Strawberry fields should be planted on plots with slightly higher terrain, flat ground, convenient drainage and irrigation, rich organic matter, and good ventilation. This article focuses on how to apply fertilizer to strawberries? What should I pay attention to when fertilizing strawberries?
Fertilization Methods for Strawberries
1. Before planting, it is necessary to apply organic fertilizer in combination with deep plowing and soil preparation. Each mu can be applied with 4-8 tons of manure and 80-100 kilograms of calcium phosphate. For slightly acidic soils, about 100 kg of lime can be applied per mu.
2. Top dressing usually takes about 1-3 times. Before flowering and early spring sprouting, topdressing should be conducted once each. Generally, 45% compound fertilizer should be applied 10-15 kg per mu, or urea 8-10 kg, plus a certain proportion of phosphorus and potassium fertilizer. Another dressing can be used 2 weeks before harvest or 2-3 weeks after flowering.
Precautions for Strawberry Fertilization
1. Strawberry has a shallow root system at the early stage of growth, but it is not developed at all. Therefore, it is necessary to apply a small amount of fertilizer in the early stage. After flowering, there is a large demand, and the amount of fertilizer can be increased according to the plant's requirements for various elements.
2. The fertilization time can be selected around 10:00 a.m. Note that fertilization must not be allowed after 2:00 p.m., otherwise it can easily lead to accumulated fertilizer burning roots and affecting growth.
3. During the flowering and fruiting period of strawberries, it is also necessary to apply reasonable fertilization to make the strawberry plants grow more robust. When applying fertilizer, it is necessary to pay attention to applying thin fertilizer, as excessive fertilizer can burn the roots and damage the plants.
