In books, periodicals and web pages, it is suggested to close the incision with white latex, but the effect after my test is almost zero. People who hold this view apply the method of sealing the cut of miscellaneous wood with white latex to pine trees. As we all know, pine trees are different from miscellaneous trees, and gum turpentine will flow out for several days. The white latex originally coated on the incision will flow out with the turpentine overflow, so it is impossible to seal the pine incision with white latex.
It is not practical to seal with erythromycin ointment. Erythromycin ointment is a kind of ointment. When gum turpentine flows out of the incision, soft ointment can't stop turpentine from overflowing, saying it can prevent wound infection. In fact, most plasters are lost with turpentine spillage, and only a few are stuck on the wound, which has little effect.
Seal with mud. After my own experiment, the effect is good. When I cut the branches of Pinus armandii on the mountain, I rubbed the wounds with the plain soil on the mountain. The next day, I observed that there was no rosin flowing out of the wound. The original gum turpentine and solid soil adhered to each other and solidified together, effectively preventing the outflow of turpentine.
Glass glue seal. As long as the glass glue is coated on the incision, rosin rarely flows out. Because of the fast solidification speed of glass glue, rosin will not overflow, but will be forced to crystallize at the incision, effectively preventing rosin from overflowing. In addition, glass glue is waterproof and can be used even in rainy days. One thing to note is that the sap of thick branches flows quickly and has great pressure. When cutting these pine branches, resin may overflow, which will crack the glass glue and lead to resin outflow. Therefore, some thick incisions should be painted thicker, or painted the day after the existing resin overflows.
Second, the pruning time
Many pot friends suggest pruning pine trees in cold and slight cold seasons when changing pots. The reason is that pine trees are dormant in winter and the sap flows slowly. At this time, less rosin overflowed from pruning will not affect the normal growth of pine trees. This question is debatable. Pine trees are different from other tree species. With the continuous growth of trees, the outer branches and leaves are more and more lush, while the inner branches and leaves close to the tree will get less and less sunshine and rain because of the cover of the outer branches, so they begin to turn yellow and fall off. A large number of deciduous branches will become bare branches (referring to branches with long branches but only needles at the end), thus making the whole tree loose in structure and greatly reducing its ornamental value. At this time, in order to improve the ornamental value, the branches must be cut short to force buds. Different from other miscellaneous trees, pine trees must have some needles to force buds when pruning (otherwise the whole branch will die), which determines that only some branches with needles at the end can be pruned to force buds at a time, while some long bare branches are often difficult to approach buds, or it takes a long time to prune them many times to get satisfactory results. Therefore, in normal times, especially in the vigorous growth period of pine trees, the branches of pine trees should be properly pruned (as long as they are sealed with glass glue, it will never affect the growth of trees) to control the advantages of branches, promote the growth balance of the whole tree and ensure the normal growth of dense branches and leaves.
Third, the problem of leaf cutting.
Cutting more or less leaves seems simple, but it is actually related to the survival of pine trees, so we should not be careless. Some potted friends found that the whole tree or local branches died shortly after pruning, which was closely related to excessive leaf pruning. In this regard, the author also paid a lot of tuition fees. Generally speaking, it is safe to cut off half of the leaves of a normal growing pine tree at a time, and it has little effect on its growth after cutting. For the robust pine planted in the ground, even if it is cut again (about 4/5 of all needles are cut off), it is safe and can force out the ideal bud position. For some weak pine trees, it is necessary to strengthen the management of fertilizer and water, and then cut them when their vitality is strong. If the weak pine trees are cut down again, the trees will die. So before cutting, you should pay attention to the vitality of pine trees, and then decide how many branches and leaves to cut. Don't make a move.
Potting technology of fruit tree seedlings | How to trim and make fruit tree bonsai and matters needing attention in maintenance
Potted fruit trees and bonsai are one of the common plant ornaments in our modern life, and this kind of ornament needs careful care without ordinary ornaments, so it needs attention in the process of production and maintenance. Potted fruit trees have appeared in people's lives for a long time, but in the past, people regarded them as a kind of fruit tree propagation, hoping to pick fruit trees in the future. But today, this potted plant exists in people's homes as a bonsai, mainly as an ornamental to decorate the home. So how to make and maintain this potted bonsai of fruit trees? Let's take a look at the production and maintenance of potted fruit trees and bonsai.
Matters needing attention in making potted fruit trees and bonsai
1. In the production of potted bonsai for fruit trees, the words "to put the pot on" and "to pour the pot" are often heard. In fact, the so-called pot loading is the process of transplanting fruit trees from the ground to the flowerpot, while the pot dumping is the process of transplanting fruit trees from a small pot to a large flowerpot. Under normal circumstances, the production of fruit tree potted plants or bonsai should be based on the specific situation at that time, and the fruit trees in the appropriate period should be selected for production, and the healthy and robust fruit trees should be selected for potted plants and bonsai production. When planting flower pots, it is necessary to avoid cutting off the main roots, so the survival rate of fruit trees is very low. Moreover, in the production process, people usually prepare nutrient soil for fruit trees, which needs to be made according to tree species, pots and conservation environment.
2. Generally speaking, dwarfing techniques and grafting methods are used in fruit tree potted plants and bonsai production. Fruit trees are generally very tall. If you want to make beautiful potted bonsai, it is very important to dwarf it by using dwarfing rootstocks of various tree species, and grafting is more common. The potted bonsai made by this method has high survival rate and is more exquisite. At the same time, no matter what kind of potted plants and bonsai you make, you need to trim and shape them. This requires specific analysis of specific problems, usually just a little pruning according to the natural shape of fruit trees to make potted bonsai look more natural and beautiful.
Matters needing attention in maintenance of potted fruit trees and bonsai
1, in the process of maintenance, we should also follow a principle, that is, concrete analysis of specific problems. Because the demand for maintenance of each fruit tree is actually a little different, but in general, the problems that everyone needs to pay attention to are the fertilizer and water problems of fruit trees, the light and temperature problems, and the pruning problems of plants. In terms of fertilizer and water management, it should be noted that in potted plants and bonsai, the water demand of plants is generally large, because the water in potted plants and bonsai is easy to lose, so it is generally necessary to water them frequently, but not for fruit trees with strong drought tolerance. Fertilization depends on the specifications of the fruit tree during its growth period. For example, fruit trees need a lot of nutrients during the fruit-bearing period, so they should be fertilized frequently, but generally speaking, thin fertilizers should be applied frequently.
2. In the process of fruit tree potted and bonsai maintenance, light and temperature also need everyone's attention, but this needs to be adapted to local conditions. Usually, people like to place fruit tree potted plants and bonsai near the indoor window sill, because the air here is ventilated and the light is sufficient, which is quite good, but different maintenance methods should be adopted for different fruit trees. As for the pruning of fruit trees, it can be done according to personal hobbies or the natural growth trend of plants, and it is good to prune potted fruit trees and bonsai according to the basic principles of smooth growth and elegant appearance.
How to Trim Jasmine with Tiger Head How to Trim Jasmine with Tiger Head
As we all know, jasmine is a flower plant that grows vigorously and often needs pruning, and often needs pruning again. Many people treat tiger jasmine just like ordinary jasmine, but it is actually wrong. I want to remind you here that the jasmine with tiger head can't be pruned again!
Compared with common jasmine, jasmine grows very slowly. If you trim it too much, it may not be restored for a long time. Ordinary Jasminum nudiflorum may recover in a month or two, while Jasminum nudiflorum may not recover to its best state in three months or even half a year, which may lead to the failure to sprout new branches or even the whole branch dying. Therefore, when pruning, we must grasp its degree.
You can't prune the winter jasmine when the temperature is low. Pay attention to whether there is sunshine when pruning, and it is best to prune when there is sunshine. When pruning, the top branches should be kept for a long time to avoid shrinking branches, and fungicides should be sprayed in time after pruning.
Even in normal seasons, the cut of jasmine gourd head should be treated, sealed or disinfected. (Note: Potassium permanganate or highly alcoholic liquor can be used for disinfection. Pruning is not recommended before and after Qingming, which is vulnerable to germs. )
Tips When pruning potted jasmine, you should consider the overall size of the plant and the proportion of flowerpots. If you accidentally trim it too heavily, you must try to bask in the sun and not lack light. Only in this way can jasmine wake up as soon as possible and sprout again.
Common problems in flower cultivation are dealt with in the following ways.
1 It is normal for a new plant that has just changed pots to lose one or two leaves, and the newly bought plant or plant moves to another room with a slightly changed environment. Pay attention to using a slightly larger pot when changing pots. When you buy plants to take home, you should pay attention to protecting them, and gradually move them from the shade to the bright place to minimize the stimulation to them.
2. The leaves at the bottom dry and fall off.
There are three reasons: lack of light, high temperature or lack of water.
3 plants grow slowly or not.
Among the common family plants, almost all plants will grow slowly or even stop growing in winter, so we can't rush into it. In summer, the slow growth of plants may be caused by lack of water, too much watering, root rot and too little light. If these reasons are not available and the temperature is suitable, it may be that the roots are full of pots, which limits the growth of plants.
4 Rot of stems and leaves
Poor growth environment, caused by disease. The reason is that there is too much water in winter or there is water on leaves at night.
The leaves of five mosaic varieties turn green.
There are usually two reasons: too little sunlight and too much nitrogen fertilizer. Move the plant to a place with strong light, remove the branches of green leaves and reduce the amount of nitrogen fertilizer applied.
Moss grows on the edge of the pottery basin.
There must be something wrong with watering, which is usually caused by excessive watering or blocked drainage holes at the bottom of the basin, too wet soil or accumulated water.
7 leaves small color light, slender stems.
If it happens in winter or early spring, it is because the temperature is too high, the light is too weak and the substrate is too wet. If this phenomenon occurs during the growing period, it may be caused by lack of fertilizer or insufficient light.
8 no flowering
If a plant grows to a certain size, it will not bloom when it blooms. There are several reasons: The most likely reason is that the light is too weak, and the number of hours of light per day is wrong (photoperiod). It may be that there is too much nitrogen fertilizer, the air is dry, pests and diseases or improper pot changing (some plants will bloom when their roots are full, so there is no need to change pots).
9. Browning of leaf tips and edges.
If only the tip of the blade is brown, it may be caused by hot air, or it may be a scratch. Leaning against the wall or window, the tip of the blade may also turn brown. There are many reasons for yellowing or browning of leaf edges: too much watering, lack of water, insufficient light, too strong light, too high or too low temperature, too much fertilization, too low air humidity or too strong ventilation.
White alkali appeared in 10 soil basin.
Pour hard water or apply too much fertilizer.
