The Renmin Road in Hengshui, Hebei Province, is the main artery that runs through the east and west. In the middle, there are two isolation belts occupying a width of about 10 meters. Because the roads of many vehicles are poor, the municipal Party committee and city government remove the middle isolation belt and sort out the old sidewalks. During the construction, the excavator was used to clear the ground and level the high ground, and then padding with lime soil and compaction. However, some lateral roots of the ash trees were inevitably wounded during operation, and the tree holes were left after 1.5 m square. In the near future, the growth of several hundred trees was affected and yellow leaves and fallen leaves appeared during the growing season. As a result, the Hengshui Garden Bureau decided to infuse the ash tree with fresh blood for it to promote the renewal of the ash tree and restore vitality. The following describes the specific operation method of tree infusion. Prepare materials Electric drills, spatula, nails, hammers, pliers, watering cans, bactericides, and nutrient solutions (such as "Big Tree Shita Live"). Infusion procedures and methods Before punching, prepare to scratch the old skin with a spatula at 20 cm to 30 cm above the root neck of the plant to expose new skin. The number of infusion holes should be matched with the size of the tree. The big tree has a breast diameter of 10 cm to 20 cm, two skins, 20 cm to 30 cm, four skins, and 30 cm or more, 6 skins, each phase. The adjacent holes are staggered about 5 cm above and below, that is, the holes are evenly swung open on two horizontal planes. This is for faster and better absorption during infusion. The hole diameter of the perforated infusion hole should match the diameter of the infusion plug, and the hole should be drilled with a drill in the area where the skin is peeled. The drill bit should be slanted down to 45 degrees and the depth should be kept between 3 cm and 5 cm. The sawdust should be carried out with an electric drill. . Install the infusion device and hammer the nail with a hammer 1.3 meters above the hole. Attach the nutrient solution such as active agent on the nail and insert the infusion set when the liquid flows out. Infusion of a bag of nutrient solution usually takes 3 to 5 hours to complete. Some of the nutrient solution is lost very slowly. It is necessary to timely re-drill the hole with an electric drill and change the infusion set to a new hole. The old hole is inserted with a small wooden stick that has been cut, sprayed with a sterilizer (75% chlorothalonil wettable powder 300 times) with a spray can, and then applied to the orifice with a bactericide solution and mud. After removing the infusion device and sealing liquid flow, remove the infusion set, insert a small wooden stick into the hole, spray the fungicide at the orifice, and then apply the fungicide and mud to the orifice. Remove the infusion bag, remove the nail with a pair of pliers, and apply the mud containing the disinfectant to the nail eye to prevent bacterial infection. Collecting infusion devices Keep all non-disposable equipment previously used and stored for reuse. Conclusion The tree infusion is a new type of garden treatment technology. The principle is the same as the human infusion. They are all for the purpose of supplementing the nutrients to maintain normal metabolism, have direct efficacy, and have less pollution to the environment. The nutrient solution contains the nutrients needed for the growth of the tree, activates the cell activity of the big tree, and provides active substances for growth of large trees, such as a variety of beneficial biological flora, organic peptides, boron, zinc, magnesium, iron, molybdenum and other trace elements. , And it is beneficial to add moisture to the big tree. The liquid medicine is fed directly from the catheter to the center of the trunk, and the trees are easily absorbed, increasing the restoring power of the tree vigor. At the same time, the nutrient solution contains bactericidal components that can prevent disease in large trees. Hengshui City Garden Bureau gave 613 yellow leaves and defoliated ash trees to infusate. The nutrient solution was lost every two months. It lost three times within six months. None of these trees died, and they have shown good growth and restored their vitality.
