Technical field
The invention belongs to composite fertilizer's production technical field, is a kind of working method of Synergistic composite fertilizer specifically.
Background technology
The soil application situation of China biases toward the chemical fertilizer input at present, but the utilization ratio of chemical fertilizer does not but improve, owing to excessively blindly add the usage quantity of large chemical fertilizer, chemical fertilizer utilization ratio is had a declining tendency.China accounts for the arable land in the world 10% and has but consumed the chemical fertilizer in the world 30%, and the chemical fertilizer input amount of unit cultivated area is 2.8 times of the average consumption in the world.Utilization rate of fertilizer is low, and soil-borne disease insect pest aggravation causes severe environmental pollution and agricultural product quality to descend, and threatens the Sustainable development of national food safety and agricultural to a great extent.
Marine alga is handled through special biochemical process; Extract its elite material; Greatly kept the natural radioactivity component; Be rich in kind of mineral element and abundant VITAMINs surplus potassium, calcium, magnesium, iron, zinc, the iodine etc. 40 in the marine alga, contain peculiar Sargassum polysaccharides in the marine alga, protein, amino acid, highly unsaturated fatty acids and multiple natural phant growth regulator especially, have very high biological activity.Sodium-alginate is nontoxic odorless, white or pale yellow powder, and its water-soluble fluid power and divalent metal react the formation gel rapidly.Sodium-alginate is soluble in water, has thickening, suspension, emulsification, stablizes, forms gel and film forming characteristic.
How marine alga is organically combined with composite fertilizer, improve the absorption rate of composite fertilizer, solve existing fertilizer and absorb too low problem, this is the problem that the present invention faces.
Summary of the invention
The purpose of this invention is to provide a kind of method of utilizing marine alga to prepare Synergistic composite fertilizer.The break the normal procedure structure of composite fertilizer of this Synergistic composite fertilizer is the synergy raw material with the Lalgine, is processed into through science.Lalgine can not only promote plant to nutrient absorbing as synergistic agent, can also play the effect of slow controlled release, coating to nutrient, for crop provides safer growing environment, promotes crop stable and high yields, high-quality.
Technical scheme of the present invention is: a kind of Synergistic composite fertilizer is characterized in that: comprise synergistic agent Lalgine and inorganic nutrients, the content of said Lalgine is 0.3% ~ 20%, and the content of inorganic nutrients is (with N, P
