Strawberry is a perennial herbaceous plant that requires nitrogen, phosphorus, potassium, boron, magnesium, zinc, iron, calcium and other trace elements. The characteristics of fertilizer required in different growth stages are not good. Phosphorus is needed in the early stage, and a large amount of nitrogen is needed in the early and middle stages. Potassium is needed in the whole growth period. Linyi Fertilizer Network Copyright

The total fertilization amount of strawberry in the whole growth period is 3000-3500 kg of organic fertilizer (or 450-500 kg of commercial organic fertilizer), 14-16 kg of nitrogen fertilizer, 6-8 kg of phosphate fertilizer, and 8-10 kg of potassium fertilizer. Organic fertilizer is used as base fertilizer, nitrogen and potassium base fertilizer and secondary topdressing. The ratio of fertilization is 3:3:4, phosphate fertilizer is used as base fertilizer, and fertilizer and farmyard manure (or commercial organic fertilizer) are mixed.
