Rational fertilization of strawberries promotes high yield

Reasonable topdressing: In order to meet the demand for various nutrients during the flowering period, generally after the strawberry begins to grow and before the flowering period, 10~15 kg of compound fertilizer per mu is applied, and the amount of base fertilizer is sufficient. During the expansion period of the berry, about 15 kg of high-nitrogen potassium compound fertilizer can be applied. After a large number of strawberries, the nutrients in the plant are lacking. In order to restore the growth of the plant as soon as possible, new roots of new leaves should be formed, and topdressing should be carried out according to the needs. The specific amount of fertilization should be determined according to the amount of fruit collected, and more fruits should be fertilized, and less seeds should be less fertilized. In combination with the above-mentioned spraying in the flowering period, the young fruit period, and the fruit expansion period, the strong fruit stalk is added to increase the nutrient delivery amount. Anti-falling flowers, fruit drop, cracked fruit, stiff fruit, and deformed fruit make the fruit colorful, fruity and taste good.
Spraying outside the root: According to the growth of the strawberry in the middle and late stages, the external top dressing (ie foliar spray) method is used for assisted fertilization. According to the need to spray new high-fat film 3~4 times in the middle and late growth stages, the fruit setting rate can be improved, the fruit quality can be improved, the weight of single fruit can be increased, and the result period can be prolonged. In addition, foliar spray should be carried out in the evening on a cloudy or sunny day, because the amount of evaporation at noon is large.
