New technology for chemical fertilizer intubation

May 23, 2024

The cannula is made of a plastic tube with a length of 20 cm to 25 cm, a diameter of 2 cm to 3 cm, and a wall thickness of 3 mm to 5 mm. The bottom of the plastic tube is made into a conical shape (for easy insertion into the soil) in the plastic tube. The surrounding (including the lower cone) is evenly drilled into small round holes with a diameter of 1 mm to 2 mm. The top of the plastic pipe is made of a slightly larger plastic pipe to prevent rainwater from dripping into the pipe and preventing the fertilizer from volatilizing. After the intubation principle of the fertilizer intubation and the method of use are made, the nitrogen, phosphorus, potassium and micro-fertilizer can be rationally mixed according to the different requirements of different crops for chemical fertilizer elements according to the principles of light nitrogen, heavy potassium and micro-increasing ( Under normal circumstances, the nitrogen, phosphorus, potassium fertilizer can be mixed in a ratio of 8%:12%:5%), and then inserted into the cannula, and then capped, and then the plastic tube is inserted into the soil 5 cm to 10 cm from the root of the crop. Medium (to avoid the moisturizing decomposition of the fertilizer to burn the roots of the plant); the top of the plastic pipe to expose the soil 3 cm ~ 5 cm is appropriate, in order to extract the plastic pipe to view or change the compound fertilizer. When a plastic cannula containing compound fertilizer is inserted into the soil, the water contained in the soil can gradually penetrate into the plastic tube through the small round hole of the cannula to moisturize and decompose the fertilizer, and the chemical decomposition product continuously flows to the soil through the small round hole. Transmitted for crop growth. Use effect and precautions Fertilizer intubation technology is mainly applied to woody, vine and other crops. When using, different fertilizer formulas should be selected for different needs of different plant elements. The fertilizer intubation technology has the characteristics of simple production, high efficiency of fertilizer efficiency, reusable intubation, easy operation, and can effectively reduce the input cost of chemical fertilizer, and the economic benefit is remarkable.
