1, variety selection
Grape planting needs to choose varieties with early maturity and high sugar content. At the same time, it is necessary to choose varieties with strong disease resistance and in line with local soil conditions and climatic factors, so as to ensure that grapes can be picked in time after maturity and made into various products.
2, greenhouse site selection
The yield and quality of grape planting have a great relationship with the location of greenhouse. The site selection should be scientific and reasonable, and the grape growth should have sufficient light. At the same time, it should be next to the water source. First, it is beneficial to irrigation; Secondly, it is beneficial to drainage. In addition, it is necessary to choose plots with rich soil nutrients and strong soil permeability to ensure that the harvested grapes have sufficient water and good taste.
Step 3 raise seedlings
When planting seedlings, we should cultivate them in the north-south direction, so that the grapes can grow evenly and the greenhouse can be well ventilated. Seedling spacing is about 45cm, which is convenient for daily pruning and mechanical operation. After the seedlings are planted, the planting pits should be stepped evenly so that the roots of the grapes are flush with the ground, which is beneficial to the later land cultivation.
4. Dressing and shaping
In the process of grape cultivation, the branches and leaves of the plants should be pruned in time to avoid new lateral branches affecting the nutrient absorption of the main branches. Pruning will be carried out in early February in winter. When pruning, first protect the main branches so as not to hurt them. When the branches of grape plants grow to 8cm, they should be repaired, cut off the redundant branches and keep only the main branches.
5. Flower and fruit management
In order to ensure high quality and high yield of grapes, artificial pollination can be carried out during pollination to ensure smooth pollination of grapes. The pollination brush made of rabbit hair can be used for artificial pollination to improve grape yield. During the flowering and fruiting period of grapes, the ear can be pruned to remove the redundant ear and keep the strong ear. When the grape fruit grows to 1cm, it is necessary to manage the fruit, keep the big fruit and remove the diseased small fruit.
6, fruit bagging
In order to prevent the grape fruit from being bitten by insects, prevent the grape fruit from being damaged by pests, and ensure the smooth surface and bright color of the grape, plastic film paper can be used for bagging. The bagging time of grapes is generally one month after flowering, and the grape fruit is about 1cm. Bagging is usually carried out in the morning or evening, not at noon, to avoid high temperature at noon and high temperature accumulation in the bag, which is not conducive to the growth of grape fruits.
7. Temperature debugging in the shed
In order to ensure the illumination during grape growth, the illumination conditions in the shed can be improved. By changing the color of the wall in the shed, the lighting time can be extended. Adjusting the temperature in the greenhouse plays an important role in the growth of grapes. Grapes have different temperature requirements at different growth stages, and growers can adjust the temperature in the shed according to the temperature requirements of grapes. The temperature in the shed can be improved by covering with heat preservation or grass, and reduced by ventilation and sprinkling, and at the same time, the humidity and gas in the shed should be controlled well.
8, water and fertilizer management
Grapes need a lot of water during their growth. Generally, before planting grapes, ditches with a depth of 80cm and a width of 100cm will be dug for soil irrigation and organic fertilizer will be applied at the same time. When grape plants grow to a height of about 30cm, topdressing is needed. Topdressing mainly means topdressing nitrogen fertilizer before germination and nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer after fruit setting to improve the sweetness of grape fruits. During the growth of grapes, it takes about three times of irrigation, once in the germination stage, once in the fruit-setting stage and once before sealing the soil in winter.
