What do you need to pay attention to when transplanting sweet-scented osmanthus? Ask experienced netizens to help introduce the transplanting of sweet-scented osmanthus trees if improper methods will make the survival rate of sweet-scented osmanthus trees low, resulting in unnecessary losses, the planting network sorted out the key points of sweet-scented osmanthus transplanting, listed below for netizens' reference and study. First, the choice of transplanting season: Osmanthus fragrans transplanting time is too early, the temperature is high, transpiration is large, the root system is easy to be damaged, the ability to absorb water is weakened, often resulting in fallen leaves or even death. Because most of the sweet-scented osmanthus trees are transplanted from the south, the time is too late and there is no transition stage, can not adapt to the northern climate, easy to freeze to death. Even if the survival is a few backbone branches, the branches and leaves are sparse, which can not achieve the effect required by the project. After groping, the best time for sweet-scented osmanthus trees in Zhengzhou is mid-November. At this time, the temperature began to drop, the transpiration was small, the ground temperature was high, and the wound of the injured root system healed quickly. At the same time, the root can grow some capillaries, alleviate the lack of nutrient absorption capacity, and ensure the smooth winter of sweet-scented osmanthus trees. Second, the choice of transplanting trees: to choose sweet-scented osmanthus trees with full shape, luxuriant branches and leaves, no diseases and insect pests, easy to dig and lift. Third, the preparation of sweet-scented osmanthus before transplanting: 1, the preparation of cultivation pit: the tree pit of the newly planted land should be dug about a week before transplanting, and the diameter of the pre-excavated tree pit is about 1 meter larger than that of the transplanted tree (convenient for workers to operate in the pit). Height and transplanting packaging height level. The excavated topsoil and the subsoil are placed separately, spread out to dry, and clean up the bricks, tiles and other impurities in the soil. According to the mixture ratio of 10 ∶ 1 (10 parts of soil), ferrous sulfate was mixed to increase the acidity of the soil, disinfect the soil and enhance the fertility at the same time. 2. Pruning of sweet-scented osmanthus before transplanting: pruning of sweet-scented osmanthus is one of the keys to transplanting survival. Because the sprouting ability of sweet-scented osmanthus is not strong, it is not advisable to truncate and cut branches. You can only prune the leaves of sweet-scented osmanthus, cut them with scissors, leave petioles, protect axillary buds, and retain 1/3 of the original leaves. This can not only reduce the evaporation of water, but also retain the beauty of the original crown. Fourth, sweet-scented osmanthus seedling method and transport protection: 1, sweet-scented osmanthus seedling method: the transplanting of sweet-scented osmanthus with hard packaging is the best. The sweet-scented osmanthus trees to be transplanted should be watered once a week in advance to make their roots absorb enough water. In this way, it is easy to dig into balls, and the soil balls will not spread out because the soil is too dry. The diameter of the soil ball should be 6 to 8 times the crown diameter of the plant 1 meter above ground, and the height is 70% of the diameter of the soil ball. It is better to dig big under the condition. When excavating, remove the topsoil at the base of the trunk and dig into a square trapezoid according to the required diameter, the diameter of the lower mouth is 1 inch 3 of the diameter of the upper mouth, and the diameter of the earth ball is 5 to 10 cm larger than the diameter of the formwork (in order to tighten the soil ball with the formwork). While digging the earth ball, prepare the formwork, wire piercing (steel wire cover), iron wire, etc., in order to pack the earth ball in time after digging. The big roots that need to be cut off should be sawed off by hand saw instead of chopping with other tools. The cross section of the roots should be adjusted to paste with sulfur powder and ABT rooting agent according to the ratio of 3 ∶ 2. After digging the earth ball, buckle the formwork quickly, tighten it with thread, and the tree trunk is packed with grass rope and hoisted. 2. Transport protection of sweet-scented osmanthus: sweet-scented osmanthus is hoisted to the vehicle and placed upright, the soil ball is tied to death in a woven bag (the old soil of the earth-digging ball), and the crown is tightly wrapped in plastic film to prevent movement and shaking in the process of transportation. Fifth, sweet-scented osmanthus planting and later management: 1. Planting of sweet-scented osmanthus trees: before planting, it is necessary to transport the original soil brought back by sweet-scented osmanthus trees to 10-15 cm before planting. Because the sweet-scented osmanthus tree is not resistant to flooding, the depth of the planted sweet-scented osmanthus is 10 to 15 centimeters higher than the original ground. First of all, put the sweet-scented osmanthus tree in the direction of its original growth, and then put a plastic pipe in each of the four corners of the tree pit to increase the air permeability of the root after filling the soil. Then remove the formwork sequentially while backfilling to 1x3 of the height of the earth ball, fill the original soil close to the surroundings of the soil ball, and fill a solid layer to prevent the soil ball from breaking. All the tree pits are filled firmly, cofferdam, braced and watered for the first time. 2. Management of sweet-scented osmanthus after transplanting: first, water permeable again 3 to 4 days from the first watering. Second, after all the water is dry, the remaining soil around the original tree pit is surrounded by the roots to form a mound with high middle height and low surroundings, so that the sweet-scented osmanthus tree will not be drowned because of stagnant water. Third, the spring water must be watered once next spring. Fourth, the leaves and branches were sprayed with the mixture of potassium dihydrogen phosphate and fungicides (carbendazim, etc.) at an average temperature of about 20 ℃. It not only carried out foliar topdressing for sweet-scented osmanthus trees, but also played a role in sterilization. Click to get more sweet-scented osmanthus tree planting techniques
