Cultivation of Old pile of Ulmus pumila

Grasp the water spray level in the billet stage

Although it is easy to transplant the old pile of hammer elm, it is easy to raise it. But do not spray water on the branches during the period of raising billet, so that the upper soil has a certain degree of humidity. If the billet is cultivated in the ground and pot, the stump and branch are sprayed frequently in the stage of promoting root growth, the humidity of the branch and root is too high, and the moisture in the cortex of the tree is saturated. Tree sap will seep out and lose, seriously affecting survival, which is a link that people do not pay attention to. In practice, there is often such a thing, some are not easy to dig back ideal wild old piles from the wild, twist heart branches and stems lack of water in the process of planting and potted blanks will affect survival, constantly spraying water to old piles, sometimes several times a day, the result is counterproductive. Love is eager, but I haven't seen the new buds for a long time, until I die, I still don't know why. The reason is that the old piles that often take root at the end are sprayed with water, and the wounds where the sap has never healed seep out, and when the sap runs out, it becomes a dead pile, which is often caused by spraying water to the pile billet. The elm sprouts easily. As the temperature rises, the old pile slowly sends out new buds, but the good times do not last long, and soon the new leaf buds begin to wither. What is the reason for this? At this time, when the old school is pulled out of the soil, it will be found that the old pile does not take root, and some of the roots are black. this situation is called false living, and these buds are maintained by the nutrition of the old pile itself. once the nutrition is exhausted, it becomes a dead pile. To distinguish the true and false life depends on the color of the new bud. The bud of the lie is neither lustrous nor spiritual. when it grows to a certain point, it no longer grows and begins to wither; the normal new bud is shiny, and the longer it grows, the more energetic it is, which proves that the old pile has taken root and is expected to survive. Therefore, do not rush to let the hot sun exposure, pay attention to shade. Gradually withstand the sun. Adapt to the environment. The old pile planted in the ground should not be in a hurry to die in that year, so that its roots are developed and then put on the basin.

Turn off digging, fertilizing and pest control.

After putting on the pot, the hammer-happy old pile is generally fertilized with water, and the pot is changed for 2-3 years. Watering master do not dry do not water, scratch must be watered far. High fertilizer season every day 'times. Winter is too dry and less watering, watering directly scratch the root, do not spray the leaves [regiment: the old school after shaping above should not spray water on the leaf surface in the maintenance process, as usual spraying foliar water will cause the branches N "to grow, make the leaves bigger, not only affect the beauty of the tree shape. It is also very easy to cause aphids and caterpillars to gnaw off leaves and twigs. If the Df is placed for too long, when there is a lot of dust, the bonsai can be moved into the attached middle school and washed when it rains. When you find aphids or caterpillars, use diluted dimethoate and doinling to spray the leaves to kill the pests. Although Lang Happy old pile bonsai is more extensive than ordinary tree species in pile landscape management, it is good to raise it on the 9th day, but we should also pay attention to a few points.
