Iodine alginate aqua medical fertilizer and preparation method thereof

Abstract

The invention discloses an alga iodic acid aqueous medical fertilizer and a preparation method thereof. Each liter of the aqueous medical fertilizer comprises the following raw materials in mass percentage: 20 to 30 percent of alginic acid, 10 to 30 percent of mannite, 8 to 72 percent of potassium iodide, 1.6 to 15 percent of potassium iodate, 2 to 18 percent of iodine, 100 to 150 percent of monopotassium phosphate, 44 to 71 percent of anhydrous borax and the balance being water. The preparation method comprises the following steps: (1) the raw materials are taken out for standby according to mass ratio; (2) the anhydrous borax is dissolved in water to obtain a borax liquid; (3) the alginic acid is placed in the borax liquid, is evenly mixed, is added with the mannite and the monopotassium phosphate, and is stirred and dissolved to obtain a standby liquid A; (4) the potassium iodide, the potassium iodate and the iodine are placed in the water and are dissolved to obtain a standby liquid B; and (5) the standby liquid A and the standby liquid B are evenly mixed and stirred; after stirring and precipitation, a supernatant liquid is obtained and is the alga iodic acid aqueous medical fertilizer. The alga iodic acid aqueous medical fertilizer is suitable for various crops, is safe and reliable, has no pollution, no residue and no harm, is not influenced by geographical environment and climate, can promote growth of the crop, improve adverse resistance and the like.

Description

technical field [0001] The invention relates to a foliar fertilizer and a pesticide, and is an iodine alginate aqueous medicinal fertilizer and a preparation method thereof. Background technique [0002] Many soils in our country are iodine-deficient soils. Due to the extreme lack of iodine, it is easy to make the pests and diseases of crops more and more serious. In addition, due to the extensive use of nitrogen fertilizers, fungicides, pesticides and hormone drugs, crops such as vegetables and fruits contain a large amount of toxic residues, which brings great harm to people's food safety. Therefore, this field has been researching pollution-free, non-residue, and pollution-free foliage fertilizers and pesticides in recent years, in order to solve the deficiencies of existing foliage fertilizers and pesticides. After searching, although iodine is used as a component in pesticides, because surface detergents, nitrogen fertilizers, hormones and other substances are also use...

Problems solved by technology

After searching, although iodine is used as a component in pesticides, because surface detergents, nitrogen fertilizers, hormones and other substances are also used in its components, chemical reactions occur and complex compounds are produced, which are prone to phytotoxicity to crops , and cause leaves to wither on watermelon, cantaloupe seedlings and other melons and fruits, etc., so far cannot be widely used
