1, less organic fertilizer. Bananas require large amounts of fertilizer, mainly organic fertilizers, supplemented by chemical fertilizers. Organic fertilizer is rich in organic matter and nutrients, and it has long-lasting effects on soil improvement. Early application of organic fertilizer, fertilizer supplements later, bananas can produce high quality.
2. The amount of potassium fertilizer is insufficient. Bananas are good potassium crops. The ratio of nitrogen, phosphorus and potassium absorption is 1:0.2:3.7. Pay attention to fertilization, increase potassium fertilizer. Compound fertilizers sold on the market generally contain less potassium. More phosphorus content. Therefore, in the application of chemical fertilizers, high-potassium compound fertilizers or potassium fertilizers should be used to balance nutrients and meet the normal growth and development of bananas.
3, fertilization does not cover the soil. Banana roots grow under the soil and grow downwards. The nutrients can only be absorbed by touching the roots under the soil. The farmer plans to spread the fertilizer on the surface of the soil, and the fertilizer is sprayed by the wind and rain, most of the nutrients are evaporated, lost, and fertilizers are used. The force is low, so fertilization must be done with deep soil.
