A kind of refined crop fertilization system and nitrogen fertilizer fertilization method

Abstract

The invention discloses a refined crop fertilization system and a fertilization method. The fertilization system comprises an omnibearing movable platform as well as a fertilization device, a detection device and a control device, which are all arranged on the omnibearing movable platform, wherein the omnibearing movable platform, the fertilization device and the detection device are controlled by the control device; the fertilization device comprises a fertilizer box, a liquid outtake pipe, a conveying pump, a drive device and a mechanical arm, wherein one end of the liquid outtake pipe is connected with the conveying pump, and the other end of the liquid outtake pipe is communicated with a jet rod; a plurality of jets are arranged on the jet rod; the conveying pump is communicated with the bottom of the fertilizer box via a pipeline and used for pumping the fertilizer into the liquid outtake pipe; the drive device is connected with the conveying pump and used for driving the conveying pump to operate; the jet rod is fixed on the mechanical arm; the detection device comprises a binocular camera and a spectrograph both fixed on the mechanical arm. The invention further discloses a refined crop nitrogenous fertilizer fertilization method. According to the invention, the information on characteristics of crops can be comprehensively analyzed via the binocular camera and the spectrograph, so that refined fertilization is achieved, and meanwhile, the structure is simple, and the jet fertilization is more flexible.

Description

technical field [0001] The invention relates to a fertilization device, in particular to a refined crop fertilization system and a nitrogen fertilizer fertilization method. Background technique [0002] Fertilizer is the chemical substance with the largest investment in agricultural production, and its expenditure accounts for about 50% of its production expenditure. The contribution rate of chemical fertilizers to food accounts for about 40%. my country needs to feed more than 20% of the population with 7% of the world's land. The importance of chemical fertilizers is self-evident. [0003] The current season utilization rate of nitrogen fertilizer in my country is generally 30% to 35%, potash fertilizer is 35% to 50%, and phosphorus fertilizer is 10% to 20%, which are far lower than developed countries. For the chemical fertilizers not used in the current season, most of the nitrogen fertilizer is lost with the rain or becomes gas loss; the potassium fertilizer is absorbe...

Problems solved by technology

[0011] The above-mentioned motorized sprayer for automatic target variable application can also be used for fertilization. Although it can judge the presence or absence of objects and some characteristic information of the target object according to the image monitoring device, and carry out variable application and fertilization, the amount of information provided by the image is extremely high. limited, it is not possible to analyze the conditions of the elements required by the crops, and the positions of the spray rods and nozzles in this invention are fixed, and it can only be sprayed in a limited area directly in front of it. , The position of the nozzle is readjusted and fixed

[0012] In addition, in the process of fertilization such as nitrogen fertilization, the existing fertilization methods are to estimate the approximate amount of nitrogen fertilizer application according to the area of ​​the plot, and then spray it on a large area. However, even in the same plot, there are differences between different plants. The actual amount of nitrogen fertilizer required is also different due to the difference in growth. If spraying uniformly, it is easy to cause some plants to have too much nitrogen fertilizer, while some plants have insufficient nitrogen fertilizer, and the nitrogen fertilizer spraying is unreasonable. Therefore, it is necessary to propose A fertilization method for spraying according to the individual differences of plants and crops
