Several Effective Measures to Prevent Loss of Mountain Nails
Mountain nails, small wax trees of this family tree, have entered the ranks of bonsai trees and have gradually become popular with people. However, because the bark of the mountain nails is relatively thin, in the case of poor management and insufficient water supply, the stump loses water or local water loss, and the old branches easily die, causing the bonsai to lose its branches. How can I avoid loosing mountain bonsai? Several precautionary measures can be taken during the cultivation process: After excavating the flowers, the heads of pots on the pile heads are used to excavate the tops of the nails on the mountain, and the timing is better after the nails are cut. At this time, at the turn of spring and summer, the climate is mild and moist, and the plants grow hair roots, shoots, and leaves quickly. As long as watering is in time, the survival rate can reach 100%, and the reserved branches will not dry up. The best time for Guangdong to excavate the nails on the top of the mountain basin is from Qingming to Xixia. Shrinking shears reserve a new growing branch Nails on the basin during the cultivation process, due to the need for modeling, often the thick branches or trunk shrinkage. At this time, new growth branches should be bred under the kerfs so that the shrunken twigs and stems can continue to maintain photosynthesis so as not to lose water and dry branches. In order to prevent the emergence of “yin and yang branchesâ€, that is, the side with new branches continued to grow, and the side with no new branches withered, forming the same branch with half of the dead half of the phenomenon, should be combined with the shape, both sides of the section below the pre Leave new branches. If the bonsai needs to cultivate semi-gloomy "Yin and Yang branches" to enhance the sense of vicissitudes, it is another matter. The section is coated with latex paint and seal the mountain nails into a cluster, branches are particularly large. The new branches are thicker than the old branches. Excavating the pile heads and basins will inevitably lead to sawing off most of the branches. The cut-offs are large and numerous. Apply latex paint to seal water. The shrinkage of the upper pot after cultivation, the diameter of more than 2 cm, should also be coated with latex paint to prevent loss of branches. There are many germinating buds after pruning the mountain fingernail. It is necessary to scrape buds early and set the branches early. Also, do not change branches frequently. Small cuts and cuts can be made. Timely watering makes piles not dehydrated. The day-to-day management of mountain bonsai bonsai is the most important part of watering. In summer and autumn, or dry wind, it is watered every day, and it is sometimes poured every morning and evening. To maintain its vitality. The roots of the mountain nails are very developed and flourishing, and consume more water. The water supply is not timely. The twig's head immediately hangs down. The piles are short of water and the old branches are easily dehydrated and die. Business trips, leisure travel, a few days, we must not forget to arrange for others to water, or regret too late! It is not appropriate to pick out light leaves for the exhibition of bonsai in Lingnan. The customary practice is to “strip off the leaves for brocade†and remove all the leaves so that they germinate new shoots and show new leaves during the exhibition. This method is not suitable for all tree species. Mountain nail bonsai is not suitable. Although watering continued during the exhibition, but there was no mountain nail pile head of the leaves, the water absorption capacity of the roots was reduced, and the bark was poor in water delivery, which caused the old branches and “Yin and Yang branches†to partially lose water and die. The degree of pruning during the exhibition of mountain nails can be seen in the season and timing of the exhibition. In the vigorous stage of sprouting, the cutting can be carried out with less leaves, and in the hot and dry season, it can be cut lightly and leave more leaves.
