Zinc fertilizer refers to zinc sulfate, which can be applied either as a base fertilizer or as a top dressing. When applied as a base fertilizer, use 2 kg of zinc sulfate per acre, mix 15 kg of fine soil, spread it evenly before the preparation of the ground, and then plow it, or apply it properly.

Stainless steel round steel belongs to a class of long wood, also belongs to a class of bar, the so-called stainless steel round steel refers to the cross section of uniform circular long wood, generally about four meters long. It can be divided into light circles and black rods. The so-called light circle, refers to the smooth surface, after the quasi-rolling treatment; And the so-called black rod, refers to the surface of the black thick, hot rolled directly.
Stainless steel round steel can be divided into hot rolling, forging and cold drawing according to the production process. Hot rolled stainless steel round steel is 5.5-250 mm in size. Among them :5.5-25 mm small stainless steel round steel mostly to straight strips in bundles supply, commonly used for reinforcing bars, bolts and various mechanical parts; Stainless steel round steel greater than 25 mm, mainly used in the manufacture of machine parts or seamless steel pipe billets.
Stainless steel round steel has broad application prospects, and is widely used in hardware kitchenware, shipbuilding, petrochemical, machinery, medicine, food, power, energy, aerospace, building decoration. Seawater equipment, chemical, dye, paper, oxalic acid, fertilizer and other production equipment; Photography, food industry, coastal facilities, ropes, CD rods, bolts, nuts.
High zinc yield in vegetables
Zinc is one of the essential trace elements in crops. Many vegetables have obvious yield-increasing effects after applying zinc fertilizer. After applying zinc fertilizer, such as cabbage, celery, cucumber, pepper, spinach, etc., it can generally increase yield by more than 12%.
