Grape greenhouse planting technology:
1, variety selection
Grape planting need to choose early maturity, high sugar content varieties. At the same time to choose a strong resistance to disease in line with local soil conditions and climatic factors of the varieties, in order to ensure that the grapes can be picked in a timely manner after maturity and made into a variety of products.
2, greenhouse location selection
Grape planting yield and quality and greenhouse location has a great relationship, location selection should be scientific and reasonable, to be able to give the grapes grow sufficient light. At the same time to be next to the water source, one is conducive to irrigation; two is conducive to drainage. In addition to choose the soil nutrient-rich, soil permeability plots, to ensure that the harvest of grapes with sufficient moisture and good taste.
3, seedling cultivation
In the cultivation of seedlings, to north-south cultivation, the purpose is to make the grape growing process of light evenly, so that the greenhouse ventilation is good. Seedling plant cultivation distance is about 45cm in row spacing, the purpose is to facilitate daily pruning and mechanical operations. After the seedlings are planted, the planting pit should be stepped evenly, so that the rootstock of the grapes is flush with the ground, in order to facilitate the later plots of cultivation.
4, pruning and shaping
In the process of viticulture, the plant should be timely pruning of branches and leaves, in order to avoid the new growth of lateral branches affect the main branch nutrient absorption. In winter, pruning is probably carried out at the beginning of February, pruning the main branch first to implement protective measures to avoid injury to the main branch. When the branch of the grape plant grows to 8cm, it should be repaired, and the excess branches will be cut off, leaving only the main branch.
5, flower and fruit management
In order to ensure that the high quality of grapes and high yield, in the pollination period can be pollinated to ensure that the grapes are pollinated smoothly. Artificial pollination can be carried out using a pollination brush made of rabbit hair to enhance the yield of grapes. During the flowering and fruiting period, the clusters can be trimmed to remove excess clusters and retain robust clusters. In the grape berries grow to 1cm, it is necessary to manage the fruit, stay big fruit, remove small fruit disease fruit.
6, fruit bagging
In order to avoid the grape fruit by insects and other bites, in order to avoid the grape fruit by insect pests, in order to ensure that the grapes smooth surface, color and lustre bright, you can use the plastic film paper for bagging treatment. The bagging time of grapes is generally one month after flowering, grape fruit results about 1cm when carried out. Bagging is generally carried out in the morning or evening, can not be carried out at noon, in order to avoid high temperatures in the middle of the day, the bag accumulates too high a temperature, is not conducive to the growth of grape fruit.
7, shed temperature debugging
In order to ensure that the grape growth process of light, you can improve the shed light conditions. By changing the color of the wall in the shed to extend the light time. Regulate the temperature in the shed, the growth of grapes has an important role. Grapes have different temperature needs at different stages of growth, and growers can debug the temperature in the shed according to the temperature needs of grapes. The use of insulation quilt or grass cover can be used to increase the temperature of the shed, can be ventilated, sprinkler, etc. to reduce the temperature of the shed, but also to carry out the control of the humidity of the shed and the control of the shed gas.
8, water and fertilizer management
Grapes in the growth process of water demand is very large, generally in the planting of grapes in the formal planting before digging a good depth of 80cm, 100cm wide ditch for soil irrigation, with the application of organic fertilizer. When the grape plant grows to about 30cm high, the need for fertilizer treatment, fertilizer is mainly in the bud before the pursuit of nitrogen fertilizer, fruit after the pursuit of nitrogen fertilizer and phosphate fertilizer, potash, the purpose is to improve the sweetness of the grape fruit. The process of grape growth should be about 3 times of irrigation, one irrigation during the budding period, one irrigation during the fruiting period, and one irrigation before sealing the soil in winter.
