Problems solved by technology

[0002] At present, grapes grown in greenhouses are generally flat and horizontal. Due to the high temperature and humidity microclimate formed by protected cultivation, it provides favorable conditions for the occurrence of grape diseases. Botrytis cinerea often causes a large number of flowers and fruits to rot, and the diseased fruit rate of susceptible varieties It can reach 30% to 60%, which has a great influence on the yield and quality of grapes

Embodiment Construction

[0010] A control method for botrytis cinerea. At first, the following requirements should be noted before the control: 1. The use time of vegetable and fruit strengthening base should be in the early stage of flowering, the stage of flowering and fruit setting and before watering. 2. The preparation tools include vegetable and fruit seedling spirit, ridge digger, plastic film, thermometer, and hygrometer.

[0011] Prevention steps are as follows:

[0012] Step 1: Take an appropriate amount of vegetable and fruit strong base spirit, mix each portion with 15 kg of water, and spray it on the grapes in the early flowering stage, flowering and fruit setting stage, and before watering;

[0013] Step 2: Excavate the land in the greenhouse into a high ridge with a ridge width of 55 cm, a ditch depth of 35 cm, and a ditch width of 25 cm by using a ridge digger or manually. When planting, plant 2 rows per ridge with a plant spacing of 15 to 18 cm. cm;

[0014] Step 3: Cover all the pl...

Abstract

The invention relates to and provides a prevention and control method of grape gray mould. The method adopts a high-ridged cultivation method to reasonably perform close planting, can improve the ventilation, sprays pesticide for prevention and control at the earlier stage of flowering period, during blossom and fruit bearing period and before watering, improves the grape circulating fruit setting rate by spraying plant base strengthening agent, promotes fruit development, focuses on protecting flower and fruit, coordinates nutrient balance, increases the earth temperature and reduces the relative air humidity by adopting a mulching film for covering, meanwhile can prevent fruit from directly contacting with soil, thereby reducing the opportunity of pathogenic bacteria invasion, and is relatively low in the cost.

Description

technical field [0001] The invention relates to a method for preventing and treating grape scab. Background technique [0002] At present, grapes grown in greenhouses are generally flat and horizontal. Due to the high temperature and humidity microclimate formed by protected cultivation, it provides favorable conditions for the occurrence of grape diseases. Botrytis cinerea often causes a large number of flowers and fruits to rot, and the diseased fruit rate of susceptible varieties It can reach 30% to 60%, which has a great influence on the yield and quality of grapes. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a control method capable of preventing gray mold of grapes in advance and improving grape yield. [0004] In order to solve the above-mentioned technical problems, the invention provides a physical control method of botrytis cinerea, which can also reduce the use of pesticides while ensuring the con...
