Embodiment Construction

[0027] 1. Preparation of biologically active liquid: take 14kg of agricultural product waste (such as soybean meal, wheat bran), 4kg of sucrose, 3kg of agar, and appropriate amount of biological bacteria, mix well and put it into the pool, inject 30kg of pure water, and extract the original solution after about 6 days of submerged fermentation Compounded to form a biochemical active liquid: the concentration is about 50%, containing amino acids ≥ 30%, fulvic acid ≥ 20%, active biological nitrogen ≥ 10%, and organic matter water-soluble potassium ≥ 5%.

[0028] 2. Prepare organic stock solution: take 1000kg of pure fresh human urine, first use disinfectant to disinfect the viruses and parasites carried in human urine, then put in deodorant to deodorize, add the biologically active liquid prepared in step 1 to fix nitrogen, press Put ferrous sulfate (accounting for two-thirds of the input content), magnesium oxide (accounting for one-half of the input content), calcium hydroxide ...

Abstract

The invention discloses an enzyme-controlled active liquid compound fertilizer and a preparation method. The enzyme-controlled active liquid compound fertilizer comprises 5-10% of biological organic matters, 20-30% of urea, 12-18% of calcium hydrophosphate, 10-15% of potassium chloride, 5-10% of liquid humic acid, 2-4% of calcium, magnesium and sulphur, respectively, 0.5-1% of ferrum, zinc, molybdenum, chlorine, boron and copper, respectively, 5-10% of a suspended dispersant, 5-10% of an assistant and biological bacteria. The field plot experiment verifies that the enzyme-controlled fertilizer has remarkable yield-increasing effect on wheat, corn and rice paddy with the rate of growth respectively reaching 16.6%, 15.3% and 10.5% which is remarkably higher than that of common fertilizer group. The fertilizer disclosed by the invention is simple in preparation process, and can be prepared to suit nutritional components and concentrations of plants to meet a certain growth demand of plants, and further can be mixed in use with other fertilizers.

Description

technical field [0001] The invention relates to a compound fertilizer and a preparation method thereof, in particular to an enzyme-controlled active liquid compound fertilizer and a preparation method thereof. Background technique [0002] At present, the international fertilizer consumption is developing in the direction of high concentration, compounding, liquefaction and slow effect. Due to its low production cost, high nutrient content, easy compounding, direct absorption by crops, convenient formula fertilization (balanced fertilization) and mechanized fertilization, liquid fertilizer has attracted more and more attention from various countries. [0003] my country is a water-scarce country. Water plays a decisive role in agricultural production. Water conservation and rational fertilization are the basic national policies of our country. The integration of water and fertilizer is the general trend. With the promotion of water and fertilizer integration, traditional co...
