A kind of control method of water and fertilizer mixing device

Abstract

The present invention relates to the technical field of water and fertilizer mixing, in particular to a control method of a water and fertilizer mixing device. By setting a water content detection device and a main element detection device in the soil, the water content of the soil and the main elements such as phosphorus, potassium and nitrogen are determined. Detection, through the control device to control the injection of water in the water and fertilizer mixing device to control the concentration of phosphorus fertilizer, potassium fertilizer and nitrogen fertilizer, to prevent too much or too little water fertilized in the soil, through the detection of main elements, the control device controls the concentration of nitrogen fertilizer, potassium fertilizer, The amount of phosphate fertilizer that goes into the mixing bucket, so as to prevent too much of the above elements from being applied to the land.

Description

technical field [0001] The invention relates to the technical field of water and fertilizer mixing, in particular to a control method of 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. After the integration, the drip irrigation, uniform, regular and quantitative irrigation of the crop root development and growth area is formed through the pipeline and the dripper, so that the main root soil is always loose and has a suitable water content. Fertilizer and water are mixed 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 to determine the specific application of various element...

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
