Process for preparing stress-resistance seaweed fertilizer

Abstract

The invention discloses a process for preparing stress-resistance seaweed fertilizer comprising the steps of, (1) airing seaweed, removing impurity substance, (2) charging fresh water, (3) agitating and steeping, decompression concentration, separating high temperature salt by centrifugal separation, (4) disintegrating concentration liquid with dried solid evolution, (5) charging 95% of ethanol into fresh seaweed, (6) squashing the algae, agitating, centrifuging and storing the liquid, (7) removing salt from the solution through compression, (8) cooling down, charging saturated diamino ammonium chromic thiocyanate solution, (9) collecting deposition, (10) mixing the compression liquid, dried solid substance and precipitate homogeneously, (11) spray drying.

Description

technical field

[0001] The invention relates to seaweed chemistry, in particular to a preparation method of stress-resistant seaweed fertilizer. Background technique

[0002] my country is a large agricultural country, and the use of chemical fertilizers ranks first in the world. The use of a large amount of chemical fertilizers has caused the deterioration of soil compaction (especially in the Hexi Corridor of my country) and the reduction of crop quality. In addition, my country is relatively short of water resources, and 380 million mu of farmland is dry and semi-arid. The common chemical fertilizers currently used in my country and the general liquid fertilizers abroad are not very specific to the above-mentioned agricultural characteristics of our country. Stress-resistant seaweed fertilizer is to use my country's existing rich seaweed resources to develop a kind of fertilizer that can increase crop yields, reduce soil compaction, and improve fertilizer production acco...
