The supplier of Congsheng White Wax said that in order to ensure the survival of large white wax tree transplantation, in addition to the preparation before transplantation and the application of scientific transplantation techniques, daily maintenance and management within 1 to 3 years after transplantation is very important, especially the first one after transplantation. The year is the top priority. In addition to requiring the implementation of routine management and protection work such as watering (spraying) water, drainage, tree trunk wrapping, moisturizing and anti-freezing, sheltering and shading, and pest control, the following measures must be adopted to promote the survival of transplanting.
1. Canopy spray or water drop on trunk
Set up a tripod on the south side of the canopy, and install a spray device 1m above the canopy. Since most of the south wind blows in summer and autumn, installation in the south can often spray the canopy to keep the branches and leaves of the forest moist, increase the air humidity around the trees, lower the temperature, and reduce the consumption of water and nutrients in the trees. Suppliers of clumping pewter can use the “drip irrigation method”, that is, put a tripod next to the tree and hang a water storage bucket on it, or directly hang the water storage bucket on the top of the tree, punch a few holes in the bottom of the bucket, and use silica gel to connect the small plastic tube One end is glued to the hole, the other end is sealed with fire, and the small tube is spirally wound around the trunk and branches, and then the plastic tube is punched to drip water. This method can also play a role in moisturizing and cooling, reducing water and nutrient consumption in the tree, and it is relatively simple and easy to implement.
2. Suppliers of clumping white wax promote the ventilation of root soil
After ash planting, the root soil has good permeability conditions, which can promote wound healing and promote the growth of new roots; the roots of ash trees have poor air permeability, such as deep planting, thick soil ball coverage, heavy soil and heavy roots. Factors such as stagnant water will inhibit the respiration of the root system, making the root system unable to absorb nutrients and water from the soil, leading to dehydration and wilting of plants, and severe root death due to rotten roots. In order to prevent water accumulation in the roots, improve soil permeability, and promote rooting, the following measures can be adopted: First, replace the soil. For the clay heavy soil with poor air permeability and easy accumulation of water, a deep trench can be opened at a distance of 20 to 30 cm from the periphery of the soil ball, and then the perlite with good permeability and water retention is filled into the trench until it is level with the ground. Second, dig drainage ditches. For areas with a lot of rain, heavy rainfall, and easy accumulation of water, the drainage ditch can be dig deep, the ditch is deep below the bottom of the soil ball, and the drainage is required to be unblocked. Third, bury the PVC pipe. Buried a few PVC pipes around the soil ball and punched a lot of small holes in the pipes. Usually pay attention to check whether the small holes are blocked. If there is water in the pipes, drain them away in time. This not only eliminates stagnant water, but also increases the air permeability of the soil.
3. Spray antitranspirant
Antitranspirant refers to a class of chemical substances that act on the surface of tree leaves to reduce transpiration intensity and reduce water loss. According to different modes of action and characteristics, they can be divided into three categories.
Measures for Promoting Transplantation Survival of Big Ash Trees
(1) metabolism: also known as stoma inhibitors. After it acts on the stomata guard cells, it can reduce or close the stomata, increase the stomata transpiration resistance, and reduce water transpiration. Common metabolic antitranspirants include phenylmercuric acid, abscisic acid, atrazine, alachlor, fulvic acid and so on.
