Planting method of grape in greenhouse

Grape is one of the oldest fruit tree species in China, and it is very popular because of its sweet and sour taste. In recent years, grape planting in greenhouse has been increasing. So, what is the planting method of greenhouse grapes?

1. Variety selection

Varieties with high yield, high temperature tolerance, storage and transportation resistance, short dormancy period, short fruit development period, early ripening, moderate growth and disease resistance, such as Jufeng, should be selected.

2. Planting and establishing garden

Some healthy and strong cuttings are required to have more than 20 main and lateral roots, root length more than 15 cm, stem diameter more than 1 cm, and 4-6 full buds. The planting density varies with varieties, site conditions, shaping methods, seedling resources and other conditions. General hedge shaping, the row spacing is 1.2m-1.5m × 0.5m, and about 1000 plants are planted per mu. Before planting, high benefit can only be obtained by applying sufficient base fertilizer and implementing high standard garden. The planting method is the same as the conventional tree planting.

3. Current year management

Shaping and pruning: grape planting in greenhouse is very different from the traditional pruning method because of its high planting density, which is generally used, that is, only one main vine is left after the seedling sprouts.

Strengthen fertilizer and water management: timely topdressing available nitrogen fertilizer to raise seedlings after seedling survival, more phosphorus and potassium fertilizer in autumn, spraying fertilizer on leaves at the same time, pay attention to a small number of times. Base fertilizer was applied early in September. In case of drought in the growing season, water should be watered in time, and pay attention to drainage in the rainy season. In addition, do a good job in the prevention and control of diseases and insect pests.

4. Temperature and humidity management in the shed

Generally speaking, before heating up, the water is poured forward, covered with plastic film to preserve soil moisture, and then heated up. The air humidity in the shed should be controlled at about 90% from mulch to germination, 60-70% from germination to flowering, 50-60% from flowering to fruit expansion, and 50% from later to harvest.

5. Pest control

Grape diseases and insect pests in the greenhouse are relatively light, but can not be ignored, comprehensive control should be carried out, after defoliation combined with winter pruning, cut off disease and insect branches, remove fallen leaves and weeds in the garden, and reduce the overwintering base of diseases and insect pests. The main diseases are house blight, powdery mildew, brown spot, gray mold and so on.

During the period of growing grapes in the greenhouse, due to the different environment and other factors, farmers should adjust measures to local conditions and reasonably control the temperature and humidity.
