Integrated automatic quantitative sprinkling irrigation and fertilization system

Abstract

The invention provides an integrated automatic quantitative sprinkling irrigation and fertilization system. The system comprises a fertilizer supply device, a mixing device, a conveying device and anatomizing device, wherein the fertilizer supply device is connected with the mixing device through a pipeline, the mixing device is connected with the atomizing device through the conveying device, the fertilizer supply device comprises a macroelement supply unit and a microelement supply unit, and the fertilizer supply device automatically controls supply through a PLC (Programmable Logic Controller) and introduces the fertilizer into the mixing device for mixing, so that quantitative addition and application are realized. According to the scheme, nutrient solutions can be automatically adjusted and prepared according to different growth periods of crops; and the disease and insect pest resistance of a seedbed and crops in the growth and development process is improved; the improvement ofthe growth and development capability of plants is facilitated, the automatic production is conveniently improved, the quantitative operation of the nutrient solution is realized, the pollution to the environment is conveniently reduced, the utilization rate of the nutrient solution is improved, the crop production period is effectively prolonged, and the production cost and the production laborforce are conveniently reduced.

Description

technical field [0001] The invention relates to crop production equipment, in particular to an integrated automatic quantitative sprinkler irrigation and fertilization system. Background technique [0002] Water and fertilizer integration technology is a new agricultural technology that integrates irrigation and fertilization. The integration of water and fertilizer is to use the pressure system (or the natural drop of the terrain) to mix the soluble solid or liquid fertilizer according to the soil nutrient content and the law and characteristics of the fertilizer requirement of the crop species, and mix the fertilizer solution together with the irrigation water. [0003] Water and fertilizer are supplied through the controllable pipeline system. After the water and fertilizer are mixed together, the spray irrigation is formed through the pipeline and the dripper, evenly, regularly and quantitatively, and infiltrates the growth area of ​​the root system of the crop, so that ...

Problems solved by technology

[0006] However, the device cannot regulate the use of macronutrients and micronutrients during use. At the same time, the demand for nutritional elements is different during the growth and development process. Therefore, it is particularly important to provide a system that can automatically adjust the supply of nutritional elements.
