Purple dwarf cherry tree is very popular in landscaping because of its short plant shape, compact crown, purple leaves and high ornamental value. The unit is located in the Yanqing Horticultural Center in Dingzhou City, Hebei Province, which is a plain yellow land. In 2002, it introduced the purple leafy dwarf cherry tree, which is now all survived and grows well. The cultivation points are now described below.

Planting options

Purple Dwarfing Cherry has a strict requirement for soil and can grow normally in light clay, loam and plain sand, and grows best in sandy loam. Purple cherry dwarf cherry tree is a hybrid of purple cherry and dwarf cherry, so it inherits some of the advantages of purple plum. It can tolerate light saline-alkali soil. The purple leafy dwarf cherry tree grows in a place where the light is insufficient, and its leaf color is green, so it should be planted in ample sunshine; the purple leafy dwarf cherry tree is a humid environment, but it is not resistant to stagnant water and should be planted in a place of high dryness. Avoid planting in low-lying areas and no adverse reactions are planted in the lawn. However, it should be noted that sprinkler irrigation should be used for lawn irrigation.

Water and fertilizer management

Purple dwarf cherry drought, each year in early spring and late autumn can be poured enough to return to Qingshui water and frozen water, usually if not particularly dry, basically can rely on days of growth. The spring and autumn breeze is a great drought. After the newly planted seedlings are exhibited, the leaves are sprayed once a day and in the afternoon to supplement the water, reduce the pressure on the roots, and increase the survival rate of the seedlings. In the summer rainy days, the stagnant water in the tree pits should also be promptly removed to prevent the water temperature from rising after the sunrise and scald the root system. Purple-leaved dwarf sakura, fertilizer, new planting seedlings in addition to the application of base fertilizer, in the growing period should also be appropriate fertilizer. In the early spring and early summer, topdressing nitrogen fertilizer, phosphorus fertilizer, and potassium fertilizer are applied once. At the end of autumn, circulatory fertilizer or sesame sauce slag is applied once more. For newly planted nursery stocks and seedlings with poor fertility, foliar fertilization can be conducted with a concentration of 0.5%. The selection should be conducted in the early morning or late afternoon, and should not be carried out after noon light and rain before rain. 3 times is appropriate, the interval time is 10 days to 15 days.

Winter Management

The purple dwarf cherry tree is hardy and the adult seedlings can take the measures of whitening the trunk. For the newly planted seedlings, the method of rooting the soil and arranging the grass in the trunk may be adopted, and the young seedlings may be covered with a film. After the new planting seedlings are wrapped and dried in the first year, they can be painted over the winter for the second year.

Pest Control

In the process of cultivation, purple dwarf cherry trees are harmed by moths, aphids, spider mites, leaf fleas, and scale insects. Every year in winter, when painting white, both main trunk and big branch are painted white, and eggs and insects should be scraped clean. In the early spring, broad-spectrum fungicides such as chlorothalonil and carbendazim should be sprayed in time. Diseases should be treated in time if they occur, and moths, aphids, leaf fleas, and scale insects can be killed by deltamethrin, and spider mites can be controlled by diclofenac.

Pruning

Purple dwarf cherry tree is resistant to pruning, and its pruning should be treated differently depending on the plant type. The common plant types of purple dwarf cherry are "broom type" and "natural happy type".

"Broom-type" is generally used as a piece of planting or as a hedge: plants used as a hedge, trim height is generally about 0.6 meters -1.2 meters, can be carried out in the late spring and early autumn every year, so that the hedgerow surface is flat, highlighting the side of the hedgerow Shoots should also be cut off; planting ornamental seedlings on the pruning is relatively extensive, cut off the pests and branches, cross branches, dead branches, internal litchi, proper removal of dense branches, in order to facilitate ventilation.

"Naturally happy" seedlings are generally used for planting and planting. Purple leafy dwarf cherry is a shrub that is dominated by foliage, so pruning should preserve as many shoots as possible, remove some back branches, cross branches, and competing branches, and keep 3 to 4 internal litchi. When it is about 40 centimeters, it is picked up to promote the lignification of the shoots and more lateral branches.

Overwintering management and pest control: Purple dwarf cherry cold, nursery management size seedlings do not have to engage in cold measures, but in the summer and late autumn, pay attention to aphids, white planthopper insect pests, can use insecticide phosphorus 1:800 times spray, the effect was significant With. Dingzhou Xinyuan nursery stock base after many years of management experience, purple dwarf cherry tree, blue peach, purple leaf plum, spring dry slightly caused by the white planthopper, as long as the strengthening of management, generally will not produce frost damage.
