Problems solved by technology

At present, the methods for measuring the solubility of solids mainly include the equilibrium method and the dynamic method. The measurement principle is simple, but the measurement process is cumbersome, and the temperature is not suitable for control. The measured solubility is quite different from the production requirement.

Abstract

The invention relates to a chemical fertilizer solubility measuring device, which comprises a holding tank, a container, a controller, a constant temperature box, a liquid suction device, a temperature sensor, a pH sensor and a weighing device. The method is as follows: put the storage tank filled with saturated fertilizer solution into the incubator, and heat the saturated fertilizer solution in the storage tank to the preset temperature; when the temperature sensor shows the set temperature and the pH sensor does not change, it will automatically Record the pH value at this time and the measured value m of the weighing device 0 , and then suck the saturated fertilizer liquid into the container, and automatically record the measured value m of the weighing device at this time again 1 ; Move the container to an incubator for heating and drying, and record the mass m of the container at this time 2 ;Calculate the solubility S of the fertilizer solution 1 =(m 2 -m 0 )100 / (m 1 -m 2 )(m 1 -m 2 ). It can measure the solubility of chemical fertilizers in different water sources under different temperature and different acid and alkali conditions.

Description

technical field [0001] The invention relates to the field of agricultural irrigation, in particular to a chemical fertilizer solubility testing device and method. Background technique [0002] In the integrated technology of agricultural water and fertilizer, fertilizers need to be dissolved in irrigation water to supplement water and nutrients to crops. There are four main factors affecting fertilizer solubility: (1) water temperature; (2) acidity and alkalinity of water; (3) pressure; (4) type of fertilizer. Due to different water source conditions, after dissolving the same amount of fertilizer, the acidity and alkalinity of the fertilizer solution are very different, and the effects on crops are also different. Even with the same water source conditions, due to different irrigation times and water temperatures, the effects on fertilizer solubility are also different. However, the solubility of fertilizers that we usually know is a characteristic parameter under specifi...
