Summer grape seedlings

Grape cuttings in the summer, can be nursery in the fall of the year, is an effective way to shorten the nursery cycle. It has the advantages of short time for seedlings, high survival rate, reduced winter storage process and investment, good seedling quality, strong growth, and good economic benefits. 1. Rod insertion time: 6-8 months. When the new vine was grown to 5 to 10 knots, it was the best time for cutting. 2. Slotting preparation. The seedbed requires good lighting, convenient drainage and irrigation, loose and fertile soil, and tillage tillage and leveling. It is built into 1 to 1.2 meters wide slotted plugs (3 to 4 rows, 6 to 8 cm spacing). At the same time, stand and branches are prepared for shading. 3. Cutting operation. The cuttings should be selected from vines that have been lignified and their buds are yellow-brown, cut into small pieces 20 to 25 cm long (with 3 to 5 knots), leaving 1 leaf at the tip of the cuttings, and the other leaves are cut off along with the petioles and the shoots from the bottom After the cuts are cut into horse ears, the cuttings are cut and inserted into the seedbed in time, pouring enough water and putting the shed in place. The arbor is 0.8 to 1 meter high, and the shed is the same width and width. The degree of shading is 60% to 70%. After the insertion, the bed should be kept moist and not waterlogged. 15 to 20 days after insertion, the cuttings sprout, and new vines can be removed to gradually remove the shed. Prior to cutting, the base of the cuttings can be soaked for 6 to 8 hours with acetic acid from 5 to 100.000 parts of cesium, or 5 seconds at 1,000 to 3 parts per thousand of acetic acid, or Rooting powder treatment to improve the survival rate of summer plug. Cut off the cuttings is easy to lose water, should be cut with the plug, in the germination of new shoots, a small amount of multiple fertilizer, in order to ensure that the fall of the year the nursery quality seedlings.
