Problems solved by technology

[0004] One of the important differences between pak choi and other vegetables is the short growth period, especially for pak choy in summer, it only takes more than 20 days from planting to harvest. If the control of cabbage caterpillar is not effective, it will cause serious losses
If pesticides are used for control, the short application interval will cause a large amount of pesticides to remain in the vegetables, causing major hidden dangers to human health.
Although the agricultural control of cabbage caterpillar has also been reported, most of them have not been popularized because of poor effect or too much labor.

Embodiment Construction

[0018] A vegetable bed is 9m long and 2m wide, and a membrane grid is built on it to grow Chinese cabbage and prevent the damage of cabbage caterpillars. The steps are as follows:

[0019] (1) Binding support frame: Nail the vertical pole 1 around the long vegetable bed, tie the horizontal bar 2 on the top of the vertical pole 1; nail the vertical pole 1 horizontally at intervals of 3m in the longitudinal direction of the vegetable bed, and tie the horizontal bar 2; The height of the support frame is 80cm.

[0020] (2) Binding enclosure film 3: Take a plastic film with a width of 1m, and form a circle around the support frame around the vegetable bed. The upper part of the film is bound on the cross bar 2, and the lower part is buried in the soil; Bind the plastic film on the supporting frame in the same way, and divide the vegetable bed into 3 membrane grids separated by plastic film with length × width of 3m × 2m ( figure 1 ).

[0021] (3) Sowing management: Sow purple cab...

Abstract

The invention discloses a method for preventing pakchoi from attacks by cabbage caterpillars. According to the invention, a vegetable garden is separated into small film grids by using a supporting frame and a plastic film, and pakchoi is planted in the small film grids; the sight of Pieris rapae is blocked in virtue of the thin film so as to prevent Pieris rapae from laying eggs on pakchoi and attacking pakchoi. The method has the advantages of pesticide-free process, easiness, low cost, obvious effects and easy popularization.

Description

technical field [0001] The invention relates to the technical field of pakchoi plant protection, in particular to a method for preventing cabbage from being harmed by cabbage caterpillars. Background technique [0002] Chinese cabbage (Brassica rapa L. Chinensis Group.) is also known as green vegetables and rapeseed. Brassica genus Brassica, which has rich nutrition and high food value, is one of the important vegetable foods in people's daily life. [0003] Cabbage caterpillar is the larva of Pieris rapae Linne, belonging to Lepidoptera, Pelicidae. Pieris rapae is one of the important pests in the production of Chinese cabbage, and it occurs all over the country. Its larvae gnaw on the green leaves of cabbage, and at the slightest, bite the leaves, leaving holes or nicks, reducing the yield of cabbage and destroying the appearance of the cabbage; The sinking caused serious losses to production. At present, the main method of its prevention and control is to use pestic...
