Zinc Sulfate Heptahydrate Granules

Chinese Name:Zinc Sulfate Heptahydrate
Chinese Synonyms:Goslarite, Zinc Vitriol, Zinc Sulfate, Zinc Sulfate Heptahydrate
English Name:zinc sulfate heptahydrate; zinc vitriol; white vitriol
Molecular Formula:ZnSO₄·7H₂O
Molecular Weight:287.54
Specific Gravity:1.957
CAS No.: 7446-20-0
National Standard: HG/T 2326-2005
Physical Properties:Relative density: 1.957, melting point: 1000℃. Freely soluble in water (96.5g/100ml at 20℃; 663.6g/100ml at 100℃), slightly soluble in ethanol and glycerol.

Crops sensitive to zinc deficiency:corn, rice, sugar beet, soybean, kidney bean, citrus, pear, peach, tomato, etc., among which corn and rice are the most sensitive. The application of zinc fertilizer has an obvious effect on preventing and controlling "white stripe seedling" caused by zinc deficiency in corn and little leaf disease in fruit trees.

Application MethodFoliar spray:Dilute with water by 1000–1500 times, spray evenly on the leaf surface for 2–3 consecutive times at an interval of 10–15 days.
Base fertilizer or topdressing:Apply 500–1000 grams per mu mixed evenly with fine soil or farmyard manure.
Seed dressing:Use 2–3 grams of this product per kilogram of seeds, dissolve in a small amount of water and mix evenly with seeds.
Seed soaking:Soak seeds in a 0.02–0.05% solution (diluted 2000–5000 times) for 8–12 hours, air-dry before sowing.
