Abstract
The invention relates to a controlled release potash fertilizer and a preparation method thereof, and raw materials comprise granular potassium sulfate or potassium chloride, humic acid, and bentonites. The preparation method comprises the following steps: well mixing crushed humic acid and bentonites proportionally, preparing the raw materials according to a weight part ratio (granular potassium sulfate or potassium chloride:humic acid:bentonite=60-70:20-25:10-15), coating the surface of granular potassium sulfate or potassium chloride with the mixture of humic acid and bentonites by using an adhesive on a disc granulator. The controlled release potash fertilizer rich in organic matter comprises 30%-40% of potassium elements, 30%-40% of humic acid, and 5%-8% of bentonites, has a high organic matter content, can effectively realize slow and controlled release of the potash fertilizer, thus can reduce the application amount of the potash fertilizer and reduce plantation cost. When the humic acid slow-release potash fertilizer of the invention is applied to crops, not only the yield is increased, but also the quality is improved.
Description
Technical field
The present invention relates to a kind of controlled-release fertilizer and preparation method thereof.
Background technology
At present, in agriculture prodn, because of application of potash fertilizer few or improper; Caused the decline of crops quality; Not fragrant like the rice wheat, melon and fruit is sweetless lopsided with outward appearance, and this mainly is the unbalance result of corps nutrient; Be that common potash fertilizer can not satisfy the demand of farm crop intermediary and later stages to potassium element, be prone to cause the farm crop later stage to take off fertilizer.In order to solve " high yield not high-quality, product price is low " problem, effective means is to use the potash fertilizer with slow release that contains humic acid, but does not still have this type of fertilizer on the agricultural materials market at present.
Organic controlled release potash fertilizer utilizes physical property tackiness agent packing technology to make granular potassium sulfate or Repone K surface parcel one deck contain the film of humic acid; This layer film not only played the control slow release action of potash fertilizer but also with the humic acid rational Match in potash fertilizer; In the process that granular potassium sulfate or Repone K are slowly discharged in soil humic acid also is applied in the soil, and the release rate of this kind product and crop regulation of fertilizer requirement are identical basically, nutrient supply is balanced sufficient; Release period can reach 100 days continuously; This effect can make the crop intermediary and later stages not take off fertilizer, and the time of infertility is effective, and potassium utilization rate can improve more than 80%.
Summary of the invention
First purpose of the present invention provides a kind of controlled-release fertilizer that contains humic acid that wraps up form, and second purpose of the present invention provides this humic acid control-releasing potash fertilizer preparation method.
For first purpose that realizes inventing, the humic acid control-releasing potash fertilizer that is provided, raw material comprises: particulate state vitriolate of tartar or Repone K, humic acid, wilkinite.In proportion with the humic acid and the even blending of wilkinite of pulverizing; According to parts by weight ratio (granular potassium sulfate or Repone K: humic acid: wilkinite=60～70: 20～25: ratio 10～15); After getting the raw materials ready successively, on granulating disc, will contain humic acid and bentonitic blend powder wrapped makes at granular potassium sulfate or Repone K surface with tackiness agent.
For increasing the slow release effect of humic acid slow release potash fertilizer, also including parcel tackiness agent (through CMC 99.5, xylogen, the vegetables oil of hydrolysis) weight part in the proportioning raw materials of the slow-release potassium fertilizer that is provided is 3.
This controlled-release fertilizer that is rich in organic matter; Contain 30%～40% potassium element, 30%～40% humic acid, 5%～8% wilkinite, this potash fertilizer organic content is high, and can effectively delay the release of controlling potash fertilizer; Thereby can reduce the potash fertilizer amount of application, reduce planting cost.Farm crop are used humic acid slow release potash fertilizer of the present invention, not only can improve output, and can promote its quality.
For second purpose that realizes inventing, the preparation method of the humic acid control-releasing potash fertilizer that is provided comprises the steps: successively
A, pulverizing: respectively humic acid, wilkinite granularity are crushed to 60 orders～80 orders;
B, blending: humic acid and wilkinite are stirred according to weight ratio;
C, mixed adhesive: according to ratio of weight and number is silica gel: CMC 99.5, use the vegetables oil uniform mixing after the xylogen hydrolysis, and form tackiness agent;
D, enwrapped granule: granular potassium sulfate or Repone K are sent in the granulating disc that has the fluid jetting head rotation, behind even spray adhesive on granular potassium sulfate or the Repone K surface, added the blend of humic acids and bentonite in powder.After this process repeats 2-3 time, make the granularity of material in the dish finally become 2.5mm～3.5mm particle, skin is the humic acid integument of black, has formed to contain the potash fertilizer that organic matter has the slowly-releasing effect;
E, oven dry: the particle behind the coating gets into dehumidification system through transfer roller, and hot blast temperature is warming up to 140 ℃ of half a hour one by one by 100 ℃, both can obtain the particle slow release potash fertilizer products of water ratio below 5%.
Granular controlled release potash fertilizer provided by the present invention has the effect of raising the output; The content that not only contains needed available potassium element of crop growth but also humic acid is up to 30%～40%; Simultaneously because of having slow-release function, having solved the crop growth middle and later periods takes off the potassium element that fertilizer causes and supplies inadequate problem.The utilization ratio of potash fertilizer is increased substantially, can reduce dose effectively, reduced planting cost, and the protection edatope.
Use controlled-release fertilizer provided by the present invention, not only can improve the output of farm crop, and can promote its quality.Experiment shows, under the equal conditions: wheat increase yield 10%～15%, increasing production of rice 10%～25%, peanut yield increasing 10%～35%, corn yield increasing 15%～19%, cotton raising the output 10%～15%, melon and fruit is fragrant and sweet and stature is even.
