Matters needing attention in applying zinc fertilizer to vegetables

Zinc is one of the necessary trace elements in the growth and development of vegetables. many vegetables will have obvious yield-increasing effect after using zinc fertilizer, such as tomato, Chinese cabbage, eggplant and legume vegetables. But although vegetables need to supplement zinc, but it does not mean that the more zinc, the better, and then the application of zinc fertilizer must pay attention to a few points, let's take a look.

1. Do not overdose

The reason why zinc fertilizer is micro-fertilizer is that crops have less demand for it, and if excessive application will cause toxic effect, many vegetable farmers blindly abuse zinc fertilizer and apply enough zinc fertilizer in the base fertilizer, but apply zinc fertilizer frequently in the later stage. This will only cause slow growth or even stagnation of vegetables, small and thin leaves, affecting normal photosynthesis, low yield and quality, and some even lose commodity value, resulting in great loss of talent.

2. do not apply it continuously in the base fertilizer.

Zinc fertilizer as a base fertilizer generally has a very long period of validity and can last for 1-2 years at a time. Except for the plots with serious zinc deficiency, it is generally recommended to apply it once a year. However, in actual production, many vegetable farmers often apply it once during soil preparation and again during planting, which leads to the continuous application of zinc fertilizer twice a year, which will cause excessive zinc fertilizer in the soil and inhibit the absorption of other elements by roots. in the growing period, it will cause the deficiency of other elements, affecting the yield and quality.

3. Do not mix it with alkaline fat medicine

When zinc is mixed with alkaline fertilizer, its fertilizer efficiency will be reduced because of chemical reaction. Similarly, when mixed with alkaline medicine, the validity of zinc fertilizer will decrease with the properties of pesticides. For example, when zinc fertilizer and phosphate fertilizer are mixed, it is very easy to form zinc phosphate precipitation, which will not only reduce the effectiveness of zinc, but also reduce the fertilizer efficiency of phosphate fertilizer, so we must pay attention to the two can not be used at the same time.

4. Pay attention to the amount of application

When zinc fertilizer is used as base fertilizer, 0.5-2 kg zinc sulfate per mu should be applied according to the degree of zinc deficiency in the soil, not too much; 0.75-1 kg per mu should be applied as topdressing, and it should be mixed with fine soil before spreading. If it is foliar spraying, then after diluting 90-180 grams of zinc sulfate with water per mu, choose to spray on a sunny day, pay attention to the concentration, and at the same time, it is best to use it alone, so as to avoid reacting with other agents or fertilizers, thus reducing the absorption and utilization of zinc by crops.
