Spraying foliar fertilizer on vegetables not only saves fertilizer and quick effect, but also increases production and income. However, the application of foliar fertilizer should be well controlled by the spraying technology and spraying time. The choice of fatness should be different from that of the food before it can receive good results.
1, cabbage, celery, spinach and other leafy vegetables such as spraying should be based on urea, ammonium sulfate-based. Spraying concentration of urea should be controlled within 2%. Ammonium sulfate should be controlled within 1.5%. Spraying is usually performed at intervals of 10 days. If 500 times of edible vinegar is added during spraying, the effect is more significant.
2. Tomatoes, peppers, eggplants, fruits, and other melons and fruits Such vegetables have a more balanced demand for nitrogen, phosphorus, and potassium, and nitrogen, phosphorus, and potassium three-element compound fertilizers should be sprayed. Can be 1% -2% of urea mixed with 0.3% -0.4% of potassium dihydrogen phosphate into a composite solution spray. It is usually sprayed once in the early and late stages of growth.
3, garlic, onion, radish and other root vegetables Such vegetables require more phosphorus, potassium, foliar spray can be used 0.3% of potassium dihydrogen phosphate and 10% of the ash leaching liquid mixed spraying, spraying each season 3 -4 times.
The spraying of foliar fertilizer on vegetables should be done in sunny afternoon when the sun is not strong or cloudy. Each foliar fertilizer sprays about 40 kg of good fertilizer solution every time, so as to limit the spraying of vegetable leaves. When foliar fertilizer is sprayed, according to the demand of different vegetables for trace elements, applying a certain amount of micro-fertilizer can increase the production value, but the concentration should not be too high. Special attention should be paid to the fact that when spraying fertilizers, acidic and alkaline fertilizers cannot be mixed.
