The content of available zinc in cultivated soil is the main basis for applying zinc fertilizer. When the content of available zinc per kilogram of soil is less than 0.5 mg, zinc fertilizer should be applied reasonably. In general, alkaline soils, acidic soils with excessive application of quicklime, soils with poor organic matter, soils with excessive application of chemical nitrogen and phosphorus fertilizers, and soils that are often flooded have low available zinc content and are prone to zinc deficiency. Reasonable application of zinc fertilizer has obvious effect of increasing yield. In addition, the sensitivity of crops to zinc response is also an important basis for applying zinc fertilizer. The crops sensitive to zinc response mainly include rice, corn, wheat, peanut, soybean, sugar beet, cotton, apple, peach, pear, apricot, cherry, bayberry , citrus, grape, tomato, eggplant, cucumber, kidney bean, potato, onion, etc. Under normal circumstances, the normal zinc content per kilogram of crops is 20-100 mg. When the zinc content is less than 20 mg, these crops will Showing symptoms of zinc deficiency, therefore, for crops sensitive to zinc response, if zinc fertilizer is applied reasonably, the yield increase effect will be obvious.
