What season do plum blossoms bloom and what season do plum blossoms bloom?

The flowering time of plum blossoms in different regions is from December to January in southwest China, February to March in central China, and March to April in North China. The first flowering to the full flowering is 4 7 days, and the final flowering is 15 to 20 days.

However, the cold plum does not bloom in winter, but in very early spring, which can be regarded as the end of winter and the beginning of spring, when there is often snowfall and the temperature has begun to rise. Other varieties of plum blossoms bloom in the first month.

Plum blossom season: The southern region blooms early, generally in January. The northern region has a cold climate and generally blooms in March-April.

Plum blossoms like snow, and the blooming time of plum blossoms is generally between January and April, when the temperature is low, and the flowering time is different in different regions.

Conservation of plum blossom opening:

Controlling the temperature, humidity, light and fertilization and watering during the flowering period can prolong the flowering period, otherwise the flowering period will become shorter and the desired effect will not be achieved.

Keeping the temperature of the flowering period above 5 can prolong the flowering period and avoid the phenomenon of interrupting the flowering period caused by too low temperature, indoor cultivation and greenhouse cultivation can increase the temperature, early flowering and prolong the flowering period.

It is best to keep the soil moisture in a humid environment, but avoid standing water, and watering should be done during periods of higher temperature to avoid lower temperatures.

In winter, there will be no burn problems, and the maximum amount of light and light intensity will be maintained, which is conducive to flowering and brilliant flowers.

Fertilization during flowering can maintain flowering for a long time, and phosphorus and potassium fertilizers are the main fertilizers, which can effectively supplement the nutrient consumption of plants during flowering.

The flowering period is winter and spring, and the fruiting period is from May to June (the fruiting period is extended to July and August in North China).

Extended information: The plastic pruning of plum blossoms is a key technology in plum tree management. It is an important part of the plum tree to maintain a good tree shape and tree momentum, and to promote the normal flowering of plum blossoms. Therefore, an appropriate time period should be selected for reasonable and scientific pruning.

1) Shaping and pruning of young trees.

The juvenile period of plum blossoms is short, and generally grafted seedlings can grow more than 1 meter in that year. The main trunk is mainly based on the needs of garden modeling, such as single-stem street greening seedlings, weeping varieties seedlings, etc., should be cut off about 70 cm from the ground to the upper branches; For example, natural heart-shaped landscape seedlings and bonsai seedlings should be cut off at 50 cm or less from the ground. In the summer of that year, the dense buds and tillers were erased, and 6 8 buds were left in each direction in the shaping belt 20 25 cm below the cut for main branch culture.

In winter, light pruning in order to quickly expand the canopy to form the basic skeleton, pruning 1 4 1 3 of the main branch length (varies depending on the species) according to the desired lateral branch direction, leaving 30 60 cm. In the summer of the second year, the erect and overly dense new shoots were cut off, and the growth was moderate and the orientation and position were selected as side branches for cultivation. In the later stage, summer and winter pruning is mainly carried out according to the needs of the tree shape, and the dead branches, diseased branches, dense branches and long branches in the canopy are pruned in time.

2) Prune before and after flowers.

After 3 to 4 years of cultivation, plum blossoms grow vigorously, the canopy expands, and they gradually enter and exit the full flowering period. The main purpose of pruning this period is to prolong the flowering period of plum trees (Yan Xiaolan, 2002). Before flowering, it is necessary to prune large branches such as cross branches, overlapping branches, dead branches and diseased branches, and then thinning the thin branches that are too dense and too weak, the main purpose of pruning is to make the tree shape more beautiful and retain sufficient nutrients to prolong the flowering period.

The pruning time after flowering is short, generally 90% to 95% of the flowers are opened, and the remaining residual flowers are suitable until the leaves are spread. If pruning is too late, the nutrient consumption of the tree will be large, which will affect the growth of plum blossoms in the current year, and then affect the overall growth potential of plum blossoms. In addition to the pruning of dead branches and diseased and insect branches, retraction pruning is mainly carried out during this period.

As the plum tree grows older, the crown expands too much, which causes the inner chamber and lower branches to lack light, resulting in a gradual weakening of growth and sparse flowering. Therefore, it is necessary to carry out different degrees of retraction pruning of the main branches, side branches and flowering branches according to the growth situation year by year. Then, appropriate thinning is carried out according to the germination ability of different varieties.
