Zinc sulfate fertilizer is a trace element fertilizer, mainly used to supplement the zinc required by plants. Zinc is one of the essential trace elements for plant growth and plays an important role in plant growth and development. The following is the main role and use of zinc sulfate fertilizer:

‌ Main role ‌ :

Promotes photosynthesis: Zinc is a component of chlorophyll and has an important effect on the photosynthesis of plants. The application of zinc fertilizer can improve the photosynthetic efficiency of plants, increase the synthesis of organic matter, and thus improve the yield and quality of plants.
Improve stress resistance: Zinc can also enhance the stress resistance of plants, making plants more resistant to adverse environmental conditions, such as drought and low temperatures.
Improve fruit quality: Zinc fertilizer can improve the appearance and taste of the fruit, making the fruit more full and colorful.
‌ Usage ‌ :

Base fertilizer: When ploughing, evenly turn zinc sulfate into the soil, the amount per mu is 0.5 to 2 kg. The mobility of zinc in the soil is poor, and the effect of surface application is not good, so it should be evenly turned into the soil when tilling. Base fertilizer need not be applied every year, can be applied every other year.
Dip root: Dip root with 0.1% to 0.2% concentration of zinc oxide solution, suitable for rice, vegetables and other crops.
Soak seeds: Soak the seeds in a solution of 0.02% to 0.05% zinc sulfate for 6 to 12 hours, then let them dry for sowing. This method is suitable for peanuts, soybeans and other seeds.
Seed mixing: Mix zinc fertilizer with seeds, mixing 2 to 6 grams of zinc fertilizer per kilogram of seeds. This method is suitable for all kinds of crops.
Foliar spraying: in the critical growth period of rice, corn and other crops, such as seedling stage, jointing stage, filling stage, etc., foliar spraying is carried out. 60 to 70 kg of 0.2% zinc sulfate solution per mu is sprayed once every 7 to 10 days, a total of 1 to 2 times. Spray time should be chosen in the morning or evening on sunny days, avoid spraying in rainy days or high temperature periods.
Applying zinc sulfate fertilizer through the above method can effectively supplement the zinc required by plants, promote the healthy growth of plants, and improve the yield and quality
