Abstract

The invention discloses nitrification-inhibitor-containing special potato drop irrigation fertilizer and a preparation method thereof. The nitrification-inhibitor-containing special potato drop irrigation fertilizer comprises, by weight, 50-70 parts of urea, 13-20 parts of ammonium nitrate, 15-22 parts of monopotassium phosphate, 10-17 parts of potassium nitrate, 3-10 parts of zinc sulfate, 2-9 parts of boracic acid, 2-7 parts of manganese sulfate, 3-8 parts of ammonium cuprate, 2-8 parts of ferrous sulfate, 12-21 parts of nitrification inhibitors, 1-5 parts of plant growth regulators, 2-7 parts of fulvic acid, 2-6 parts of amino acid and 15-20 parts of sodium thiosulfate. The preparation method includes subjecting the raw materials to ultrasonic dispersion, and evenly stirring and mixingthe raw materials. The nitrification-inhibitor-containing special potato drop irrigation fertilizer has the advantages that negative effect is avoided after the fertilizer is applied to potatoes, water solubility is high, soil hardening is avoided, the fertilizer is convenient to use, the problem of heavy metal pollution of soil is solved effectively, and growth trend of the potatoes is improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and relates to a special drip irrigation fertilizer for potatoes containing nitrification inhibitors and a preparation method thereof. Background technique [0002] Drip irrigation fertilizer is a kind of fertilizer that is applied along with irrigation. Because drip irrigation fertilizer has the characteristics of easy use, easy absorption by crops, and outstanding fertilizer effect, it has been welcomed by farmers. [0003] Potato is a perennial herbaceous plant belonging to the family Solanaceae, and its tubers are edible. It is the fourth most important food crop in the world, second only to wheat, rice and corn. Potatoes are also called ground eggs, potatoes, yams, etc. Potato tubers contain a lot of starch. Generally, early-maturing potatoes contain 11%-14% starch, mid-late-maturing potatoes contain 14%-20% starch, and high-starch tubers can reach more than 25%. Tubers also contain gl...
