1, seedling selection: the selection of grape seedlings is directly related to the fruit setting rate of grapes in the future, so when selecting seedlings, we should choose strong seedlings with developed roots, relatively complete preservation, no pests and diseases and relatively full embryos. Then the selection of seedlings also needs to be combined with the local climate characteristics to choose grape seedlings suitable for growth. In addition, according to personal experience, if you are an old grower, you can choose seedless grapes with good appearance and sweet taste that are not easy to cultivate.

2. Treatment of grape seedlings: After the grape seedlings are selected, they need to be pruned accordingly. After pruning, more than three full buds should be left on the grape seedlings, and then the lateral roots should be cut short to keep the root length about 15cm. Then, the pruned grape seedlings should be soaked in clear water for one day, so that the seedlings can fully absorb water and be disinfected before planting.

3. Planting time: The season suitable for planting grape seedlings is spring, and it is usually planted during the period from fright to vernal equinox. If it is planted in the open air, it is necessary to build a shed in advance to shelter from the wind and rain. Pay attention to plant spacing and row spacing when planting, and water according to the actual situation.

4. Cover with plastic film: In order to keep out the wind and rain when planting, black plastic film is usually chosen to cover the greenhouse. The main purpose of plastic film mulching is to maintain the temperature and humidity of the ground, but also to reduce the growth of weeds and improve the growth rate of grapes. After planting grape seedlings, we should always check the survival of the seedlings. If any grape seedlings don't survive, we need to replant them in time.

5. Fertilization: Top dressing starts about half a month after the grape seedlings germinate. Generally, at this time, the grape seedlings grow 7-8 new leaves and tendrils, and topdressing can be carried out at this time. In the early stage of topdressing, nitrogen fertilizer was mainly used to promote the growth of grape seedlings and accelerate plant formation. However, attention should be paid to the concentration of fertilizer when applying fertilizer, otherwise it will easily cause seedlings to burn and damage the roots. Water in time after fertilization. However, it is necessary to control the vigorous growth of grapes after they grow. At this time, we should stop using nitrogen fertilizer and start using appropriate amount of potassium fertilizer and phosphate fertilizer.

6. Watering to prevent insects: keep the soil moist when the grape seedlings are planted, and reduce the number and amount of watering during the growing period. The pests and diseases that need to be prevented in the early stage are scarab, green blind stinkbug and black pox, and the occurrence of downy mildew needs to be prevented in the later stage.
