Purple-leaf is a deciduous tree of the genus Rosaceae. It is native to China and widely cultivated in North China and its areas south of the country. It is an important tree species for gardening. Purple-leaf plums are 6 to 7 meters high. The leaves are purple-red, obovate, and serrated. The flowers bloom from mid-April to mid-May. The flowers are light red or pink, solitary, and the fruit is spherical. Purpleleaf hi light, drought-tolerant, more cold-resistant, strong nature, strict requirements on the soil. Planted on leeward sunny, well-drained sandy loam grows best. If it is planted in the shade, plant growth will decline, and leaves will be dark. Planting in low-lying areas will cause water accumulation and cause rot. When fertilizing, two or three bowls of fermented ring fertilizer can be applied to the pit during planting. Afterwards, some organic fertilizers can be applied at the beginning of spring each year to make the plants grow vigorously and bloom in a variety of colors. When watering, it can be used before the spring starts. Before and after the autumn frost, pour each frozen water and frozen water. Normally, if the weather is not too dry, water is not needed. Note that the purple leaf is not tolerant to flooding, and the drainage work should be done in time to prevent the rain. Plant damage caused by rot roots; pruning of purple peony, usually done after defoliation in winter, the main cut off the plant's dense branches, drooping branches, internal litchi and pests and branches, but also with the shape, will The long lateral branches were cut off and the crowns of the plants were plump; the purple-leaf pests, moths, and moths were necessary for the pests and diseases of purple-leaf plumes, and 40% of omethoate EC was used to spray and kill them. Because the leaves of the seedlings of purple-leaf plum are mostly changed to green, the bud-joining method is generally adopted for the propagation of purple-leaf plumes. The bud-joining method is not only simple and easy to operate, but also requires only three or four years of cultivation to become a plant and blossom. The grafted rootstocks are generally selected from the 2-year-old nectarines, which are preferably used for rootstock cultivation. Before grafting, they should be cut off in advance. Only the 5-7cm stumps on the surface should be reserved. In mid-late June, the scion should be selected in advance. The buds are set on the shoots. The shoots must be full and full of shoots, no dry tips and pests. Using a sterilized bud cutting knife, cut into the xylem at a 30-degree angle, 2 cm below the bud position, until it is 1 cm above the bud position, and then cut a knife over the bud position (1 cm). Gently remove, and then in the rootstock 3 cm away from the place, with a knife in the bark cut a "T"-shaped incision, so that buds and rootstock tightly combined, and then tied with a plastic strip can be. After grafting, the buds did not show signs of wilting in about 7 days, indicating that they had survived and the plastic tape could be removed in about 25 days.
