Fertilizer distributor capable of fast measurement and intelligent dispensing

Abstract

Embodiments of the invention provide a fertilizer distributor capable of fast measurement and intelligent dispensing, and relate to the field of agricultural machinery. The fertilizer distributor comprises a frame, and a colter, a fertilizer storage box, a controller, a laser and a CCD image sensor that are arranged on the frame. The fertilizer storage box is internally provided with a solenoid valve, and the controller is in electrical connection with the laser, the CCD image sensor and the solenoid valve. The laser is used for outputting pulse laser to to-be-detected soil located on an upper surface of the colter so as to form a plasma spectrum excited on the surface of the to-be-detected soil; the CCD image sensor is used for converting the plasma spectrum to an electrical signal and sending the electrical signal to the controller; and the controller is sued for analyzing the received electrical signal to obtain the nutritive element content of the surface of the to-be-detected soil, and controlling the open degree of the solenoid valve according to the obtained nutritive element content of the surface of the to-be-detected soil so as to control the fertilizing amount. The fertilizer distributor enables the fertilizing amount to be accurately controlled, thereby improving the yield and quality of crops.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a fast-measurement intelligent formula fertilizer applicator. Background technique [0002] Fertilizer is an important material for agricultural development. It is an artificial supplement of nutrient elements for crops when the soil cannot provide the nutrients needed for crop growth and development. Unreasonable fertilization will not only fail to increase the yield of crops, but will lead to soil pollution. Source pollution, excessive heavy metals in the soil, severe eutrophication of water bodies, and large greenhouse gas emissions, so rational fertilizer application is an important way for sustainable agricultural development. At present, although there are a variety of fertilizer applicators for fertilization, precise fertilization cannot be performed, resulting in uneven fertilization and no drop in fertilizer amount, which not only affects crop growth, but also pollu...

Problems solved by technology

At present, although there are a variety of fertilizer applicators for fertilization, precise fertilization cannot be performed, resulting in uneven fertilization and no drop in fertilizer amount, which not only affects crop growth, but also pollutes the soil environment. For example, the application numbers are CN201520412466.2, CN201310662947.4, CN201510330824.X and other patents are mainly aimed at liquid fertilizers, fixed water and fertilizer mixing control machinery or methods, which can be used to fertilize according to the plant growth process, and cannot adjust the nutrient differences in the soil space for precise fertilization. Famous intelligence, but not intelligent

Therefore, when fertilizing, there will inevitably be too much or too little fertilization, which will affect the growth of crops and lead to a decline in the yield and quality of crops.

Due to the large spatial differences in soil, the traditional formula fertilization soil testing requires less sampling, and it is generally difficult to achieve accurate results.
