High-nitrogen fluid compound fertilizer containing multiple protein fluid nutrient elements and preparation method thereof

Abstract

The invention discloses a high-nitrogen fluid compound fertilizer containing multiple protein fluid nutrient elements and a preparation method thereof. The compound fertilizer comprises 29 to 44 parts of suspending agent, and 71 to 56 parts of nitrogen, phosphate and potash fertilizers, wherein the suspending agent comprises the following components in parts by weight: 2 to 7 parts of hydroxyethyl cellulose, 2 to 5 parts of sodium bentonite and 25 to 32 parts of protein fluid. According to the compound fertilizer, proteins in household garbage and industrial waste materials (fluids) are utilized effectively; and the prepared nitrogen fluid is good in stability and homogeneity and capable of providing a large number of elements and organic nutrients for crops, so that the fertilizer utilization rate is improved. 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 [0001] The invention relates to the field of production technology, in particular to a protein liquid multi-nutrient element high-nitrogen liquid compound fertilizer and a preparation method thereof. Background technique [0002] my country has become the world's largest nitrogen fertilizer producer and also the world's largest nitrogen fertilizer consumer. The use of chemical nitrogen fertilizers has played a huge role in increasing crop yields and ensuring my country's food security, but excessive nitrogen application has caused serious nitrogen source pollution. Especially in the actual production of leafy vegetables that require a lot of nitrogen, in order to meet the needs of crops for urea, a large amount of nitrogen fertilizers such as urea, ammonium bicarbonate and ammonium nitrate are applied to farmland, resulting in an imbalance of nutrient supply and reducing the nitrogen fertilizer production. utilization rate, which eventually aggravated enviro...

AI Technical Summary

Problems solved by technology

One direct reason is that the current fertigation technology is affected by the traditional concept of high-solid light-curing fluorine-containing polyurethane-acrylate coatings on the one hand, and fertilizer manufacturers have no substantial improvement in fertilizer products by manufacturing popular products that cater to users. On the one hand, due to the difficulty of fertilizer manufacturing technology, the research on liquid fertilizers in my country has been in a relatively backward state. Not only are there few compound fertilizers in liquid form, but there are even fewer functional liquid fertilizers for comprehensive utilization of resources.
