Grape grafting method, how to graft grapes

1, choose a good variety, disease-free, moderate thickness of robust branches as scion, used as scion branches on the fruit sequence and secondary tips in the 20-30 days before picking up removed.

2, grafting time is generally 10 days after the grape blossom, try to complete within 1 week, rather early than late, grafting two or three days before the vineyard watering. Grafting after 9 a.m. on a sunny day, the knife with a single-edged razor, grafting branch thickness and scion branch thickness to be roughly the same, are to be half-wooden, that is, the stem of the medulla oblongata. The scion should be used as it is picked. If you need to pick scion from a distance, you can use a wide-mouth thermos bottle storage and transportation, the bottle is filled with ice to cool and moisturize, to prevent water loss of scion.

3, grafting in the picking point under the first, between the two leaves cut into flat stubble, flat stubble in the middle of the mouth with a knife cut down 3 cm of incision, incision to the north-south direction, inserted into the scion buds towards the south is conducive to growth. Scion winter buds should be full back to the real, remove the winter buds next to the side of the buds, and then remove all the petioles under the winter buds. Each scion is 5 cm long, in the scion buds on the upper end to stay 1 cm, the lower end to stay 4 cm, scion buds on both sides of the lower 1 cm each downward cut 2.5 ~ 3 cm long mold-shaped slant, cut to be flat and smooth. Will cut the scion inserted into the cutting of the rootstock, aligned side of the formation layer, that is, aligned cortex, with a wide 1 ~ l.2 cm, 20 ~ 25 cm long thick plastic strip wrapped around the rootstock, from bottom up to tie up, and then use thin plastic strips to wrap all the scion tied up tightly, only to reveal the buds.

After watering a thorough watering, and then see the dry watering in a timely manner, after 7 to 10 days sprouting new shoots. The new tops of 20 to 25 centimeters high in time to insert a pole tied to prevent the wind from collapsing. Normally, we have to erase the secondary buds on the big tree. Each column between the selection of two plants to change (the best choice near the two sides of the column of 2 plants), each plant to 2 ~ 4 buds, grafting parts from the ground 1 ~ 1.2 meters, grafted plants normal results. Grafting 1 week to check the survival rate, poor survival rate of timely replacement. Check again 20 days after grafting, and select 1 to 2 strong plants to grow up, the rest removed. Later, pay attention to the timely tying and removal of the parapet.
