The banana has a short growth cycle and a large demand for nutrient elements. The nutritional requirements of different growth periods have a significant stage. The nutritional requirements are different in different periods such as germination, seedling, fruit growth, and harvest.

base fertilizer:

Each plant is applied with Huaqiang Compound Fertilizer (16-16-16) 0.5-0.8 kg combined with decomposed organic fertilizer, mixed and applied to the planting hole, spread 5-10 cm of crushed soil on it, and then transplanted, banana root system when transplanted It should not be in direct contact with fertilizer.

top dressing:

1. Banana seedlings are relatively tender and weak at the early stage, with poor absorption.

2. After the first 1-2 new leaves are unfolded after transplanting, fertilize about 50 cm in height. Fertilization per plant (20-8-15) is about 0.2-0.3 kg, and it is required to apply once every two weeks. When the false stem of the plant is more than 50 cm, it will be sprinkled, mainly based on the high-nitrogen compound fertilizer formulated with compound fertilizer (20-8-15), combined with soil cultivation. Spray foliar fertilizer according to plant growth to make the growth uniform and consistent.

3. The demand for nutrients in the period before the banana buds are more uniform, it is recommended to fertilize frequently (17-7-25), 0.2-0.3 kg per plant each time.

4. This period is the key time to determine the yield of bananas after bud extraction and before harvesting, and bananas have strong absorption of fertilizer and water, so it is recommended to re-fertilize (17-7-25), or a similar ratio of low P and high The potassium sulfate compound fertilizer of K is used in an amount of 0.25-0.35 kg per plant.
