Description
Technical field
The present invention relates to corn technical field of fertilizers, particularly relate to a kind of drip irrigation corn special containing carbon element water-soluble fertilizer.
Background technology
Water-soluble fertilizer is a kind of quick-acting chemical fertilizer, and its essential characteristic is good water solubility, can be dissolved in the water completely, can directly be absorbed by the root system of crop and blade face.In water-saving agriculture, use water-soluble fertilizer by the Integration of Water into Fertilizer, first can bring into play rich water synergistic effect, the utilising efficiency of fertile and water is all obviously improved, the 2nd, fertilizer efficiency is fast, can solve the high-yield crop nutritional needs in whole vegetative period.The exploitation of science and appropriateness and to promote water-soluble fertilizer be the needs that meet modern intensive agricultural planting production standard, is the needs that ensure agricultural-food High yield, is the needs of precise management water resources and nutrients resource.
CO in atmosphere
2gas concentration is in about 350ppm, and the photosynthetic efficiency of farm crop required CO when maximum
2concentration is generally at 800～1200ppm, therefore under the satisfied condition of liquid manure, uses CO
2gas increases plant canopy CO
2concentration is to improving crop photosynthesis efficiency and output important role.Land for growing field crops agricultural is the space of an opening, CO
2how use to solve large Tanaka and be uniformly distributed, discharge uniform problem and become the task of top priority.
Corn drip irrigation cultivation has now become arid and semi-arid area and has realized the Main Cultivation mode of high yield, be evenly distributed in plant root soil by water-fertilizer integral, meet the demand of drip irrigation corn to various nutrients, realize Tree Precise Fertilization, improve utilization rate of fertilizer, and meeting the special carbon element water-soluble fertilizer of corn growth stage nutrient demand, also do not have present stage, therefore exploitation is applicable to the proiprietary formula carbon element water-soluble fertilizer of drip irrigation corn growth demand, further raising utilization rate of fertilizer, reduction fertilizer amount and cost improves crop yield simultaneously and quality becomes urgent need.
Summary of the invention
In view of this, the embodiment of the present invention provides a kind of drip irrigation corn special containing carbon element water-soluble fertilizer, and main purpose is to solve the CO that carbon containing fertilizer discharges after use in land for growing field crops
2skewness, and in existing dropper corn planting, be not applicable to the proiprietary formula carbon element water-soluble fertilizer problem of drip irrigation corn growth demand, further to improve utilization rate of fertilizer, to reduce fertilizer amount and cost, improve corn yield and quality simultaneously.
In order to solve the problems of the technologies described above, the present invention has adopted following technical scheme:
First determine fertilizer nutrient proportioning.Xinjiang 100 kilograms of corn kernels of every production need nitrogen 2.6kg, phosphorus (P
2o
5) 0.96kg, potassium (K
2o) 2.18kg.The nitrogen nutrient absorbing after jointing accounts for 72%, phosphorus nutrient accounts for 82%, potassium nutrition accounts for 77%, need nitrogen 1.87kg, phosphorus 0.79kg, potassium 1.68kg, In The Soil of Xinjiang generally lacks the rich potassium of the few nitrogen of phosphorus, can meet 30% needs by 1000 kilograms of corn Nitrogen In Soils of per mu yield, and phosphorus can meet 30% needs, potassium can meet 80% needs, need to supplement nitrogen 13.1kg, phosphorus (P
2o
5) 5.53kg, potassium (K
2o) 3.36kg.Press 30cm+90cm wide-and narrow-row and arrange, the capable Nei Pu of 30cm drip irrigation zone, all fertilizer is executed with water droplet, by with water droplet nitrogen fertilizer application utilization ratio 60%, phosphate fertilizer 30%, potash fertilizer 70%, need to drip fertilise nitrogen 21.8kg, phosphorus (P
2o
5) 18.4kg, potassium (K
2o) 4.8kg, proportioning is 1:0.85:0.22, can meet the corn jointing needs of growth later.
According to nutrient proportioning, select raw material, determine various proportioning raw materials.The embodiment of the present invention provides a kind of drip irrigation corn special containing carbon element water-soluble fertilizer, composed of the following components:
Water-soluble carbon fertilizer 64～65 weight parts, described water-soluble carbon fertilizer is carbonated and nitrogen and water-soluble fertilizer;

As above containing carbon element water-soluble fertilizer, preferably, the content >=46wt% of potassium oxide in described water soluble potassic fertilizer.More preferably, described water soluble potassic fertilizer is one or both in Repone K or saleratus.
As above containing carbon element water-soluble fertilizer, preferably, micronutrient levels >=20% weight in described water soluble trace elements fertilizer.More preferably, described water soluble trace elements fertilizer is with being selected from solubility Zn salt, boric acid or polymerization boron, soluble M n salt, Dissolvable Fe salt, soluble Cu salt, soluble M o salt, and that selects to lack according to soil nutrient status severally carries out complex reaction and make.More preferably, described solubility Zn salt is that zinc sulfate, described soluble M n salt are that manganous sulfate, described Dissolvable Fe salt are that ferrous sulfate, described soluble Cu salt are that copper sulfate or cupric nitrate, described soluble M o salt are ammonium molybdate.
The special preparation method containing carbon element water-soluble fertilizer of drip irrigation corn of the present invention is: according to required fertilizer gross weight, according to the each constituent mass of listed as parts by weight.Then load weighted water-soluble carbon fertilizer, water soluble phosphorous fertilizer, water soluble potassic fertilizer and water soluble trace elements fertilizer are mixed and can obtain containing carbon element water-soluble fertilizer.
The special using method containing carbon element water-soluble fertilizer of drip irrigation corn of the present invention is: use age and consumption: jointing stage-heading stage: drip 2～3 times, and each irrigation quantity 35～40m
3, execute 25～30 kilograms of special fertilizers with water droplet at every turn.Heading stage-ripening stage: drip 2～3 times, front 2 filling amount 35～40m
3/ mu, each dripping executed 15～25 kilograms of special fertilizers, last 1 water filling amount 30m
3/ mu, drips and executes 10 kilograms of special fertilizers.
Compared with prior art, beneficial effect of the present invention is: according to soil fertility basis, according to corn regulation of fertilizer requirement, the special carbon element water-soluble fertilizer of preparation drip irrigation corn, be evenly distributed in plant root soil by water-fertilizer integral, meet the demand of drip irrigation corn to various nutrients, realize Tree Precise Fertilization, improve utilization rate of fertilizer.The fertilizer of producing according to method provided by the present invention is crystal powder powder, is conducive to fertilizer and dissolves and prevented from caking fast.Can be dissolved in the water rapidly containing carbon element water-soluble fertilizer, be evenly distributed in plant root soil with water, in Crop nutrient, after carbon raw material decomposition and inversion, discharge CO
2gas, because carbon raw material is used with water, carbon raw material is more even in large Tanaka's distribution, the CO discharging
2gas is also more even, has solved the technical barrier that carbon containing fertilizer is uniformly distributed and effectively discharges in large Tanaka uses.
