Description
Technical field
The present invention relates to a kind of moisture retaining groundmass technical field, particularly one easy degradation particles type moisture retaining groundmass and preparation method thereof.
Background technology
China is a large agricultural country, and agricultural water accounts for more than 80% of China's total water consumption, and the shortage of water resources is the first cause of restriction China's agricultural development.Therefore improve the utilising efficiency of agricultural water resources, implement the important channel that saving water, resisting drought technology is China's agricultural sustainable development.Wherein moisture retaining groundmass is as a kind of Water-saving agricultural technology, and its raw material sources are extensive, superior performance, and cost simple to operate is on the low side simultaneously, has no side effect, have vast potential for future development to environment.But the embody rule of moisture retaining groundmass is on the low side in the market, the effect of simultaneously mostly moisture retaining groundmass only tool water saving soil moisture conservation, cannot meet the multiple demand of plantation.For this reason, current inventor provides a kind of granule type moisture retaining groundmass and preparation method thereof, the raw material used is mostly cheap and easy to get, wherein moisture retaining groundmass inside not only has water sorption, simultaneously containing the nutritive element needed for plant-growth, after moisture is absorbed and is entered moisture retaining groundmass core by outer field hole or gap, contact with the inside nutrient that absorbs water, be partially dissolved in water, form nutritive medium and be kept at moisture retaining groundmass inside, absorb for root system of plant, not only save agricultural water, reduce chemical fertilizer to drop into simultaneously, improvement soil, growth for plant provides the guarantee on technology and material.
Summary of the invention
The present invention compensate for the deficiencies in the prior art, provides a kind of easily degradation particles type moisture retaining groundmass and preparation method thereof.
Technical scheme of the present invention is as follows:
Fertilizer of the present invention is made up of the raw material of following weight part: W-Gum 55-75, acrylamide 50-60, natural pond slag 12-15, ammonium persulphate 0.2-0.4, N, N'-methylene-bisacrylamide 0.4-0.5, earthworm excrement 18-22, vinylformic acid 60-70, vinegar grain 8-10, EM microbial inoculum 2-3;
The concrete steps of the preparation of described moisture retaining groundmass are as follows:
(1) W-Gum is placed in 1 times to the water of its quality, boils heating 30-40 minute, for subsequent use;
(2) after step 1 gained material is cooled to room temperature, vinylformic acid, acrylamide is added, sodium hydroxide neutralization is added after stirring, add ammonium persulphate, N, N'-methylene-bisacrylamide again, reaction system is heated to 80-100 DEG C of reaction 2-3 hour;
(3) step 2 gained material is dried at 100-110 DEG C, be placed in after pulverizer is pulverized and cross 60 mesh sieves, obtain powder for subsequent use;
(4) earthworm excrement, vinegar grain, the mixing of natural pond slag, EM microbial inoculum and leftover materials are placed in fermentation vat, add a small amount of water, keep fermentation heap water content at 40-45%, sealing and fermenting 2-3 week, gained tunning is dried granulation after pulverizing, grain diameter controls at 1.0-1.5mm, more moistening crude to particle surface to particle surface spraying high temperature atomized water steam, and step 3 gained powder is sprayed on particle surface;
(5) dry step 4 gained particle to constant weight, packaging is preserved, and obtains granule type moisture retaining groundmass of the present invention.
Boiling heat-processed and producing gelatinization to organic matter of preparation process step one, is beneficial to follow-up polyreaction.
The water vapour spraying of preparation process step 4 effectively can increase the powder adhesion amount of particle surface, improves the Water-saving effect of moisture retaining groundmass.
Beneficial effect of the present invention:
Granule type moisture retaining groundmass of the present invention is raw materials used is biodegradable component, soil can be significantly improved to precipitation and the absorbed dose of pouring water and absorption rate after using, reduce rainwash, simultaneously along with the increase of time, moisture retaining groundmass progressively can be degraded to the nutrient such as soluble nitrogen, phosphorus that can be absorbed and used by plants, and improve soil organic matter content, increase soil beneficial microorganism movable, favourable environment is created in the growth for plant.
The using method of granule type moisture retaining groundmass of the present invention to apply or hole pressing applies for mix post-trenching with soil and fertilizer, also moisture retaining groundmass can be absorbed water and mix with seed, sow after stirring.
Specific embodiments
Below in conjunction with following embodiment, the present invention is described in further detail:
The raw material taking following weight part (kg) is made: W-Gum 65, acrylamide 55, natural pond slag 14, ammonium persulphate 0.3, N, N'-methylene-bisacrylamide 0.5, earthworm excrement 20, vinylformic acid 65, vinegar grain 9, EM microbial inoculum 2;
The concrete steps of the preparation of described moisture retaining groundmass are as follows:
(1) W-Gum is placed in 1 times to the water of its quality, boils heating 35 minutes, for subsequent use;
(2) after step 1 gained material is cooled to room temperature, add vinylformic acid, acrylamide, add sodium hydroxide neutralization after stirring, then add ammonium persulphate, N, N'-methylene-bisacrylamide, reaction system is heated to 90 DEG C of reactions 2 hours;
(3) step 2 gained material is dried at 100 DEG C, be placed in after pulverizer is pulverized and cross 60 mesh sieves, obtain powder for subsequent use;
