Base fertilizer: Before strawberry planting, 450-500 kg of organic fertilizer or 3500-4000 kg of high-quality farmyard manure, 5-6 kg of potassium sulfate, 0/5-20 kg of diammonium phosphate/kloc, and 5-6 kg of urea must be applied with deep tillage.

Topdressing: 4-6 kg of potassium sulfate and 9- 10 kg of urea can be applied to strawberries from the growth period to the flowering period.

Foliage fertilizer: Humic acid organic and inorganic liquid fertilizer can be sprayed on strawberry leaves before and after flowering, which can not only improve fruit setting rate, but also improve fruit quality and increase yield.

1. What fertilizer is used for strawberries?

1, base fertilizer

Before planting strawberries, the soil must be deeply ploughed for about 25-30cm, and then combined with deep ploughing and fertilization, 450-500kg of organic fertilizer or 3500-4000kg of high-quality farmyard manure, 5-6kg of potassium sulfate, 0/5-20kg of diammonium phosphate/kloc and 5-6kg of urea are applied.

2. Surface treatment

(1) 4-6 kg of potassium sulfate and 9- 10 kg of urea can be applied to strawberries from growing period to flowering period.

(2) Potassium sulfate 7-8kg, urea11-13kg can be applied per mu in the berry expansion period, and topdressing can be carried out according to specific conditions after a large number of fruits are produced in the later period.

3. foliar fertilizer

(1) Humic acid organic and inorganic liquid fertilizer can be sprayed on strawberry leaves before and after flowering to improve fruit setting rate, fruit quality and yield.

(2) Spraying 0.2% calcium sulfate and 0.05% manganese sulfate at the initial and full flowering stages is beneficial to improve fruit yield and storage performance.

Second, do strawberries need a large amount of fertilizer?

1. Strawberries need a lot of nutrition from field planting to flowering and fruiting. In addition to applying sufficient base fertilizer, appropriate topdressing must be carried out.

2. During the fruit expansion period and harvest period, strawberry special fertilizer or diammonium phosphate can be applied per mu 10 kg, and 200 times liquid fertilizer combined with watering can be applied in furrow.

3. Generally, it is only necessary to spray 0. 1-0.2% potassium dihydrogen phosphate for about 2-3 times in the field with good growth, which has a certain yield-increasing effect, and it is not necessary to spray it in flowering period in principle.

4. Fertilization in fruit-picking areas must follow the appropriate hydrogen fertilizer, re-apply phosphorus and potassium fertilizer, and maintain a reasonable ratio to improve yield and quality.
