Abstract

The invention discloses a banana controlled-release fertilizer and a preparation method thereof, and belongs to the technical field of fertilizer preparation. The banana controlled-release fertilizer is prepared from the following raw materials in parts by weight: 80-120 parts of a wrapping material and 200-1200 parts of fertilizer particles; the banana controlled-release fertilizer is prepared by the steps of granulating, drying, cooling, wrapping and the like. The fertilizer disclosed by the invention is moderate and stable in controlled-release rate and balanced in nutrition, and is capable of effectively reducing the loss rate of the fertilizer, improving the utilization efficiency of the fertilizer, promoting quick and healthy growth of bananas, and improving the banana yield by 3.1-3.8% and the banana sugar content by 0.24-0.32%.

Description

【Technical field】 [0001] The invention belongs to the technical field of fertilizer preparation, and in particular relates to a banana controlled-release fertilizer and a preparation method thereof. 【Background technique】 [0002] Banana is a fast-growing economic plant widely planted in southern my country. It requires a large amount of nutrients during its growth. Therefore, it must be fertilized in sufficient quantities during its growth to achieve a high banana yield. The rapid growth period of bananas is in summer, which is the rainy season in southern my country. On the one hand, it is not convenient for fertilization work, and on the other hand, the fertilizer applied is easy to be lost with frequent rainfall, which affects the efficiency of fertilization. Soluble inorganic Fertilizer will dissolve at a relatively fast speed, resulting in waste of fertilizer and eutrophication of water bodies, which greatly restricts the promotion and use of banana-specific fertilizers...
