Abstract

The invention discloses a synchronous slow-release fertilizer special for super hybrid rice, which consists of the following fertilizer raw materials in part by weight: 0.1800 to 0.3374 part of urea-formaldehyde coated urea (7-0-0), 0.1800 to 0.1900 part of monoammonium phosphate, and 0.5000 to 0.55000 part of tower granulation nitrogen and potassium coated sulfur fertilizer (added with medium silicon and zinc). The synchronous slow-release fertilizer special for the super hybrid rice of the invention is suitable for the super hybrid rice, and is characterized by reduction in nitrogen pollution and loss, high fertilizer utilization ratio and improvement on grain yield and quality.

Description

technical field [0001] The invention relates to a special fertilizer for rice, in particular to a synchronous slow-release super hybrid rice special fertilizer and a preparation method thereof. Background technique [0002] Super hybrid rice has the advantages of large panicle, lodging resistance, strong photosynthetic ability of leaves, wide adaptability, and strong advantages. However, super hybrid rice has a large biological yield and requires a large amount of fertilizer, which will definitely affect the benefits of rice planting. Moreover, farmers' rice planting habits of fertilization and excessive use of nitrogen fertilizers have caused problems such as nitrogen surface pollution. [0003] China is currently the country that uses the most nitrogen fertilizer in the world. Excessive nitrogen application not only increases the cost of agricultural production, but also has a serious negative impact on the environment. The phenomenon of greatly increasing the level of n...
