Autumn harvest of grapes is more beneficial than spring cultivation
In the past, planting grapes was generally in the spring and autumn was rarely planted. Recent scientific research and production practices have shown that the autumn planting of grapes is better than planting in spring. There are four main benefits of planting grapes in the autumn than in spring: First, they can provide early results. Grapes planted in autumn do not need to be seedlings in spring, and the germination time is 20-30 days earlier than that of spring plants. The grapes planted in the spring can't bear fruit in the same year. Only a few plants can see the fruit in the second year, and can enter the fruiting period in the third year. The high yield period is one year later than that in autumn. The second is the high survival rate of planting. The change in temperature in autumn is smaller than that in spring. The humidity in air and soil is greater than that in spring, which is very favorable for wound healing and new root growth. Therefore, the survival rate of autumn grapes is generally more than 90%, which is about 20% higher than the survival rate of spring plants. The third is that the autumn plant has more time than spring planting. The time for the grapes to be planted in autumn begins in mid-September and ends at the end of October. The time is as long as 45 to 50 days, 15 to 20 days longer than the spring planting time. The fourth is to avoid competing with crops such as grain, cotton, and oil for water and fertilizer, which will help satisfy the demand for water and fertilizer in autumn grapes, and ensure the quality of the autumn grape planting. In order to improve the effect of the autumn harvest of grapes, the following points should be paid attention to in the management of planting and post-planting: Selecting suitable plots and robust seedlings The grapes are highly adaptable to the soil, sandy soil, sandy loam, loam, gravelly soil Alkaline soil and light saline soil can be planted, but sandy loam soil is the most suitable and sandy soil plots should be planted as far as possible. In order to improve the survival rate of transplanted grapes and achieve high yield, based on the selection of varieties with strong cold tolerance, excellent seedlings with well-developed root system, complete branch buds, no pests and diseases, and no mechanical damage should be selected. Fine soil preparation and fertilization, improvement of planting quality, selection of plots, ploughing and leveling, digging of pits by predetermined line and spacing, pit diameter of 80 cm, bottom diameter of 40 cm. Before planting, properly trim the roots and shoots of the seedlings. The root system should be kept as much as possible. Apply 30-40 kg of organic fertilizer and 0.5 kg of urea to each pit. Spread it evenly into the bottom of the pit and backfill 10 cm of soil. Each pit is planted with a grape seedling. After the soil is compacted, it is filled with water once. After the water penetrates, the pit is covered with soil in time. Strengthen the post-planting management. The piles should be cold-proofed and preserved at about 7 days after planting. The thickness of the mound is generally about 30 cm in order to facilitate the safe wintering of the soil and seedlings. After the frost blooms in the coming year, we will take a pile of anti-cold soil in due course, and pour the water in suitable amount. Before the sprouting of the grapes, 2 to 3 buds were cut off; after the buds of the grapes, the excess buds were touched and the tips were picked up; when the main shoots were grown to 50 cm long, the hearts were picked and later transferred to normal field management.
