Cultivation method of red plum
First, use soil
Red plum is not strict with soil, and loose, permeable and humus-rich loam is better. Frozen and brittle pond soil mixed with 30 ~ 40% rice bran ash is often used as culture soil for potted plants.
Second, water.
Keep the basin soil moist at ordinary times. Don't do it or water it to prevent water from accumulating in the basin. May to June. That is, the flower bud differentiation and formation period. Want to do it? Withholding water? Let the soil dry until the old leaves are slightly rolled up, and then water them when the new buds shrink. Repeat this several times, destroy the growth point of new branches, stop elongation, increase flower bud development, and then resume normal watering.
Third, cultivation, propagation and pruning.
1, planting; Plum blossom should be held in11~ 65438+February, or after flowering. Generally, the seeds should be planted obliquely, which is convenient for modeling. Before planting, you can trim it once. Base fertilizer can be placed on the basin bottom.
2. Choice of pot: Red plum should use purple sand pottery pot or glazed pottery pot, generally not too shallow. Inclined dry type and curved dry type are used in deep manger pots or round pots, square pots and hexagonal pots. Cliff-style thousand pots. Attitude control technology
3. Processing: ① The new branches bound with plum blossoms are easy to grow naturally. In order to ensure the beautiful appearance of the tree, it needs to be tied with ropes in time to make it bend and shape according to people's wishes. The shape of plum blossom strives to be true and natural, such as bending upwards, generally not more than three bends. When pruning, it is best to combine pruning with binding, so as to make plum blossom form an ancient and vigorous graceful posture as soon as possible. (2) The shape of red plums is mostly "roughly tied and finely cut". When the trunk reaches 65,438+0 cm in diameter, it can climb, and the lateral branches can also be roughly tied, with brown silk or metal wire, and the rest are trimmed. For the newly born flower branches every year, according to the needs of modeling, brown silk can also be used for climbing and binding. The processing of trunk and big branches should be in winter, and the processing of new branches should be in autumn and September. Be careful not to hurt the bud. 4. Tree shape: For the shape of red plum, the ancients had many evaluation criteria. For example, "Mei wins with rhyme, with high lattice, oblique and thin, with old branches strange, more expensive". "Plums are four expensive: expensive and rare, not expensive and complicated; Your old age is not expensive; Your thinness is not expensive and fat; Is it expensive to drive? " "Mei takes pleasure as beauty, but straight is without posture; Take beauty as beauty, and the law has no scenery; Sparse is beautiful, and secret is stateless. " And the bonsai of red plum in China is modeled according to the above principles. Generally speaking, the trunk should be inclined and the branches and leaves should be sparse, but not just sparse. It should be sparse and dense, and the density should be appropriate and picturesque.
5. Pruning of plum blossom bonsai is very important. Plum blossoms form buds when new branches are born that year, so they should be pruned in time after flowering every year. After flowering every year, the old branches should be cut off, leaving only 3 ~ 4 buds, and pay attention to making the buds grow outward so that they can bloom in early spring of the following year. Pruning can also be combined with shaping. Cross branches, parallel branches, overlapping branches, long branches and weak branches that affect the beauty of the tree should be cut off. Combined with turning pots, we should cut off dead roots and shorten the roots of elders. And replace 1/2 old soil. Cultivate fertile soil to promote growth. Fourth, fertilization.
Pay attention to the season and growth period when fertilizing. When turning the pot, put bone meal and decomposed bean cake crumbs at the bottom of the pot as base fertilizer, apply cake fertilizer water 1 ~ 2 times as topdressing before flower bud formation in the middle and late May, and then apply 1 ~ 2 times in the early August. After autumn, continue to fertilize for 2 ~ 3 times, and put it in the greenhouse in winter. Spring Festival can blossom early.
Five, the environment, light cold in winter.
Hongmei likes light, warm and humid climate and is cold-resistant. The soil is fertile and loose sandy loam, rich in humus, sticky, with poor drainage and easy to rot and die. Therefore, plums should be planted in sunny, dry and well-ventilated places. It should be placed in a sunny and ventilated place.
Growth habit of red plum
Likes warm climate, has certain cold tolerance, and the flowering period is very sensitive to climate change. Mei likes high air humidity, but avoids heavy rain during flowering. 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.
Garden application of red plum
In gardens, green spaces, gardens and scenic spots, red plums can be planted alone, in clusters, in groups, etc. It can also be planted naturally in front of houses, on slopes, between rocks and on roadsides. If evergreen trees or dark buildings are used as the background, the beauty of plum blossoms can be set off.
Hongmei: Choose tall and plump plants to plant in important places or places with concentrated sight, such as near the entrance, courtyard or lawn, and make a scene independently, and pay attention to the strong contrast with the surrounding landscape in order to obtain? A little red in the evergreen tree? Effect. It can play the role of the central viewpoint of the landscape or guide the line of sight.
Cluster planting:
Embedding plants such as red plum in the garden green space not only enriches the landscape color, but also enlivens the garden atmosphere. If you plant green trees, it can play a icing on the cake. The arrangement of species in different flowering stages can prolong the viewing period. This layered configuration and color matching is an important way of garden art. Different leaf colors, patterns and colors, and different plant combinations at different heights enrich colors and levels.
Group planting or slice planting:
Taking red plum as the main tree species, it is planted in groups to form a scenic forest with unique leaf color and posture. Its beautification effect is far better than pure green scenic forest.
