Before germination: When the buds begin to swell in early spring, quick-acting nitrogen fertilizer can be applied, and the fertilizer can be applied near the roots. Before flowering: Fertilizer can be applied two weeks before flowering, mainly external fertilization. Young fruit stage: Topdressing can be applied when the young fruit has just expanded. First turn over the soil and bury the fertilizer into a hole about 30-50 cm away from the plant. Berry ripening stage: When the fruits begin to turn color, fertilization should be applied not only to the roots, but also to the leaves.

1. Before germination

1. Before germination

In early spring, when the buds begin to swell, you can apply some quick-acting nitrogen fertilizer. Just apply the fertilizer near the roots. The roots can absorb it and promote new growth. The shoots become strong and strong, which can also play a role in increasing yields. Fertilization is very critical at this time.

2. Before flowering

In Fertilizer can be applied two weeks before flowering. At this stage, fertilizer is mainly applied outside the roots. After the pesticide is prepared, it is sprayed on the leaves. The main fertilizer is boron fertilizer, and some microbial sweeteners can also be selected. The effect of fertilization at this time is still significant, it can improve the progress of photosynthesis, and materials can also be transformed, which has good effects on later flowering, fertilization, fruit setting, etc.

3. Young Fruit Stage

After the flowers wither, when the young fruits have just begun to swell, topdressing can be applied, mainly with nitrogen fertilizers, or in combination with potassium fertilizers and phosphorus fertilizers. The fertilization method should be combined with plowing the soil. First, dig the soil deeply, and then bury the fertilizer into a small hole about 30-50 cm away from the plant.

4. Berry ripening period

When the fruits begin to turn color, it is also an important fertilization period, mainly applying fertilizers containing potassium and calcium. The fertilization method should not only be applied to the roots, but also sprayed on the leaves.
