Hammer elm tree shape is simple and beautiful, dashing posture, mottled bark, branches and leaves, wild resources are extremely rich, often see the stumps of wild styling peculiar down the mountain, high survival rate, adaptability, sprouting tiller force quickly, plasticity is very strong, resistance to coiling and pruning, branches and leaves can be tied piece, can be pruned into the natural form of the crown, suitable for the production of a variety of bonsai styling, the common straight stem type, slanting stem, horizontal stem type, cliff style, waterfront style. Commonly, there are straight stem type, slanting stem type, lying stem type, cliff type, waterfront type, attached to the stone type, planted together type and so on. In particular, shaping the rock hammer elm bonsai, in the intention can be intercepted in a corner of nature, allowing a certain degree of exaggeration, in order to render a certain part of the charm of the trees can be above the rocks, to the trees as the main, to the rocks as a second, without the restrictions of "zhangshan feet tree". China's bonsai school in the Lingnan school, Su school and Yang school, often to hammer elm as the main species.
Hammer elm bonsai production we have an article earlier, here will not repeat, we share today about some of the care of hammer elm bonsai notes.
A, deciduous or not
Hammered elm belongs to deciduous species, if the natural conditions, winter will appear physiological leaf drop. So bonsai artists will be in the winter leaf drop period, the hammer elm strong pruning and branching, better reflecting the hammer elm bone charm, so as to better shape the plastic. However, if the hammer elm bonsai indoor maintenance, the temperature is higher than 15 ℃, winter is not defoliation, if the temperature is 18 ℃ to 20 ℃ or more, there will be growth phenomenon.
Two, run pulp problem
About the hammer elm run pulp, is a lot of bonsai friends concerned about the problem, due to the hammer elm downhill pile root cross-section to see the water flow pulp, resulting in rotting, shrinking until the death of the elm pile more number. Generally after picking the pile to apply mud on the root to prevent dehydration slurry, however, many potters belong to the field to buy, after receiving the poor treatment, some will also take the soak rooting agent a kind of measures, so the root in the water under the soaking will also run slurry.
So it is recommended that the pot friends, after receiving the hammer elm downhill pile, do not use the rooting agent to soak, do not soak with water, you can rinse the roots and appropriate treatment, and then use a sharp knife to cut the cut off at the cut off smooth, applying healing agent, if there is no healing agent to use grass ash or erythromycin ointment, and then appropriate airing, such as the root healing agent after drying on the pots. You can mix disinfectant powder and rooting agent powder in the soil substrate in a low concentration. This treatment of the roots will not run pulp, pay attention to watering to be on the dry side, after watering the rooting water is generally not in the water, and so on after germination and then replenish the water.
Three, raise the embryo notes
One is a shallow planting of high circumference, because of the hammered elm downhill pile pile type simple, most of the roots gnarled and varied, easy to appear scars holes Shelly stem, etc., is very beautiful, the form is the main focus of the ornamental, and therefore more shallow planting of high circumference, and so the downhill pile to become a living! After, gradually remove the upper part of the virtual soil, so that hanging root dew claws, the demeanor is robust, very beautiful, do not need a second transplantation.
The second is the bag moisturizing, hammered elm downhill pile survival rate is high secret: root dry stem wet. Meaning that the roots should be kept in a dry state, conducive to rooting, stem cadres are kept in a moist environment, conducive to germination. Therefore, bagging or wrapping with plastic wrap is very effective.
Third is the slow acclimatization after germination. Hammer elm germination, if the rush to remove the moisturizing measures, there will be false live phenomenon, resulting in the death of the downhill pile. Therefore, to adapt slowly, can be plastic bags or plastic wrap holes to breathe, gradually adapt to the surrounding environment, until the second exhibition of leaves, indicating that the roots have been rooted, you can completely remove the moisturizing measures, which can greatly improve the survival rate.
Four, slow pruning
Hammer elm downhill stake the first year is not recommended pruning, so that the plant aerobic respiration and photosynthesis, so that the roots of the root vigorous, the second year to be appropriate pruning, do not rush to modeling.
Five, cut off the stem and store branches to pay attention to excessive
Hammer elm grows rapidly, Lingnan school modeling techniques cut off the stem and store branches is very suitable, however, must not be impatient, according to the overall shape of the moderate pruning, excessive must be natural, in the case of the upper branches did not basically form, do not rush to prune the graded branch, to avoid the upper branches of the weak, too abrupt, even if there is a deer, the upper branches of the weak, the upper branches of the weak, the upper branches of the thin, the upper branches of the thin, the upper branches of the thin, the upper branches of the thin. Excessive abruptness, even if there are antler branches, chicken claw branches and other forms, but also appears to be extremely uncoordinated.
Hammer elm bonsai production and maintenance, and years of work has a lot to do, even if it is a natural beautiful piles, but also need years of pruning and coiling, in order to form a pot of fine products, which requires patience and perseverance, as well as common sense. I see a lot of so-called experts, eager to achieve, graded branch a lot, but the lack of excessive in the first and second branch, the overall frivolity, the work of the year is very poor, but the so-called works of the people also put their own price tag of more than 100,000, which is just boasting, self-deception gimmick, I hope that the pot friends do not step after the dust.
