Abstract

Belonging to the technical field of fertilizers, the invention relates to a salt-alkali resistant, anti-continuous cropping and disease resistant macroelement water-soluble fertilizer (medium elementtype) and a preparation method. The water-soluble fertilizer is prepared from the following raw materials and formula: 10-20% of urea, 5-10% of crystal monoammonium phosphate, 20-30% of potassium dihydrogen phosphate, 30-40% of potassium sulfate, 5-10% of potassium fulvate, 5-10% of sodium humate, 2-5% of calcium ammonium nitrate, 2-5% of magnesium sulfate, 2-3% of amino acid powder, 1-1.5% of chitin, 0.3%-0.5% of compound sodium nitrophenolate, 0.2-0.3% of diethyl aminoethyl hexanoate, 0.2-0.3% of agricultural streptomycin, and 0.1-0.2% of bacillus subtilis. The water-soluble fertilizer provided by the invention is a good innovation, realizes the new breakthrough of combination of nourishing, disease resistant and yield increasing pesticides and fertilizers, and is incomparable by other water-soluble fertilizer patents. The macroelement water-soluble fertilizer especially has unique effects in salt and alkali resistance, continuous cropping resistance and disease resistance, completely solves the nutrient deficiency symptom and physiological diseases of crops, increases yield, improves quality, is green and environment-friendly, and is conducive to the development of ecological agriculture. The macroelement water-soluble fertilizer provided by the invention fills the domestic blank, and the technology takes the leading position at home and abroad.

Description

technical field [0001] The invention belongs to the technical field of agricultural chemical fertilizers, and relates to a water-soluble fertilizer with a large amount of elements, in particular to a water-soluble fertilizer with a large amount of elements which is resistant to salinity, heavy cropping and disease (middle element type) and a preparation method. Background technique [0002] Water-soluble fertilizer (Water Soluble Fertilizer, WSF for short) is a kind of multi-element compound fertilizer that can be completely dissolved in water. It can be quickly dissolved in water and easily absorbed by crops. It is used in sprinkler irrigation, drip irrigation and other facility agriculture to realize the integration of water and fertilizer, and achieve the effects of saving water, fertilizer, labor and increasing production. It is one of the important directions of fertilizer development in the future. [0003] There were earlier reports on the patented technology of wate...
