How to plant a bonsai? Material selection?

To improve the survival rate of new stumps, the key is to make them take root early and grow fast.

According to the physiological function of plants, whenever the body is injured, it will stimulate its cells to accelerate division to make up for its losses and achieve physiological balance, which is the role of diecui regeneration. In order to make the roots of new stumps form quickly, it is necessary to trim the ends of the main roots neatly so that new roots can grow around the new parts. In addition, you can also use a sharp knife to cut a few knives in different directions around the thicker roots. Generally, young roots will grow around the wound. Even if it cannot take root, it will not affect the growth and beauty of the stump. Roots grow faster in weak light than in strong light, and faster in dark environment. According to this truth, the stump head can be placed in the dark or covered with black mud to promote its rooting. Plant growth regulators can also be used to promote the rooting of stumps. Pay attention to the following questions when pressing the roots. First of all, master water supply. Don't let the roots get too much water. Too much irrigation, new roots have not yet grown, but buds have grown a lot. Once the water is insufficient or the air is dry, plants are easy to die. Secondly, choose the appropriate temperature for culture. When the soil temperature is higher than the air temperature, plants germinate behind the roots, or the roots grow fast and slowly, because absorption is greater than evaporation, and trees are easy to survive. So we must try to avoid planting new stumps when the temperature is high. Generally, it is most suitable when the temperature is 20 to 25 degrees Celsius and the relative humidity is 80 to 90%. Finally, don't pick buds at will. Don't pick new buds casually, even if they are useless, keep them for the time being. Once the buds are picked, the rooting ability will be weakened, or it will not take root at all, and even the existing roots may shrink, because leaves and roots are mutually restricted. The leaves of plants have the function of evaporating water, and the evaporation of leaves promotes the rapid recovery of absorption by roots. If the leaves with evaporation function are lost, the water passage at the root will be blocked and the survival rate of the stump head will be reduced. (2) Shorten the time for the stump to leave the soil.

Generally, stumps are dug from Shan Ye, and the time is as short as three or four days, and as long as ten or eight days. If the stump is left for too long, the tree will only evaporate, and the phoenix will be dehydrated and withered easily. Therefore, we must seize the opportunity to plant them as soon as possible, so as to shorten the time for the stumps to leave the soil. Soil is the main source of plant nutrients. When planting new stumps and covering the soil, we should pay attention to air permeability and hydrophobicity, and gently compact the soil so that each root is closely connected with the soil, so that the soil will adhere to the root and the soil will stick to the root. Firstly, according to the needs of the stump, the soil is broken into small particles, and then the soil is divided into three types: coarse, medium and small. The thick ones are placed around the basin bottom and the master, and some small ones are placed on the tree heads. The roots of trees should not stick to the edge or bottom of the basin, and then cover small particles with a lot of soil, but the fill should not be too full. Then insert a small bamboo stick into the mud and shake it left and right to make it firm. Then put the basin into water, so that the water permeates from the bottom hole of the basin and rises to the basin surface; You can also sprinkle water from the surface of the basin, so sprinkle it enough and then put it in the shade for cultivation.
