Stable fertilizer additive

Abstract

The invention discloses a stable fertilizer additive which comprises the following formula ingredients in parts by mass: 40-60 parts of distillers' grains, 1-3 parts of a cadmium metal antagonist, 10-12 parts of disodium inosinate, 10-20 parts of montmorillonite, 5-15 parts of phosphorus nitrate granules, 5-7 parts of hydroquinone, 1-3 parts of a urease inhibitor, 15-25 parts of ammonium carbonate fertilizers and 1-3 parts of a PH regulator. The stable fertilizer additive has the advantages that the cost of the production raw materials is low, the production process is simple, convenient and feasible, and the materials are obtained conveniently, and therefore, the stable fertilizer additive is a new trend of fertilizer development.

Description

technical field [0001] The invention relates to the field of additives, in particular to a stabilized fertilizer additive. Background technique [0002] With the increase of population, decrease of arable land, and the improvement of people's living standards, agriculture is required to continuously increase production and quality. Fertilizer plays an important role in agricultural production, accounting for more than 30% of the weight of many production-increasing factors. China is a big country in the production and use of chemical fertilizers. Its output and usage rank first in the world, but the product quality needs to be further improved. The main problem is that the fertilizer utilization rate is low, the fertilizer effect period is short and the function is single, and the nitrogen fertilizer effect period is only 30-50 days. However, the general crops need fertilizer for 90-120 days, and the fertilizer effect period is not coordinated with the crops' fertilizer need...

Problems solved by technology

China is a big country in the production and use of chemical fertilizers. Its output and usage rank first in the world, but the product quality needs to be further improved. The main problem is that the fertilizer utilization rate is low, the fertilizer effect period is short and the function is single, and the nitrogen fertilizer effect period is only 30-50 days. However, the general crops need fertilizer for 90-120 days, and the fertilizer effect period is not coordinated with the crops' fertilizer need period. In agricultural production, only multiple fertilization can be used to solve the problem. The operation of top dressing is time-consuming and laborious, which is extremely unsuitable for modern agriculture. 30-40%. In addition, 60-70% is volatilized and enters the atmosphere and water, causing serious waste and environmental pollution. The utilization rate of phosphate fertilizers becomes low, and the utilization rate in the current season is only 20-25%. Prolonging fertilizer efficiency is beneficial to agriculture and can reach One-time fertilization and exempting the topdressing process have the comprehensive benefits of increasing production, saving fertilizer and labor, and improving the utilization rate is not only of great significance to agriculture, especially to the entire national economy, but also has social and ecological benefits of saving resources and improving the environment. Therefore, since 2005, the state has increased the requirements in the No. 1 document year by year, and promoted the application of slow and controlled release fertilizers including stable fertilizers as soon as possible.
