Grapes cultivated in temperature and humidity management greenhouses have entered flowering and fruit setting period. At this time, the process of flowering and pollination of grapes needs higher temperatures. The daytime temperature should be controlled at about 28°C, and it should be kept at 15°C to 18°C ​​during the night. Appropriately increasing the night temperature during young fruit enlargement is beneficial to the increase of fruit size. The humidity during fruit expansion should be controlled at 50% to 70%, which will help reduce the disease.

The vines manage the shed grapes to do a secondary tip processing. The top axe shoots leave 3 to 5 leaves repeatedly topping the heart. The other axillary shoots above the inflorescence are treated with a single leaf method. All the other tips are wiped to ensure a single shoot function leaf. Not less than 20 tablets.

Sparse Sprue Grapes Spikes are generally carried out after the flowering young fruit begins to swell. In accordance with the characteristics of the variety and the fruit-retaining standard, a tip is generally reserved. Grape spalling work is carried out during the fruit enlargement period. Large grains and large ear types (such as Rizamat) have left about 80 grains per panicle, and large grain panicle types (such as Kyoho and Fujisawa) have left about 40 grains per panicle. The middle panicle type (such as giant rose, summer black, etc.) left about 60 grains per panicle, and the small spike small fruit type (such as joy) left about 80 grains per panicle. Spalling is ended, and the low-concentration insecticidal bactericidal mixed medicament is used after bagging.

Pest control 1. Black pox disease: 50% Prochloraz Manganese Emulsion 1000 times spray control, can be an anthrax. 2.

Pieris rapae: adult emergence, larval incubation period with 25% diflubenzuron suspension 2000 times or 2.5% lambda-cyhalothrin EC 2000 ~ 3000 times, spray 2 or 3 times. The young fruit period strictly controls the concentration of the drug.
