What are the latest precautions for fertilizing strawberries?
Strawberry is a particularly popular fruit, not only because of its luscious appearance, but also for its sweet-and-sour taste. People of all ages love to eat them, so strawberries fetch a relatively high price on the market and have good economic returns. If you want strawberries to grow well, fertilization is fairly important, so what should we pay attention to when fertilizing strawberries? Let's take a look together.
1. Whether to fertilize during the flowering period
1. Strawberries may need topdressing during the flowering period, usually with additional phosphorus and potassium fertilizer, because once the flowering and fruiting stage lacks the two fertilizers phosphorus and potassium, the cold resistance of the strawberries will be reduced, few flowers will form and the flower buds will be weak, affecting flowering and fruiting. This not only lowers the fruit-setting rate, but also leads to poor coloring and lower sugar content in summer, making the fruit highly prone to rot and deterioration and poor for storage and fresh-keeping. Therefore, during the strawberry season, be sure to apply additional phosphorus and potassium fertilizer to prevent phosphorus and potassium deficiency from affecting the yield and quality of the strawberries.
2. During the flowering and fruiting period, be sure to apply phosphorus and potassium fertilizer once every 15-20 days, applying 40-50 kg of potassium dihydrogen phosphate per mu each time, or 70-80 kg of decomposed bone meal, diluted with water 80-100 times, then evenly drenched onto the soil around the plant roots. In addition, a low-concentration potassium dihydrogen phosphate solution can be sprayed once every 7-10 days, evenly sprayed on all leaves, flower buds, flowers and fruits, until water droplets begin to drip.
2. Fertilization precautions
1. When laying drip irrigation pipes, the drip holes should face upward, so that sediment does not clog the drip holes or strawberry roots grow into the drip holes and cause blockage.
2. The spacing of the drip holes in the drip irrigation pipe should be reasonable, ensuring that the wet cross-sections formed by the drip holes can overlap during drip irrigation.
3. If it is greenhouse strawberry topdressing in the north, the water used should preferably be above 20 degrees, to avoid low temperatures reducing root growth.
4. After strawberries flower and set fruit, every watering should be accompanied by fertilizer. Before fertilizing, first water for 20 minutes, then fertilize along with the water, and after fertilizing, water again for 10 minutes.
5. Throughout the entire growth period of strawberries, a single high-potassium fertilizer, such as potassium sulfate, should preferably not be used more than 3 times.
6. Watering and topdressing should be determined according to the weather, soil fertility conditions and seedling growth conditions.
7. When topdressing, pay attention to supplementing trace elements such as calcium, boron, iron and magnesium.
