Sweet clover in October 165438+ Can you live by changing pots and pruning roots?

Sweet clover has strong germination ability. In most parts of Yunnan, it can be planted and transplanted every year in 65438+ 10 and 65438+ 10. The cultivation of veteran cadres also has a high survival rate. There will be clumps of buds on branches and roots. At this time, in order to ensure the survival rate of trees, it is best not to sparse buds. When new shoots grow for about 30 days to form branches, they will be selected according to the needs of modeling and pile damage.

Third, strong adaptability.

The native land of sweet clover is mostly karst landform, and there are many valleys in tropical and humid areas, but they are also distributed in mountainous areas with an altitude of about 2800. For example, Mount Mituo in Mengzi, Yunnan, is about 2300 meters above sea level, and it is also distributed. There are tributaries in the whole Nanpanjiang River Basin, Honghe River Basin, Wujiang River, Jinsha River and other valley areas. After artificial planting and landscaping application, it has been expanded to Guangdong and Guangxi, which can grow and reproduce well. At the beginning of 20 16, there was no large-scale death in most parts of Yunnan under the low temperature of -6 ~- 10℃. It can also adapt and grow completely in the subtropical and maritime climate of Guangxi and Guangdong.

Four, cutting and modeling points

Evergreen trees have many incomparable tree properties, such as hard as iron, burning in nature, rolling by falling rocks, and cutting down to form natural branches, which will not rot for a hundred years, forming a dry and glorious old tree state. Using this characteristic of trees, the lower part of the stump can be deeply cut according to the needs of trees modeling in the process of cultivation.

When cutting the branches of the stump, carefully observe the growth point of the tree itself. As long as the branches are cut in place, they can generally germinate on the spot. It is best to seal the incision with paraffin or plant healing agent to lay the foundation for viewing in the basin in the future.

The best cultivation soil for green piles is a mixture of 1 red loam and 1 humus. When planting, shallow seeds should be planted with high covering soil. When the new shoots grow to 60 ~ 80 cm, the high overburden soil should be removed in 1 ~ 2 times to prevent high floating roots. Except for those that need high floating to eradicate styling, they should be cut off.

In the modeling of sweet clover in Northeast China, I not only learned from the branch cutting and storage technology of Lingnan bonsai, but also summed up the method of directional branch storage with metal wires for the first branch. The fallen leaves of the second and third branches left growing points for shaping, which made the cultivation time of the second and third branches shorter, the branch angle better and the stump formed earlier. When the shoots grow to 30 ~ 50 cm, pull the twigs by hand to determine the direction, and at the same time, they can also be coiled and shaped with metal wires. After a vigorous growth period of about 40 ~ 50 days, the metal wire can be released to avoid being stuck. After the wire is removed, the growing point should be supported with bamboo sticks in time to make it straight and upward, so that the growth speed of branches will be accelerated and the growth will be balanced, and there will be no loss of branches.

In the growing period, branches can grow to 2-3 cm in diameter a year. For branches with larger diameter, they can be cut off and stored when they grow to 70% for 2-3 years, and the third and fourth branches can be finely cut, fertilized and watered after continuous storage, so as to accelerate the aging of branches and achieve satisfactory results.

5. Applicable technologies and management in modeling

In order to effectively prevent the occurrence of scale insects, soot diseases and other pests, we should strengthen lighting and ventilation, and timely thinning the branches and leaves that grow too densely.

Change the soil once every 2 ~ 3 years, and use slightly acidic soil with good drainage. When turning pots and changing soil, the old roots and diseased roots of the original plants can be cut off, and the high floating roots can be greatly trimmed and leveled, laying a foundation for the next root refining. In order to speed up the growth of plants, fertilization can be used, but water should be avoided, and it should be thoroughly aired and watered without water accumulation. Otherwise, the growth will be affected, and the plant will die. In order to accelerate the growth of directional branches, we can enhance the light in the direction of directional branches, increase the growth space, and put more branches and leaves to grow, which can get twice the result with half the effort.

The old state of branches can be cultivated by longitudinal cutting to xylem or manual kneading. In modeling, we should make a reasonable layout according to the changes of dots, lines, planes and blank spaces in China's traditional paintings and calligraphy. I have some experience about the corresponding angle between the trunk and branches of a tree: for example, the branches take acute angles and the front points are left blank. Drifting branches look at the trunk, bending forward and backward. When the branches are dotted, the scenery comes out. In the branch potential space, move the branch behind the big branch, and the branch should be supported upward. It is forbidden to have big branches and moving branches on both sides. The front branches should be short and thin, and the sides and back should be left blank. The larger floating branches should be matched with the trunk, and the points, lines and surfaces should be taken into account.

According to Bian Xiao, bonsai is the most expensive of all family greening flowers. Although the planting method of bonsai is simple, the shape of bonsai is difficult to take care of. The above are the maintenance and management techniques for the bonsai cultivation of Melilotus yunnanensis, and parents who are interested in bonsai can collect them.
