Chinese chestnut crown and the tea tree canopy surface. This method facilitates the climbing, transfer and foraging of the natural enemies of the leafhoppers, thereby strengthening the natural control of natural enemies on the leafhoppers. The use of chemicalpesticides to control the frequency and dosage of the leafhoppers can be reduced or exempted, which will help protect the environment and ensure the quality and safety of tea leaves.

Description

technical field [0001] The invention belongs to the field of plant protection, and relates to planting chestnut trees in the middle of tea gardens planted in strips, attracting natural enemies with the smell emitted by the chestnut trees and the tree shape of the chestnut trees, thereby restricting the important pests in the tea garden, the small green leafhopper with false eyes, and reducing damage to the leaves. Pesticide control of cicadas. Background technique [0002] The area of ​​my country's tea gardens is 43.2 million mu, accounting for almost 60% of the world's tea gardens. Empoascavitis It is the most important pest widely distributed in tea gardens in mainland China. It pricks and sucks the young leaves and shoots of tea trees, causing the tea leaves to be reddish brown and scorched. It also lays eggs under the cortex of young shoots, hindering the production of photosynthetic products, water and mineral elements Normal conduction in the body. Usually this pes...
