Water-soluble fertilizer, preparation method thereof and application of water-soluble fertilizer in eucalyptus topdressing

Abstract

The invention belongs to the technical field of eucalyptus fertilizers, and particularly relates to a water-soluble fertilizer as well as a preparation method and application thereof in eucalyptus topdressing. The water-soluble fertilizer provided by the invention comprises the following components in percentage by mass: 30-55% of an organic matter raw material, 20-46% of a compound nitrogen-phosphorus-potassium fertilizer, 8-20% of a medium element fertilizer, 5-12% of a trace element fertilizer and 1-3% of functional bacteria. On the basis of the characteristic that eucalyptus needs fertilizer, nitrogen, phosphorus, potassium, medium elements and trace elements are supplemented in a balanced mode; soil organic matters absorbed and consumed by the eucalyptus are supplemented through organic matter raw materials, the soil colloid content is increased, granular structure formation is promoted, the soil looseness is improved, soil fertility is prevented from being reduced, and the utilization rate of the fertilizer is increased; by adding functional bacteria, soil microorganisms are supplemented, the flora number and activity are improved, and the problem of soil microecosystem imbalance caused by eucalyptus planting is solved; the water-soluble fertilizer can be applied in various modes such as broadcast application, hole application, drip irrigation, flushing application and spraying application, so that topdressing of the eucalyptus is facilitated.

Description

technical field

[0001] The invention belongs to the technical field of eucalyptus fertilizer, and in particular relates to a water-soluble fertilizer, a preparation method thereof and an application in eucalyptus topdressing. Background technique

[0002] Eucalyptus has the characteristics of strong adaptability, rapid growth, high yield per unit area, short growth cycle, straight trunk, wide range of uses, and high economic benefits, and has been widely promoted and cultivated in many countries. As early as 2015, the area of ​​eucalyptus planted in China has reached 4.5 million ha 2 above, ranking third in the world. However, the rapid growth of eucalyptus consumes a large amount of nutrient resources in the forest soil. Behera and Sahani's study found that the conversion from natural forest to eucalyptus plantation resulted in a decrease in soil water holding capacity, organic carbon, total nitrogen, and microbial biomass and its metabolic entropy. Therefore, the large-...

[0029] The present invention also provides a preparation method of the microbial fertilizer described in the above technical solution, comprising: mixing organic raw materials, compound nitrogen, phosphorus and potassium fertilizers, medium element fertilizers, trace element fertilizers and functional bacteria to obtain water-soluble fertilizers.

[0030] The invention mixes organic raw materials, compound nitrogen, phosphorus and potassium fertilizers, medium element fertilizers, trace element fertilizers and functional bacteria to obtain water-soluble fertilizers. In the present invention, the mixing is preferably carried out under stirring conditions; the stirring time is preferably 20-30 minutes, more preferably 25 minutes. In the present invention, there is no special limitation on the stirring rate, as long as each component can be mixed uniformly.

[0031] The preparation method provided by the invention is simple and easy to operate, and is convenient for industrialize...
