Abstract
The invention provides an organotrophic saline soil conditioner. The conditioner is prepared from the following components in percentage by weight: 50%-70% of livestock and poultry wastes, 1%-5% of accelerator, 10%-30% of straw, 8%-15% of powdered rock phosphate or calcium superphosphate, 3%-8% of gypsum and 1%-8% of modifier. When the soil conditioner is applied in the saline alkali soil, the volume weight of the soil can be reduced, the porosity is increased, the velocity of permeability is improved, the water retention capacity is enhanced, the pH value is significantly reduced and the structure of the soil is greatly improved. The application of the soil conditioner promotes the improvement in phosphorus and nitrogen levels and thus the yields of crops are further increased.
Description
Technical field
The invention belongs to soil conditioner technical field, especially relate to a kind of organotrophy type salt-affected soil amendment.
Background technology
Along with the widespread use of soil conditioner in agricultural and ecotope, the product innovation of soil conditioner is also more and more both at home and abroad.Especially recent years, the appearance of efficient low consumption soil improvement agent or amendment, using method update the reduction gradually with cost, make soil improvement agent become possibility in the generally use in land for growing field crops.
Yet the method for traditional alkaline land soil improvement is mainly the sodium utilizing in the displacement soil such as desulfurated plaster or phosphogypsum, and this kind of method is more single, and easily increases the salt of soil, cause the soil weight to increase; Also need in addition many irrigation and drainages, could reduce soil total salt content, increase soil compaction risk.
Soil alkaline ground is except its salt and alkali component is heavier at present, and soil is more raw, and Soil structure is fine and closely woven, and solid-liquid-gas is out of proportion, and these are all the very important problem existing for nutrient deficiency.Therefore in the urgent need to developing a kind of soil conditioner, in improvement soil alkaline, improve Soil structure, increase soil nutrient content, salt affected soil is in various degree become to available good farmland.
Summary of the invention
The first problem that the present invention will solve is for the deficiencies in the prior art, provides a kind of and can realize that soil physico-chemical property improves, suppresses that salinity rises simultaneously, sweetening of the soil alkalescence provide the organotrophy type salt-affected soil amendment of abundant nutritive substance for soil.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of organotrophy type salt-affected soil amendment, described amendment is to be prepared by the component that comprises following weight percentage: 50%-70% animal waste, 1%-5% promotor, 10%-30% stalk, 8%-15% ground phosphate rock or calcium superphosphate, 3%-8% gypsum and 1%-8% conditioning agent.
As preferred scheme, described animal waste is cow dung, pig manure or chicken manure.
As preferred scheme, described promotor is microbial inoculum; As the scheme being more preferably, described microbial inoculum is one or more in bacillus megaterium, subtilis, trichoderma viride, lignocellulose bacterium.
As preferred scheme, described stalk is maize straw or wheat stalk.
As preferred scheme, described ground phosphate rock or calcium superphosphate are crossed 100 mesh sieves.
As preferred scheme, described conditioning agent is ammonium sulfate.
The Second Problem that the present invention will solve is to provide the preparation method of organotrophy type salt-affected soil amendment, and the technical scheme of employing is:
First with pulverizer by crushed stalk, then be uniformly mixed with animal waste, ground phosphate rock, gypsum, promotor and conditioning agent, after fermenting, becoming thoroughly decomposed, drying machine is dried, the sub-sieve of looking over so as to check, bagging and packaging.
Advantage and positively effect that the present invention has are:
1, this soil conditioner makes by fermentation, and its full phosphorus, full nitrogen, organophosphorus content and unleavened product comparison, obviously increase.
2, this soil conditioner is used on salt affected soil, the unit weight of soil reduces, and porosity increases, and seepage velocity improves, and protects water-holding capacity and strengthens, and pH value significantly reduces, and Soil structure is greatly improved.
3, this soil conditioner being used in to Tianjin Binhai salt-affected soil (total salt content is in 0.22%-0.5% scope) test confirms, do not having under the condition of sufficient water resource washed off soil salinity, use in right amount organic and inorganic soil conditioner in the situation that not changing soil salt content, can improve crop yield, illustrate that this soil conditioner can improve the salt resistant character of crop; Have and under enough water conditions, use novel saline-alkali soil amendment and promoted drench the efficiency of salt and strengthen the rapid desalting effect of soil with water.
Embodiment
Below in conjunction with specific embodiment and application examples, the present invention is elaborated.
Embodiment mono-
Get weight percentage and be 30% maize straw, first with pulverizer, pulverize, then with 50% chicken manure, after 10% ground phosphate rock, 5% gypsum, 2% ammonium sulfate and 3% microbial inoculum (microbial inoculum is that bacillus megaterium, subtilis, trichoderma viride and lignocellulose bacterium are mixed to get with arbitrary proportion) are uniformly mixed, natural condition bottom fermentation 50 days, drying machine drying, the sub-sieve of then looking over so as to check, pack package.
Embodiment bis-
Get weight percentage and be 20% maize straw, first with pulverizer, pulverize, then with 60% pig manure, after 10% ground phosphate rock, 5% gypsum, 3% ammonium sulfate and 2% microbial inoculum (microbial inoculum is that bacillus megaterium, subtilis, trichoderma viride and lignocellulose bacterium are mixed to get with arbitrary proportion) are uniformly mixed, natural condition bottom fermentation 50 days, drying machine drying, the sub-sieve of then looking over so as to check, pack package.
Embodiment tri-
Get weight percentage and be 10% wheat stalk, first with pulverizer, pulverize, then with 70% cow dung, after 10% calcium superphosphate, 5% gypsum, 4% ammonium sulfate and 1% microbial inoculum (microbial inoculum is that bacillus megaterium, subtilis, trichoderma viride and lignocellulose bacterium are mixed to get with arbitrary proportion) are uniformly mixed, natural condition bottom fermentation 50 days, drying machine drying, the sub-sieve of then looking over so as to check, pack package.
Reference examples:
CK is quantitative cow dung and stalk fermentation thing, quantitatively ground phosphate rock, the quantitative mixture of gypsum; TS4 is the amendment that embodiment tri-prepares, and is cow dung, stalk, ground phosphate rock, gypsum, promotor and conditioning agent are carried out to combined fermentation finished product afterwards.Through overtesting detected result, confirm: this soil conditioner combines relatively with contrasting (simple material combination: cow dung stalk fermentation thing, ground phosphate rock, gypsum), and its full phosphorus, organophosphorus, total nitrogen content obviously increase.Concrete detected result is as follows:
This item of table 1 research amendment and CK compost chemistry and Biological indicators contrast
Application examples:
Pilot product is carried out to field experiment.Experimental field be selected in great Su village village, the peaceful town of Dagang District, soil property: organic matter 1.37%, alkali-hydrolyzable nitrogen 117.4mg/kg, rapid available phosphorus 62.17mg/kg, available potassium 214.12mg/kg, total salt 0.43%.Corn experimental cultivar Nongda108.2 processing are established in test, process blank and the amendment that applies embodiment tri-, consumption 1.2t/ mu.Amendment is applied to soil 15～20cm place.Every mu applies urea 15kg, diammonium phosphate 8kg, potassium sulfate 5kg.The test-results soil weight after 1-2 that confirms to be manured into soil reduces, and soil porosity increases, and the seepage velocity of soil improves, and the ability that soil is protected retaining strengthens, and soil pH value significantly reduces, and soil organic matter content increases.Therefore, Soil structure improves greatly.Novel conditioning agent is used and has been promoted soil phosphorus and nitrogen level to improve, and then increases the output of corn crop.Concrete outcome refers to form below.
