MICRO-CARBON FERTILIZER FOR DECREASING AMOUNT OF CHEMICAL FERTILIZER, INCREASING BOTH QUALITY AND YIELD OF CROP, AND IMPROVING SOIL, AND PREPARATION METHOD AND APPLICATION THEREOF

摘要

Provided are a micro-carbon fertilizer for decreasing the amount of chemical fertilizer, increasing both the quality and yield of crops, and improving soil, and a preparation method and an application thereof, wherein the formulation composition of the micro-carbon fertilizer by mass percent is: 35-50% of micro-carbon (abbreviation for micromolecular water-soluble carbohydrates) with a particle size of 80-200 μm, 10-20% of amino acids, 15-25% of diammonium hydrogen phosphate, and 5-40% of potassium sulfate. The preparation process is as follows: raw materials: humic acid, amino acids, diammonium hydrogen phosphate and potassium sulfate; biodegrading raw materials: degrading humic acid into micro-carbon; placing semi-finished products into a jar: extracting the micro-carbon with a particle size of 80-200 μm according to quality standards, and placing same into a jar for storage; formulating and mixing ingredients; and checking and finishing the product. The use of micro-carbon can not only provide nutrients and energy, but can also improve the function of the soil. Where the amount of chemical fertilizer is reduced by 30%-50%, an improvement in the soil and an increase of above 30% in the quality and yield of the crops are realized.
