Carbon fertilizer and preparation method thereof

Abstract

The embodiment of the present application provides a carbon fertilizer and a preparation method thereof. The carbon fertilizer comprises the following components: 5%-20% by mass of an amino acid, 10%-30% by mass of water-soluble organic carbon, 1%-8% by mass of water-soluble phosphorus, 1%-8% by mass of water-soluble potassium, and the balance of a medium; and the carbon fertilizer comprises 15%-50% by mass of organic matter, and 10%-20% by mass of total nitrogen. According to the carbon fertilizer provided by the embodiment of the present application, the carbon fertilizer is rich in microelements in addition to organic carbon, so that the fertilization and irrigation effects can be realized from a plurality of aspects, and the carbon fertilizer is suitable for use in a region with largeday-night temperature difference, and can achieve good fertilization and irrigation effects in a lower-temperature environment; and the fertilization and irrigation mode of the carbon fertilizer can be improved, harmful algae in a water body can be prevented from being increased, and the carbon fertilizer can play a role in purifying the water body, makes the water body more clear while realizingthe fertilization and irrigation effects, and is more suitable for growth of beneficial algae.

Description

technical field [0001] The present application relates to the technical field of fertilizers and their preparation methods. Specifically, the present application relates to a carbon fertilizer and its preparation methods. Background technique [0002] In the field of aquaculture, in order to increase the yield of fish and beneficial aquatic crops, as well as improve the breeding conditions, it is often necessary to improve the water body through manual intervention, so that the water body is more suitable for the growth of fish and beneficial aquatic crops. This artificial intervention can be done by adding fertilizers to the water body. There are many types of fertilizers that can be classified according to the ingredients they contain. [0003] Among them, carbon fertilizer is used to improve water body nutrients and provide organic matter sources for fish and beneficial aquatic crops. Some types of carbonaceous substances in carbon fertilizers are slightly soluble or ...
