Grapes can be planted by cutting when the local soil temperature (15-20cm) is stable above 10℃. In North China, it is from late March to early April, but in mid-April in North China, cutting seedlings can be carried out in the open field.

During the period from cuttage to the generation of new roots, the soil must be prevented from drying. Water it for 10 days, and water it less for clayey soil. Too much watering, too wet soil, low ground temperature and poor ventilation will also affect the rooting of cuttings.

In order to make the branches fully mature, irrigation and fertilization should be stopped or reduced from late July to August, and at the same time, pest control should be strengthened, and the main shoots and auxiliary shoots should be cored to ensure the healthy growth of seedlings and promote the growth of strong seedlings. During the growth of seedlings, it is necessary to plough and weed in time, improve soil ventilation conditions and promote root growth.

Extended data:

Base fertilizer is the most important part of vineyard fertilization, which can be applied in autumn, from grape harvest to soil freezing. However, the production practice shows that the earlier the base fertilizer is applied in autumn, the better.

Base manure is usually applied together with decomposed organic manure (manure, compost, etc.). ) Apply the grapes immediately after harvest, and add some quick-acting fertilizers, such as ammonium nitrate, urea, calcium superphosphate and potassium sulfate.

Base fertilizer has a good effect on restoring tree vigor, promoting root absorption and flower bud differentiation. There are two application methods of base fertilizer: whole garden withdrawal and furrow application, and most of the grapes planted in greenhouse are withdrawn.
