Abstract
The invention discloses a using method of a humic acid fertilizer. The method comprises the steps of firstly, enabling sodium humate to be dispersed into acrylic resin particles; and then, dipping the acrylic resin particles into water, and embedding the acrylic resin particles into the root of a plant after the particles are saturated by absorbing water. After the using method is used, the sodium humate is prevented from running off due to being more rapidly washing away by rainwater; the using method also has a certain water retention effect.
Description
Technical field
The present invention relates to a kind of using method of humic acid fertilizer.
Background technology
Humic acids is that animals and plants remains transform the macromolecule organic matter produced through microbial decomposition, it has promotion soil aggregate and is formed, strengthen soil permeability, fertilizer-preserving ability, to plant-growth, there is effect of stimulation, increasing plant drought, cold-resistant, disease resistance ability, is a kind of desirable Eco-fertilizer.Use more one to be Sodium salts humic acids in humic acid fertilizer, but Sodium salts humic acids is very easily water-soluble, in use, serious with rain water runoff.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of using method of humic acid fertilizer.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A using method for humic acid fertilizer, comprises and being first dispersed in acrylic resin particle body by Sodium salts humic acids, then acrylic resin particle is immersed water reach water suction saturated after be embedded in plant root.
By following method, Sodium salts humic acids is dispersed in acrylic resin particle body:
(1) Acrylic Acid Monomer is mixed with water, then add linking agent and initiator successively, at 75-85 DEG C, react 1-1.5 hour, obtain acrylate prepolymer;
(2) after acrylate prepolymer regulates pH to 6-6.5 with alkali, then add Sodium salts humic acids, stir slaking, obtain gel;
(3) gel obtains through granulation, drying.
Further, the mass ratio of described Sodium salts humic acids and acrylic resin is (1-5): 1.
Further, the linking agent that existing acrylic resin polyreaction can be adopted conventional and initiator, described linking agent is preferably tetramethylolmethane three allyl ether, and initiator is preferably Potassium Persulphate.
Further, described alkali is sodium hydroxide or potassium hydroxide.
Sodium salts humic acids is dispersed in acrylic resin particle body by the present invention, utilizes the self-strength of gel to prevent Sodium salts humic acids with rain water runoff.
Embodiment
Below in conjunction with preferred embodiment, the present invention will be described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
Embodiment 1
200g Acrylic Acid Monomer is joined in the beaker of 1L, add 500g water successively again, 1.5g linking agent tetramethylolmethane three allyl ether and 0.2g Potassium Persulphate, be warming up to 80 DEG C, react after 1 hour, obtain performed polymer, after performed polymer regulates pH to 6.5 with sodium hydroxide, then add 300g Sodium salts humic acids, stir slaking 3 hours, obtain gel, granulation, drying obtains humic acid fertilizer.
Embodiment 2
200g Acrylic Acid Monomer is joined in the beaker of 1L, add 500g water successively again, 1.0g linking agent tetramethylolmethane three allyl ether and 0.24g Potassium Persulphate, be warming up to 75 DEG C, react after 1.5 hours, obtain performed polymer, after performed polymer regulates pH to 6 with sodium hydroxide, then add 500g Sodium salts humic acids, stir slaking 5 hours, obtain gel, granulation, drying obtains humic acid fertilizer.
Embodiment 3
100g Acrylic Acid Monomer is joined in the beaker of 1L, add 300g water successively again, 0.3g linking agent tetramethylolmethane three allyl ether and 0.18g Potassium Persulphate, be warming up to 85 DEG C, react after 1 hour, obtain performed polymer, after performed polymer regulates pH to 6.5 with sodium hydroxide, then add 500g Sodium salts humic acids, stir slaking 3 hours, obtain gel, granulation, drying obtains humic acid fertilizer.
Using method, is immersed in the water humic acid fertilizer, wait reach water suction saturated after, by humic acid fertilizer take out, be embedded in plant root.The water regain of humic acid fertilizer can reach 250-350g/g, and gel-strength reaches 170-200g/cm
2, after water suction, because acrylic resin has good intensity and water-retentivity, Sodium salts humic acids can be separated out lentamente in acrylic resin body, thus avoids that Sodium salts humic acids is too fast is washed away loss by rainwater, there is again certain Water-saving effect simultaneously.Acrylic gel has good biodegradability properties, can not pollute ecology.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (5)
