Description

A kind of corn furrow mechanical deep fertilizing fertilizer method

Technical field:

The present invention relates to proportion of crop planting fertilizer practice field, be specifically related to a kind of corn furrow mechanical deep fertilizing fertilizer method.

Background technology:

Corn another name: maize, maize, large ear of maize, corn ear of maize, beautiful another name for Sichuan Province, jade slip etc.

Corn have the laudatory title of life prolonging food, contains rich in protein, fat, vitamin, trace element, cellulose and polysaccharide etc., and great potential and the corn with the high nutrition of exploitation, high biological function food have the effects such as fat-reducing longevity.

And corn is all to belong to main cultivation crop in many areas of China, be all large-area plantation throughout the year, for the height of the availability of fertilizer, be that output is had to very large impact.And common fertilizing method cannot be accomplished high utilization rate of fertilizer, so just, having limited the raising of output aspect fertilising, so just may cause output not catch up with needs, brought unnecessary trouble.

Summary of the invention:

Technical problem to be solved by this invention is to overcome existing technological deficiency a kind of a kind of corn furrow mechanical deep fertilizing fertilizer method that method is reasonable, step is clear, cultivation effect is good is provided.

Technical problem to be solved by this invention adopts following technical scheme to realize:

A kind of corn furrow mechanical deep fertilizing fertilizer method, is characterized in that: comprises the following steps,

Step 1, whole and apply base fertilizer: the mode that adopts agricultural machinery to combine with agronomy, April, early and middle ten days carried out the whole ground of stubble-cleaning every year, the ditch that slits in former furrow before whole ground applies base fertilizer, execute 46% urea 7kg, 64% diammonium phosphate 20kg, 50% potassium chloride 10kg, zinc sulphate 1.5kg for every mu, or 44% containing measuring native formula fertilizer 50kg, inferior to layer by layer manuring in the body of ridge, fertilization depth 15-18cm;

Step 2, select suitable instrument: select supporting device for mechanical and the light plough of topdressing to support the use, with large plough band limit, single body seeder banding ridge, topdress in furrow;

Step 3, select suitable chemical fertilizer: chemical fertilizer is selected ammonium nitrate prill, urea, consumption adopts surveys soil formula, also can adopt conventional fertilizer application amount, and every mu imposes urea 20-25kg, the degree of depth of topdressing 8-15cm, thickness of earth covering 5-7cm;

Step 4, topdress: the optimum period of topdressing is in corn jointing or typhon mouth phase, corn thorax two, carry out while playing large ridge, has plowed large ridge everywhere, topdresses and synchronously completes in good time;

Step 5, supporting agronomy:

5.1, select improved seeds: seed purity is not less than 98%, cleanliness is not less than 99%, germination rate is not less than 95%, moisture content is not more than 16%, sow the 2-3 days that basks seeds, select 20% fourth sulphur good fortune Tebuconazole suspension seed-coating agent or 8.1% gram of penta triazolone suspension seed-coating agent, carry out seed pelleting prevention and elimination of disease and pests, can carry out seed pelleting by pesticide-seeds ratio 1:35-45;

5.2, meticulous whole ground: adopt SGTN-280 model twin shaft combined soil preparing machine, carry out stubble-cleaning, rotary tillage, subsoiling, fertilising, ridging, suppression and work continuously, accomplish that ground grading is broken, excess in the upper and deficiency in the lower, without trash, more than ploughing warm and sunny degree of depth 25cm;

5.3, begin sowing in good time: when the clever topsoil of soil 5-10 is stable, by 5-6 ℃, can sow, adopt the precision drilling of 2BJ2 precision planter.Fertilising recoil drainage, covers seed manure;

5.4, rational close planting: according to variety characteristic and cultivation mode, select suitable planting density;

5.5, topdress: when corn enters the typhon mouth phase, topdress in good time;

5.6, prevention and elimination of disease and pests: control of maize snout moth's larva adopts BT emulsion, kills soon the agricultural chemicals of the efficient low toxicity and low residue such as spirit.Disease is mainly northern and southern leaf blight, at corn, takes out male front and back to 50% carbendazim WP 500-600 times liquid or 70% thiophanate methyl WP800-1000 times of liquid spraying for morbidity field;

5.7 results in good time: accelerating precipitation, putting autumn ridge, in the stalk airing that strips off the skin of standing of corn wax ripeness middle and later periods, improve seed maturity, is to reduce water content, can receive 15-20 days evening, and essence is received thin receipts.

Beneficial effect of the present invention is: very simple and clear of above-mentioned steps, be applicable to professional personnel's operation, and be also applicable to non-professional personnel, operate, and the cost of said method is not high, more higher than the efficiency of artificially applying fertilizer by mechanical deep fertilizing fertilizer, precision is more high, and effect is more good, and has reduced a large amount of fertilization times.The inventive method is reasonable, step is clear, cultivation effect is good.

Embodiment:

For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below further set forth the present invention.

More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
