Description
Technical field
The present invention relates to a kind of Water-retaining slow-release fertilizer and preparation method thereof, belong to chemical fertilizer field.
Background technology
The problems such as environmental pollution and the wasting of resources that chemical fertilizer utilization rate is low to be caused is restrict China's agricultural development two
Individual subject matter.Since 1960s, chemical fertilizer utilization ratio is low and pollution by chemical fertilizer is asked to solve for slow release fertilizer production technology
Topic opens new thinking and more effective approach.In recent years, by water-loss reducer and slow release fertilizer in material and functionally compound one
Body, research and development can slowly be sustained the Water-retaining slow-release fertilizer put with water retaining function, nutrient, important for the outstanding tool of agricultural
Meaning, Water-retaining slow-release fertilizer has become an important field of research.
Water-retaining slow-release fertilizer is different from Fertilizer combination mode according to water-loss reducer, is generally divided into absorbing process type, blending technique
Four kinds of type, coating process type and chemical technology type.Absorbing process type：Refer to water-loss reducer being placed in certain density water soluble fertilizer
Soaked in solution, absorbent solution formation colloidal sol or the hydrosol can be made into absorbent-type Water-retaining slow-release fertilizer after dry, crushing.Mix
Mixed craft type：It is that Water-retaining slow-release fertilizer hybrid particles are made by comminutor after mixing water-loss reducer and common fertilizer.Coating work
Skill type：Refer to water-loss reducer by either physically or chemically wrapping up the coating process of fertiliser granulates surface.Chemical technology type：It is
Refer to and fertilizer nutrient group is bonded in the macromolecular skeleton structure of water-loss reducer by chemical reaction, improve the slow release effect of nutrient.
But these methods due to during physical crushing the network structure of water-loss reducer destroyed, the degree of cross linking reduction, make water-loss reducer
Water solubility increase, causes fertilizer water absorbent rate and soil water-retaining rate to reduce, and sustained release performance is poor.
It would therefore be highly desirable to which developing a kind of water absorbent rate and the good Water-retaining slow-release fertilizer of soil water-retaining rate height, sustained release performance has
Necessary meaning.
The content of the invention
The technical problems to be solved by the invention：For traditional Water-retaining slow-release fertilizer water absorbent rate and soil water-retaining rate compared with
It is low, and sustained release performance it is poor the drawbacks of there is provided a kind of Water-retaining slow-release fertilizer and preparation method thereof.
In order to solve the above technical problems, the present invention is using technical scheme as described below：
A kind of Water-retaining slow-release fertilizer, includes the component of following parts by weight：120~150 parts of water, 60~80 parts of moisture retaining groundmass, 40
