Description

A kind of efficient magnetic sustained-controll-release fertiliser that can promote Wheat Photosynthesis effect and its preparation Method

Technical field

The present invention relates to magnetically slow releasing technical field of fertilizers, more particularly to a kind of efficient magnetic that Wheat Photosynthesis can be promoted to act on Sustained-controll-release fertiliser and preparation method thereof.

Background technology

At present release-controlled coated fertilizer complies with the call in epoch and the demand in market, towards it is new, environmentally friendly, efficient, cheap, can hold Continuous direction is developed, and 12 planning of country is as one of emphasis direction therefore individual big high both at home and abroad using new and effective slow-release fertilizer Effect and enterprise are all in actively research and development slow-release fertilizer, the big bottleneck of two for currently encountering：One is that production cost is high, and two is sustained release film material Slow release and biodegradable properties it is poor, the overall utilization rate of fertilizer is less than 50%, it is often more important that the slow-release fertilizer in market Slow release effect is not good, has focused largely on sustained release performance, also more rare for the Controlled Release Fertilizer required with higher sustained release.

Over nearly twenty or thirty year, magnetic fertilizer has tremendous development, but for current industry receives still falls within new fertilizer Material, because it is seldom occurring on the market.Magnetic fertilizer is related to fertilizer, bio-fertilizer, Chemical Mixed Fertilizer, and its distinctive magnetic characteristic can be bright Aobvious ground has superiority relative to the fertilizer for not having magnetic characteristic, and it can significantly improve crops proterties, improve the yield and quality. But as magnetic fertilizer generally carries out magnetization treatment and later stage from device for magnetizing and treating in process, fail effectively to push away Extensively.

Nano fertilizer is new things, is ground with reference to nanometer technology, medical microcapsules technology and chemical industry micro-emulsion technology The new and high technology sent out, including nanostructured feed, 3 big class of nano-magnetic fertilizer and nano biological compound fertilizer, these Nano fertilizers Expect to make fertilizer integrally with magnetic effect because of the nanometer small-size effect of itself or the material for adopting, so that nutrient is easier It is absorbed by plants, is conducive to plant growth, but, due to the restriction of cost, do not promoted on a large scale.

How more preferable slow release effect is prepared by magnetisable material and nano fertilizer technology, more inexpensive concentrated fertilizer has Significance.
