Melt granulation nitro functional special fertilizer of tomatoes and preparation method thereof

Abstract

The invention discloses a melt granulation nitro functional special fertilizer of tomatoes and a production method of the fertilizer. The melt granulation nitro functional special fertilizer is prepared from the following raw materials in parts by weight: 260-650 parts of ammonium nitrate phosphate, 80-450 parts of monoammonium phosphate, 150-500 parts of potassium sulfate, 2-50 parts of a chelated trace element, EDTA (ethylene diamine tetraacetic acid), 0.2-1 part of compound sodium nitrophenolate and 2-20 parts of a filling agent. The preparation method comprises the steps of mixing the materials, granulating and cooling. The melt granulation nitro functional special fertilizer of tomatoes has the advantages of good water solubility, environmental friendliness, high utilization ratio, soil improvement, crop yield increase and crop quality improvement.

Description

technical field [0001] The invention relates to the technical field of special nitro fertilizer, in particular to a special fertilizer for melt granulated nitro functional tomato. Background technique [0002] Tomato, also known as tomato, is the most important crop in the family Solanaceae, and the United States, Israel, Italy and China are its main producing countries. Tomato growth requires good soil conditions and sufficient nutrient supply. Improper fertilization will have adverse effects on the growth of tomato. If there is too much nitrogen fertilizer, the carbon / nitrogen metabolism will be imbalanced, which will easily cause flower drop and fruit drop, and fruit deformity; Umbilical rot occurs, affecting yield and quality. Therefore, understanding the characteristics of tomato fertilizer requirements and supplying fertilizers in a timely and reasonable manner is an important part of tomato high-quality and high-yield. Studies have shown that the nutrients needed t...

Problems solved by technology

[0003] At present, tomato fertilization is mainly common fertilizers. Long-term use of common fertilizers will cause the soil to become compacted, the aggregate structure of the soil will be severely damaged, the quality of tomatoes will be significantly reduced, and more importantly, the ecological environment will be seriously damaged; The absorption law is consistent, and the fertilizer utilization rate is low; farmers often use experience fertilization as the main method of fertilization, which has high costs, and leads to damage to the soil structure and environment, and the decline in crop resistance
