What are the advantages of transplanting grapes in autumn?
Grapes are rich in nutrients, sweet and juicy, with a unique flavor. Many grape growers usually buy seedlings directly for planting. When transplanting, farmers are most concerned about the survival rate of grape seedlings. In a few months, it will be time for autumn planting of grapes, and many farmers have begun to pay attention to the issue of autumn transplanting of grapes. So, what are the benefits of transplanting grapes in autumn? How to manage?
Advantages of transplanting grapes in autumn
1. We can get results ahead of time.
Grapes transplanted in autumn do not need to delay germination in spring, and the germination time is about 20-30 days earlier than in spring. Some of them can bloom and bear fruit in the same year, and some can bear fruit in the second year. However, grapes transplanted in spring cannot bloom and bear fruit in the same year, only a few plants can see fruit in the second year, and it takes three years to enter the fruiting period, which is one year later than autumn transplanting.
2. High survival rate of grape seedlings.
The temperature fluctuation in autumn is smaller than in spring, and the humidity of air and soil is higher than in spring, which is very conducive to wound healing and new root growth. Therefore, the survival rate of grape transplanting in autumn is generally above 90%, about 20% higher than in spring.
3. Sufficient planting time.
The grape planting time in autumn starts from mid-September and ends in late October, about 45-50 days, which is 15-20 days longer than in spring.
Key points of management for autumn transplanting of grapes
1. Choose suitable land and strong grape seedlings.
Grapes are highly adaptable to soil, and can be planted in sandy soil, loamy sand, loam, gravelly soil, and slightly saline-alkaline soil, with loamy sand being the most suitable. To improve the survival rate of grape transplanting, on the basis of choosing varieties with strong cold resistance, it is necessary to choose good seedlings with developed roots, full branches, free from diseases and pests, and without mechanical damage.
2. Fine land preparation and fertilization can improve planting quality.
After selecting the land, it should be plowed and leveled, and pits should be dug according to predetermined row and plant spacing. The upper diameter of the pit is 80 cm and the bottom diameter is 40 cm. The roots and branches of the seedlings should be pruned before planting, and the roots should be preserved as much as possible. Each pit should be applied with 30-40 kg of organic fertilizer, 0.5 kg of urea, evenly spread at the bottom of the pit, and 10 cm of soil backfilled. Plant one grape seedling in each pit. After filling and compacting, water the pit once. After the water渗透s, promptly cover the soil in the pit.
3. Strengthen post-planting management.
The soil thickness should be about 30 cm, which is beneficial for protecting soil moisture and the safety of seedlings over winter. After the late frost in the second year, it is necessary to clear the cold hills in time and then water moderately. Before the grapes germinate, cut 2-3 buds; after the grapes sprout, remove the extra buds and pinch the secondary branches; when the main branch is 50 cm long, flatten it and then transfer to normal field management.
The above are the advantages and key points of management for autumn transplanting of grapes. According to the growth habits of grapes and weather conditions, autumn is more conducive to the survival of grape seedlings and the growth and repair of roots. I hope the above content can be helpful to grape growers.
