Abstract

The invention provides a slow-release high-yield crop fertilizer which comprises the ingredients of nitrogen, phosphate and kalium, wherein the nitrogen comprises large-particle slow-release urea and small-particle slow-release urea, the phosphate comprises diammonium phosphate and monoammonium phosphate, and the kalium comprises imported potassium chloride and imported potassium sulfate. The invention mainly solves the problems that the prior fertilizer has insufficient nutrients, low content and unreasonable nitrogen-phosphate-potassium proportion and can not be singly fertilized or de-fertilized, also solves the peasant fertilizer-selecting difficulty problem and the great before-sowing fertilizer-mixing labor expense problem generally existed in the prior production, omits additional fertilizer for planting corn and rice and has the advantages of fertilizer effect improvement, final crop yield improvement, and the like.

Description

(1) Technical field [0001] The invention relates to the technical field of crop fertilizers, in particular to a long-acting and high-yield crop fertilizer. (2) Background technology [0002] 1. Elementary element and two-element fertilizers have insufficient nutrients and cannot be applied alone. Such as urea and diammonium phosphate, although they are high-quality fertilizers, their nutrients are not comprehensive, and they cannot be used alone in production. [0003] 2. Compound fertilizer, the nutrient content is mainly concentrated between 30% and 45%, and the nutrient content is low. Although the nutrient is comprehensive, it has strong quick-acting effect and short fertilizer effect. If it is applied alone, the defertilization will be serious in the later stage, resulting in a significant reduction in crop production. [0004] 3. There are more than a hundred kinds of fertilizers on the market, but there is no special fertilizer for crops that can be applied alone. Wh...
