Onion fertilization time1. Onions need to be fertilized 15-20 days after planting to promote continued root growth. You can apply 5-6 kg of urea per mu and water in time after spreading to facilitate root absorption. 2. Onions should be applied with fertilizer one month after planting, mainly nitrogen fertilizer, which can ensure the growth needs of the functional leaves above the ground. Apply 5 kg of potassium sulfate and 5-6 kg of urea per mu. 3. After the onion has grown 8-10 tubular leaves, apply the top fertilizer when the bulb begins to grow and expand. Do not apply too much nitrogen fertilizer, otherwise it will become "greedy for green" and affect the harvest. What fertilizer to use for onionsOnion fertilization can be mainly done with organic fertilizer, biological fertilizer, bio-organic-inorganic compound fertilizer, commercial organic fertilizer, and organic-inorganic compound fertilizer. Use an appropriate amount of potassium sulfate type compound fertilizer as base fertilizer and bottom fertilizer, and use appropriate foliar fertilizer to promote its growth. Onion Fertilization MethodFertilization is a very important part of onion cultivation. It is best to use farmyard manure or organic compost as the main fertilizer, supplemented by an appropriate amount of chemical fertilizer, which can promote the healthy growth of the plants. Onion Fertilizer PrecautionsFertilize according to the growth of onions. Quick-acting nitrogen fertilizer should be applied during the vegetative growth period to promote plant growth. Less water and fertilizer should be used in the early growth stage. For those planted in spring, the first fertilizer should be applied 2 weeks after planting. For those planted before winter, the first fertilizer should be applied when the onions turn green again in the following spring. |
