Abstract

The invention relates to a biogas slurry pretreatment method for a foliar fertilizer and a drip irrigation fertilizer, and the biogas slurry pretreatment method comprises the steps of pumping biogas slurry in a biogas slurry collection tank to a water distribution pipe arranged in a cobblestone layer in a biogas slurry pretreatment tank through a self-control device, evenly distributing the biogas slurry in a small broken stone layer through the water distribution pipe, then leading the biogas slurry to sequentially pass through a coarse sand layer, a fine sand layer and the cobblestone layer for collection and finally draining the biogas slurry into a biogas slurry mixing tank through a water outlet pipe. A device for the pretreatment method mainly comprises four parts of the biogas slurry collection tank, the control device, the biogas slurry pretreatment tank and the biogas slurry mixing tank, and the device can overcome the problem that when the biogas slurry is directly used as the foliar fertilizer and the drip irrigation fertilizer, the device is blocked, thereby realizing the automation of the biogas slurry treatment, realizing the automation of biogas slurry application and achieving the purposes of saving water, saving fertilizer, saving medicine and saving labor force.

Description

technical field [0001] The invention relates to a biogas slurry pretreatment method and device for foliage fertilizer and drip irrigation fertilizer, belonging to the technical field of rural organic fertilizers. Background technique [0002] Biogas slurry is the residue after anaerobic fermentation of high-concentration organic wastewater, livestock and poultry manure, crop straw, etc., and contains a variety of biologically active substances, such as amino acids, trace elements, plant growth stimulants, B vitamins, certain antibiotics, etc. , used as foliar fertilizer, can regulate crop growth and metabolism, supplement nutrition, promote growth balance, enhance photosynthetic ability, especially when applied to vegetables, can prevent and control diseases and insect pests, make vegetables taste good, high yield, and apply to fruit trees, which is beneficial to flower buds Differentiation, flower and fruit preservation, fast fruit weight gain, consistent maturity, good qua...
