Uses of Zinc Sulphate Monohydrate

1. Ecological uses

Zinc can promote photosynthesis of crops. Zinc is the specific activating ion of carbonic anhydrase in plant chloroplasts, which can catalyze the hydration of carbon dioxide in photosynthesis. At the same time, zinc is also an activator of aldolase, which is one of the key enzymes in the photosynthesis process. Therefore, the use of zinc sulphate monohydrate can enhance the chemical synthesis of plants. At the same time, zinc is a necessary component of protein synthesis and ribose in animal and plant cells, proving that zinc is an essential element for the growth of animals and plants.

2. Agricultural uses

Zinc sulphate monohydrate is widely used in fertilizers and compound fertilizers in agriculture as a zinc supplement and an insecticide to prevent fruit tree diseases and pests. The use of zinc sulphate in agriculture is divided into base fertilizer, foliar spraying, seed soaking, and seed mixing. When plants are zinc deficient, their growth is stunted, the plants are short, the internode growth is severely hindered, and the interveinal leaves lose green or whiten. New leaves have gray-green or yellow-white spots. Symptoms of zinc deficiency in vegetables include shortened internodes, dwarfed plant growth, chlorosis of leaves, inability of some leaves to expand normally, poor root growth, and few or deformed fruits.

Before seed mixing, dissolve a certain amount of micro-fertilizer in water to make a dilute solution (generally between 0.02% and 0.1%), then put the micro-fertilizer solution into a sprayer or spray pot, spray it on the seeds with a sprayer, and stir while spraying to make each seed evenly covered with fertilizer liquid. The solution should not be too much to avoid wrinkling of the seed coat and causing rotten seeds. After mixing, spread the seeds out and dry them before sowing.

Second, when soaking seeds, first dissolve zinc sulphate monohydrate to make a solution with an appropriate concentration of 0.02% to 0.05%, then soak the seeds for 6 to 8 hours, remove the seeds and dry them slightly before sowing. If the concentration of zinc sulfate solution is greater than 0.1%, it will affect seed germination. The method of seed soaking and fertilization requires good soil moisture in the sowing area, generally above yellow moisture; if the soil is dry and reaches the gray moisture level, the soil around the seeds after sowing will consume a lot of water and affect germination.

Third, seed coating: mix zinc sulphate trace element fertilizer and added regulator into a solution of a certain viscosity, roll and wrap it in the coating machine for a certain period of time and dry it before sowing. This method is being promoted.

3. Industrial use

Zinc sulphate monohydrate has been widely used in chemical industry, national defense, mineral processing, pharmaceuticals, rubber, electronics, printing and dyeing agents, gelatin clarifiers and protective agents, electroplating, prevention of fruit tree diseases and pests and circulating cooling water treatment, viscose fibers and nylon fibers. It is the raw material for making zinc salts and zinc barium white. It is used for cable zinc and electrolytic pure zinc in the electrolytic industry. It is also used to prevent and control fruit tree nursery diseases, wood and leather preservatives and artificial fiber industry. Mordant in the printing and dyeing industry; preservative for wood and leather; water treatment agent for circulating cooling; gelatin clarifier and preservative.
