There are new tricks in fruit tree grafting
At the beginning of spring, it is the best time for grafting fruit trees. I. In the past, it was considered that fruit trees grafted better in early spring. Practice has shown that grafting time is best around 20 days before injury. If you choose and master this period, start with the local Liu Liu buds, as an indicator plant, indicating that all types of fruit trees can be grafted. However, for fruit cultivars, early germination can be achieved first. Second, in the past, it was generally believed that the grafting and scioning must first pass through sand traps, but in fact, the use of picking and picking would be better. In this way, the fruit trees will have a heavy texture and a large amount of water, and the sand will easily lose water. Third, the traditional single bud grafting method was changed to two buds hedge method. The specific methods are as follows: 1. Leave 1-1.5 cm at the top of the bud, and tie it with a plastic film. Its purpose is to prevent the infiltration of water in the pith and the evaporation of water. 2. Cut a short face from the bud's front face and cut it 0.5 to 1 centimeters long. It is a 45-degree incline, and gently scrapes off the outer skin with the upper end and the long noodles to see that the green is not visible and cannot expose wood. 3. Cut the rootstock 2-3 cm away from the ground. Select the smooth side, cut 1/3 to 1/4, can't cut a knife perpendicular to the pith, its length is equal to or better than the long face of the scion. Use a knife or hand to gently open the cortex and the wood, remove the xylem and keep the cortex intact. 4, the scion quickly cut long face inward, short cut face outward, the skin is the skin, the bone is the bone, insert the rootstock incision about 2 cm deep, so that formation layer alignment, with plastic film packing tight, only exposed on the bud. Fourth, the conventional piles used in the past were replaced by low piles. The specific method is: Before grafting, the soil around the rootstock is slightly opened. After the grafting is completed, the soil is covered to the buds of the scions. However, the bud eyes cannot be covered with soil. After survival, open the soil. The purpose of doing so is to keep warm moisture and sunscreen, which is conducive to wound healing and improve the survival rate. China Agricultural Network Editor
