Abstract

The invention discloses long-acting multi-element leaf microelement fertilizer comprising a microelement fertilizer raw material, an auxiliary material, a synergist, a slow-release binding material and a natural high-molecular material coated material. The microelement fertilizer, the slow-release material and a leaf binding agent are combined, and therefore after being sprayed to leaves, the microelement fertilizer is protected by the slow-release agent and is not prone to oxidation and ineffectiveness; the binding agent increases the rain wash resistance and the wind and sunshine denudation resistance of the microelement fertilizer, the adhesive force of the microelement fertilizer to the leaves is increased, the time for the microelement fertilizer to stay on the leaves is prolonged, and the absorption rate of the fertilizer is increased. The invention further provides a preparation method of the long-acting multi-element leaf microelement fertilizer.

Description

technical field [0001] The invention relates to a long-acting multi-element foliage micro-fertilizer, belongs to the technical field of fertilizer production, and also relates to a preparation method of the micro-fertilizer. Background technique [0002] At present, there are two types of micro-fertilizers sprayed by farmers. One category is spraying after dilution with one or more common micro-fertilizers; one is the task of spraying after dilution with one or more slow-release micro-fertilizers. Although the second type uses slow-release micro-fertilizers, when it is sprayed on the leaves of plants, it does not resist the erosion of rainwater and the erosion of wind and sun, and it is also easy to be eroded on the ground. thereby losing its effect. Contents of the invention [0003] In view of the above-mentioned deficiencies, the present invention provides a long-acting multi-element foliage micro-fertilizer, which combines micro-fertilizer, slow-release material, and...
