Abstract
The invention relates to a special fertilizer for corn. The fertilizer is composite fertilizer or compound fertilizer obtained by adding fillers in nitrogen, phosphorus and potassium according to a certain proportion, and is characterized in that nutrient proportions of nitrogen to phosphorus to potassium is 10-14:4-6:7-9. The fertilizer is small in loss after being applied; nitrogen easily absorbed by plants is released gradually during a hydrolysis or biolysis process, so that the applied fertilizer can be fully utilized by the plants; volatilization loss of nitrogen in soil can be reduced; and formation of nitrate nitrogen is reduced, so that leaching loss and denitrification loss are reduced and further generation and emission of nitrate, nitrite, ammonia and nitrous oxide are reduced. The fertilizer has the advantages of increasing utilization rate of the fertilizer, reducing usage amount of the fertilizer and reducing labor for fertilization, can effectively alleviate the problems of excessive consumption of resources, large pollution of agricultural non-point source and high agricultural production cost, and is green fertilizer capable of promoting sustainable development of the soil resource.
Description
Technical field
The present invention relates to a kind of fertilizer, be specifically related to a kind of corn fertilizer that is applicable to corn planting region.
Background technology
Corn is the staple food crop of China, have the laudatory title of life prolonging food, contain rich in protein, fat, VITAMIN, trace element, Mierocrystalline cellulose and polysaccharide etc., nowadays become a kind of protective foods of hot topic, often come across on people's dining table, there is the great potential of the high nutrition of exploitation, high biological function food; Corn is simultaneously also the raw material of feed and following bioenergy, along with rural laborer shifts to city, take a lot of work the deep application of fertilizer of effort and repeatedly fertilizer practice on corn, be difficult to implementation.The single fertilization of corn requires: 1, nutrient reasonable ratio, meets the demand of whole breeding time of corn to nutrient substantially; 2, utilization rate of fertilizer is high, environmental friendliness; 3, do not reduce output, even volume increase; 4, do not reduce quality, even promote quality; 4, easy to use, even can realize mechanized application; The sustainable utilization ability that 5, can maintain soil, even improves soil, culture fertility.
In prior art, the ordinary method of corn fertilizing is applying seed manure at seeding time, before corn jointing, once intertills, topdresses, and has time-consuming, effort; And owing to adopting top application, be difficult to directly act on maize root system while topdressing, assimilated efficiency is low, simultaneously large with the probability of ammonia volatilization and rainwash loss, utilization rate of fertilizer is lower.In recent years, along with the increase of slow-release fertilizer processing amount, scholar becomes focus gradually to the research of slow-release fertilizer.Be Base-appling once equally, slow-release carbamide is than common urea volume increase 10.2%; That base imposes in conjunction with slow-release carbamide than common urea volume increase 7.1% equally.Common urea utilization ratio only has 30%, and slow-release carbamide can reach 40%～50%.Along with the rising of agriculture recruitment cost and the development of agricultural on a fairly large scale, for adapting to current production management pattern, reduce the fertilising amount of labour used, the new-type fertilizer that the single fertilization of exploitation corn is used is extremely urgent.
Summary of the invention
For the problems referred to above, the invention provides a kind of corn fertilizer, its object is: according to the nutrient situation of corn growth regulation of fertilizer requirement and soil, slow-release fertilizer oxamide and the compound technology of organic-inorganic are carried out to significant improvement, realize the nitrogen that progressively discharges plant in fertilizer hydrolysis or biological decomposition process and be easy to absorb form, meet the demand of a season crop to various nutrition, the later stage needn't topdress; Meanwhile, this incorporation of fertilizerin the soil fertilizer is difficult for being taken away by current afterwards, reduces volatilization, avoids or reduces the pollution of water body and atmosphere, thereby improve utilization rate of nitrogen fertilizer, cuts the waste.
Technical solution of the present invention:
Corn fertilizer, for composite fertilizer or Chemical Mixed Fertilizer that nitrogen, phosphorus, potassium add certain stopping composition to obtain according to a certain ratio, is characterized in that: the nutrition proportion by subtraction of described nitrogen, phosphorus, potassium is: 10 ~ 14:4 ~ 6:7 ~ 9.
Described nitrogen, phosphorus, the preferred nutrition proportion by subtraction of potassium are 12:5:8, and its total nutrition divides and at least reaches 25%.
Described nitrogenous fertilizer nitrogenous source is: in urea, ammonium sulfate, ammonium chloride at least one.
Described phosphate fertilizer phosphorus source is: in monoammonium phosphate, diammonium phosphate, calcium superphosphate, double superhosphate, fused(calcium magnesium)phosphate at least one.
Described potash fertilizer potassium source is: in potassium sulfate, Repone K at least one.
Described zinc fertilizer is zinc sulfate.
Described stopping composition is for comprising containing supporting weighting material and Investigation on Wet Granule Packing thing.
Described containing supporting weighting material for fermentation animal manure and the peat composed of rotten mosses.
Described Investigation on Wet Granule Packing thing is attapulgite and decomposes stone flour.
Described fermentation animal manure can be fermentation sheep excrement, fermentation poultry dung, fermentation cow dung.
As preferably, described corn fertilizer by urea, monoammonium phosphate, Repone K, boron fertilizer, zinc sulfate, attapulgite, decomposition stone flour, fermentation animal manure, the peat composed of rotten mosses by proportioning per ton is: 235:105:130:5:10:95:35:250:135 makes.
Beneficial effect of the present invention:
First,, compared with conventional composite fertilizer, this fertilizer has two large advantages.First, this fertilizer effectively controlled release nitrogen discharges, and Base-appling once also can ensure the timely supply of corn whole breeding time of nitrogen, there will not be the phenomenon of burning seedling, hindering root and early stage high nitrogen, later stage denitrogenation, save manually in minimizing chemical fertilizer input amount simultaneously, be convenient to management.The second, this fertilizer compatibility a certain proportion of fertilizer, be conducive to the sustainable use of soil, even improve soil, culture fertility.
Secondly, compared with coated fertilizer, in price, because synthesizing of the critical materials synthetic relevant to oxamide obtained important breakthrough, the cost of oxamide has obtained significantly reducing, and its price is slightly higher than commercially available urea.By compound with phosphorus potash fertilizer, and after the certain organic fertilizer of blending, this fertilizer has more strong advantage in price.In environmental friendliness, this fertilizer slow-release nitrogen fertilizer oxamide used belongs to amides fertilizer, and it can be by microorganism slow degradation in soil, and final product is carbonic acid gas, ammonium nitrogen and water, can not cause the secondary pollution of soil.
Finally, compared with common organic-inorganic compound (mixing) fertilizer, this fertilizer can ensure that nitrogenous fertilizer is long-term, stable supplying, and to inhale fertile rule consistent with corn.The corn single fertilization of this project development with new-type fertilizer have that fertilizer efficiency is good, moderate, environmental friendliness etc. is specific, product is due to current commercially available various corn fertilizer, meet the demand for development of Eco-agricultural Economy environment-friendly high-efficiency, applied range, market outlook are wide, have the good market outlook power that takes part in international competition.
