The mature season of plum blossoms is from the end of April to the beginning of May, and the picking time is only about 10 days, and it is not rich until July and August. Generally, plums do not grow naturally in early spring, so it is recommended not to buy and eat them. It is best to eat in season.

Plum blossom likes sunshine and warm and humid climate, which requires an annual average temperature of about 65438 06℃, shallow roots and poor drought and cold resistance. However, the low temperature below -8℃ at flowering stage or below -4℃ at young fruit stage will cause freezing damage, such as falling flowers and fruits and reducing production.

The requirements for soil are not strict, but the demand for potash fertilizer is large. Long life, it grows best on sandy loam with good drainage, fertility, leeward and abundant sunshine, and is suitable for hilly areas with an altitude below 500 meters and a slope below 25 degrees.

Breeding method of plum blossom:

The cutting time of Prunus mume is 1 day and 15 days per month. When cutting thick branches of annual Prunus mume, each branch should have more than two nodes with the length of 10- 15 cm. Cut a horse ear slope near the lower end of the axillary bud, and then row spacing 10 cm× 65438+. Cuttings with burial depth of 1/2-2/3.

Before cutting, soak ABT2 rooting powder developed by China Academy of Agricultural Sciences in a solution with a concentration of 100 ml/L for 5- 10 minutes to promote the division of cambium cells and accelerate rooting.

After the green plums are inserted, they should be watered, and shed for shade to prevent direct sunlight and avoid burns and excessive evaporation. Always keep the seedbed moist after cutting, but prevent water accumulation. In the later stage, we should manage it in the open field and pay attention to shading treatment in summer.
