Special fertilizer for eucalyptus and preparation method of special fertilizer

Abstract

The invention discloses a special fertilizer for eucalyptus and a preparation method of the special fertilizer. The fertilizer comprises the following components in part by weight: 65-85 parts of a large element basic fertilizer, 1-5 parts of medium and trace element fertilizers, 2-4 parts of humic acid, 0.1-0.5 part of microbial bacteria, 0.1-0.5 parts of a sustained release synergist, 1-4 partsof organic carbon and 10-20 parts of a filler. The special fertilizer for the eucalyptus, disclosed by the invention, has complete element compositions and can prevent an element deficiency symptom inthe growth process of the eucalyptus, thereby enhancing the resistance of the eucalyptus to an acuminate disease, reducing miscellaneous branches and enhancing the tree potential and the volume accumulation; in cooperation with the sustained release synergist, the fertilizer efficiency can be increased, and the times for applying the fertilizer by growers is reduced, so that the labor cost is reduced; finally, in match with more highly-active organic matters, carbon sources can be supplemented for the eucalyptus; while the eucalyptus photosynthesis is improved, and the volume accumulation isincreased, the carbon sources can also be taken as nutrient sources for microorganisms, so that the proliferation of the microorganisms is promoted, the soil environment is improved, and the disease and stress resistance of the eucalyptus is enhanced; and the effect on the cultivation of the eucalyptus is better.

Description

technical field [0001] The invention relates to the technical field of special fertilizers, in particular to a special fertilizer for eucalyptus and a preparation method thereof. Background technique [0002] Eucalyptus is the general name of Eucalyptus in Myrtaceae. There are more than 600 species of evergreen plants. It has the characteristics of strong adaptability, rapid growth, high yield, short growth cycle, straight trunk, wide range of uses, and high economic benefits. Cultivation is widely promoted in many countries. In large-scale artificial cultivation, fertilizer is an important factor affecting its growth and plant properties. There have been many researches on the fertilizer efficiency of different fertilizers for eucalyptus in my country. The results show that the types and contents of nutrients, chemical properties, and production processes of different fertilizers are not the same. After being applied to eucalyptus, the fertilizer response of eucalyptus is ...

Problems solved by technology

In large-scale cultivation, these fertilizers are quick-acting fertilizers, which are not conducive to long-term absorption of crops, and repeated fertilization of cultivated species will cause soil retention capacity to decrease, organic matter content in the soil will decrease, and the lack of trace elements will become more and more serious. Forest land will become barren and fertilizer will be lost. High efficiency, low nutrient utilization efficiency, and easy to cause environmental pollution
