1, treated differently according to different ages.

Plum trees have different growth and flowering states at different ages and have different responses to environmental conditions and agricultural techniques, so different pruning methods should be adopted according to different development stages.

Small trees grow vigorously and there are many white branches. The main purpose should be to expand the crown, relieve the tree vigor and blossom early. They should be lightly cut, that is, other branches should not be cut except that the main branches are lengthened and cut short, so that they can bloom.

The growth of branches is reduced, the overgrowth of branches is obviously reduced, and a large number of flowers bloom. Therefore, we should solve the contradiction between growth and flowering by pruning, balance the tree potential, improve ventilation and light transmission, prevent the decay of the inner chamber and lower branches, maintain a good tree posture, moderately increase the pruning amount year by year, retract and update the backbone branches in time, and make the lower branches immortal.

2. Treat plum trees differently according to their growth.

Because of different site conditions and inconsistent management level, the growth of plants of the same variety and age often varies greatly. If the growth is vigorous, the pruning amount should be light. If the pruning is too heavy, it will inevitably lead to long branches, many branches, closed crowns and poor flowering. If the growth is weak, pruning should be increased.

3, according to the pruning reaction.

The growth position, posture and growth of branches of the same tree are different, so different pruning methods and appropriate pruning degrees should be adopted. In particular, the upright and vigorous branches, dorsal branches and twisted and drooping branches in the straight branches of plum blossom should be thinned out, the oblique branches should be retained, and the buds should be cut according to their development direction.

Extended data:

1, red plum is a kind of plum blossom, which can be used in gardens, green spaces, gardens and scenic spots, and can be planted singly, in clusters and in groups. It can also be planted naturally in front of houses, on slopes, between rocks and on roadsides. You can use evergreen trees or dark buildings as the background to set off the beauty of plum blossoms. In ancient times, it was emphasized that "plum blossoms around the house" and "going upstairs to see plum blossoms" were all for the best viewing effect. In addition, plum blossoms can be arranged into Meiling, Mei Feng, Meiyuan, Meixi and Meijing. Hongmei is also the object that China literati like to recite, and there are many paintings and poems. It is also the brand of cigarettes.

2, like warm climate, have certain cold tolerance, flowering period is very sensitive to climate change, Meixi air humidity is high, but avoid heavy rain during flowering period. Plum blossoms can also grow well in areas with annual rainfall 1000mm or a little more, which are not strict with soil and are relatively barren. It can also grow normally in weak alkaline soil. According to the experience in the south of the Yangtze River, when planted in gravelly clay and gravelly loam, plum blossoms flourish, flowers are strong and leafy. Active tree species, like sunshine and good ventilation. It is a long-lived tree species.

3. Hongmei is the spiritual symbol of the Chinese nation and China, with strong and universal appeal and impetus. Hongmei symbolizes the spirit of perseverance, perseverance, courage to struggle and self-improvement. The lofty quality and loyalty of marching forward against the snow, smelling the cold and smelling the fragrance, and being hard-core and cold-hearted have inspired generations of China people to explore bravely and create an excellent life and civilization. Some people think that Hongmei's character and integrity almost reflect the spirit of China people as "descendants of the dragon". The whole country, from celebrities to cloth clothes, has loved plum blossoms for thousands of years. "In the history of literature and art, the number of Mei poems and paintings is enough to make any kind of flowers fall behind." China people appreciate flowers, not only for their appearance, but also for their personality and spiritual strength.
