Grape harvest management

First, pre-harvest management

1. Trim the ears: First, cut the bottom of the ear with low sweetness, acidity, softness, and easy loss of water in the shrinking fruit. Secondly, dredged grains and granules that are not easy to mature and have poor quality, and at the same time promptly dredged the wounded grains and diseased grains.

2. Potassium Phosphorus and Potassium Fertilizer: Before the harvest, a 0.3% potassium dihydrogen phosphate solution or 0.4% potassium sulfate solution is used for foliar spray. Generally, it is better to spray it twice. This can increase the sugar content and quality of the fruit. Enhance storage stability.

3. Strict water control: In order to ensure the quality of the grapes and improve the storage stability, it is required to strictly control the irrigation within one month before the harvest, and special attention should be paid to the prevention of flooding before the arrival of heavy rain.

4. Preventing cracking: Take measures such as laying grass and covering the surface of the mound to maintain a balanced supply of soil moisture, which can effectively reduce cracking.

5, prevention and treatment of disease: In the fruit coloring, spray once every 10 days or 800 times bacteriocin or 600 times carbendazim solution, in time to prevent the occurrence of disease.

6, spray hormone: in the 15 days before the harvest can be sprayed 2000-4000x 0.000001 than the long or 60-100x 0.000001 of Qingsusu, can effectively prevent the storage process and fruit stem shrinkage.

Second, timely harvest

1. Harvesting standard: The fruit is fully matured, completely browned, and the fruit with full color, fragrance, taste, shape and other characteristics is displayed.

2. Harvest time: If the climate and production conditions permit, the harvest time should be postponed as much as possible. The later harvested grapes, the higher the sugar content, the thicker skin, tough, coloring is also good, fruit powder is fully formed, able to resist storage, harvesting can choose sunny, low temperature early morning or evening picking.

3. Harvesting method: When cutting, carefully cut the ears with scissors, trim the ears, and then put them into boxes or baskets with 3-4 layers of padding. The boxes or baskets can hold about lOkg for the degree and the earrings. Store in a cool place after full set.
