Technical points for applying watermelon micro-fertilizer
Zinc fertilizer is commonly in the form of zinc sulfate and can be applied as a base fertilizer, seed treatment, or foliar top dressing. For base application, it is recommended to use 1 to 1.5 kg of zinc sulfate per 667 square meters (1 mu). However, it should not be mixed with phosphate fertilizers. For seed treatment, a 0.1% solution can be used for soaking, or 1 gram of zinc sulfate per kilogram of seed for coating. Foliar application typically uses a 0.01–0.05% zinc sulfate solution.
Boron fertilizers include materials such as borax, boric acid, boron magnesium fertilizer, and boron-containing superphosphate. Among these, boron magnesium fertilizer and calcium borate are primarily used as base fertilizers, with application rates ranging from 20–30 kg and 40–50 kg per 667 square meters respectively. Borax and boric acid are generally applied as root drenches at a concentration of 0.01%, or can be used for seed soaking with a 0.1% solution.
Molybdenum fertilizer is usually ammonium molybdate, which can be used as a base fertilizer, seed treatment, or foliar spray. The soaking concentration for seeds is 0.05–0.1%, with a soaking time of 12 hours. For foliar spraying, a concentration of 0.02–0.05% is recommended, and the best results are achieved during the seedling and tillering stages.
Copper fertilizer is commonly copper sulfate. As a base fertilizer, it is applied at a rate of 0.1–0.3 kg per 667 square meters. It can also be used for seed soaking with a 0.1% solution or as a root drench with a 0.05% solution.
These micronutrient fertilizers play a vital role in improving crop yield and quality by addressing specific nutrient deficiencies. Proper application methods ensure that plants receive the necessary nutrients efficiently, promoting healthy growth and higher productivity. Farmers should follow recommended guidelines to avoid over-application and ensure optimal results.
