Abstract
The present invention is applicable to the technical field of saline land soil conditioning formula, and provides a saline land dedicated improvement sprinkle fertilizer, and the saline land dedicated improvement sprinkle fertilizer comprises, by mass, 44% to 50% of composted chicken manure, 12% to 20% of coal slime, 15% to 30% of pine needles, 5% to 15% of crude gypsum and 1% to 4% of bentonite clay. The saline land dedicated improvement sprinkle fertilizer is simple in formula, and convenient in application, can effectively reduce soil salinity and PH value, increases the number of soil aggregate structures, promotes plant root growth, improves infiltration capacity and water and nutrient retaining performance, and overcomes the shortages caused by simple chemical modification method.
Description
Technical field
The present invention relates to alkaline land soil and regulate formula technique field, particularly relate to a kind of saltings improvement of special and spread fertilizer over the fields fertilizer.
Background technology
The formation of China's alkaline earth and alkali-affected soil, major part is accumulative relevant with Carbonates In Soil, and basicity is generally higher, and serious salt affected soil regional plant almost can not be survived.Saltings is utilizing in the middle of process, briefly, can be divided into light saltings, moderate saline-alkali soil and heavy saline, and what light saltings referred to it emerges very likely, and saltiness is below 3/1000ths; Heavy saline refers to that its saltiness is more than 6/1000ths, and seedling rate is lower than 50%, and moisture in soil pH value, more than 8.5, causes soil compaction, has restraining effect to the root system of crop, crop is not grown or grows unhealthy; Moderate saline-alkali soil is then between therebetween.
Because in soil, salinity is many, alkalescence is large, and the soil organism is destroyed and runs off, and trace element is in great shortage, hard time glutinous when showing as wet, dry, the normal adularescent salt alkali precipitation of soil table, ventilation, permeable bad, and farm crop root system often has poisoning, rotten, the phenomena of mortality.Even if at this moment dropped into a large amount of fertilizer to be absorbed by farm crop, cause the negative effect of the low output of high investment.China's Saline area accounts for 1/4th of total area under cultivation, and improving the soil physical chemistry present situation of Saline, improve the grain yield of Saline, is an important content of practicable national relevant strategies.
In summary, obviously there is inconvenience and defect in actual use in prior art, so be necessary to be improved.
Summary of the invention
For above-mentioned defect, a kind of saltings improvement of special is the object of the present invention is to provide to spread fertilizer over the fields fertilizer, its proportioning is simple, spread fertilizer over the fields conveniently, the saltiness of effective reduction soil and pH value, increase the quantity of crumb structure in soil, promotes plant root growth, improve infiltration capacity and preserve moisture and fertility performance, overcome the deficiency that simple chemical amendments brings.
To achieve these goals, the invention provides a kind of saltings improvement of special and spread fertilizer over the fields fertilizer, it is made up of Chicken dung, coal slime, pine needle, crude product gypsum and wilkinite, and above-mentioned each constituent mass per-cent configuration is as follows:
Spread fertilizer over the fields fertilizer according to saltings of the present invention improvement of special, the preferred disposition of described Chicken dung, coal slime, pine needle, crude product gypsum and bentonitic mass percent is as follows:
Fertilizer is spread fertilizer over the fields, organic content >=45%, aminoacids content >=12%, moisture content <25% according to saltings of the present invention improvement of special.
Spread fertilizer over the fields fertilizer according to saltings of the present invention improvement of special, described Chicken dung comprises crude protein, fat, ash content, carbohydrate, Mierocrystalline cellulose and N P and K.
Fertilizer is spread fertilizer over the fields, N-P-K content >=5% of described Chicken dung according to saltings of the present invention improvement of special.
The present invention spreads fertilizer over the fields fertilizer by a kind of saltings improvement of special, it is made up of Chicken dung, coal slime, pine needle, crude product gypsum and wilkinite, and described each constituent mass per-cent is configured to: Chicken dung 40% ~ 50%, coal slime 12% ~ 20%, pine needle 15% ~ 30%, crude product gypsum 5% ~ 15%, wilkinite 1% ~ 4%.Saltings of the present invention improvement of special spreads fertilizer over the fields fertilizer, and its proportioning is simple, spreads fertilizer over the fields conveniently, the saltiness of effective reduction soil and pH value, increase the quantity of crumb structure in soil, promotes plant root growth, improve infiltration capacity and preserve moisture and fertility performance, overcome the deficiency that simple chemical amendments brings.Pulverize after above-mentioned Chicken dung, coal slime, pine needle, crude product gypsum, wilkinite pre-mixing according to the above ratio with pulverizer, make granularity be down to below 5mm, then sub-sieve of looking over so as to check after being fully uniformly mixed.The method for making of concrete each composition is as follows:
Described Chicken dung is heavily sprinkled into 0.1% urea by windrow, is heavyly sprinkled into 15 kilograms of calcium superphosphate, is sprinkled into (quick rotting agent is 0.2%, separately adds wheat bran or rice bran pre-mixing) by 0.2% quick rotting agent Preblend by per ton.The moisture controlled of fertile heap is about 50%, and available straw powder regulates humidity, with hold agglomerating, freely land to scatter from 1 meter high and be advisable.
Described coal slime is atmospheric swamp ground product, and venting capability is good, light weight, water holding, fertilizer conservation, is conducive to microbial reproduction, strengthen biological property, nutritious, be namely cultivation matrix, again good soil mediator agent, and containing very high organic matter, humic acid and nutrition.Preferably, its organic content of the peat composed of rotten mosses used in this improving fertilizer is greater than 35%, pH5.5 ~ 7.0, carries out natural air drying before use.
Described pine needle is collected in larch forest and forms through fermenting for a long time, rotting, and is characterized in acid, soft, ventilative, lightweight, is soil improvement optimum feed stock.Preferably, its organic content of the pine needle used in this improving fertilizer is greater than 25%, and pH value 6.0 ~ 7.0 is pulverized raw material and crosses 15 ~ 20 mesh sieves.
The by product of described crude product gypsum source sweetener in large-sized boiler factory, it comprises the compositions such as calcium sulfate, crystal water, calcium carbonate, Calcium hydrogen carbonate, magnesium sulfate, flyash, Soil structure quality can be improved sticky heavy, and long-acting reduction soil pH, increase calcium contents, preferably, described desuifurized or sulphur pH value is less than 7.5.
Described wilkinite take montmorillonite as the non-metallic mineral soil of main mineral constituent, it has strong water absorbability and swelling property, adsorbable 8 ~ 15 times to the water yield of own vol, volumetric expansion can reach several times to 30 times, get bentonite ore soil or ore grind to form powdery, evenly mix in described above-mentioned formula by certain weight ratio, be stirred to evenly by stirring rod.
