Pruning method of boxwood bonsai
1, material
Seedlings propagated by sowing or cutting can be transplanted into flowerpots for processing after several years of cultivation. You can also choose the old wooden stakes in Shan Ye, dig them out and repair them.
Long roots and dense branches are first cultivated in the open field. 2 years, then add soil to the pot.
2. On the washbasin
① Choice of pot: Poplar is always oily green, so it is advisable to use purple sand pottery pot, and the color of the pot is purple or yellow. The shape of the basin depends on the modeling form. The cliff type should use a deep thousand-barrel basin, and the inclined dry type or curved dry type should use an oval or rectangular basin.
② Soil: The soil of bonsai is cultivated on the basis of mature pastoral soil or humus mixed with appropriate amount of ridge bran ash. The soil is fertile and loose, and the filling soil with good ventilation and water permeability is preferred; The pots on the old pile should be covered with soil.
③ Planting: Boxwood is cold-resistant, which can be carried out before germination in the second season. When planting, the root system should be trimmed too long and too dense, and the root nest should not be bent in the basin. The newly planted boxwood should be placed in a semi-shady place.
3. Modeling 1. Poplar has strong germination ability. Before modeling, the trunk can be truncated to allow new technologies to sprout around or under the part. Then, according to the requirements of artistic modeling, it is best to climb the branches in winter and tie them with brown silk thread. It can also be roughly tied and finely cut, made into clouds or steamed bread, or processed.
Become a natural tree. The trunk is naturally made into inclined stem type or prone type. If the boxwood stump landscape is decorated with beautiful stones, it will become "boxwood". Boxwood is very resistant to pruning and has strong germination. In order to maintain a beautiful tree shape, it must be processed and shaped frequently.
Maintenance method of boxwood bonsai
Boxwood bonsai with sufficient sunshine and moisture should be placed in a place where the sun can shine in the morning, cool in the afternoon, well ventilated and the rain depends on nature. If you watch it indoors, you'd better let it go to the sun and rain for ten days and a half. Potted Euonymus japonicus should always be moist, because root absorption, leaf photosynthesis and the whole growth process need a lot of water. Of course, the demand also changes with the seasonal climate. Buxus macrophylla grows in a small pot in the garden, which comes from the edge of rivers and streams. The biggest change in the environment is that the humidity of the environment is small, which depends on our maintenance to supplement it in time and properly. Therefore, we should pay attention to the climate, technology and quality when watering. When the temperature is above 20℃ and there is water shortage in the basin, watering is divided into three steps: step one, washing the immobile soil to meet the water demand in the basin; Step 2, soak and water the branches and leaves from multiple angles; Step three, spray. In summer or when the temperature is above 20℃ and there is no water shortage in the basin, water should be done according to the second and third steps; The temperature is below 20℃ and above 10℃, and there is no water shortage in the basin. In the sunshine in the winter morning, water once a day according to the third step. After the "white dew" in autumn, when the dew is dry, spray water according to the third step. Don't water it in the morning and evening on frosty days; Don't water before the March 9th cold wave, to prevent frozen soil and frozen branches and leaves, and keep the basin well ventilated.
The thin fertilizer and diligent application of Euonymus japonicus should adhere to the principle that fertilizer is mainly used as fertilizer, natural fertilizer and human and animal manure. Carefully apply chicken and duck manure and high-efficiency fertilizer, remember not to apply undecomposed fertilizer and excessive fertilization, and apply thin fertilizer frequently. Before the season changes, apply some seasonal fertilizers, such as accelerating germination in early spring, strengthening foliar fertilizer in summer, resisting temperature in summer and keeping warm in winter; Apply some topdressing after each pruning, more topdressing in rainy season and summer when crossing the basin during the day, and appropriate fertilization when the growth is not good.
Boxwood with scissors as the main shape is hard and brittle, and the branches are thin and easy to be hurt, so we should pay attention to the selection of piles first, and then we must carry out shape modification according to the situation. You can also tie the sola with a rope properly, and it takes several times to branch it in place, that is, you can't be demanding or eager to achieve success, otherwise it will be counterproductive. Avoid twisting branches with rusty iron wires to prevent skin damage and dead branches.
The trunk of Euonymus japonicus bonsai grows slowly and vigorously, but the twigs grow faster, and the density of leaves will inevitably lengthen, making it soft and loose. Only by "pinching" can the ornamental value be guaranteed. That is, before the branches are lignified, one pair, at most two pairs of young leaves are left, and the rest are picked or cut off. Under proper water and fertilizer conditions, two buds will be issued in ten days and a half months. In this way, its branches appear short and thick, and its leaves can be multiplied by the product of 2, which constantly improves the ornamental value. Then it is necessary to sprout in time. Boxwood began to sprout before summer and autumn, and bloomed in spring. The nutrients needed by flowers and fruits account for 70%-80% of the whole tree, which will inevitably affect its normal growth and beauty. We mainly look at leaves. Therefore, it is necessary to sprout from the beginning.
The roots of Euonymus japonicus are mostly fleshy and fine roots, and its water and nutrient absorption is mainly the absorption function of root tip, followed by the length of root arm. The root is too long to stretch out in the pot. Bending and folding are very harmful. Moreover, in order to absorb nutrients, the root tip will naturally extend forward and contact new soil. The roots grow long, and it won't be long before the root tips hit the wall. Although the root tip will turn, it takes time and energy to affect the growth. In particular, the wall and bottom of the basin will soon be covered with roots, forming a soilless "root plate" and changing the basin body. This forms a vicious circle. It is not advisable to exchange soil for pots. Cut off the long roots exposed on the soil surface. The best season for changing pots is to germinate after rooting in early spring. Second, after changing pots in midsummer season, they will be prosperous again after being placed in the shade for seven or eight days.
Curly moth larvae like to suck the leaf juice of Euonymus japonicus. After the moth is born, it can roll up the surrounding leaves. It hides in the middle and sucks the juice from the leaves. In two or three days, it will suck up the juice of the curly leaves, leaving a white vein network. At this time, it will move and hurt again. If not killed in time, it will destroy all the leaves in five or six days. Not only ruined beauty, but also killed people who didn't look good. As long as the common "inhalation death" or "contact death" can be eliminated, it is important to find it in time and put it out in time. It is worth noting that in summer, especially when the temperature is above 30℃, the eggs of the leaf roller moth can hatch into harmful insects in just three or four days, and the replacement is the fastest. So when the temperature is high, it is best to kill once a week.
How to fertilize boxwood bonsai
Boxwood avoids strong light, so it is only suitable for astigmatism when planting, not for strong light irradiation. Boxwood that has just come down the mountain or has been transported for a long time and just turned over should be kept in the shade for a period of time before being transferred to normal maintenance. It can be sprayed with extremely dilute diluent of nitrogen fertilizer and urea for 2000 times all year round, and contact with phosphate fertilizer and potash fertilizer is prohibited. You can also add a small amount of nitrogen fertilizer when watering, so that the leaves are very beautiful, dark green and shiny.
Why can't potash fertilizer be applied?
Potassium mainly exists in plants in ionic state and does not participate in the composition of important organic matter. Compared with nitrogen and phosphorus, potassium plays an important role in reproductive growth centered on flowering and fruiting. Therefore, for downhill piles with long buds as the center, the effect is not obvious, but there are side effects. The main reason is that, on the one hand, with the increase of potassium ion, the concentration of stomatal guard cell fluid increases, which makes the stomata wide open and the water in the body is easy to lose. On the other hand, the accumulation of potassium ions needs corresponding energy supply, which aggravates the consumption of limited "inventory" of downhill piles and is not conducive to improving the survival rate. Excessive potassium fertilizer can easily cause leaves to turn yellow and fall off, and even cause plants to die due to breathing difficulties. The demand for phosphate fertilizer is very small, so there is no need for special topdressing.
Foliage fertilizer can sometimes play a role that soil fertilization can't. For downhill reactors, the required mineral nutrients can be obtained quickly and timely, photosynthesis can be promoted in time, inventory shortage can be replenished in time, and survival rate can be improved. Topdressing outside roots is a quick-acting nitrogen fertilizer, and nitrogen is a "life element" in the process of cell protoplasm formation and metabolism.
