Super rice special fertilizer and preparation method thereof

Abstract

The invention discloses a super rice special fertilizer and a preparation method thereof. The special fertilizer comprises the following components in percentage by weight: 12.5 percent of nitrogen, 6.0 percent of phosphorus, 10.0 percent of potassium and 20.0 percent of biological organic fertilizer. The super rice special fertilizer can be used for obviously reducing the fertilizer applying quantity to rice, reducing pests and the discharge of farmland water pollutants, improving the fertilizer utilization rate, increasing the fertility of soil, maintaining the equal output or the increase production of the rice output and obviously improving the economic benefit of rice planting. Through using the super rice special fertilizer for the super ric and matching a concentrative fertilizing technology, the application frequency is effectively reduced, the labor cost can be saved, the content of organic matters in the soil can be increased, and the sustainable development of the rice field ecological system can be realized.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to the field of mixed fertilizers in agricultural production. Background technique [0002] For a long time, rice fertilization has been mainly based on nitrogen fertilizer, with less application of phosphorus and potassium fertilizers, and less application of organic fertilizers. Long-term application of a single fertilizer not only causes an imbalance in nutrient supply and cannot meet the needs of various nutrients for rice growth and development, but also leads to a continuous increase in fertilizer application and a gradual decline in utilization rate, resulting in a serious lack of soil organic matter. Soil compaction, rice yield reduction and rice quality deterioration. In addition, the excessive application of nitrogen fertilizers is likely to cause a large number of pests and diseases, increase production costs, increase greenhouse gas emissions and increase nitrogen...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a special fertilizer for super rice according to the problems existing in existing rice fertilizers that mainly use nitrogen fertilizer, resulting in a single fertilizer, unbalanced nutrient supply, unable to meet the needs of rice for nutrients, and deteriorating the soil environment. The fertilizer mixes nitrogen fertilizer, potassium fertilizer and phosphorus fertilizer with bio-organic fertilizer, which solves the problem of single fertilizer, can meet the needs of rice growth and development for various nutrients, and increase soil fertility
