Dedicated watermelon set water-soluble fertilizer and preparation method thereof

Abstract

The invention discloses a dedicated watermelon set water-soluble fertilizer which is prepared from a vine growing fertilizer and a fruit expanding fertilizer, wherein the vine growing fertilizer is prepared from the following raw materials in parts by weight: 400 to 520 parts of potassium nitrate, 250 to 350 parts of urea, 20 to 120 parts of monopotassium phosphate, 5 to 200 parts of monoammoniumphosphate, 27 parts of boric acid, 10 to 100 parts of magnesium sulfate, 5 parts of chelated zinc, 2 parts of chelated copper and 2 parts of chelated iron; the fruit expanding fertilizer is prepared from the following raw materials in parts by weight: 650 to 670 parts of potassium nitrate, 100 to 130 parts of urea, 10 to 100 parts of ammonium phosphorus nitrate, 90 to 110 parts of monoammonium phosphate, 10 parts of boric acid, 10 to 100 parts of magnesium sulfate, 5 parts of chelated zinc, 2 parts of chelated copper and 4 parts of chelated iron. The dedicated watermelon set water-soluble fertilizer and a preparation method of the dedicated watermelon set water-soluble fertilizer disclosed by the invention are matched with the watermelon nutrition absorption characteristics, so that watermelon nutrition requirements can be met, watermelon yield is improved, and watermelon quality is improved; the fertilizer use amount is effectively reduced, application of a water-fertilizer integration technology is promoted, and the purposes of saving water and saving fertilizers are achieved.
