Abstract
The invention discloses a fertilizer for corns in the saline-alkali soil and an application thereof, belonging to the technique of soil improvement and efficient fertilization, solving the problems of easiness in soil hardening, bad soil structure, bad tilth, and low bioavailability of nutrients required by corn growth caused by high pH and high salinity. The fertilizer for corns in the saline-alkali soil comprises 7.3 weight parts of sulfurous fertilizer, 10 weight parts of humic acid, 24 weight parts of N, 12 weight parts of P2O5, and 6 weight parts of K2O. When the fertilizer is applied, the application amount is 50kg/mu. The fertilizer disclosed herein is suitable for corn production in the saline-alkali soil, can improve the physical and chemical property of the soil and reduce the accumulation of salts on the soil surface, and can raise the corn yield by 20-30%.
Description
Technical field
The invention belongs to soil improvement and efficient fertilizer practice, relate to a kind of saltings corn special-purpose fertilizer and application thereof.
Background technology
Salt affected soil is of poor quality, and the validity of the nutritive element that growth and development of plants is required is low, causes plant root system development bad, and the plant body is unhealthy and strong, has a strong impact on crop yield.People have proposed the method for various soil improvements at present, but also a kind of highly effective salt affected soil modification method are not used for reality, and are that modifying agent and the special-purpose fertile integrated product application that is combined into one of crop is unactual in producing.
Patent 99112075.2; A kind of agricultural soil ameliorant is disclosed; Borax, sal epsom, zinc sulfate, copper sulfate, gypsum, spectrophotometric, manganous sulfate, sulphur, ferrous sulfate by certain parts by weight proportioning are formed; The structure of can improving the soil, but through on probation, the effect of finding this modifying agent is unstable very.
Patent 200910035391.X discloses a kind of biological soil conditioner and application of phosphogypsum, through suitability for industrialized production, with the solid waste phosphogypsum recycling of phosphorous chemical industry enterprises such as phosphate fertilizer plant, phosphoric acid factory generation.But gypsum, calcium chloride, acid or the material (like sulfuric acid, ferric sulfate) that generates by acid; Though can expect the physico-chemical property of soil improves; But use in a large number and effect stable aspect also have problems, and these goods, materials and equipments can not improve the necessary nutrient of plant.
Patent 89106609 discloses a kind of special purpose complex fertilizer for saline-alkali soil, and it mixes zeolite with mud coal and an amount of nitrogenous, phosphoric fertilizer; And added a small amount of trace element zinc; It is applied in the salt affected soil, and to change the structure of soil, harmful ion is to the harm of plant in the reduction soil.In salt affected soil, use, though can play the effect of certain crop yield, the interpolation of nitrogen phosphorus nutrient is not carried out nutrient demand according to crop, has the irrational problem of nutrient proportioning, and nitrogen phosphorus nutrientuse efficiency is not high.
Corn is one of most widespread food crop in the world, also is important crops and important feed resource.China saltings distributes extensively; But existing various corn fertilizer; Can not effectively solve salt affected soil because problem such as the soil that high pH and high salinity cause is prone to harden, Soil structure is abominable can't satisfy the corn nutrient demand in the time of infertility, corn yield increasing is lower.
Summary of the invention
The present invention is in order to solve salt affected soil because the problem that the soil that high pH and high salinity cause is prone to harden, Soil structure is abominable, tilth is poor, fertility is low, the biological effectiveness of the required nutrient of corn growth is low, and a kind of saltings corn special-purpose fertilizer and application thereof are provided.
The present invention realizes through following technical scheme:
A kind of salt affected soil corn special-purpose fertilizer comprises each component of following weight part:
Sulfur fertilizer 7.3 humic acidss 10 N 24 P
2O
512 K
2O 6.
Further, comprise that also weight part is 0.4 trace elements zn.
Described sulfur fertilizer is a sulfur-coated urea, can reduce pH in soil, improves soil physical property, can also become the supply source of the essential composition of plant;
Described trace elements zn is a macrobead zinc sulfate.
Described humic acid is the particle nitro humus acid, C 50-65% wherein, H 4-6%; Remaining major part is O, and humic acids can reduce soil pH value, activation plant rhizosphere difficultly soluble nutrient; Promote the absorption of root system, can improve the physiologically active of roots of plants trace elements zn and P.
Described fertilizer is the mixture of the sulfur-coated urea of mass ratio 1:0.18:0.58:0.23, common granular urea, phosphorus two ammoniums, macrobead Repone K, can satisfy corn nutrient demand in the time of infertility.
During preparation, above-mentioned each component is processed particulate state fertilizer according to ordinary method.
The application of above-mentioned salt affected soil corn special-purpose fertilizer, amount of application are 50kg/ mu.
Compared with prior art, the present invention has following outstanding effect:
(1) improves soil aggregate, alleviate soil compaction, provide tilth to a soil;
(2) increase soil fertility, effectively activate the validity of salt affected soil insoluble phosphorus potassium and trace element zinc, manganese etc.;
(3) can make 0.5-1.0 unit of soil pH decline in slight and heavy salinized soil Application;
(4) can make soil total salt quantity decline 15-30% in slight and heavy salinized soil Application;
(5) the fertilizer efficiency Gao Erwen of fertilizer, longer duration can satisfy corn and grow normally, need not to topdress again, and is easy to use.
The present invention is applicable to the application of Maize Production on the salt affected soil; Especially after the salt affected soil of pH value more than 8.0 used this fertilizer, the physico-chemical property of soil can be improved, gathering of soil surface salt can also be alleviated; Reduction with soil pH value; The activation of nutrients such as corn rhizosphere soil phosphorus zinc, the input of the macronutrient of suitable corn growth can improve corn yield 20-30%.
