Drupes subglobular, furrowed, l 1 to 3 cm in diameter, densely pubescent, sour in taste, green, from April to June when the fruit ripened mostly yellow or yellow-green, and some varieties are red and green.

Growth characteristics Plum blossom like warm, humid climate, in sufficient light, good ventilation conditions can be better growth, soil requirements are not strict, barren resistance, cold resistance, afraid of water. It is suitable to grow on moist soil with loose, fertile topsoil, good drainage and slightly sticky subsoil. Love warmth and plenty of light. In addition to the apricot varieties can withstand minus 25 degrees of low temperature, generally resistant to minus 1 degrees of low temperature. High temperature resistance, can grow at 40 degrees. It grows and develops best in the area with an average annual temperature of 16 ~ 23 degrees. It is very sensitive to temperature, flowering in early spring when the average temperature reaches minus 5 to 7 degrees, if the low temperature, the flowering period is delayed, if the low temperature when flowering, the flowering period can be. The growth period should be placed in a sunny, well-ventilated place, if in the shade environment, insufficient light, growth thin, rare flowering. In winter, do not enter the room too early, in late November is appropriate. In winter, it should be placed indoors, and the temperature should be kept at about 5 degrees. 3. Breeding and cultivation method is commonly used to reproduce, and rootstocks are mostly plum, peach, apricot, mountain apricot and mountain peach. Plum blossom cultivation in the open field, should be on the sunny slope or half sunny slope, plant distance of 3 to 5 meters. Usually fertilize 3 times during the growth period, that is, fertilize from autumn to early winter, such as pancake fertilizer compost, manure, etc. Apply quick-acting fertilizer before budding; After the shoots stop growing (late June to early July), appropriate water control and fertilization are applied to promote flower bud differentiation. Plum blossom is suitable for bonsai cultivation. Potted plants after years of cultivation. The basin soil should be soft, loose and fertile, and should be shaped and trimmed before and after planting. (1) Planting. In the south can be planted in the ground, in the Yellow River basin cold varieties can also be planted in the ground, but in the cold areas in the north should be potting room over winter. It can be planted after falling leaves until spring bud. In order to improve the survival rate, it is necessary to avoid damaging the root system and transplanting with soil mass. Planting should be chosen in the lee of the place. The culture soil with 3 parts of rotting leaf soil, 3 parts of garden soil, 2 parts of river sand and 2 parts of decomposed manure was used for pot cultivation. Water through once after planting. Put in shade for maintenance, and move to the sun after the growth is restored to normal trim o l 26 (2). The pruning time can be carried out within 20 days after flowering. Take the natural tree shape as the main, cut off cross branches, upright branches, dry branches, too dense branches, etc., and cut the side branches short to promote flowers and leaves. The potted plum blossom should be re-cut after the pot to lay the foundation for the production of bonsai. Usually to plum pile for the scene, grafting various gestures of plum blossom. Keep a certain temperature, the Spring Festival can see plum blossom. If you want to "May Day" bloom, you need to keep the temperature O ~ 5 degrees and a humid environment, move out of the room in early April, placed in a sunny, well-ventilated place for maintenance, you can see flowers before and after "May Day". (3) Flowering control. Potted plum blossom is generally for family viewing. After the winter leaves are placed indoors, the temperature is maintained at O ~ 5 degrees, gradually warm to 5 ~ 10 degrees after the New Year's day, and fully accept the light every day, often spray water to the branches, the water temperature should be close to room temperature. After the winter is over, the plum blossoms come to life in spring. When the potted plum blossom soil is watered in a humid environment, and applied inorganic fertilizer and farm fertilizer at random, immediately moved to the outside where it is not warm, so that it can not bloom in the spring. 20 days before the Spring Festival began to gradually increase the temperature to 15 ~ 25 degrees, and need sufficient light, good air. Control watering, basin soil does not do not pour, humidity is too big easy to lead to rapid growth, flower buds put together, affecting the viewing. Spray the branches with water once or twice a day to prevent drying. When the bud is not put, according to the need, depending on the actual development of the bud, flowering too fast, can be moved to the low temperature to control slow opening; Flowering is too slow to catch up with time, and can be appropriately increased temperature. Degree to encourage it to open early. The drought resistance of plum blossom is poor, it is necessary to spray water around the plant often, if the humidity is insufficient, the leaves are easy to turn yellow and wrinkle, directly affecting the flowering. After winter, Dendrobium should apply less fertilizer, and phosphate fertilizer, potassium fertilizer and appropriate amount of nitrogen fertilizer should be applied to promote flowering. Potted plum blossom is divided into large plum pile and small bonsai according to size. o Plum bonsai is a wild plum pile grafted cultivar, after many years of cultivation. . Small potted plum is cultivated from small seedlings. First of all to choose easy to form flower buds, flowering. Dense, while taking into account floral, colorful varieties. Press 30 to 50 centimeters first. ; 10 drift 127_| Stength Plant the seedlings on. Then grafting, root shaping, pruning and cultivation. After 2 to 3 years of cultivation, and then in winter or early spring out of the pot. Basin soil should be used with humic soil, and some garden soil and fine sand can be added to ensure the permeability of the soil. Then trim the roots and branches according to the shape of the plum pile, so that the pot can be placed at the best viewing Angle. 4. There are many kinds of plum diseases, the most common are powdery mildew, leaf shrinkage, anthrax and so on. (1) mildew. This disease often occurs in an environment with high humidity, high temperature and poor ventilation. In early spring March, when the plum blossom bud, the buds and new leaves are susceptible to germs, the affected parts will appear very thin white powder layer, and then the white powder layer appears pinhead size black or yellow particles, and the leaves turn yellow and die later. (2) Shrinkable leaf disease. Can spray tobuzin or carbendazim control, can also spray 1% Bordeaux liquid, spray once every other week, 3 to 4 times can cure o (3) anthrax. At the early stage of the disease, 70% tobuzine 1000 times solution or 600 times zinc spray can be used for prevention and treatment.
