1、 Fertilization tips

1. Base fertilizer: at the beginning of planting greenhouse strawberries, some base fertilizer should be applied to the soil, usually 5000 kg of farm fertilizer per mu

2. Topdressing: in order to make it grow and bear fruit better, an appropriate amount of compound fertilizer should be applied. When the fruit expands continuously, some compound fertilizers with high nitrogen content can be applied

3. Foliar fertilizer: during fruit growth, it is necessary to spray some potassium dihydrogen phosphate or urea, which can improve the quality of strawberries. Usually in the middle and late stage of growth, spray 3-4 times, which can make strawberries bear more fruit and have higher quality

2、 Fertilization time

When base fertilizer is applied to it, it is just added to the soil before planting. Daily topdressing should be carried out when there is no strong light. If it is exposed to strong light after fertilization, the heat generated will be harmful to strawberries. When spraying foliar fertilizer, it should avoid noon, which can be carried out in the evening of sunny weather or cloudy days

3、 Precautions

When topdressing it, the amount of fertilizer should be strictly controlled. Do not apply too much fertilizer, which will cause fertilizer damage
