Embodiment 1

[0039] Embodiment 1: the preparation method of enteromorpha seaweed essence

[0040] Add 2000kg of water to 100kg of Enteromorpha powder that has been desanded, dried and crushed, adjust the pH to 1-2 with hydrochloric acid, heat and stir for extraction at 50°C for 4 hours, filter, and concentrate the supernatant in vacuum to a specific gravity of 1.25 g / ml, obtained seaweed powder by spray drying.

Embodiment 2

[0041] Implementation 2: Preparation method of Enteromorpha seaweed foliar fertilizer

[0042] Add 1200kg of water to 100kg of Enteromorpha powder that has been desanded, dried and crushed, adjust the pH to 9.5 with potassium hydroxide, stir and extract at 85°C for 5 hours, filter, and concentrate the supernatant in vacuum to a specific gravity of 1.2g / ml. Add the urea of ​​Enteromorpha concentrate weight 12% in Enteromorpha concentrate, the potassium dihydrogen phosphate of Enteromorpha concentrate weight 5%, the potassium sulfate of Enteromorpha concentrate weight 6%, the trace amount of Enteromorpha concentrate weight 5% Elements (selected from copper, iron, manganese, zinc, boron, and molybdenum) are fully stirred and dissolved to obtain Enteromorpha seaweed foliage fertilizer.

Embodiment 3

[0043] Implementation 3: A preparation method for Enteromorpha fertilization

[0044] Add 1500kg of water to 100kg of enteromorpha powder that has been desanded, dried and crushed, adjust the pH to about 1-2 with sulfuric acid, heat and stir for extraction at 60°C for 3 hours, filter, and concentrate the supernatant in vacuum until the specific gravity is 1.16g / ml, in the enteromorpha concentrate, add potassium humate of enteromorpha concentrate weight 20%, urea of ​​enteromorpha concentrate weight 15%, monoammonium phosphate of enteromorpha concentrate weight 10%, enteromorpha concentrate Potassium sulfate of 10% by weight is fully stirred evenly to obtain Enteromorpha seaweed and fertilized.

Abstract

The invention provides effective technology for extracting active ingredients of Entermorpha and a method for preparing an Entermorpha alga fertilizer. The method is characterized by comprising: taking the Entermorpha as a raw material, effectively extracting the active ingredients of the Entermorpha through technical processes such as pretreatment of raw materials, leaching, neutralization, concentration and combination, taking an extracting solution as a base fluid, combining the extracting solution with at least one composition of humic acid, urea, potassium dihydrogen phosphate, potassiumsulfate, monoammonium phosphate and microelement, and preparing the high-activity Entermorpha alga fertilizer. The Entermorpha alga fertilizer is rich in active substances of algae, not only can strengthen photosynthesis of crops, increase the yield of the crops and improve the product quality but also can strengthen the cold resistance, the drought resistance, the stress resistance and the disease resistance of the crops, promote earliness of the crops and increase the fertile flower percentage and the fertile fruit percentage, has lower production cost, good solubility and safe use, is friendly and harmless to human beings, domestic animals and the natural environment, and is a novel environment-friendly fertilizer suitable for modern agriculture.

Description

technical field [0001] The invention relates to the fields of chemical extraction technology and fertilizer production technology, in particular to an extraction technology of active components of Enteromorpha and a preparation method of Enteromorpha seaweed fertilizer. Background technique [0002] From June to July 2008, for the smooth holding of the Qingdao Olympic Sailing Competition, the military and civilians in Qingdao worked together to salvage tens of thousands of tons of enteromorpha, and a large amount of enteromorpha was transported to the garbage factory, causing huge damage to the environment of Qingdao. pressure, but also caused a great waste of Enteromorpha resources. Entermorpha (Entermorpha) is a large-scale economical green algae, commonly known as moss strips and seaweed, which belongs to the Ulvaceae plant of the Chlorophyta Ulceraceae. Its algal body is green, tubular, membranous, clustered, with obvious main branches and slender branches, up to 1 mete...
