How to carry out cucumber plugging method
When the rootstock black seed pumpkin really broken heart, cotyledon hypertrophy, pith full, scion cucumber cotyledons can be grafted flat. Two days before grafting, the seedbeds were sprayed with chlorothalonil and anti-virus drugs to prevent diseases. When grafting, the temperature is 25°C and the air humidity is 90%. Grafting time is flexible according to the weather, and it can be grafted all day on cloudy days. It is best to take it in the morning on sunny days. On the day before grafting, the black seed pumpkin seedlings and cucumber scion used as rootstock were grafted into the footing water to facilitate the enhancement of plant activity and increase the survival rate after grafting. First, use a knife to make a bamboo stick about the same thickness as the scion hypocotyl. Cut two ends into 40 or so wedges. Then prepare a blade with a double-sided blade and then cut it in half lengthwise to cut the rootstock and the scion junction. Fingers and blades are sterilized with 75% alcohol cotton balls. When grafting, the true leaves and growing points of the rootstock are first cleaned with a blade to prevent the re-emergence of new true leaves in the leafhopper. Do not hurt the cotyledons. Then use your right hand to pinch the bamboo sticks, put the bamboo sticks face down, and pinch the root axis of the rootstock with your left thumb and forefinger so that the tips of the bamboo sticks come close to the inside of the base of one of the cotyledons of the rootstock and cut diagonally below the other one. The right cotyledon of the rootstock is obliquely inserted into the left cotyledon), and the insertion depth is generally 0.5-0.6 cm. Insert bamboo sticks to do three defenses: one anti-insertion broken rootstock cotyledons ring; two anti-insertion too deep (too deep will be inserted into the central cavity of the hypocotyl of the rootstock); three anti-cut through the rootstock of the epidermis. Then the head of the scion was cut off from 1.5 cm below the cotyledon, along the side without cotyledons, cut obliquely at a distance of 1 cm from the cotyledon to a slope of 0.5 cm in length and 40 in inclination. The opposite side also cuts the skin down vertically with a blade. After the scion has been cut, remove the bamboo stick inserted into the rootstock, place the scion face down, and slowly insert the rootstock. The depth must match the socket on the rootstock so that the scion cotyledon and the rootstock cotyledon cross each other. Do not use too much force when inserting scion. So as not to damage the structure of the scion, the depth of the scion insertion, in order to cut the mouth flush with the rootstock jack. The whole process from cutting scion to cutting scion must be stable, accurate and fast. Immediately after filling, pour enough water, place it in a small shed, cover the film, and pour enough water over the small shed to seal the film so that the humidity in the shed reaches 100%. Cover the shade with a straw curtain, a shade net, or a paper quilt.
