Fertilizer intubation technique
Intubation production: take a plastic tube with a length of 20 to 25 cm, a diameter of 2-3 cm, and a wall thickness of 3-5 mm. Make the bottom of the plastic tube conical (easy to insert into the soil), around the plastic tube ( The lower end cone is uniformly drilled into a small circular hole having a diameter of 1-2 mm. The top of the plastic pipe is made of a slightly larger plastic control, and the cover (which can be wrapped with a cover of the agricultural film cover) to prevent rain from dripping inside the pipe and preventing the chemical fertilizer from volatilizing.
Principle and application of fertilizer intubation: after intubation. According to different plants (crops), the demand for fertilizer elements is different. According to the principle of light nitrogen, heavy potassium and micro-fertilizer, the nitrogen, phosphorus, potassium and micro-fertilizers are reasonably mixed (in general, the nitrogen, phosphorus and potassium fertilizers can be mixed according to the ratio of 8%:12%:5%). Installed in the cannula, the roots are 5-10 cm in the soil (to avoid the roots of the plant by chemical fertilizer); the top of the plastic tube is suitable to expose the soil 3 to 5 cm, so as to facilitate the extraction of plastic tubes to view or replace the mixed fertilizer. When the plastic cannula containing the 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 is continuously flowed through the small round hole source. Transferred in the soil for the growth of plants (crops).
Use effect and precautions: Fertilizer intubation technology is mainly applied to woody, vine and other plants. When used, different fertilizers should be mixed for different needs of different plant elements. The fertilizer intubation technology has the characteristics of simple production, high fertilizer efficiency utilization, reusable intubation, easy operation, and effective reduction of chemical fertilizer input cost, and significant economic benefits.
