Problems solved by technology

In addition, in recent years, algae such as Enteromorpha have flooded coastal areas such as Yantai, Weihai, and Qingdao, seriously polluting the environment and even affecting coastal landscapes.
[0008] At present, most manufacturers at home and abroad mainly use chemical hydrolysis to produce seaweed fertilizer, that is, use strong acid and strong alkali to treat seaweed under severe conditions of high temperature and high pressure. lots of active ingredients

Abstract

The invention discloses an algae organic fertilizer. A preparing process of the algae organic fertilizer includes steps of (1) removing sand of algae, drying the same in the sun or baking the same by the temperature of 50 DEG C to 70 DEG C and obtaining dried algae; (2) smashing the dried algae to be algae powder, mixing the algae powder with water and breaking wall by ultrasonic waves to obtain leach liquor; and (3) filtering, centrifuging, decolorizing, concentrating and drying the leach liquor, and finally the algae organic fertilizer is formed. Further, in order to enhance nutrition, nutrient components, such as urea, monopotassium phosphate and microelements and the like can be added according to needs, so that the required algae organic fertilizer can be obtained. The algae organic fertilizer extracted by ultrasonic waves has the advantages that extraction time is short, yield is high, degradation and denaturation at the high temperature for a long time and damages to effective constituents by high temperature and high pressure are avoided, and heating is omitted and the like as compared with that extracted by conventional extraction method. Algae are used as raw materials for producing the algae fertilizer, so that the problem of pollution to the environment is solved, waste is changed into treasure, production cost is saved, and the algae organic fertilizer has great economic value and profound and lasting environmental significance.

Description

technical field [0001] The invention relates to a seaweed organic fertilizer and a preparation process thereof. Background technique [0002] At present, the long-term application of chemical fertilizers has damaged the ecological environment of the farmland, the physical and chemical properties of the soil, and the effective bacterial flora of the soil to varying degrees, which has a great impact on the quality of the crops. In particular, excessive application of simple chemical fertilizers such as nitrogen fertilizers will intensify soil compaction and reduce soil fertility, making it difficult for the quality and nutrition of crop products to meet people's needs, let alone meet the requirements of green food, and cause serious environmental pollution. [0003] Traditional chemical fertilizers have single fertilizer effects and serious pollution, and long-term use will cause soil damage. According to the survey of relevant experts, the application amount of chemical fert...
