Method for improving pest and disease damage resistance for pear planting

Abstract

The invention discloses a method for improving pest and disease damage resistance for Dangshan pear planting. The method comprises the following steps that pyrethrum is subjected to annular interplanting under a pear tree, the area takes the pear tree as the center, the radium ranges from 10 cm to 12 cm, and the outer ring width ranges from 15 cm to 20 cm; mature fruits are protected through a liquid membrane, the liquid protection membrane is prepared from water, a Kangjie plant membrane stock solution, nanocellulose, monoglyceride, celangulin, eugenol and traditional Chinese medicine liquid; a prepared protection membrane solution is used, after the pear tree bears fruits, the protection membrane solution is sprayed once every 10-12 d, and in the final stage of fruit maturity, the protection membrane solution is sprayed once every 5-7 d; in soil which takes the pear tree as the center and is within the circular range that the radium ranges from 6 cm to 8 cm, the hole digging depth ranges from 10 cm to 12 cm, 0.4%-0.6% by mass of thiophanate-methy and 0.5%-0.7% by mass of pyrethrum are used for preparing a mixed solution with the proportion being 1:1, 2-3 L of the mixed solution is irrigated in a pit, the control pit is filled up with the soil, covering is conducted through a plastic film thin film, soil covers the membrane, and compaction is conducted.

Description

technical field [0001] The invention belongs to the technical field of Dangshan pear planting, and in particular relates to a method for improving the resistance to plant diseases and insect pests of Dangshan pear. Background technique [0002] Dangshan has a long history and culture, and Dangshan pears have a 3,000-year cultivation history. As early as Ming Wanli's "Xuzhou Fuzhi" has been recorded that "Dangshan produces pears". Dangshan crispy pear contains sugar, minerals, organic acids and multi-vitamins, and is rich in nutrition; Dangshan crispy pear is sold in domestic and foreign markets for its large fruit, bright yellow color, thin and juicy skin, multi-core meat and small, sweet and crisp. , has become a rare good product in my country's fruit products.

Problems solved by technology

[0003] However, during the planting of Dangshansu pears, pear trees are vulnerable to damage by diseases and insect pests. The ripe fruit has thin skin and high sugar content, and is also more likely to be infested by harmful microorganisms and pests, which affects the cultivation of Dangshansu pears.

The problem of pests and diseases in the planting process of Dangshansu pear, because the traditional planting of Dangshan pear adopts a single planting method, the planting structure is simple, and the ability to prevent external damage is poor; the method of spraying fungicides and pesticides, the utilization rate of drug components is low, and there is a risk of pesticide residues; Using traditional fruit paper bag bagging and liquid film spraying, the retention time is short, the air permeability is poor, and it does not contain antibacterial and insecticidal ingredients, and the bactericidal and insecticidal effects are poor
