Euonymus japonicus is evergreen, adaptable, extremely resistant to pruning, is a good hedgerow material, easy to shape and anti-pollution, is one of the indispensable evergreen tree species in northern cities. Its rapid propagation technology is particularly important, rapid propagation is mainly based on cuttings, and tender cuttings are carried out. The survival rate is over 96%. 1. Nursery facilities and slotting bricks, cement build up about 20 centimeters high, 1 meter wide bed, 18 centimeters thick matrix, the bottom of the matrix is ​​5 to 8 centimeters thick sand, the upper layer of fine sand. A water pipe is erected at a height of 50 cm from the bed, and a centrifugal or four-body sprinkler head is installed on the pipe every 1.5 meters for spraying. Before cutting, the seedbed was disinfected with a 0.3% solution of potassium permanganate. 2. Materials collection and treatment The upper part of the middle crown, no pests and diseases, and robustly grown annual semi-lignified or fully lignified shoots were harvested from the superior young plants of Euonymus japonicus. Sprinkle immediately after the shoots are removed to prevent dehydration and wilting. Cuttings are best collected in combination with pruning. With cuttings, the cut branches are cut to a length of 10-15 cm. Each cutting has not less than 2 or 3 buds. The base leaves are removed and the upper part is retained. The upper cuttings of the cuttings on the leaves were cut 0.5 to 1 cm above the cuttings, and the lower cuttings were cut obliquely 0.5 cm below the section or under the petioles. The cuts were smooth, no injury, no cracks, and no damage to the skin. After the cuttings are cut, they are bundled according to coarse classification and processed in time or directly. The base of the cuttings can be quickly spun with ABT rooting powder solution for 5 to 10 seconds to promote healing. 3. Cutting and slotting management Euonymus japonicus can be cut all year round. In the spring, summer and autumn seasons, small sheds need to be erected for the cuttings, and shady sheds should be built above the small sheds in summer. Cuttage in early March can be transplanted in the same year. In late September to late October, cuttings were transplanted early after soil thawing in the following spring. The cuttings can be used with the shears, and can be inserted in the acetic acid solution before insertion, and can also be directly inserted. The cutting depth is 2/3 of the cutting, and the cutting density is 600-700/m2. After cutting, 800-1000 times of carbendazim solution was sprayed through the matrix to disinfect. Immediately after the seedbeds are filled, they must be sprayed. Eyesight should be sprayed twice a day in the morning and in the afternoon, and once every half an hour at noon. Each time 5 to 10 minutes. Increase the number of sprays during the hot summer months to reduce the temperature. One week after insertion, callus can be produced. About 20 days later, 90% of new roots are produced. After hair rooting, pay attention to reducing the number of sprays and time, to prevent rot caused by root; and to spray 0.2% ~ 0.3% of urea or compound fertilizers to conduct extra-root fertilizer, to promote the healthy growth of cutting seedlings. 4. After 15 to 20 days of cutting, the seedlings begin to root, until the cuttings form a complete and plump root, and then the seedlings are started. The number of water sprays is reduced day by day and the number of ventilations is increased. 10 to 15 days after the gradual removal of the plastic film, and then after 10 to 15 days gradually withdraw the shading net, the full photosynthesis seedlings. Seedlings continue to stay in bed for more than 20 days, you can transplant seedling colonization. When transplanting, it is necessary to keep the root system intact and watering with the plant to ensure the survival of transplanting. This method can be used for cutting propagation of boxwood seedlings three times a year, which greatly shortens the seedling cycle and improves seedling quality. In addition, we must unplug the bed when the weeds grow. When the soil is over-consolidated, a small spade can be used to gently loosen the soil between the rows, but it is not easy to get too deep to prevent the base of the cuttings from being injured and affecting the root growth.
