The latest cherry tree cutting technology tutorial

Cherry blossom trees are small deciduous trees of the genus Sakura of Rosaceae. Early cherry, evening cherry, weeping cherry, Yunnan cherry and other varieties are common in China. Late cherry is widely used in domestic planting and landscaping, and is widely used in landscaping. In production, it is often based on sowing, cutting and grafting breeding. Let's take a look at the cherry tree cutting techniques.

Cutting selection of cherry blossom trees

The cherry blossom tree should choose a young and strong mother tree, cut off one-year-old sturdy branches in the middle and upper periphery of its crown, retain the top tip, cut into cuttings 30cm to 40cm long, and cut into an oblique mouth in the lower part, and the cuttings cut on the same day should be finished on the same day to prevent cuttings from losing water, bruising incisions and tissue necrosis. Be sure to pay attention to the weak cuttings will reduce the survival rate, short cuttings will delay the seedling stage.

Making of cutting bed for cherry blossom trees

The cherry tree cutting bed chooses the terrain with good leeward drainage to the sun as a bed with a width of 1 meter and a height of 30 centimeters, and the bottom layer of the bed bed is covered with 15 cm thick sand loam with certain fertility. The upper layer is covered with 10 cm yellow core sand loam (prepared with 8 parts of yellow core loam and 2 parts of yellow sand) and sterilized.

Cherry blossom tree cutting time

The best time for cutting cherry trees is from mid-early June to early September, mainly because cherry blossoms are deciduous trees, annual big branch cuttings should be carried out before tree buds sprout, and cuttings begin to take root when the soil temperature reaches more than 16 ℃.

Cutting technique of Cherry Blossom Tree

When cutting cherry trees, use a stick thicker than cuttings and insert them vertically into the soil, with a depth of 5cm to 6cm and a spacing of about 10cm. Then insert the cuttings and press them with your hands. After inserting, spray through the water with a thin-eye spray can to make the cuttings closely combine with the soil.

Post-planting management of cherry blossom trees

1, moisturizing and heat preservation: usually the temperature in the first and middle of March is generally unstable, suddenly high and low, if the temperature drop is large, you can take emergency measures to cover the plastic film, such as the daily maximum temperature reaches 15 ℃ or more, spray once at noon, and spray 3 to 4 times a day with the steady increase of temperature in the later stage, so that the topsoil is not whitened. In order to improve the soil condition and make it form healing tissue as soon as possible, extra-root topdressing was carried out with 2% concentration of potassium dihydrogen phosphate 15-20 days after insertion. It took about a month or so to heal and take root.

2. Build a shading shed: after the cherry blossom trees are planted, the scaffolding should be set up to prepare for shading. The height of the scaffolding is slightly higher than that of people, so that it is easy to operate. It is conducive to ventilation and create a microclimate in the bed. When the highest temperature of the day is above 16 ℃, it is necessary to cover the curtain or use a shading net to shade, with a shading rate of 50% to 70%, and it is best to cover day and night.

3. Removing tillers and wiping buds: the sturdy cuttings of cherry blossoms are rich in nutrition, and the sun is sufficient and the temperature is too high. Buds and leaves begin to sprout in large numbers when they are not rooted. At this time, except for retaining the terminal bud, the rest will be erased to avoid excessive loss of nutrients.

4. Topdressing in time: in order to meet the growth requirements of cuttings, thin fertilizer should be applied in time one week after rooting, and then every 15 days. In this way, after three or four times of fertilization, the root group of the seedlings is developed, the growth is exuberant and can absorb the lower nutrients in advance, and the growth height can reach more than 1 meter in the same year, and the seedlings can be transplanted in the early spring of the next year to cultivate large seedlings.

5. Disease prevention and pest control: Cherry seedlings are vulnerable to diseases and pests, and their leaves are susceptible to leaf spot disease. Carbendazim with 800 times liquid can be sprayed once every semimonthly, and its terminal bud shoots are easy to produce tender shoot borer and aphids. Once newly hatched larvae are found, spraying should be done in time. To avoid damage to the seedlings.
