When will the cherry blossoms blossom in 2020?

The opening time of cherry blossoms is affected by air temperature, Rain Water and other factors. It is estimated that most of the cherry blossoms in China will bloom in mid-late March in 2010. A cherry blossom lasts about 7 days from blooming to withering, and the whole cherry tree blossoms and falls while blooming. The cherry blossom blossoms in March.

2. Cultivation techniques of cherry blossoms

1. Planting

The ground should be leveled before planting. A hole 0.8 meters wide by 0.6 meters deep can be dug. The pit is first filled with 10 centimeters of organic fertilizer, and the seedlings are put into the pit so that the roots of the seedlings stretch around. After filling the soil with cherry blossoms, lift the seedlings up to make the roots spread out deeply. The planting depth is about 5 cm from the upper layer of the seedling root. water it after planting, fully irrigate it, and set it up with a stick to prevent it from being blown down by strong winds.

When planting, 15 kg-25 kg of rotten compost was applied to each pit, and 1 kg-2 kg of ammonium sulfate was applied to each plant in July. After flowering and before sprouting in early spring, it is necessary to cut off dead branches, diseased and weak branches, and avoid pruning coarse branches as far as possible, so as to keep the crown complete.

2. Watering

After planting, the seedlings are vulnerable to drought. In addition to full irrigation during planting, they should be irrigated once in the next 8-10 days to keep the soil moist without stagnant water. Loosen the soil in time after irrigation, it is best to cover the surface thinly with grass to reduce water evaporation. Within 2-3 years after planting, in order to prevent the trunk from drying, it can be wrapped with straw. However, after 2 to 3 years, the seedlings grow new roots and gradually increase their adaptability to the environment, so it is no longer necessary to cover grass.

3. Fertilization

Cherry blossoms are fertilized twice a year, and acid fertilizer is better. One was winter fertilizer, which applied organic fertilizers such as bean cake, chicken manure and mature fertilizer in winter or early spring, and the other applied quick-acting fertilizers such as ammonium sulfate, ferrous sulfate and calcium superphosphate after falling flowers. General big cherry tree fertilization, you can take the method of hole application, that is, in the crown: the edge of the projection line, dig a circular ditch about 10 cm deep, apply fertilizer. This method is not only simple and beneficial to root absorption, but also increases the diameter and depth of ring trench with the growth of trees. The root distribution of cherry blossoms is shallow, which requires good drainage and ventilation, so people, animals and vehicles should not stand firm in the soil around the tree, especially in the range of root distribution. Pedestrian trampling will weaken the tree, shorten its life, and even cause rotten roots to die.

4. Pruning

Pruning is mainly to cut off withered branches, overgrown branches, overlapping branches and disease and insect branches. In addition, when many branches grow on the trunk of large cherry blossoms, a number of strong branches should be retained, and the rest should be cut off from the base to facilitate ventilation and light. The pruned branches should disinfect the wound with medicine in time to prevent the invasion of bacteria after rain, resulting in decay. Cherry blossoms after a long period of sun exposure, the bark is easy to aging damage, resulting in decay, it should be removed in time and disinfection treatment. After that, the rotten part was bandaged with rotten leaf soil and carbon powder to promote its normal physiological function.

5. Disease and pest control

Cherry blossoms should mainly prevent gum disease and root nodule disease, as well as aphids, red spiders, shell insects and other insect pests. Gummy disease is caused by moths drilling into tree trunks to lay eggs, which can be dug out with sharp knives, improve the soil and strengthen the management of water and fertilizer. Root nodule disease can cause the roots of diseased trees to fail to grow normally. No matter how much fertilizer is applied, the tree is still not strong. It is necessary to remove the tumor in time, carry out soil disinfection, and use rotten leaf soil, charcoal powder and microorganisms to improve the soil.

Due to the short blooming period of cherry blossoms, friends who want to enjoy cherry blossoms in 2020 can start to pay attention to the blooming of cherry blossoms in early March.
