Fertilizer mixing and spraying device for synchronously spraying roots and leaves in paddy field

Abstract

The invention discloses a fertilizer mixing and spraying device for synchronously spraying roots and leaves in a paddy field. The structure of the device comprises horizontal and vertical fertilizingcap cylinders, branch pillar cylinders, a swirling flow valve cap, a liquid guide pipe, a pressure regulating knob ring, a quick joint ring and a fertilizer storage groove. The device realizes the matching of the horizontal and vertical fertilizing cap cylinders and the swirling flow valve cap, ensures the uniform water and fertilizer covering effect of horizontal pressure watering caps on the roots of rice and vertical spraying column cap nozzles on the rice leaves during spraying, realizes the water and fertilizer mixing in the paddy field, and the fact that rice absorbs fertilizers conveniently when absorbing water is facilitated, and the overall water and fertilizer concentration is lower than the concentration of rice roots, so that the stability during transitional absorption is realized, and the phenomenon of insufficient nutrient absorption caused by high and low concentration confusion is avoided; the fertilizer droplet coverage rate of rice roots and leaves is improved through a pressurized column cylinder frame, the wrapping and output effect of water and fertilizers is ensured during mixed spraying, autonomous dilution and pressurized annular large-area irrigation effects are formed for the fertilizers, and a soil-fixing and liquid-sealing effect is further formed for the annular surface spraying of the rice roots.

Description

technical field [0001] The invention relates to a fertilizer mixing and spraying device for synchronous root and leaf watering in paddy fields, which belongs to the field of agriculture. Background technique [0002] Fertilization of paddy fields is a routine step in agricultural operations. Spraying or manual shoveling is often used to cover the effect, and manual shoveling is often over-covered. Therefore, equipment fertilization is a common and effortless working method to ensure uniform fertilization of paddy fields. effect, improve the overall output, the shortcomings of the current technology to be optimized are: [0003] In the paddy field of rice, the water is sufficient, and the fertilizer is too dry and thick during the fertilization process, which will cause the roots to be covered, and the flow of high and low concentrations will cause the rice nutrients to leak out, and the fertility effect cannot be fully absorbed, resulting in water loss and shriveling of the ...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a fertilizer mixing and spraying device for synchronous root and leaf irrigation in paddy fields, so as to solve the problem that in paddy fields of rice, the water is sufficient, and the fertilizer is too dry and thick during the fertilization process. The roots are covered, and the high and low concentration flow leads to the leakage of rice nutrients, which can not fully absorb the fertility effect, resulting in water loss and shriveling of rice roots, which interferes with the saturation of rice leaves and pulp grains, resulting in dry, wrinkled, and loose leaves. , thereby affecting the overall yield of the paddy field, resulting in uneven fertilization concentration, and artificial shoveling and covering will also affect the uneven size of the fertilizer block, resulting in full rice grains in some areas and low rice harvests in some areas when rice absorbs nutrients , a problem that interferes with the yield value of a normal overall harvest
