Abstract

The invention relates to an integrated water and fertilizer applicator and a control method thereof. The integrated water and fertilizer applicator comprises a plurality of fertilizer-liquor tanks, a fertilizer mixer, an impounding reservoir and a central control device. An EC/PH detecting and monitoring device connected with an integrated controller is arranged in the fertilizer mixer. The impounding reservoir is connected to the fertilizer-liquor tanks and the fertilizer mixer through a water source booster pump. The fertilizer-liquor tanks are connected to the fertilizer mixer through a fertilizer mother liquor pump. The fertilizer mixer is connected to a main irrigation pipeline through a fertilizer pump. The water source booster pump, the fertilizer mother liquor pump and the fertilizer pump are correspondingly connected to the central control device through driving circuits. Fertilizer application parameters are preset through the central control device, the fertilizer mother liquor in the fertilizer-liquor tanks is injected into the fertilizer mixer through the fertilizer mother liquor pump, and the water in the impounding reservoir is injected into the fertilizer mixer through the water source booster pump. Whether the PH value and EC value in the fertilizer mixer are matched with preset values or not is detected, further the injection of the fertilizer liquor and the water is adjusted according to feedback to make the PH value and EC value of the fertilizer liquor in the fertilizer mixer matched with the preset values, and the mixture is output to a main irrigation pipeline through the fertilizer pump.

Description

technical field [0001] The invention relates to a water and fertilizer integrated fertilizer applicator and a control method thereof. Background technique [0002] Water and fertilizer integration precision irrigation and fertilization technology is a new agricultural technology that integrates irrigation and fertilization for precise irrigation and fertilization. With the help of the pressure irrigation system, the fertilizer solution blended with soluble solid fertilizer or liquid fertilizer and irrigation water are evenly and accurately transported to the root soil of the crops, and the water and nutrients during the whole growth period can be adjusted according to the growth needs of the crops. Quantitative, timing, supply in proportion. The realization of water and fertilizer integration precision irrigation and fertilization technology requires corresponding water supply, fertilizer supply, automatic precision irrigation and fertigation, irrigation pipe network and ot...
