A micro-sprinkler irrigation and fertilization system integrating water and fertilizer

Abstract

The invention discloses an integrated water-fertilizer micro-jetting irrigation fertilizing system. The system comprises an irrigation system, a fertilizing system, a micro-jetting system and a control system. Filtering devices are arranged on many parts of the system so as to guarantee smooth irrigation; because of a stirrer, a heating wire and a temperature sensor, the safe and quick dissolution of chemical fertilizers is facilitated; the height can reduced by a lifting column when the fertilization is required so that the fertilizers are fully immersed into the soil and the good fertilizing effect is realized; the height can be properly increased by the lifting column when the fertilization is required so that water mist can be sprayed toward crops downwards from a high place, and therefore, the good moistening and irrigation effect is realized, and intelligent control management is realized.

Description

technical field [0001] The invention mainly relates to the field of micro-spray technology, in particular to a micro-spray irrigation and fertilization system integrating water and fertilizer. Background technique [0002] At present, micro-spraying technology is generally used for irrigation of crops in farmlands and greenhouses, but artificial fertilization is also very difficult. Therefore, the research on irrigation and fertilization is carried out at the same time, that is, the integration of water and fertilizer is realized; in actual operation, irrigation and fertilization are carried out at the same time The following problems will be encountered that have not been completely resolved: [0003] 1. The existing chemical fertilizers are generally solid, and it takes a lot of time to dissolve the chemical fertilizers to obtain a concentrated solution of chemical fertilizers before irrigation and fertilization; [0004] 2. The height of the sprinkler cannot be adjusted,...

Problems solved by technology

[0002] At present, micro-spraying technology is generally used for irrigation of crops in farmlands and greenhouses, but artificial fertilization is also very difficult. Therefore, the research on irrigation and fertilization is carried out at the same time, that is, the integration of water and fertilizer is realized; in actual operation, irrigation and fertilization are carried out at the same time The following problems will be encountered that have not been completely resolved:

[0003] 1. The existing chemical fertilizers are generally solid, and it takes a lot of time to dissolve the chemical fertilizers to obtain a concentrated solution of chemical fertilizers before irrigation and fertilization;

[0004] 2. The height of the sprinkler cannot be adjusted, that is, the height of the sprinkler cannot be adjusted by micro-spraying according to the height of the crop itself and irrigation or fertilization as the main purpose;

[0005] 3. Cannot realize intelligent micro-spraying
