Do not overdose. The reason why zinc fertilizer is micro-fertilizer is that the crop needs less of it. If the application amount is too large, it will have a toxic effect on the crop (some vegetable farmers apply 3 kg of zinc sulfate in the bottom fertilizer, and the leaf surface is frequently supplemented with zinc fertilizer. Zinc sulfate reached 250 grams). It leads to stagnation of crop growth and small and thin leaves, affecting normal photosynthesis.
Do not apply continuously in the base fertilizer. Zinc fertilizer is generally effective as a base fertilizer for a long period of time, and it can be applied for one to two years. In addition to severe zinc-deficient soils, it is recommended that zinc fertilizer be applied once a year. In actual production, vegetable farmers will apply zinc fertilizer at the bottom of each stubble vegetable planting, resulting in the application of zinc fertilizer twice in a year, which makes the residual zinc fertilizer in the soil too large, and inhibits the absorption of other elements by the soil.
Do not mix with alkaline fertilizers and alkaline pesticides. Zinc mixed with alkaline fertilizers will react to reduce fertilizer efficiency. Similarly, when zinc is mixed with alkaline pesticides, the effectiveness of zinc and pesticide efficacy are also reduced. Moreover, if zinc fertilizer is mixed with phosphate fertilizer, zinc phosphate precipitation will be easily formed. Not only reduces the effectiveness of zinc, but also reduces the effectiveness of phosphorus. So the two cannot be used at the same time.
When zinc fertilizer is used as the base fertilizer, whether it is one-stubble vegetable or multi-stubble cultivation, it can be applied once every year. According to the different levels of zinc deficiency in the soil, 0.5 to 2 kg of zinc sulfate is applied per mu when used as a base fertilizer. For top dressing, use 0.75 ~ 1 kg of zinc sulfate per mu mixed with appropriate amount of fine soil; for foliar spraying, use 90 ~ 180 g of zinc sulfate per mu with 60 kg of water on sunny days. When using it, it is best to use it alone to avoid reacting with other chemical fertilizers and affecting the absorption of zinc by crops.
