Before flowering, 10 kg of urea and 25 kg of phosphate fertilizer were applied per mu. Apply urea and ammonium sulfate 10kg / mu, phosphate fertilizer 15kg / mu, potassium chloride 7.5kg / mu after fruit. Pregnant flower fertilizer is mainly applied with phosphorus and potassium fertilizer.

It is necessary to apply pre-flower fertilizer, post-fruit fertilizer, pregnant flower fertilizer and extra-root topdressing.

Apply urea and ammonium sulfate 10kg / mu, phosphate fertilizer 15kg / mu, potassium chloride 7.5kg / mu after fruit. Pregnant flower fertilizer is mainly applied with phosphorus and potassium fertilizer, combined with a small amount of nitrogen fertilizer. Extra-root topdressing should be applied according to the growth of strawberries.

1. Pre-flowering fertilizer.

After the strawberries began to grow in early spring and before flowering (about mid-March), it was carried out to meet the various nutritional needs of flowering. Apply 10 kg of urea and 25 kg of phosphate fertilizer per mu, ploughing and irrigation after fertilization.

2. Fat after fruit.

After a large number of strawberry fruit, there is a lack of nutrients in the plant. In order to restore plant growth as soon as possible, form more new leaves and new roots, and create conditions for flower bud differentiation in autumn, potassium fertilizer should be properly increased this time. Each mu can apply urea and ammonium sulfate 10kg, phosphate fertilizer 15kg, potassium chloride 7.5kg.

3. Pregnant flower fertilizer.

It is carried out before the flower bud differentiation of strawberry, which ensures the normal growth and flower bud differentiation of strawberry plant. Mainly apply phosphorus and potassium fertilizer, combined with a small amount of nitrogen fertilizer.

4. extra-root topdressing (that is, foliar spraying).

According to the growth of strawberries, urea, potassium dihydrogen phosphate, zinc sulfate, ferrous sulfate, borax, magnesium sulfate and other fertilizers can be selected to spray nitrogen, phosphorus, potassium and some trace elements on the leaves of strawberries from budding to the end of flowering, generally 2 or 3 times, and the spraying time should be in the evening of cloudy or sunny days.
