What fertilizer is best to apply to strawberries during the flowering and fruiting period? Please explain
Strawberries bloom and fruit continuously, with many flowers and a large fruit set, and a long flowering and fruiting period, so they consume a lot of phosphorus and potassium fertilizer. During the flowering and fruiting period, once phosphorus is deficient and potassium is low, cold resistance will decrease, fewer flowers will form, flower buds will be weak, and flowering and fruiting will be affected; not only will the fruit-setting rate be low and the fruit prone to deformities, but the coloring will also be poor, the sugar content will drop, the taste will be bland, and the fruit will be prone to rotting and spoilage and will not keep well in storage. Therefore, during the flowering and fruiting period of strawberries, attention should be paid to increasing the application of phosphorus and potassium fertilizer to prevent the strawberry plants from being deficient in phosphorus and low in potassium. The specific fertilization method is as follows:
During the flowering and fruiting period of strawberries, a phosphorus and potassium fertilizer must be applied to the roots once every 15-20 days, each time applying 40-50 kg of potassium dihydrogen phosphate per mu, or 70-80 kg of composted and thoroughly decomposed cattle bone meal or pig bone meal, diluted with 80-100 times clean water, and then evenly drenched onto the soil around the strawberry plant roots. In addition, an 800-times aqueous solution of Xingpeng Phosphorus and Potassium No. 1, or a 25-30 times clear leachate of superphosphate and clean pure plant ash, should be sprayed once every 7-10 days, evenly wetting all leaves, flower buds, flowers and fruits, until water droplets begin to drip down; this supplements phosphorus and potassium fertilizer through the leaves and rapidly raises the phosphorus and potassium levels of the strawberry plants.
