Intelligent fertilizer applicator and fertilizer application control method

Abstract

The invention relates to the field of agricultural machinery, and in particular relates to an intelligent fertilizer applicator and a fertilizer application control method. The intelligent fertilizer applicator comprises a water pump, a main pipeline, a fertilizer supply branch, an acid supply branch and a controller, wherein a fertilizer supply pump and an acid supply pump are respective connected with the main pipeline through the fertilizer supply branch and the acid supply branch, and through control of the controller, the integrated control on fertilizer supply, acid supply and water delivery is realized; through a fertilizer concentration monitoring device, a pH value monitoring device and connection of the two with the controller, the information including the fertilizer concentration and the pH value of a work mixed solution can be accurately detected in real time, and the information can be fed back in time, so that the amounts of the fertilizer and the acid delivered by the fertilizer supply pump and the acid supply pump respectively can be accurately controlled, the fertilizer concentration and the pH value as well as a self-regulation system required for growth and regulation of crops are formed, and the healthy growth of fruits and vegetables is facilitated; through an impurity filter and a filtering mixer, blockage of the impurities to a mixed liquid control valve is avoided; and the whole fertilizer applicator is easy to operate and high in sensitivity.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an intelligent fertilizer applicator and a method for controlling fertilization. Background technique [0002] Soilless cultivation refers to a cultivation method that does not use natural soil but uses a substrate or only uses a substrate when raising seedlings, and irrigates with a nutrient solution after planting. Since soilless cultivation can artificially create a good rhizosphere environment to replace the soil environment, it can effectively prevent soil continuous cropping diseases and physiological obstacles caused by soil salt accumulation, and fully meet the needs of crops for mineral nutrition, water, gas and other environmental conditions. The basic material can be recycled, so it has the characteristics of water saving, fertilizer saving, labor saving, high yield and high quality. [0003] In the process of soilless cultivation, the good growth of fruits and v...
