The DC motor driver is connected to the DC motor; the DC motor is connected to the screw conveying mechanism; the screw conveying mechanism is connected to the fertilizer box through the fertilizer pipe; the display control unit includes a touch screen and a liquid crystal display; the display control unit and the main control unit Use serial port connection for data communication. The invention solves the problem of accurately controlling the amount of fertilization.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a precision fertilization control device for rice transplanters. Background technique [0002] It is impossible for all types and forms of chemical fertilizers applied in farmland to be absorbed and utilized by plants. Fertilizer utilization rate is 30∽60% for nitrogen, 3∽25% for phosphorus, and 30∽60% for potassium. If the amount is too large, or the use is normal, but due to other natural or man-made reasons, a large amount of chemical fertilizers will be lost. Nitrogen compounds that are not used by plants in time, if they cannot be absorbed by soil colloids, will be transferred below the dense distribution of plant roots when soil water seeps downwards, causing pollution. [0003] Environmental problems caused by chemical fertilizer pollution mainly include: eutrophication of rivers, lakes, and inland seas. The cause of eutrophication in water areas is mainl...
