Now is the receiving season of strawberries. At this time, we need to take care of it. Strawberry grows to absorb nutrients from the soil, so the high yield of strawberries is inseparable from the soil. So how should the strawberry field be fertilized?
Strawberry grows for a certain period of time. Since the soil can not provide enough nutrients for strawberries, we need to fertilize the strawberries to meet the growth needs. We must grasp the several periods of the strawberries and make timely fertilizers. Linyi Fertilizer Network Copyright
1. Fertilization before flowering is carried out in the early spring after the strawberry begins to grow until before flowering (about mid-March) to meet the needs of flowering for various nutrients. Apply 10 kg of urea per acre, 25 kg of phosphate fertilizer, and cultivate and irrigate after fertilization. Linyi Fertilizer Network Copyright
2. After the results of fertilization of strawberry a large number of results, the plant lacks nutrients, in order to restore plant growth as soon as possible, more new leaves and new roots are formed, creating conditions for flower bud differentiation in autumn, this time the topdressing should increase potassium fertilizer appropriately. Each mu can be applied with urea and ammonium sulfate 10 to 15 kg, phosphate fertilizer 15 to 20 kg, and potassium chloride 7.5 to 10 kg. Linyi Fertilizer Network Copyright
3. Pregnancy fertilization is carried out before strawberry flower bud differentiation, which guarantees the normal growth and flower bud differentiation of strawberry plants. Mainly applied phosphorus and potassium fertilizer, combined with a small amount of nitrogen fertilizer. Linyi Fertilizer Network Copyright
The above is the fertilization method of strawberry in each period. The strawberry fertilization should be based on the base fertilizer. The fertilizer of 5,000 kg per mu should be applied, and the nitrogen, phosphorus and potassium quick-acting fertilizer should be applied to meet the normal growth needs of the plant. The effect of nitrogen fertilizer is to promote the formation of a large number of leaves and stolons, strengthen vegetative growth, increase fruit and increase yield; phosphate fertilizer can promote flower bud differentiation and increase fruit set rate; potash fertilizer mainly promotes fruit ripening, increases fruit sugar content and improves fruit quality. Therefore, according to the growth of strawberry, urea, potassium dihydrogen phosphate, zinc sulfate, ferrous sulfate, borax, magnesium sulfate and other fertilizers can be used to spray nitrogen, phosphorus, potassium and some trace elements during the period from strawberry bud to flowering. Fertilizer can increase production. Linyi Fertilizer Network Copyright
