System and method for producing organic fertilizer from agricultural waste and applying organic fertilizer to water-fertilizer integrated application in orchard

Abstract

The invention provides a system and method for producing an organic fertilizer from agricultural waste and applying the organic fertilizer to water-fertilizer integrated application in an orchard. Thesystem is composed of a fermentation device, a water-fertilizer integrated application device, a drip irrigation device, an automatic control device and the like, wherein the fermentation device is composed of a fermentation tank, a solar heating device, a solar stirring and ventilating device, a feeding port, a slag removing port, an overflow pipe, a biogas collecting unit and the like; the water-fertilizer integrated application device is composed of a water pump, a solenoid valve, a top dressing barrel, a venturi tube, etc.; the drip irrigation device is composed of a main pipe, branch pipes, water droppers, etc.; and the automatic control device is composed of controller hardware, controller software, a series of sensors used for sensing temperature, soil moisture and the like, etc. The system of the invention can quickly alleviate contradictions between the increase in the demand for organic fertilizers of fruit farmers in economically developed areas and the shortage of the sources of raw materials caused by livestock ban, and solves the problems of resource waste, environmental pressure and treatment difficulties caused by agricultural waste and the problems of messiness and great consumption of time and labor in stacking of traditional organic fertilizers in orchards.

Description

technical field [0001] The invention relates to a system and method for producing organic bacterial fertilizer by using agricultural waste and applying it to an integrated application of water and fertilizer in orchards, belonging to the technical field of agricultural waste treatment. Background technique [0002] With the increasing level of modernization of life, organic food has been paid more and more attention by people. The cultivation of organic food depends on the content of soil organic matter. However, there are common problems in orchard planting in my country, such as low soil organic matter content, extensive composting of organic fertilizers, laborious application, and environmental pollution. In recent years, the prohibition of raising livestock in economically developed areas has limited the source of organic fertilizers. In order to alleviate the contradiction between the increasing demand for organic fertilizers by fruit farmers in economically developed ...

AI Technical Summary

Problems solved by technology

[0005] In view of the above problems, this design utilizes agricultural waste resource treatment to produce organic bacterial fertilizer, which reduces pollution sources for rural areas, achieves the purpose of recycling, harmless and recyclable, and also alleviates the shortage of raw materials caused by the prohibition of livestock breeding ; The use of distributed fermentation equipment, continuous pool anaerobic fermentation and aerobic fermentation technology can effectively inhibit the enrichment of harmful microorganisms in the soil, alleviate the contradiction between the supply and demand of organic fertilizer for fruit farmers, and realize the circular development of rural economy; use solar energy as fermentation tank Ventilation, stirring and heating provide energy, reduce waste discharge, and have significant significance for improving the supply of organic fertilizers in orchards, increasing soil organic matter content and the environment
