Intelligent preparation method of liquid slowly-controlled-release fertilizer

Abstract

The invention discloses an intelligent preparation method of a liquid slowly-controlled-release fertilizer. A sensing module senses whether adding weights of raw materials reach preset values or not. A temperature detection module detects the temperature in a fourth stirring apparatus. A ventilation detection module detects the ventilation degree in the fourth stirring apparatus. A pH detection module detects the pH value of a solution. A PLC, according to the sensed values, the temperature value, the ventilation degree and the pH value, controls an electromagnetic valve, a grinding module, a stirring module, a sugar / water proportion module, an air blowing module, a temperature control module, the ventilation detection module, a reminding module, a heating module, a material module, a refrigerating module, a drying module, a crushing module, a filter module, a vibration module, a concentration module and a cooling module to execute related operations through internal analysis and calculation. By accurate control on various parameters, the intelligent preparation method effectively improves stability of a slow-release microelement chelating agent and a slow-release micro-crystallized metal salt mineral powder, so that the method is high in production efficiency, satisfies production demand, reduces labor intensity and provides accurate and reliable detection.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to an intelligent preparation method of liquid slow and controlled release fertilizer. Background technique [0002] The input of fertilizer plays a vital role in the yield of crops, but in the actual planting process of crops, there have been problems of single and excessive fertilization for a long time, and the average utilization rate of fertilizers is very low. The main reason is that the quick-acting fertilizers Sexuality and volatility. The corresponding measures are to use slow-release coated fertilizers to improve nutrient utilization, but the strength of the single-layer coating is low, the proportion of slow-release nutrients is fixed, and there is no specificity. The demand for nutrients restricts its own development. [0003] At the same time, in the preparation process of fertilizers, slow-release microbial agents, slow-release trace element chelating agents, and slow...

[0002] The input of fertilizer plays a vital role in the yield of crops, but in the actual planting process of crops, there have been problems of single and excessive fertilization for a long time, and the average utilization rate of fertilizers is very low. The main reason is that the quick-acting fertilizers volatile and volatile

The corresponding measures are to use slow-release coated fertilizers to improve the utilization rate of nutrients, but the strength of the single-layer coating is low, the proportion of slow-release nutrients is fixed, untargeted, and the demand for nutrients restricts its own development.

[0003] At the same time, in the preparation process of fertilizers, slow-release microbial agents, slow-release trace element chelating agents, and slow-release microcrystalline metal salt ore powder all play an indispensable role, directly affecting the quality and nutrients of fertilizers; If it is a mass production, the slow-release microbial agent, slow-release trace element chelating agent and slow-release microcrystalline metal salt ore powder also need to be produced in large quantities, but at this stage, the slow-release microbial agent, slow-release trace element The preparation of chelating agent and slow-release microcrystalline metal salt ore powder mostly relies on manual operation, which has low efficiency and low degree of automation, which brings inconvenience to operation and wastes resources
