Abstract
The present invention discloses a kind of corn durable composite fertilizer, the corn durable composite fertilizer is made up of fertiliser granulates with the hydrophobic permeable membrane for being coated on fertiliser granulates surface, wherein, the fertiliser granulates are made up of nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, flyash and adhesive, and nitrogenous fertilizer, phosphate fertilizer in the fertiliser granulates, potash fertilizer press N P2O5‑K2O=24 8 10 is prepared.Compared with existing durable composite fertilizer, slow release effect of the invention more preferably, is used more suitable for corn.
Description
Technical field
The invention belongs to composite fertilizer field, and in particular to a kind of corn durable composite fertilizer.
Background technology
Chemical fertilizer is one of important means that modern agriculture improves crop yield.Common N,P,K fertilizers were applying fertilizer
There is a problem of being lost in journey, such as nitrogen manure is easily decomposed, phosphate fertilizer is easily adsorbed by basic soil to be fixed, for extension fertilizer efficiency reaches
The effect of nitrogenous fertilizer long-acting controlled release, have developed the additives such as nitrobacteria inhibitor, urease inhibitorses, but add using this kind of in succession
Plus the composition of agent is higher.
The content of the invention
The technical problem to be solved in the present invention is to overcome existing defect, there is provided a kind of corn durable composite fertilizer.
In order to solve the above-mentioned technical problem, the invention provides following technical scheme：
A kind of corn durable composite fertilizer, it is made up of fertiliser granulates with the hydrophobic permeable membrane for being coated on fertiliser granulates surface, its
In, the fertiliser granulates are made up of nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, flyash and adhesive, nitrogenous fertilizer, phosphate fertilizer in the fertiliser granulates,
Potash fertilizer presses N-P2O5-K2O=24-8-10 is prepared.
Preferably, the nitrogenous fertilizer is urea, ammonium chloride, ammonium sulfate or ammonium nitrate.
Preferably, described phosphate fertilizer is one-lime phosphate, calcium superphosphate, MAP or Diammonium phosphate (DAP).
Preferably, the potash fertilizer is potassium chloride, potassium sulfate, monopotassium phosphate or potassium nitrate.
Preferably, described adhesive is polyvinyl alcohol.
Preferably, the consumption of the polyvinyl alcohol is 0.5~2wt% of fertiliser granulates weight.
The method for preparing above-mentioned corn durable composite fertilizer, it is characterised in that comprise the following steps：
（1）Nitrogenous fertilizer, phosphate fertilizer, potash fertilizer and flyash are mixed and heated to 300~400 DEG C, stirring is cooled down after 0.5-1 hours, then
Adhesive is added, granulation is made the particle of 2-4mm, dries, and obtains fertiliser granulates；
（2）After fertiliser granulates are preheated into 90-110 DEG C in addition coating machine, then to addition organic siliconresin in coating machine to fertilizer
Material particle carries out coating, and the consumption of organic siliconresin is the 5~10% of fertiliser granulates weight.
The present invention determines N-P according to the nutritional need of corn growth2O5-K2O=24-8-10.Compared with general filler, this hair
The porous network structure that bright utilization flyash inside is present, at high temperature mixes nitrogenous fertilizer, phosphate fertilizer, potash fertilizer with flyash, so that
Increase the crystallized ability to nutrient.Organic siliconresin can form one layer of holding film of hydrophobic, air-permeability on the surface of particle, can control
The combination speed of fertiliser granulates processed and moisture content, plays the rate of release of further conditioned fertilizer product.
