Description
Technical field
The present invention relates to a kind of slow-release fertilizer field, and in particular to a kind of slow-release fertilizer of sugarcane and preparation method thereof.
Background technology
Sugarcane,（Scientific name：Saccharum officinarum）Saccharum, perennial tall and big solid draft.Root-like stock is sturdy
It is flourishing.The high 3-5 of stalk（-6）Rice.Plant extensively the south such as TaiWan, China, Fujian, Guangdong, Hainan, Guangxi, Sichuan, Yunnan torrid areas
Plant.Sugarcane is adapted to plantation in fertile soil, place sunny, summer in the winter temperature difference is big.
Sugarcane is temperate zone and tropical crops, is the raw material for manufacturing sucrose, and can refine ethanol as energy substitution product.Entirely
The world has a country more than 100 to produce sugarcane, and maximum sugarcane production state is Brazil, India and China.Contain what is enriched in sugarcane
Sugar, moisture, also containing the various vitamins very useful to human metabolism, fat, protein, organic acid, calcium, iron etc.
Material, is mainly used for refining sugar, and epidermis is generally purple and green two kinds of common colors, also there is red and brown, but more rare.
Slow-release fertilizer, so-called " release " refer to effective form that nutrient can be absorbed directly by chemical mass transfer into plant
Process (such as dissolve, hydrolyze, degraded);" sustained release " refers to that chemical substance nutrient release rate is applied much smaller than Quick-dissolving fertilizer
It is changed into the rate of release of plant effective state nutrient after soil;" controlled release " refers to make nutrients release according to setting with various regulatory mechanisms
The rule that fixed release mode (release rate and release time) absorbs nutrient with crop is consistent.Therefore, biological or chemical acts on
Under decomposable organonitrogen compound (such as ureaformaldehyde UFs) fertilizer be commonly known as slow-release fertilizer (SRFs), and to biological and chemical
The insensitive coated fertilizers of factor such as effect are commonly known as Controlled Release Fertilizer (CRFs).
Because slow-release fertilizer is with fertilizer amount reduction, utilization rate raising, using the advantages that convenient, saving of labor is safe, at present, sustained release
Fertilizer has become the direction of countries in the world fertilizer industry sustainable development.
We retrieve the fertilizer document on sugarcane as follows：
