Special controlled release fertilizer for sugarcane and preparation method for fertilizer

Abstract

The present invention provides a special controlled release fertilizer for sugarcane and a preparation method for the fertilizer, and belongs to the technical field of fertilizers. The fertilizer comprises an outer wrapping layer and an inner fertilizer particle composed of a natural polymer coating material. The fertilizer particle is prepared by mixing the following raw material components: urea, calcium superphosphate, ammonium chloride, potassium chloride, humic acid, diammonium phosphate, agricultural rare earth, borax or boric acid, copper sulfate, zinc sulfate, magnesium sulfate, ferric nitrate, ammonium molybdate, compound sodium nitrophenolate, polyglutamic acid, and an adhesive. The fertilizer contains abundant and comprehensive nutrient components, can satisfy the requirement on various nutrients in a normal growth process of sugarcane, and the fertilizer enhances the disease resistance, the drought resistance and tje lodging resistance of the sugarcane, and increases the yield per mu; the fertilizer has a good controlled release effect, effectively reduces the fertilizer nutrient loss, and increases the fertilizer utilization; and the selected natural polymer coating material has an excellent biodegradation performance, causes no ecological pollution, and has an environmental-friendly effect.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special controlled-release fertilizer for sugarcane and a preparation method thereof. Background technique [0002] Sugarcane is the general term for the genus Saccharum. The most common edible sugarcane in China is bamboo cane. Sugarcane is suitable for planting in places with fertile soil, sufficient sunlight, and large temperature differences between winter and summer. Sugar cane is a temperate and tropical crop that is used as a raw material for the manufacture of sugar and for ethanol as an energy substitute. There are more than 100 countries producing sugar cane in the world, and the largest sugar cane producing countries are Brazil, India and China. Sugarcane is rich in sugar and water, and also contains various vitamins, fats, proteins, organic acids, calcium, iron and other substances that are very beneficial to human metabolism. It is mainly used fo...

Problems solved by technology

When fertilizing sugarcane, if you only pay attention to the application of a single fertilizer, excessive application of a single fertilizer, unreasonable ratio of nitrogen, phosphorus, and potassium, lack of trace element fertilizers and organic matter, etc., will lead to soil compaction, yellow sugarcane leaves, Small face, slow growth, small stem, light weight, poor disease resistance, prone to various diseases and insect pests, and finally low yield and low sugar content of sugarcane

At the same time, after fertilizer application, especially in the rainy areas in the south, the soluble inorganic fertilizer will dissolve quickly, which reduces the effect of fertilizer application on the one hand, causes waste of fertilizer, and pollutes surrounding water bodies
