Strawberry Potassium Phosphate
The continuous flowering of strawberry results in less phosphorus deficiency during the flowering period, which will reduce the cold resistance, with less flowers, weak flower buds, affect the flowering results, not only the fruit setting rate is low, and the coloring is not good, the sugar content is decreased, and the taste is light , perishable, impatience storage and preservation. Therefore, during the flowering period of strawberry, it is necessary to pay attention to the application of phosphorus and potassium fertilizers to prevent the phosphorus deficiency and potassium deficiency of strawberry plants. Specific fertilization methods are as follows:
During the fruiting period of strawberry flowering, it is necessary to apply phosphorus and potassium fertilizer once every 15 to 20 days, applying 40-50 kg of potassium dihydrogen phosphate per mu, or applying 70-80 kg of cooked bovine bone meal or pork bone meal. Diluted with water 80 to 100 times, evenly applied in the soil around the roots of strawberry plants. In addition, spray 800 times Starch Phosphate No. 1 water solution every 7 to 10 days, or 25 to 30 times superphosphate and clean pure plant ash to soak the clear liquid, evenly spray all the leaves, buds, flowers and fruits. It is advisable to start dropping drops of water and supplement phosphorus and potassium fertilizers from the foliage.
