Vegetable foliage dressing considerations
Appropriate concentration of spray fertilizer concentration to foliar fertilizer: 1% to 2% of urea; 0.2% to 0.5% of potassium dihydrogen phosphate, 0.2% to 0.3% of ammonium sulfate; 0.03% to 0.1% of borax; 1% of superphosphate ~ 2%; rice vinegar 0.3%; rare earth 0.3% ~ 0.1%. The spraying site should be foliar dressing fertilizer spraying the key parts of the young stems and leaves of vegetables, and the front and back should be sprayed, not to miss the spray or re-spray. The application period is suitable for leafy vegetables generally applied in the early and middle growth period; Solanaceae, melons, beans, rhizomes are generally applied in the middle and later stages. Spraying times should be appropriate for general foliar application 2 to 3 times, once every 7 to 10 days. Application time should pay attention to the foliar dressing more choices in sunny afternoon when the sun is not strong when spraying, in order to facilitate the extension of the fertilizer on the vegetable moist time, improve fertilizer efficiency, such as spraying 3 hours after the rain, after sunny days to make up the spray, However, the concentration should be reduced appropriately. Fertilizer mix should be cautious when dressing vegetable leaves, the rational use of two or more than two kinds of fertilizer, increase production effect is significant. However, they cannot be used arbitrarily. For example, potassium dihydrogen phosphate cannot be mixed with rare earths. The filtered human waste cannot be mixed with the ash extraction solution. Zinc phosphate cannot be mixed with superphosphate. Disclaimer: Some articles in this website have been transferred from the Internet.
