Theoretically speaking, grape seedlings can be planted from the time they drop their leaves until they sprout in the following spring, as long as the temperature and soil conditions are suitable, so the planting period is relatively long. However, in production practice, it is mainly cultivated in spring and autumn. Northern my country has cold winters, so spring planting is mostly used, while autumn planting is mostly used in central and southern regions.
Spring planting should be carried out after the soil thaws. In areas with cold winter and deep frozen soil, it is best to plant in spring when the soil temperature at the root layer reaches 7~10℃, such as a large garden area. Or when the labor is tight, it can also be appropriately advanced. When planting in spring, firstly, we must pay attention to using measures such as covering and frequent irrigation to prevent spring drought; secondly, we must pay attention to the right time and never delay planting until the seedlings sprout. This will not only easily bruise the young shoots, but also have a great impact on the survival and growth of the seedlings. big. Due to the dry and windy spring, the garden planted in spring must have irrigation conditions.
Autumn planting is usually carried out in October. The survival rate of the seedlings after planting is high. The root system can resume growth that year and can grow some new roots. It can absorb water and nutrients in the soil early. As soon as spring begins in the second year, the seedlings can start to grow rapidly, which is beneficial to early germination, early growth, early formation, early fruiting, and early high yield. Judging from the growth conditions after planting, autumn planting is most suitable in northern areas where winter temperatures are slightly warmer, but it must be buried in the soil to survive the winter.
If you use plastic bags to quickly raise seedlings, transplant them with leaves in mid-to-late May. Especially in arid areas, the seedling planting period in nutrient bags avoids the windy and drought period in late spring, playing a role of "nurturing instead of planting" Effective, the survival rate is very high. However, when planting, you must pay attention to planting with nutritious soil and prevent the land from loosening. Water immediately after planting and pay attention to proper shading and covering.
There is also one that is planted in winter, from late December to late January of the following year. It is usually planted before the beginning of the year. It is mainly suitable for the south. Relatively speaking, the survival rate is low.
