Zinc is one of the trace elements necessary for the growth and development of vegetables. Many vegetables use zinc fertilizer to increase the yield. Cauliflower, beet, spinach, Chinese cabbage, tomato, eggplant, radish, onion and legume vegetables are all zinc-like vegetables. The application of zinc fertilizer can increase the yield and improve the quality. According to the test, the application of zinc fertilizer on tomato, cucumber and radish can increase production by 13%-15%. The method of applying zinc fertilizer to vegetables is as follows:
First, the application of base fertilizer
The main variety of zinc fertilizer is zinc sulfate. When used as base fertilizer, it is generally used 1-2kg per acre, mixed with organic fertilizer or physiological acid fertilizer evenly. Note that zinc fertilizer should not be mixed with phosphate fertilizer, because phosphorus and zinc are mutually antagonistic, and mixed application will reduce their respective fertilizer effects. Zinc fertilizer has a post-effect effect, and it does not need to be applied every year. It can be applied once every 2-3 years.
Second, for seed fertilizer application
Zinc fertilizer is used as seed dressing for seed dressing, soaking and rooting. The seed dressing is usually 2-3g of zinc sulfate per kg of seed, first dissolved with a small amount of water, then sprayed on the seed, while spraying and mixing, water consumption It is advisable to mix the seeds well and dry them to be sown. Soaking seeds generally use a concentration of 0.02%-0.05% zinc sulphate solution, soak the selected seeds into a good solution of zinc sulphate for 8-10 hours, remove and dry to sown. Alfalfa root is a cost-effective and effective method of increasing yield. When transplanting vegetables, the roots are planted in a 1% zinc oxide suspension.
Third, for topdressing application
Topdressing can apply zinc fertilizer directly to the soil, or dilute the zinc fertilizer for foliar application. Soil topdressing generally uses 1-2kg of zinc sulfate per acre, preferably concentrated application, and its application or hole is applied near the root system to facilitate root absorption and improve the utilization rate of zinc fertilizer. Spraying is a commonly used method of topdressing, which can be applied to all classes of vegetable growth and development. Especially when the vegetables are exposed to zinc deficiency symptoms, the zinc deficiency can be rapidly transformed. The spray is generally used with 0.05%-0.1% zinc sulfate solution, and the 0.1% dilution solution is sprayed three times during the whole growth period. the best. Tomatoes should be sprayed once after fruit setting and early fruit picking; cucumbers should be sprayed once in the seedling stage, after the root melon is sitting and in the early harvesting stage; the Chinese cabbage should be sprayed once in the seedling stage, the rosette stage and the early stage of the ball. It is best to spray after 4 pm, especially in the evening, and spray the whole plant evenly.
