Zinc chloride can be used as base fertilizer, topdressing, foliar spraying and seed soaking.

Zinc chloride, also known as zinc chloride powder, has an effective zinc content of 40% ~ 48%. White hexagonal crystal is granular crystal or powder, which is easily soluble in water, methanol, alcohol, glycerol and acetone, pyridine, aniline and other nitrogen-containing solvents, but insoluble in liquid ammonia. The symptoms of crop zinc deficiency mainly occurred in the early stage of growth, mainly manifested as internode shortening, short plants, smaller and deformed leaves, and chlorotic stripes or white lines, forming leaf clusters. When tomato is short of zinc, the plant grows thin, the leaves are twisted, and the yellow spots appear on the surface. Then the yellow spots gradually expand, the whole plant turns yellow, the branches and leaves droop and scorch, and the results are small. When cucumber is zinc deficient, the plant grows poorly, the edges of old leaves turn yellow and zoom, and gradually expand inward in an irregular manner. Small yellow spots appear on the leaf surface. The results are short and thick. The peel forms wide green and narrow white stripes, and the green of the stripes is shallow. When eggplant is short of zinc, the plant grows short, the top leaves are thin and long, both sides of the leaves roll up, and the lower leaves lose a lot of green, or even completely green. Zinc fertilizer is a material with marked amount of zinc to provide plant nutrients as its main effect. The commonly used zinc fertilizers are zinc plus selenium, zinc sulfate heptahydrate and zinc sulfate monohydrate. Basic zinc sulfate, zinc chloride, zinc oxide, zinc sulfide, zinc phosphate, basic zinc carbonate, zinc vitreous, lignin zinc carbonate, zinc naphthenate emulsion and chelated zinc can be used as zinc fertilizer. The latter three are organic zinc fertilizers, which are easily soluble in water. Zinc fertilizer can be used as basal application, topdressing, seed soaking, seed dressing and spraying. Generally speaking, it can be used as foliar fertilizer spraying effect. Zinc fertilizer is applied to zinc sensitive crops, such as corn, rice, peanut, soybean, sugar beet, kidney bean, fruit tree and tomato. Application on zinc deficient soil: it is better to apply Zinc Fertilizer on zinc deficient soil, and there is no need to apply Zinc Fertilizer on non zinc deficient soil.

Fertilize corn and other crops with zinc chloride products. Through the use of these fertilizers, the zinc content in crops is greatly increased and transmitted to consumers when eating crops. Zinc chloride is also used in the production of astringents for the treatment of corn. When zinc chloride is added to irrigation water, it helps to reduce the salt content in the water. This reduces the negative impact of salt on crop soil drainage and helps to eliminate the costly consequences of drainage problems for farmers.
