Maintenance methods of Japanese evening cherry

Japanese evening cherry is not heat-resistant. In summer, if the temperature exceeds 35 ℃, we need to open both ends of the shed for ventilation. We can spray water outside the plastic shed, which can not only cool down but also avoid excessive water content of vermiculite. Avoid sun exposure in summer!

Maintenance knowledge of Japanese late Sakura

Cultivation techniques of Japanese late Sakura

Japanese late cherry blossoms are excellent varieties of cherry blossoms because of their large, double, bright color, fragrant smell and long flowering period. The grafting propagation is slow, the operation is tedious, and the hardwood cuttings are difficult to take root. With vermiculite as the substrate, the annual branches with tender shoots were cut at full flowering stage, and the survival rate was very high. Expanded vermiculite was used as substrate to keep pH 6.2. the temperature of vermiculite seedling bed at night was 2 ℃ to 3 ℃ higher than that of soil bed, while the temperature at noon was 1 ℃ to 2 ℃ lower than that of soil bed, which indicated that vermiculite seedling bed had small temperature difference between day and night, large accumulated temperature and good heat preservation effect, which was beneficial to root growth. In production, granular vermiculite is the best, which has good permeability and is conducive to rooting. On the other hand, the powdered vermiculite is sticky and has poor permeability. When raising seedlings, vermiculite should not be mixed with soil, otherwise the roots will rot easily. The cutting time can be carried out from April to July, and the survival rate of cutting in the blooming stage of cherry blossoms is the highest, and the plant is in the peak period of physiological activity, so it is easy to root. The seedlings were cut on April 28 and did not slow down after transplanting on June 28. 0.5 cm new buds germinated 5 days later, and the trees bloomed after 4 years of culture. Selection and treatment of cuttings (1) selection of cuttings: 15 cm-long branches were cut from a sturdy mother tree, with annual shoots at the top and annual branches at the bottom. The leaves on the new shoots can produce nutrients, the annual branches have been lignified, and the cuttings are easy to survive. Most of the 3-to 6-year-old branch cuttings rot and die. The survival rate of cuttings is related to age. The older the branch is, the weaker its physiological function is, and the more difficult it is to survive. (2) treatment of cuttings: the leaves inserted into vermiculite should be removed before insertion, and the upper leaves should be retained. The cuttings were quickly dipped in 1000ppm naphthylacetic acid. Namely: insert the cuttings at the base of 2 to 3 cm into the 1000ppm naphthalene acetic acid solution, then immediately take out the cuttings and dip them along with the cuttings. The cutting method uses bricks to build a seedbed with a height of 20 cm and a width of 1 m (depending on the number of cuttings). The bottom of the seedbed is covered with 2-3 cm of river sand, and then filled with vermiculite 15 cm thick. Install a centrifugal sprinkler every 1 meter, or use a sprayer rod connected to the tap pipe to spray. A shady shed was built in early May, and branches were used as fences around to protect the wind. For heat preservation and moisture preservation, plastic sheds can also be set up on the seedbed. The cuttings are inserted vertically in vermiculite with a spacing of 2 cm and a spacing of 4 cm, and are filled with water after insertion. The cutting depth is 6 to 8 cm, because it is observed that the temperature at the depth of 5 cm is 2 ℃ to 4 ℃ higher than that at the depth of 10 cm, and most of the healing tissue and adventitious roots grow at 6 to 8 cm. After-insertion management is often sprayed, and keeping the leaf surface moist is the key to survival. There are more times of spraying at noon when the temperature is high, and the interval is shorter. Do not spray when there is dew at night and in the morning, the relative humidity of the air is kept above 90%, and the humidity of vermiculite is maintained at 58% to 60%. This target must be achieved before taking root, especially before the formation of healing tissue. In early May, a shade should be set up to protect against the scorching sun. When the temperature in the plastic shed exceeds 35 ℃, open both ends of the shed for ventilation and seal it when the temperature drops to 27 ℃. If the weather is too hot, water can be sprayed outside the plastic shed, which can not only cool down but also avoid excessive water content of vermiculite. Transplanting time and methods transplanting in time when the root system of cuttings grows to 6 to 8 centimeters. After transplanting too late, the root system of the cuttings will turn brown and rot, and the leaves will gradually turn yellow. This is because vermiculite can only keep warm, moisturize, aerate and promote root, but there are no nutrients for cuttings to continue to grow. In addition, the cuttings with few roots or only callus without rooting should be kept in the seedbed until the roots grow well before transplanting. Creating an environment suitable for the continuous growth of cutting seedlings is the key to ensure the survival of transplanting. A fertile plot without stagnant water should be selected to make a north-south border with a length of 8 meters and a width of 0.3 meters, mixed with sandy loam soil 30 cm deep, and then covered with 2 cm thick sandy loam soil. Flatten the border surface, plant a row in each border, plant 30 cm apart. Put the root system of the cuttings together with the surrounding vermiculite into the planting hole and cover the hole with sand. Don't press hard so as not to break the tender roots. Then fill the border with water and build a 1.2-meter-high shade on it. Spray 2 to 3 times a day, keep the leaves moist, the ground is often watered, dry and wet. The seedlings transplanted in this way are not slow, the survival rate is high, and the growth is normal. The results of the study on the effect of IBA treatment on the middle and basal segments of the annual branches of Japanese late cherry trees showed that IBA could significantly improve the rooting rate of cuttings and the quality of cuttings (reflected by the strong seedling rate), and the rooting rate and strong seedling rate of the basal segment were better than those of the middle segment. For Japanese late cherry green wood cuttings and IBA treatment, it is appropriate to select the base of the current year's branches of one-year-old trees as cuttings. Planting and cultivation 1, seed cultivation-- seed less 2, branch cutting rooting-- it is difficult for Prunus to take root by cutting, which may be related to the accumulation of inert substances in dormant branches. 3.

Disease Control of Japanese late Sakura

During the prevention and treatment of root nodule disease, nodules appeared in the root of the plant, with different shapes and sizes, brown to dark brown in color, and cracked epidermis often appeared in the rough epidermis, which occurred on or near the root neck of the ground or where the rootstock joined with the scion. After being damaged, the plants often show poor growth and short plants. Prevention and treatment: dig up the damaged plant, rinse the soil, soak the root in 1% copper sulfate solution for 5 minutes, rinse, and then plant; remove the tumor, and apply 0.1% mercury solution to the wound, and then plant. In the early stage of anthracnose, there were round disease spots on the young leaves, and perforations could be formed after the disease spots healed. After June, the leaves hardened, the disease spots on the leaf surface were rough, and the disease spots were brown irregular spots. When the disease is serious, it can cause a large number of fallen leaves and cause withered buds. Prevention and control methods: 1000 times of mancozeb wettable particles or 50% carbendazim wettable particles and 1000 times of carbendazim wettable particles were sprayed alternately for 3 times and 4 times with an interval of 7 days. Leaf spray on plants is prohibited during the disease period. When brown spot perforation disease occurs, there are grayish brown round spots at the beginning of the leaf, and with the development of the disease, it gradually forms round spots about 3 cm in diameter, with clear boundaries, purplish brown on the outside, white-brown in the middle, and wheel markings. The disease spot died and fell off to form an irregular perforation. Prevention and treatment methods: after the onset of the disease, 50% plus 1000 times of Ruinong liquid can be sprayed for prevention and treatment, once every 10 days, continuously spraying 3 times for 4 times, which can effectively control the disease.

Variety classification of Japanese late cherry

In Japan, horticultural classification refers to wild species as "mountain cherry" and artificial breeding and natural variation as "inner cherry". The common varieties of cherry blossoms in Chinese gardens are: Yunnan early Sakura (P.majestica) is native to Yunnan. The flowering period is from late February to early March. Flowers before leaves, deep red flowers, about 25 petals, flower diameter of about 2.5 cm, flowers are half-blooming, drooping, sepals red. The young leaves are brown with tea. Prunus x yedoensis is an important cultivated variety of Japanese cherry blossoms, which is a hybrid of Oshima Sakura and Edo Sakura, which inherits the characteristics of large flowers and first flowers and then leaves, respectively. Florescence in mid-March, single pink, 4-or 5-flowered racemes, hairy on sepals and pedicels. The tree is tall and can reach 10 to 15 meters. Oshima Sakura (P.lannesiana var.speciosa) is a representative of wild cherry blossoms, which can be up to 15 meters tall. The florescence is in the middle of March, and the flowers and leaves bloom together. Flowers white, single, corymbose open. Calyx tube long bell-shaped, sepals lanceolate, margin serrate, flowers glabrous as a whole. Many varieties of cherry blossoms are derived from Oshima Sakura. P.lannesiana Sekiyama is a variety of Japanese evening cherry, which is widely cultivated in China. At the end of March or early April, the flowers and leaves bloom together. The flowers are thick red, about 6 cm in diameter, about 30 petals and 2 gynoecium, so they cannot bear fruit, and the pedicels are thick and long. The young leaves are brown with tea. The branchlets are numerous and curved upward. Peony Sakura (flower red, pink) rain shelter (flower white)
