Problems solved by technology

At present, chemical control is the main way to prevent and control spider mites in production. The extensive use of pesticides has led to an increase in the resistance of spider mites. Farmers have blindly increased the amount of pesticides, forming a vicious circle in which the resistance of spider mites gradually increases and the amount of pesticides continues to increase.
What's more serious is that the use of chemical pesticides has also aggravated environmental pollution and affected human health.
[0003] Also studied other methods of preventing infestation now, wherein to utilize a kind of Phytoseiulus similis effect the best, wherein the most used is Neoseiulus similis, but the amount of Neoseiulus similis in prior art is big, every Release 6,000-10,000 heads per mu, release 4-6 times, the cost is high, and the effect is not stable, it is difficult for vegetable farmers to accept, and it is difficult to promote

Embodiment 1

[0024] In a vegetable solar greenhouse in Shouguang, Shandong Province, tomato crops were cultivated in autumn and winter, and the variety was Provence.

[0025] The same solar greenhouse is divided into 7 parts on average, and the middle is isolated with an insect net, and then each part is treated as follows:

[0026] Treatment 1: Make a "concave"-shaped cultivation ridge with a width of 60 cm and a height of 20 cm. The width of the ridge depression is 15 cm, the depth is 8 cm, and the distance between the ridges is 90 cm; 10,000 plants; tomatoes are planted in the depression of the ridge, 2200 plants per mu; after tomato planting, 150 times water solution of Zanthoxylum Enzyme is directional sprayed on the leaves on the day, and 150 times water solution of Zanthoxylum Enzyme is sprayed on the leaves every 20 days, each time per acre of Zanthoxylum bungeanum The dosage of the enzyme is 0.30kg; after the first spraying of the Zanthoxylum bungeanum enzyme dilution, Neoseius pa...

Embodiment 2

[0046] In a vegetable solar greenhouse in Shouguang, Shandong Province, eggplant was cultivated in winter and spring, and the variety was Burita.

[0047] The same solar greenhouse is divided into 7 parts on average, and the middle is isolated with an insect net, and then each part is treated as follows:

[0048] Treatment 1: according to the technical scheme of the present application, specifically: make a "concave" shaped cultivation ridge with a width of 70 cm and a height of 25 cm, a ridge depression with a width of 20 cm and a depth of 10 cm, and a distance between ridges of 80 cm; Sow milk vetch in the whole area, 20,000 seedlings per mu; eggplants are planted in the depression of the ridge, 1,800 plants per mu; after the eggplants are planted, spray 200 times water solution of pepper enzyme on the leaves on the same day, and spray pepper on the leaves again every 30 days Enzyme 200 times aqueous solution, the dosage of Zanthoxylum bungeanum enzyme per acre is 0.20kg eac...

Abstract

The invention discloses a biological control method for spider mites of solanaceous vegetables, which comprises the following steps: making concave cultivation ridges with the width of 60-75 cm and the height of 20-25 cm, wherein the width of the concave part of each ridge is 15-20 cm, the depth of each concave part is 8-10 cm, and the ridge spacing is 80-90 cm; sowing astragalus sinicus at the protruding parts of the ridges 25-30 days before field planting of the main crops; planting main crops in the concave parts of the ridges; directionally spraying a pepper enzyme diluent on leaf surfaces on the same day after the main crops are planted, and spraying once every 20-30 days; after the pepper enzyme diluent is sprayed for the first time, evenly spreading neoseiulus barkeri on leaves of astragalus sinicus, and releasing 6000-10000 neoseiulus barkeri per mu at a time. By adopting the method disclosed by the invention, the release amount of the neoseiulus barkeri can be reduced to 1 / 6-1 / 4 of the release amount in the prior art, so that the production cost is greatly reduced, the agricultural production safety and the agricultural product quality safety are guaranteed, and the ecological environment is protected.

Description

technical field [0001] The invention relates to a method for biological control of spider mites in solanaceous vegetables, belonging to the technical field of vegetable planting. Background technique [0002] Spider mite, spider mite, plant-eating mite of Tetranychidae family (Tetranychidae), takes about 3 weeks from egg to adult. It is one of the most harmful mites that seriously damage vegetables. It has extremely mixed feeding habits and a wide range of host plants. It mainly harms vegetables such as tomatoes, eggplants, and peppers. At present, chemical control is the main way to prevent and control spider mites in production. The extensive use of pesticides has led to the increase of spider mites' resistance. Farmers blindly increase the amount of pesticides, forming a vicious cycle in which spider mites' resistance to pesticides gradually increases and pesticide consumption continues to increase. What's more serious is that the use of chemical pesticides has also aggr...
