Description
Technical field
The present invention relates to Crop fertilizer field, be specifically related to a kind of millet special fertilizer and application process thereof.
Background technology
Millet is as first of five cereals, and be described as the nurture crop of the Chinese nation, be the characteristic rain fed crops of China, to the wide adaptability of soil, output is relatively stable.At present, although be no longer main food crop from millet the whole nation, but still be the important food crop of Arid Region of Northern, in the dry farming ecological agriculture, in the grain security ensureing arid, desert, play very important effect.Nutritive Value of Millet is high, easy to digest, the amino acid such as the indispensable tryptophane of rich vitamin A, VITMAIN B1, Lin Suanna Vitamin B2 Sodium Phosphate etc., particularly human body, methionine(Met).In recent years, along with the raising of people's living standard, the multifarious demand of diet formula, to the progressively attention of food nutrition, health and safety, society and the demand of market to millet progressively increase.
At present, the fertilizer amount of China increases year by year, and utilization rate of fertilizer is not high, and especially loss of nitrogen fertilizer approach is many, loss amount large, produces serious negative impact to underground water, surface water and atmospheric environment.In millet production process, also there is same problem, Term Fertilization mainly relies on peasant household's experience, random strong selecting of fertilizer, lacks the guidance of science.Let alone rational application of fertilizers and fertilizer efficiency utilization.Therefore, in millet production process, need the fertilizing method of a kind of efficient Fertilizer Combinations formula and science badly.
Summary of the invention
For many weak points that prior art exists, the invention provides a kind of millet special fertilizer and application process thereof, this fertilizer is millet dedicated fertilizer, be made up of urea, calcium superphosphate and potassium sulfate, form more simple than existing fertilizer, use conveniently, and by coordinating with special fertilizing method, postponing nitrogen, allotment nitrogenous fertilizer base manure, proportion of additional fertilizer, topdress in key developmental stages, pour water, substantially increase fertilizer efficiency, when fertilizers input reduces, ensure that millet high yield, increase economic benefit, reduce the potential risk to environment.
Concrete technical scheme of the present invention is:
A kind of millet special fertilizer, every mu of fertilizer amount is counted:
Urea 14 ~ 18kg, available phosphorus content is the calcium superphosphate 30 ~ 35kg of 18wt%, and effective potassium content is the potassium sulfate 18 ~ 22kg of 51wt%.
Wherein urea selected by nitrogenous fertilizer, and nitrogen content is high, and physical behavior is good, without minor component, makees base manure and topdress, should be used for foliage top dressing;
Phosphate fertilizer ssp dnab, should make base manure, and fertilizer efficiency is stablized;
Potassium sulfate selected by potash fertilizer, prevented from caking, is convenient to use, and directly can absorb for millet, can reduce the soil acidification risk of applying fertilizer and causing simultaneously, should use as base manure.
Above-mentioned three kinds of fertilizer are easy to be easy to get, and is easy to use.
According to the uptake characters of millet, often producing 100kg millet seed needs nitrogen 2.5-3.0kg, phosphorus 1.2-1.4kg, potassium 2.0-3.8kg; Calculate when millet per mu yield 350 kilograms accordingly, nitrogen 8.8-10.5kg will be absorbed from soil, phosphorus element 4.2-4.9kg, potassium element 7.0-13.3kg; And in order to meet the needs of this output in prior art, general control fertilizer application amount is: urea 32.6kg, available phosphorus content is the calcium superphosphate 33.3kg of 18wt%, and effective potassium content is the potassium sulfate 19.6kg of 51wt%;
On the basis of above-mentioned prior art, it is too high that contriver furthers investigate its amount of urea of rear discovery, not only environment is had a significant impact, also the planting cost of millet is considerably increased, the output of Use out of range to millet does not have beneficial effect yet simultaneously, therefore contriver is optimized it, and the optimum spraying amount of acquisition is: every mu of fertilizer amount is counted:
Urea 16.3kg, available phosphorus content is the calcium superphosphate 33.3kg of 18wt%, and effective potassium content is the potassium sulfate 19.6kg of 51wt%;
Compared with fertile consumption usual in prior art, when maintaining phosphorus, Potassium Fertilizer and being constant, nitrogen fertilizer amount reduces 50%, greatly reduces because of loss of nitrogen fertilizer the environment particularly potential risk that causes of groundwater environment; Total nutrient consumption also reduces by 24.2%, and greatly reduce the fertilizer cost in millet production, the yield and quality simultaneously for millet does not all affect, and extremely meets the requirement of the ecological agriculture.
In addition, more important point of the present invention there is provided the application process of above-mentioned millet special fertilizer, and concrete grammar is:
Postponing nitrogen, allotment nitrogenous fertilizer base manure: proportion of additional fertilizer is mass ratio 1:2;
Concrete steps are: by 1/3 urea, full dose calcium superphosphate and full dose potassium sulfate as base manure, spread fertilizer over the fields in millet earth's surface, and deep plough 30cm afterwards, then sows, and manages according to normal field management method; In millet elongation-heading stage, residue 2/3 urea is topdressed, spread fertilizer over the fields in millet earth's surface, then water immediately, be advisable with moistening 15cm soil layer.
More existing urea is based on base manure, and topdressing is auxiliary application process, and this technology, by most of postponing nitrogen, had both met the nitrogenous fertilizer supply in Growth of Millet early stage, and in turn ensure that the heavy demand of jointing-booting stage to nutrient; Topdress in millet key developmental stages, irrigate simultaneously, planned strategies for by liquid manure, not only meet the heavy demand of jointing-booting stage to moisture, and in the significantly reduced situation of total nitrogen quantity, improve utilization rate of nitrogen fertilizer and grain number per spike, be beneficial to the volume increase of millet.
Compared with prior art technical scheme of the present invention has following advantages and positively effect:
1. to lose weight synergy: the total consumption of fertilizer reduces by 24.2%, in the significantly reduced situation of fertilizer cost, ensure that millet high yield, and millet output increases by 18.2%, adds economic benefit;
2. postponing nitrogen: allotment base manure, nitrogen fertilizer amount ratio of topdressing, by most of postponing nitrogen, increases the consumption that topdresses, reduce base manure consumption, under the nitrogenous fertilizer supply meeting Growth of Millet early stage, ensure that the heavy demand of jointing booting critical period to nutrient, ensure that the stable yields volume increase of millet;
3. utilization rate of fertilizer is high: under the prerequisite that total nitrogen consumption reduces, and produces key developmental stages (jointing-booting stage) and topdresses, in conjunction with irrigation, planned strategies for, improve utilization rate of nitrogen fertilizer, guarantee millet high yield by liquid manure in millet;
4. environmental friendliness: fertilizer amount reduces, particularly nitrogen fertilizer amount reduces by 50%, and Bound moisture divides to be planned strategies for, and reduces the Pollution risk because fertilizer loss causes underground water, surface water and atmospheric environment; The reduction of fertilizer amount, also reduces the energy consumption of chemical fertilizers production simultaneously;
5. balance fertilizing: nutrient is complete, nitrogen, phosphorus, potash fertilizer with the use of, meet Growth of Millet demand.
