Description
Technical field
The invention belongs to composite fertilizer's production technical field, is a kind of production method of Synergistic composite fertilizer specifically.
Background technology
The soil application situation of present China biases toward chemical fertilizer and drops into, but the utilization ratio of chemical fertilizer does not but improve, because the excessive usage quantity that blindly adds large chemical fertilizer makes chemical fertilizer utilization ratio have a declining tendency on the contrary.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 to a great extent the Sustainable development of national food safety and agricultural.
Marine alga is processed through special biochemical process, extract its elite material, greatly kept the natural radioactivity component, be rich in potassium, calcium, magnesium, iron, zinc, iodine etc. more than 40 in the marine alga and plant mineral element and abundant VITAMIN, contain especially peculiar Sargassum polysaccharides in the marine alga, protein, amino acid, highly unsaturated fatty acids and multiple natural phant growth regulator, have very high biological activity.Sodium alginate is nontoxic odorless, white or pale yellow powder, and its aqueous solution can react rapidly the formation gel with divalent metal.Sodium alginate is soluble in water, has thickening, suspension, emulsification, stablizes, forms gel and film forming characteristic.
How marine alga organically is combined with composite fertilizer, improves 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 take Lalgine as the synergy raw material, is processed into through science.Lalgine can not only promote plant to the absorption of nutrient as synergistic agent, can also play to nutrient the effect of slow controlled release, coating, 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 described Lalgine is 0.3% ~ 20%, and the content of inorganic nutrients is (with N, P
