What fertilizer is best for growing strawberries? Choosing the right fertilizer is key
The strawberry is a perennial herbaceous plant of the genus Fragaria in the rose family (Rosaceae), with stems shorter than or nearly equal to the leaves, densely covered with spreading yellow soft hairs, flowers borne in cymes, and fruit that is an aggregate fruit. It is widely cultivated throughout our country, is rich in nutrients, contains a variety of nutritional substances, and has health benefits, giving it extremely high cultivation value. Let's take a look below at what fertilizer is best for strawberries!
Do strawberries need a lot of fertilizer?
Strawberries flower and fruit continuously, and from planting to flowering and fruiting they need a fairly large amount of fertilizer. In addition to applying sufficient base fertilizer, fertilizer must also be replenished at the right time. During the fruit enlargement stage and the beginning of harvest, apply 10 kg per mu of strawberry-specific fertilizer or diammonium phosphate. Combined with watering, trench application in the form of a 200-fold liquid fertilizer works better. For fields with good growth, spraying only 0.1-0.2% potassium dihydrogen phosphate 2-3 times also has a certain yield-increasing effect; in principle, do not spray during the flowering stage. The fertilization principle for fruit-harvesting fields is appropriate N, heavy P and K, and a reasonable ratio must be maintained to obtain higher yield and maximum benefit.
What fertilizer is best for strawberries?
1. Nitrogen fertilizer: Nitrogen fertilizer can promote the vigorous growth of strawberry seedlings. Moldy and insect-damaged beans, peanuts, and melon seeds that can no longer be eaten are all very good nitrogen fertilizer materials.
2. Phosphorus fertilizer: Phosphorus fertilizer can make strawberries brightly colored, glossy, and plump. Fish bones, eggshells, and meat bones are all very rich in phosphorus.
3. Potassium fertilizer: Potassium fertilizer can improve strawberries' ability to resist pests and diseases. Water from washing rice, leftover tea water, and water from rinsing milk bottles are all very good potassium fertilizer materials.
How should strawberries be fertilized properly?
1. Base fertilizer: Before planting strawberries, plow the soil deeply 25-35 cm, and together with plowing apply per mu 450-500 kg of commercial organic fertilizer or 3500-4000 kg of high-quality farmyard manure, 5-6 kg of urea, 15-20 kg of diammonium phosphate, and 5-6 kg of potassium sulfate.
2. Topdressing: From when strawberries begin to grow until before the flowering stage, apply per mu 9-10 kg of urea and 4-6 kg of potassium sulfate; during the berry enlargement stage, apply per mu 11-13 kg of urea and 7-8 kg of potassium sulfate; after heavy fruiting, topdress as needed.
3. Foliar fertilizer: Spraying humic acid organic-inorganic liquid compound fertilizer on the leaves before and after the flowering stage of strawberries can increase the fruit-setting rate, improve fruit quality, and increase single fruit weight. Spraying 0.2% calcium sulfate plus 0.05% manganese sulfate at the early flowering stage and full flowering stage can increase yield and fruit storage performance.
