Technical field
The present invention relates to a kind of eucalyptus organic-inorganic compound fertilizer specials and preparation method thereof, belong to technical field of fertilizers.
Background technology
Eucalyptus (Eucalyptus robusta Smith) is also known as You Jiali trees, is the general designation of Myrtaceae eucalyptus plant.
Evergreen high megaphanerophyte, about more than 600 plant.It introduced a fine variety in 19th century to all over the world mainly in Australia continent, by 2012, has in source area
There are cultivation in 96 countries.The plantation of China eucalyptus has more than 100 years history, and nearly more than ten years eucalyptus is planted in me
State south is quickly grown.Currently, eucalyptus is because its is adaptable, growth is rapid, growth cycle is short, biomass is big, trunk is logical
Directly, the features such as widely used, high financial profit, is classified as the preferred seeds of National Industrial raw material forest afforestation by China.
In the management of eucalyptus high yield and quality cultivation, fertilising is one of the measure of most effective fruit.Eucalyptus rapidly absorb include nitrogen,
The main nutrient elements such as phosphorus, potassium, calcium, magnesium, copper, manganese, zinc, boron, cause soil fertility dramatic decrease, soil hardening, acidification, organic
Matter lacks.And China's Eucalypt plantation soil fertility is poor, N, P, K and the content of organic matter are low, middle microelement deficiencies.
Some eucalyptus organic-inorganic compound fertilizer special material have been noted that the addition of middle trace element currently on the market, still
But do not consider absorption efficiency of the eucalyptus to nutriment, be often not achieved high yield, high yield desired effect.Therefore it applies fertilizer in eucalyptus
In the process, the fertilizer that addition meets trace element, organic matter and nitrogen, phosphorus, potassium rational proportion needed for Eucalyptus is to influence eucalyptus
The key of the quality and yield of tree.
In consideration of it, it is necessary to provide a kind of new eucalyptus organic-inorganic compound fertilizer specials, to solve above-mentioned deficiency.
