Production method of special fertilizer for eucalyptus

Abstract

The invention discloses a production method of a special fertilizer for eucalyptus, which belongs to the field of fertilizer preparation. The eucalyptus fertilizer produced by the invention can be provided according to the change of different fertilizer elements required by eucalyptus throughout the year. During January-April, nitrogen is mainly provided , rapid and dense growth leaves. From May to September, it mainly provides phosphorus to make the trunk grow rapidly and increase the sap of the trunk of the eucalyptus. In the later winter, it provides more potassium fertilizer to improve the transportation of water, so that the nutrient transportation of the tree is the same The tree is active, the growth of the tree is not limited by the season, and the growth is faster and better.

Description

technical field [0001] The invention relates to the field of fertilizer preparation, in particular to a production method of special eucalyptus fertilizer. Background technique [0002] Eucalyptus grows fast and has excellent materials. It is a short-cycle economic tree that is currently popularized and planted in China. Its wood is widely used in papermaking and fiber board processing. However, the demand for nutrients in the growth process of eucalyptus is greater than that of other tree species, so sufficient fertilizer must be applied to make eucalyptus grow normally. [0003] For this reason, some people have begun to study eucalyptus fertilizer at present. For example, Chinese patent application 03139716 discloses a trace element fertilizer, which contains two or more of B, Cu, Zn, Mn, Fe and Mo elements, and is used to prevent and treat eucalyptus deficiency diseases. [0004] At present, more are compound fertilizers composed of inorganic fertilizers and trace elem...

Problems solved by technology

For example, Chinese patent 96105688 discloses a coating fertilizer, wherein the composition of the soil layer is except 0.1~50 parts of animal glue, mainly soluble inorganic salts, such as 1~180 parts of solubilizer (its main components are ammonium sulfate, ammonium nitrate and other inorganic salts) and 0.1 to 200 parts of plant nutrient element compounds (mainly iron and zinc sulfates), resulting in a large amount of soluble inorganic salts in the animal glue-wrapped coating, which dissolve quickly after contact with water and make the fertilizer particles porous shape or disintegration, the actual sustained release (controlled release) ability is very limited

As another example, Chinese patent CN202072642U discloses a special slow-release compound fertilizer for eucalyptus that is included in an organic coating layer, but the main components of the organic coating layer are polyethylene and paraffin, which are difficult to degrade and cannot effectively release the internal fertilizer, even causing polyethylene plastic white pollution

[0007] Existing eucalyptus fertilizers dissolve too quickly, and fertilization once a year cannot satisfy the growth of eucalyptus trees for a year. Often, after half a year, the growth of eucalyptus trees will be slower. If fertilizers are applied twice a year, the labor cost will be greatly increased. At the same time as a waste of fertilizers, etc.
