Embodiment

[0029] Examples: 1. The synchronous slow-release super hybrid rice special fertilizer with a total nutrient content of 41.65% (20-9-11.1-0.55) per ton produced is composed of the following fertilizer raw materials, urea-formaldehyde-coated urea (7-0-0) 0.199, monoammonium phosphate granules (11-47-0) 0.190, high tower nitrogen potassium fertilizer (30-0-20-2-1) 0.550.

[0030] The synchronous slow-release special fertilizer for super hybrid rice of the present invention is characterized in that: every 1 ton produced is a special fertilizer for synchronous slow-release super hybrid rice with a total nutrient content of 39.68% (19.26-8.46-10.4-1.04-0.52). It is composed of the following parts by weight of chemical fertilizer raw materials, urea-formaldehyde coated urea (7-0-0) 0.24, monoammonium phosphate (11-47-0) 0.180, high tower nitrogen potassium fertilizer (30-0-20) 0.520.

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, specifically a synchronous slow-release special fertilizer for super hybrid rice and a preparation method thereof. Background technique [0002] Super hybrid rice has the advantages of large ears, lodging resistance, strong leaf photosynthesis, wide adaptability, and strong advantages. However, the biological yield of super hybrid rice is large, and the amount of fertilizer required is large, which will affect the efficiency of rice planting. In addition, farmers’ rice planting habits and excessive use of nitrogen fertilizer have caused problems such as nitrogen pollution. [0003] China is currently the country with the largest amount of nitrogen fertilizer in the world. Excessive nitrogen fertilization not only increases the cost of agricultural production, but also causes serious negative effects on the environment. The phenomenon that the nitrogen application level of super hybrid rice is greatly i...
