In addition, the compound fertilizer is wide in raw material source, easy in raw material obtainment, multiple in nutrient category, high in nutrient content and good in water solubility, and can be applied to leaf surfaces in a dripping or spraying manner, thereby saving the labor cost and the fertilizer cost for peasants and improving the agricultural production efficiency.
Description
Technical field
The present invention relates to production technical field, particularly, relate to high nitrogen liquid composite fertilizer of a kind of protein liquid multi-nutrient element and preparation method thereof.
Background technology
China has become nitrogen fertilizer production state the biggest in the world, is also nitrogenous fertilizer country of consumption the biggest in the world simultaneously.The use of chemical nitrogen fertilizer is improving crop yield, is ensureing and brought into play great function aspect the grain security of China, but the excessive nitrogen of executing has formed serious nitrogenous source and pollutes.Especially in the production reality of the large leaf vegetables of nitrogen requirement, in order to satisfy crop to the demand of urea, the nitrogenous fertilizer such as a large amount of urea, carbon ammonium and ammonium nitrate are applied in the farmland, thereby have caused nutrient supply unbalance, reduce N fertilizer utilization rate, finally aggravated environmental pollution.
Another environmental factors that threatens human survival is that Freshwater resources are deficient so far, and particularly China is a large agricultural country, and agricultural production process has almost consumed 60 ~ 70% of Freshwater resources.Yet the efficient of agricultural water (WUE) is very low.Currently how to improve agricultural water use efficiency and utilize the utilising efficiency of the least possible high fertilizer of water extraction to be subjected to country and scholar's attention.Wherein fertigation technology has caused people's research interest once again.Advantage is applied for many years in China although the fertigation technology is because of its nutrient and efficiency of water application is high, less wastage, pollution are little etc.But drip irrigation and sprinkler irrigation fertilization technology are consistent in China for many years is take the higher water-soluble solid fertilizer of purity as the source of manure, be equivalent to will be common the water soluble fertilizer dissolving after pouring.Even this fertigation has many again advantages, be method and the technology of the common fertilising of simplification only, originally do not break through with it at fertilizer, do not give full play to technically the advantage of fertigation, namely not some functional liquid nutrients, together use as protein liquid.One direct reason is the impact that current fertigation technology is subjected to high solid photo-cured fluorine-containing polyurethane-acrylate coating traditional concept on the one hand, the manufacturers of fertilizer caters to user's popular product and causes fertilizer product without substantial improvements with manufacturing, on the other hand, difficulty due to the Production of manure technology, the research of the liquid fertilizer of China is in relatively backward state always, not only the compound manure of liquid form is few, and the functional liquid fertilizer of comprehensive utilization of resources still less.
segmentation and specialization along with social development and industry, a lot of originally irrelevant with agricultural, or be regarded as the thing of waste, as domestic refuse (animal fur, bone etc.) and trade waste (leather, workshop-sink) can with the fertilizer perfect adaptation, obtain the utilization of comprehensive reasonable and give full play to its trophism, not only solved the ecotope harm of these wastes, and bring into play wherein protein and amino acid whose effect, increase on the one hand soil organism improvement Soil structure, the opposing party improves the diversity of the nutritional condition increase soil microorganisms of soil microorganisms, thereby reach and not only apply fertilizer but also fertilizing soil ensures the effect of farmland quality.
Therefore above waste is processed, prepared pure protein liquid and is combined with fertilizer and fertigation to be fully utilized and have very important ecology, society and economic benefit.Simultaneously, in the supply nutrient, the various nutrient elements in protein liquid and amino acid have good promoter action to plant growth.Therefore, the application of protein liquid on the fertigation liquid fertilizer specially is produced, can effectively reduce the environmental destruction of above-mentioned industrial or agricultural and domestic refuse, and can realize effective combination of organic substance and mineral manure, long-term application will be improved physical structure, the biochemical property of soil to a great extent.As seen protein liquid multi-nutrient element liquid composite fertilizer is fertile for China's water saving, joint, for improving fertilizer and water use efficiency, significant for China's industrial or agricultural sustainable development, this type of liquid composite fertilizer has the huge market requirement in China, and protein liquid multi-nutrient element liquid composite fertilizer manufacturing technology can improve the international competitiveness of China's liquid fertilizer.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes existing liquid fertilizer, effectively utilizes various wastes, provides the good protein liquid of a kind of homogeneity, stability and suspension (being rich in multiple amino acids) multi-nutrient element high nitrogen liquid composite fertilizer.This compound manure contains protein, nitrogen, phosphorus, potassium and other elements of part, can satisfy the farming growth needs, and wherein nitrogenous fertilizer content is higher, is specially adapted to the high crop applying of nitrogen requirement.
