Water and fertilizer integrated fertilization technology for apples
Simple water-fertilizer integrated fertilization technology â‘ Fertilization: the method of double dilution is used. First use a small bucket to compound the compound fertilizer and water-soluble organic fertilizer, and then add it to the fertilizer storage tank. For a small amount of insoluble matter, directly bury it in the orchard. â‘¡ Assembly and preparation of equipment. Connect the high-pressure hose to the topdressing gun while connecting the pressure pump, and put the water inlet pipe with the filter screen, the water return pipe, and the other water outlet pipe with the stirring head into the fertilizer storage tank. Check the sealing of the pipe joints. Place the high-pressure hose along the rows of fruit trees to prevent the hose from kinking and crushing the pipe. Start the booster pump and adjust the pressure to begin fertilizer application. â‘¢ The fertilization area is in the area near the vertical projection extension of the fruit tree crown, and the fertilization depth is about 25-35 cm. According to the size of the fruit tree, each tree is punched with 4 to 16 topdressing holes, each hole is fertilized for 10 to 15 seconds, and the fertilizer liquid is injected to 1 to 1.5 kg. The distance between the two fertilizer injection holes is not less than 50 cm. According to the planting density, Topdressing fertilizing water for each tree 5-30 kg. Simple fertilizer and water integrated fertilization should pay attention to the orchards with weak tree potential, rot disease, ring rot, severe ulcerative dry rot (oiling point), and large amount of fruit hanging. For orchards that use farmhouse fertilizers in successive years, due to the large number of underground pests, pesticides can be added to the fertilizer water. For orchards with severe root rot, fungicides can be added to the fertilizer water. The application concentration is the same as the foliar spray. For particularly arid soils, water distribution should also be increased. For newly planted young trees, the fertilizer concentration should be reduced to 1/4 to 1/2 of normal conditions. (Chinese farmer) Kiwi Fertilization equipment Kiwi water and fertilizer integrated fertilization technology can be divided into simple water and fertilizer integrated fertilization and pipeline water and fertilizer integrated fertilization. Simple integrated water and fertilizer fertilization is the use of mechanical devices for spraying orchards in orchards, and fertilization guns are used to perforate fruit tree trays. Pipeline water and fertilizer integrated fertilization is based on the topography of the fertilized orchard to build a reservoir and spread facility fertilizer pipes for fertilization. The fertilization method first measures soil and fertilization, and samples the orchard soil every year. Based on the results of soil nutrient determination, combined with the characteristics of fertilizer requirements in different periods of kiwi, a specific fertilization plan is formulated. Second dilution was performed using the 2 dilution method. First use a small bucket to fertilize the formula, and then add it to the fertilizer storage tank. When adding the formula fertilizer for dilution, stir it thoroughly. When diluted, the ratio of fertilizer to water is generally not higher than 15%, and the high temperature season is not higher than 10%. In the area near the vertical extension of the fruit tree crown, the fertilization depth is about 25 cm. According to the size of the fruit tree, each tree is punched with 6-8 fertilizer holes, each hole is fertilized for 5-8 seconds, and the fertilizer is injected with 1.5-2 kg of fertilizer. The distance between the two fertilizer injection holes is not less than 60 cm. Fertilizing water is 12.5 to 15 kg. Pipeline water and fertilizer integrated fertilization, each fruit tree has 4 drip tubes, each drip tube produces about 0.4 kg of fertilizing water per minute, fertilizing for 15 minutes, ensuring that each fruit tree tops up with 20 kg of fertilizing water. Precautions (1) Determine the amount of liquid fertilizer application according to the size of the tree and the amount of fruit hanging. Do not increase the concentration of fertilizer without permission to prevent root burning. (2) For orchards with underground pests, pesticides can be added to the fertilizer water, and for orchards with root rot disease, fungicides can be added to the fertilizer water. (3) If a fertilizing gun is used for fertilization, the pressure of the booster pump can be adjusted to about 2.0 to 2.5 pressures. If two guns are used for simultaneous fertilization, the pressure can be adjusted to 2.5 to 3.0 according to the actual situation of the high pressure hose pressure.
