The use of foliar fertilizers can provide nutrients to maize, improving the growth and yield of crops. Here are some tips for using foliar fertilizer on corn that we hope will help you:
Timing of application: Timely application of foliar fertilizer is essential to increase corn yields. Generally, it is recommended to apply at the key stages of maize growth, such as seedling stage, jointing stage, heading stage and grain filling stage. These are the times when corn has a higher nutrient requirement.
Choose the right foliar fertilizer: The choice of foliar fertilizer should be based on the nutrient requirements of the corn crop. For example, at the seedling stage of corn, you can choose to spray *** foliar fertilizer containing amino acids + potassium dihydrogen phosphate;In the grain filling stage, you can use *** authentic slow-release nitrogen fertilizer + amino acid-containing foliar fertilizer + chelated zinc, iron, manganese and boron to supplement nutrients and trace elements and improve the growth effect of corn.
Adjust the concentration to use: Dissolve the appropriate amount of foliar fertilizer in a certain amount of water according to the packaging instructions of the foliar fertilizer, and follow the recommended dilution ratio. The specific use may vary according to factors such as the type of crop, growth stage and soil conditions, and can be used after consulting a technician.
Spraying technique: Use a sprayer to spray the diluted foliar fertilizer evenly on the leaves of the corn. Spray the fertilizer as evenly as possible to ensure adequate coverage of the surface of each leaf. It is best to spray on both sides when spraying, which can improve the absorption effect of foliar fertilizer.
Pay attention to the amount and frequency of fertilization: When applying foliar fertilizer, the amount and frequency of fertilization should be adjusted appropriately according to the needs of crops and the actual situation. Generally, sprays are applied every 7 to 14 days. However, the exact amount and frequency of fertilization can be adjusted depending on factors such as the type of fertilizer used, crop growth and soil conditions.
Please note that the above recommendations are for reference only. The specific method of use and dosage should be determined according to the variety of corn, the growth stage, the soil conditions, and the foliar fertilizer product. In order to obtain good results, it is recommended that you consult a technical staff to adjust the use method according to the actual situation.
