Embodiment

[0024] Embodiment: the control method of this bagged apple black spot disease comprises the following contents:

[0025] (1) Increase the application of bio-organic fertilizer and medium-trace element fertilizer, apply 500 kilograms of bio-organic fertilizer per mu after picking fruit, and 100 kilograms of medium-trace element, adopt the method of radial ditch application;

[0026] (2) Do not apply nitrogen, phosphorus, and potassium compound fertilizers;

[0027] (3) Cover the tree with grass, evenly cover the crop stalks or weeds with a thickness of about 25 cm within the projection range of the tree crown, and cover the whole year;

[0028] (4) Spray the pesticide tincture made of Chinese herbal medicine before and after the flowering period, that is, take 550g of Hibiscus bark, 350g of Baibu, 750g of Coptis chinensis, 250g of star anise, and 400g of Moutan bark. , add an appropriate amount of ethanol, cover and impregnate, stir, and after standing for 5 days, pour out the...

Abstract

The invention discloses a method for preventing and controlling the black-dot disease of bagged apples. The method is a biological comprehensive prevention and control method which mainly uses Chinese herbal medicine tincture. The method comprises the steps of applying bio-organic fertilizer and medium-trace element fertilizer without applying nitrogen-phosphorus-potassium compound fertilizer, uniformly covering crop straws or weeds with thickness of 25 centimeters in a crown projection range all the year, and spraying pesticide tincture prepared by cortex pseudolaricis, radix stemonae, rhizoma coptidis, illicium verum and moutan bark in a flowering phase. The preventive rate can reach 96.7% through field trial, no pesticide is remained, the preventive and control cost is low and the method is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of prevention and control of fruit tree diseases and insect pests, in particular to a method for preventing and treating black spot disease of bagged apples. Background technique [0002] Apple bagging can significantly reduce the damage of diseases and insect pests, improve fruit coloring, improve the smoothness and appearance quality of fruit surface, and is one of the important technologies to improve the economic benefits of apples. To the expected effect. But at the same time, various places have successively found that black spot disease is very prone to occur on the fruit surface after bagging. After the onset, not only the appearance is not improved by bagging, but the defects of the fruit surface are increased. Through the experimental research of fruit tree science and technology workers and fruit growers, the mechanism and control methods of black spot disease have been clarified. Its symptoms, ...
