A water and fertilizer mixing device

Abstract

The invention relates to the technical field of water and fertilizer mixing, specifically 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 detected. The control device controls the injection amount of water in the water and fertilizer mixing device to control the concentration of phosphate fertilizer, potassium fertilizer and nitrogen fertilizer, and prevents too much or too little water from being fertilized in the soil. The control device controls nitrogen fertilizer, potassium fertilizer and phosphate fertilizer to enter the mixing The amount of buckets, so as to prevent too much of the above elements in the soil.

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 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 la...

[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
