Water and fertilizer mixing device

Abstract

The invention relates to the technical field of water and fertilizer mixing and particularly relates to a water and fertilizer mixing device. A moisture content detecting device and a principal element detecting device are arranged in soil and are used for detecting moisture content and principal elements such as phosphorus, potassium and nitrogen of the soil, the concentration of a phosphate fertilizer, the concentration of a potassium fertilizer and the concentration of a nitrogen fertilizer are controlled through controlling rate of injection of water in the water and fertilizer mixing device by a control device, and too much or too little of water is prevented from being applied into the soil; through detecting the principal elements and controlling the amount of the nitrogen fertilizer, the potassium fertilizer and the phosphate fertilizer entering a mixing drum by the control device, excessive elements are prevented from being applied into land.

Description

Technical field [0001] The invention relates to the technical field of water and fertilizer mixing, in particular to a water and fertilizer mixing device Background technique [0002] In recent years, China has mostly adopted water and fertilizer integration technology in the field of agricultural fertilization. Its advantages are that the fertilizer efficiency of irrigation and fertilization is fast, and the nutrient utilization rate is improved. The water and fertilizer integration equipment in the existing technology provides water and fertilizer through a controllable pipeline system to make water and fertilizer. After the fusion, drip irrigation, uniform, regular, and quantitative irrigation of crop roots is formed through pipes and drippers, so that the main root soil is always loose and suitable for water content. However, most of the water and fertilizer integrated systems in the prior art only Fertilizer and water are mixed and evenly mixed and then irrigated into the so...

Problems solved by technology

[0002] In recent years, China has mostly adopted the integrated water and fertilizer technology in the field of agricultural fertilization. Its advantages are that the fertilizer efficiency of irrigation and fertilization is fast and the nutrient utilization rate is improved. After blending, pipes and drippers are used to form drip irrigation, uniform, regular, and quantitative irrigation of crop root development and growth areas, so that the main root soil always maintains looseness and suitable water content. However, most of the water and fertilizer integration systems in the prior art only The fertilizer and water are mixed and stirred evenly and then irrigated into the soil. It is not possible to determine the water content of the fertilizer to be applied according to the determination of the land, nor can it be determined according to the trace elements contained in the land. The specific application of various element fertilizers Ratio. At present, land fertilization is mostly applied to fertilizers such as phosphorus fertilizer, potassium fertilizer, and nitrogen fertilizer. In the prior art, fertilizers of various elements are mixed together and applied to the land, which causes waste of fertilizers, and excessive application of nitrogen fertilizers will cause organic matter. Low content will affect the activity of microorganisms. Excessive application of phosphorus fertilizer will destroy the soil aggregate structure and cause soil compaction. Excessive application of potassium fertilizer will destroy the bond bridge of soil aggregate structure. The existing technology cannot apply the corresponding proportion according to the specific needs of the land. fertilizer
