The fruit tree infusion method is an agricultural new technology that is based on the principle of human infusion in the production practice of fruit growers. It has the advantages of less investment, easy to grasp and promote, saving water, saving fertilizer, saving medicine, saving labor and quick effect. The specific method is: Equipment preparation. Use a 1.5-liter plastic beverage bottle and a disposable medical infusion tube. Disinfect with potassium permanganate solution. Rinse with water and dry. Infusion method. Fill the plastic bottle with the instilled liquid and hang it at 1.5 meters (the trunk is strong. Branches above and below 1.5 meters can be directly hung on the branches. In addition, a wooden stake can be placed next to the young tree to hang the bottle). . Use a hole punch to drill a hole about 5 mm in diameter on the tree trunk and about 10 mm deep into the wood. Insert the needle from the bottom up and obliquely into the xylem in the hole to form a layer. Use the controllable switch on the infusion tube to control the drip rate. The speed and quantity of drip should be determined according to the size of the tree and the concentration and species of the drip. Liquid preparation. Clear water: According to the size of the tree, each tree once infusion of 1 to 2 liters. Nutrient solution. According to the top dressing concentration of fruit trees, add fertilizer in clean water. Insecticides and bactericidal liquids: For the control subjects, add appropriate concentrations of internal absorption-conducting counterpart pesticides in clean water. Simple drip method benefits. The first is direct water injection, which is conducive to drought-fighting and seedling protection and can ensure the water needed for trees during drought. Every 10 days, each tree is transported with 2-20 kg of water, which is equivalent to 100-500 kg of irrigation, saving more than 90% investment in irrigation. Secondly, direct fertilizer application (foliar nitrogen fertilizers that are easily soluble in water and without precipitation are more suitable, and 5% for unhatched fruit, and 10% to 20% for fruit that has already been fruited) can promote tree growth. To ensure the nutrient needs of different growth periods. According to the formula, 50 grams of urea is delivered at a time, which is equivalent to spreading 2.5 kilograms on the ground. The third is direct injection (the injected pesticide should be easily soluble in water, no precipitation, should be lower than the direct spraying concentration, about one-third of the direct spraying concentration is appropriate), can better kill the trunk Inside and leaf pests. Using the infusion method to control pests not only saves 65% of pesticides, but also saves labor. This simple drip method, applied in arid regions, is conducive to improving the survival of newly planted saplings and promoting the growth of trees. It can be implemented on a large scale, and it can also facilitate single-family households to implement scattered trees.
