Abstract
The invention discloses a granular water-holding substrate with fertilizer retention and fertilizer efficiency improvement functions as well as a preparation method of the granular water-holding substrate. The granular water-holding substrate is prepared from the following raw materials in parts by weight: 55-75 parts of apple peel, 0.1-0.3 part of ammonium persulfate, 5-8 parts of potassium carbonate, 0.4-0.6 part of N,N'-methylene bisacrylamide, 10-12 parts of decomposed coal, 6-7 parts of calcium hydrophosphate, 68-72 parts of potassium acrylate, 70-80 parts of acrylamide and 16-19 parts of soybean meal. The granular water-holding substrate can be jointly used with fertilizer to improve the fertilizer efficiency; through a water absorption function, the fertilizer dissolved in water and several other plant nutrient elements are retained in the granular water-holding substrate; meanwhile, the granular water-holding substrate contains nutrient elements required for plant growth, and can supply the nutrient elements to plants when the plants absorb water, so that the leaching loss of soluble nutrients can be reduced to a certain extent, and the fertilizer utilization ratio can be improved.
Description
Technical field
The present invention relates to a kind of moisture retaining groundmass technical field, granule type moisture retaining groundmass of particularly a kind of fertilizer conservation synergy 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 granule type moisture retaining groundmass of a kind of fertilizer conservation synergy 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: Pericarpium Mali pumilae 55-75, ammonium persulphate 0.1-0.3, salt of wormwood 5-8, N, N'-methylene-bisacrylamide 0.4-0.6, weathered coal 10-12, secondary calcium phosphate 6-7, potassium acrylate 68-72, acrylamide 70-80, soyflour 16-19;
The concrete steps of the preparation of described moisture retaining groundmass are as follows:
(1) put into pulverizer after being dried by Pericarpium Mali pumilae to pulverize, cross 100 mesh sieves, obtain pericarp powder, powder is placed in 1 times to the water of its quality, boil heating 20-40 minute, for subsequent use;
(2) after step 1 gained material is cooled to room temperature, potassium acrylate, acrylamide is added, sodium hydroxide neutralization is added after stirring, add ammonium persulphate, N, N'-methylene-bisacrylamide again, reaction system is heated to 90-110 DEG C of reaction 3-4 hour;
(3) step 2 gained material is dried at 70-90 DEG C, be placed in after pulverizer is pulverized and cross 60 mesh sieves, obtain powder for subsequent use;
(4) weathered coal, salt of wormwood, secondary calcium phosphate, soyflour and leftover materials are dried mixing granulation, grain diameter controls at 1.0-1.5mm, moistening crude to particle surface to particle surface spraying high temperature atomized water steam again, 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 can use to improve effect with fertilizer jointly, by water sorption, the fertilizer be dissolved in the water and some other plant nutrient guarantor are stored wherein, moisture retaining groundmass itself is containing Activities of Some Plants growth desired nutritional element simultaneously, plant utilization can be supplied when plant absorption moisture, reduce the leaching loss of soluble nutrient to a certain extent, improve utilization rate of fertilizer.
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: Pericarpium Mali pumilae 65, ammonium persulphate 0.2, salt of wormwood 6, N, N'-methylene-bisacrylamide 0.5, weathered coal 11, secondary calcium phosphate 6, potassium acrylate 70, acrylamide 75, soyflour 18;
The concrete steps of the preparation of described moisture retaining groundmass are as follows:
(1) put into pulverizer after being dried by Pericarpium Mali pumilae to pulverize, cross 100 mesh sieves, obtain pericarp powder, powder is placed in 1 times to the water of its quality, boil heating 30 minutes, for subsequent use;
(2) after step 1 gained material is cooled to room temperature, add potassium acrylate, acrylamide, add sodium hydroxide neutralization after stirring, then add ammonium persulphate, N, N'-methylene-bisacrylamide, reaction system is heated to 100 DEG C of reactions 3 hours;
