Doing a good job of planting grapes is one of the keys to achieving early grape yield. Planted grapes are generally grown in the spring and rarely in the autumn. The scientific research and production practice in recent years have consistently shown that the grape planting is better than the spring planting. Where conditions are available, the grapes should be planted in the fall.
First, the benefits of grape planting in autumn
1. Grapes that can be planted in the early fruiting stage and in the high-yield autumn period do not need to slow down the seedlings. The germination growth time is 20-30 days earlier than that of spring planting. Some can bloom in the same year, and the second year will be the general result, while the spring will be The planted grapes could not be flowered in the same year. Only a few plants found fruit in the second year, and they entered the fruiting stage in the third year. The high yield period was one year later than the autumn planting.
2. The survival rate of planting is high. The temperature change in autumn is smaller than that in spring. The humidity of air and soil is higher than that in spring, which is very beneficial to the healing of wounds and the growth of new roots. Therefore, the survival rate of autumn planting grapes is generally up to 90%, which is 20% higher than the survival rate of spring planting.
3. The time for autumn planting is longer than that of spring planting. The time for autumn planting starts from September and ends in October. The time is 45-50 days, which is 15-20 days longer than the spring planting.
Second, grape autumn planting should pay attention to matters
1. Choosing suitable plots and robust seedlings has strong adaptability to soil. Sand, sandy loam, loam, gravel soil, light saline soil can be planted, but sandy loam is best cultivated. In order to improve the survival rate of transplanting and early and high yield, on the basis of selecting strong varieties with cold tolerance, it is necessary to select superior seedlings with developed roots, full buds, no pests and diseases, no mechanical injuries.
2. Fine soil preparation and fertilization, improve the planting quality. After the flattening is selected, the pits are pitted according to the predetermined row spacing. The upper diameter of the pit is 80 cm and the bottom diameter is 40 cm. The roots and shoots of the seedlings should be properly trimmed before planting, and the roots should be preserved as much as possible. Apply 30-40 kg of organic fertilizer and 0.5 kg of urea per pit, evenly spread into the bottom of the pit, backfill 10 cm of soil, plant 1 seedling per pit, fill the soil after compaction, fill the water once, and use soil after water seepage. Level the pit.
3. Strengthen post-planting management 7 days after planting, the soil is kept cold and protected, and the soil pile is about 30 cm thick to protect the seedlings and the seedlings for winter. After the night frost in the coming year, remove the cold-proof mound and pour the water in the right amount. Before germination, cut 2-3 buds; after germination, wipe off the excess buds and pick the hearts of the secondary shoots. When the main tip is 50 cm long, it is topped and then transferred to normal management.
