Intelligent integrated fertilization system with capacity of biogas slurry application

Abstract

The invention relates to an intelligent integrated fertilization system with capacity of biogas slurry application. The system comprises a water and fertilizer blending module, a water and fertilizerfiltering module, a water and fertilizer conveying module, a field monitoring and control module and an intelligent control module, wherein the water and fertilizer blending module is used for diluting biogas slurry and testing soil for formulated fertilization to meet the nutritional requirement of crop growth; the water and fertilizer filtering module is used for filtering the diluted water soluble fertilizer and the biogas slurry; the water and fertilizer conveying module is used for sufficiently mixing the matched biogas slurry and water soluble fertilizer and conveying the mixture througha pipeline; the field monitoring and control module is used for monitoring field weather information and crop growth information; the intelligent control module can realize automatic generation of anapplication operating account and can automatically control operation of all the modules through neural network and deep learning. The water and fertilizer blending module, the a water and fertilizerfiltering module, the water and fertilizer conveying module and the intelligent control module are highly integrated to an integrated box, labor can be effectively saved, labor intensity is reduced,and the system operates stably, is suitable for various irrigation pipeline systems, can scientifically and efficiently apply the biogas slurry, fertilizer and water and improves irrigation quality and efficiency.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilization, in particular to an intelligent integrated fertilization system capable of applying biogas slurry. Background technique [0002] Biogas slurry contains a variety of nutrients for plant growth, rich in amino acids, various growth hormones and vitamins, and is a well-known quick-acting organic fertilizer. With the sustainable development of ecological agriculture, the use of biogas slurry is gradually being developed and utilized by people. At the same time, General Secretary Xi Jinping pointed out in his speech at the 14th meeting of the Central Financial and Economic Leading Group that it is necessary to accelerate the treatment and recycling of livestock and poultry farming waste; Guobanfa [2017] No. 48) pointed out that it is necessary to comprehensively promote the resource utilization of livestock and poultry breeding waste, build a new pattern of sustainable development t...

Problems solved by technology

[0003] At present, the overall structure of most biogas slurry fertilization devices is complicated, and the filtration system does not have the function of automatic backwashing. It requires manpower to clean the filter residue after biogas slurry filtration, which reduces the working efficiency of the fertilization device. The level of intelligence is low, the control is inconvenient, and wastes manpower. ;Traditional water and fertilizer integration technology is only suitable for the application of soluble solid or liquid fertilizers. There is no effective filtration method for biogas slurry with high solid content, which is difficult to meet the requirements of field drip irrigation and sprinkler irrigation equipment, and it is easy to block drip irrigation and sprinkler irrigation equipment. At the same time, The existing water and fertilizer integration facilities and equipment have poor compatibility and cannot meet the needs of various irrigation pipelines

Moreover, the long-term application of undiluted biogas slurry in the field can increase the organic matter content and fertilizer efficiency in the short term, but it will have an adverse effect on the seedling burning of economic crops at the seedling stage, and long-term application will cause great harm to the environment. If the biogas slurry is used Artificial dilution not only reduces work efficiency, but also increases labor intensity
