specific Embodiment

[0030] 1. Application of decomposed products in organic fertilizers

[0031] The decomposed product of this method has an organic matter content greater than 15%, a humic acid content greater than 6%, and a total nitrogen content greater than 4%. In addition, it contains a variety of medium and trace elements and seaweed active substances, which can be used as one of the raw materials for organic fertilizers. The amount can be added arbitrarily to make organic fertilizers with different nutritional ratios.

[0032] 2. Application of decomposed products in agricultural microbial fertilizer

[0033] The decomposed product of this method is rich in nutrients, contains the active substance produced by the complex enzyme system in the enzymatic hydrolysis kelp residue, and the plant growth regulating factor in Enteromorpha, which can strengthen the activity of beneficial microorganisms, and it can be used as a carrier of bacterial fertilizer to effectively improve bacterial growth....

Abstract

The invention provides a method for promoting high efficiency decomposition of enteromorpha powder by using enzymatically hydrolyzed sea-tangle residues and application of a product. According to the invention, dried enteromorpha powder is used as a raw material; a solid microbial inoculum is selected; enzymatically hydrolyzed sea-tangle residues of different levels are added; promotion effects of different addition amounts of the enzymatically hydrolyzed sea-tangle residues of different levels on high efficiency decomposition of enteromorpha powder are researched under same culture conditions; an appropriate additive for aerobic composting of enteromorpha powder is provided so as to improve the utilization rate of enteromorpha powder. The method provided by the invention enables decomposition time to be shortened by 1/3, allows the content of organic matters and the content of humic acid to be increased by 2 to 3 times, respectively, greatly improves a decomposition effect and decomposition efficiency and creates conditions for application of a decomposition product in a fertilizer.

Description

technical field [0001] The invention belongs to the technical field of high-value decomposing and utilization of large seaweed waste, and in particular relates to a method for promoting efficient decomposing of Enteromorpha powder by enzymatically decomposing kelp residue and an application of the product. Background technique [0002] In recent years, with the diversification of the development direction of organic fertilizers in my country, the number of seaweed fertilizer production enterprises is increasing day by day, and the market share of seaweed fertilizer is increasing day by day. What follows is how to develop and utilize the leftovers produced by seaweed fertilizer production enterprises, such as Utilization of enzymatically hydrolyzed kelp slag; In addition, from 2007 to 2009, my country's coastal waters encountered successive disasters of Enteromorpha green algae, which is rare in history. How to deal with and utilize Enteromorpha has also become an important iss...
