Greenhouse strawberry fertilization plan, when to fertilize

1. Fertilization tips

1. Base fertilizer: When you first start planting greenhouse strawberries, you should apply some base fertilizer to the soil. Usually, 5,000 kilograms of farmyard manure should be applied per acre.

2. Top dressing: In order to make it grow and bear fruit better, apply an appropriate amount of compound fertilizer. When the fruit continues to expand, you can apply some compound fertilizer high in nitrogen content.

3. Foliar fertilizer: During the fruit growth period, you need to spray some potassium dihydrogen phosphate or urea to improve the quality of strawberries. Usually, spraying 3-4 times in the middle and late stages of growth will be enough to produce more strawberries and have higher quality.

2. Fertilization time

When applying base fertilizer, just add it to the soil before planting. Daily topdressing should be done when there is no strong light. If the strawberries are exposed to strong light after fertilization, the heat generated will be harmful to the strawberries. When spraying foliar fertilizer, you should avoid noon and can do it in the evening on a sunny day or on a cloudy day.

3. Notes

When applying fertilizer, the amount of fertilizer should be strictly controlled. Do not apply excessive fertilizer, which will cause fertilizer damage.
