Summer grape seedlings

Grape seedlings in summer can be harvested in the fall of the year. This is an effective way to shorten nursery. The method has the advantages of short occupation time, high survival rate, reduced winter storage process and investment, good seedling quality, strong growth, and good economic benefits. The specific method of operation is as follows.

Cutting time should be carried out from June to August. When the new vine was grown to 5 to 10 knots, it was the best time for cutting.

The preparation of seedbeds for slotting requires good lighting, convenient irrigation and drainage, and loose and fertile soil. After the seedlings are ploughed and leveled, a slot of 1 to 1.2 meters wide is made. It is estimated that 3 to 4 rows can be inserted, and the spacing between the rows can be 6 to 8 centimeters. After the nursery is in place, it is ready for use. At the same time, scaffolds and branches are provided for shading.

Cutting methods Cuttings should be selected lignified, spring buds are yellowish brown, cut into small pieces of 20 to 25 cm long (with 3 to 5 sections), the cutting tip leaves a leaf, other leaves together with the petiole cut out, the lower end Cut from the bud into the horse's ear and cut it in time to insert the seedbed, pour enough water and set up the shed. The arbours are 0.8 to 1 meter high, the sheds are the same width and width, and the shade 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. Before cuttings, 500 to 700 PPM of indole acetic acid can also be used to soak the base of cuttings for 6 to 8 hours to improve the survival rate of summer insertion.
