Strawberry is a perennial herb that absorbs large amounts of nutrients from the soil. Strawberry fertilization should be based on basal fertilizer, generally about 5000 kg of organic fertilizer applied in Mushi, together with nitrogen, phosphorus, potassium and other fertilizers to meet the normal growth needs of plants. In the case of insufficient fertilizer for base fertilizer, it should be top-dressed according to the growth conditions of the strawberry in different periods. Strawberry top dressing should grasp three periods.
One is before flowering. In early spring, after the strawberry grows, it begins to grow before flowering. Mushi urea 10 kg, superphosphate 25 kg to meet the needs of flowering for various kinds of nutrition.
The second is fat after fruit. After a large number of strawberry results, the plant nutrient deficiency, in order to restore plant growth as soon as possible, the formation of new leaves and new roots, to create conditions for the autumn flower bud differentiation, general mu application of urea 10-15 kg, superphosphate 15-20 kg, potassium chloride 7.5 - 10 kg.
The third is pregnant fertilization. The differentiation of strawberry flower buds is performed before the differentiation, which can guarantee the normal growth and flower bud differentiation of strawberry plants. The main application of phosphorus and potassium fertilizer, with a small amount of nitrogen fertilizer.
