Abstract
The invention discloses slow-release fertilizer. The slow-release fertilizer comprises components in parts by weight as follows: 10-95 parts of plant nutrients, 1-8 parts of a lubricant and 0.1-8 parts of a slow-release agent. The invention further discloses a preparation method of the slow-release fertilizer. The method comprises steps as follows: according to the formula, weighing all the components; sequentially crushing and evenly mixing the components to obtain the slow-release fertilizer. After the slow-release fertilizer obtained with the method is applied to soil or matrix, fertilizer nutrients in the slow-release fertilizer are gradually dissolved and released for plants to absorb and utilize during watering each time, the fertilizer releases fertilizer nutrients continuously, the utilization rate of the fertilizer is high, and the application range is wide.
Description
Technical field
The invention belongs to slow release fertilizer field, specifically, is about a kind of slow release fertilizer and preparation method thereof.
Background technology
Fertilizer slow release sheet is by chemistry or Physical is made, can delay nutrient release rate, the fertilizer that can utilize for plant constant absorption, the nutrient compound contained in its fertilizer in soil or cultivation matrix release rate slowly or release rate can obtain control to a certain extent, make the nutrient in fertilizer can meet the different demands of each growth phase of crop.
Fertilizer slow release sheet common at present mainly contains following three kinds:
1, the compound of water is insoluble in, as secondary calcium phosphate.The manufacturing of this series products is more difficult, and the nutrient only having Activities of Some Plants required can produce the compound being insoluble in water, and this series products easily lumps, and uses inconvenience, and long-time use easily causes soil compaction, the spoiled soil eubiosis.
2, coating or coated fertilizer, as sulfur-coated urea, resin coated fertilizers.The problem that coating or coated fertilizer face at present is exactly that manufacturing cost is high, coating or coated material expensive, after being manured into soil, some coated fertilizer be difficult to degraded, also can cause certain environmental pollution, the physico-chemical property of spoiled soil.
3, carrier fertilizer slow releasing tablet, namely fertilizer nutrient and natural or synthetic are by the fertilizer of physics or chemical reaction.This type of production technique for fertilizer is complicated, and complicated reaction easily occurs various material for a long time, wayward, in transport, use procedure, there is potential safety hazard.
These products are not suitable with the demand of Modern Family's gardening, and they more need easy to use, once complete fertilising, dispenser, the convenient Gardening Materials stored.
Summary of the invention
The object of the invention is to provide a kind of slow release fertilizer of sustainable, high utilization rate, to solve the requirement that existing slow release fertilizer cannot reach environmental protection, and simultaneously again can not the problem of Sustainable and highly-efficient use.Another object of the present invention is the preparation method providing slow release fertilizer.
For achieving the above object, the present invention is by the following technical solutions:
A kind of slow release fertilizer, comprises following component and weight part:
