How to fertilize strawberries scientifically? Please explain
Strawberry fertilization can be divided into base fertilizer and topdressing.
(1) Base fertilizer: Strawberry cultivation is dense, and replenishing fertilizer during the growing period is inconvenient, so the base fertilizer is best applied in sufficient quantity all at once together with nitrogen, phosphorus, and potassium fertilizers to meet the nutrient needs of the entire strawberry growth cycle. Generally, apply more than 5000 kg of base fertilizer per mu.
(2) Topdressing: The nutrients needed for strawberry growth and development and the flowering and fruiting period are supplemented by applying quick-acting fertilizers. The amount and frequency of topdressing depend on soil fertility and plant growth conditions, and about 3 to 4 times per year.
Strawberry growth in early spring mainly relies on the stored nutrients from the previous year. However, the period from before sprouting to the bud stage is a nutrient-demanding stage, so topdressing should be carried out together with irrigation to promote early leaf area formation and benefit flowering and fruit set. Usually, apply 7.5 to 10 kg of urea per mu, or 10-15 kg of compound fertilizer.
When strawberries enter the flowering stage, a topdressing should be carried out to meet the needs of plant growth and flowering and fruiting. This topdressing is mainly phosphorus and potassium fertilizers; the role of phosphorus is to promote root development and thereby increase fruit yield. During the fruit expansion stage, initial production stage, and peak production stage, the topdressing is mainly nitrogen and potassium fertilizers.
After the fruit is harvested, topdressing should be carried out to replenish the nutrient loss caused by growth and fruiting, so that the plants recover their growth vigor as soon as possible, while also promoting the occurrence of runners and new stems, promoting flower bud differentiation, and enhancing the plants' overwintering ability. This topdressing is generally indispensable and can be applied in shallow furrows.
