Strawberry picking time is longer, plants often appear premature aging, which affects the yield and quality of berries. Therefore, the use of basal fertilizer for strawberry must have long-lasting fertilizer effect as long as no fertilizer damage occurs. When applying basal fertilizer, the following points should be noted:

(1) The amount of basal fertilizer should be sufficient, mainly organic fertilizer. When the target output is 1500 kg per 667 square meters, the amount of base fertilizer is 400 kg of manure, 200 kg of cake fertilizer, 32 to 40 kg of compound fertilizer (15% of nitrogen, phosphorus, and potassium) and 5 to 10 kg of urea.

(2) Manure must be decomposed. Fresh manure can not be directly used as base fertilizer, so as not to cause burning seedlings and dry heart.

(3) Basal fertilizer should be fully mixed with soil. The strawberry roots are shallow, and most of the roots are distributed in layers of 0 to 20 cm deep. Basal fertilizer can not be applied too deep, it should be applied in the depth of 10 to 20 cm deep soil. Pay attention to make basal and earth evenly.

(4) Appropriate fertilizer mix. The available nitrogen fertilizer in basal fertilizer should not be too much, so as to avoid excessive growth of plants and to inhibit the differentiation of alfalfa buds.
