Description
Technical field
The invention belongs to corn planting methods, especially related with a kind of wide film wide-and narrow-row corn planting method.
Background technique
Ordinary maize implantation methods are to give free rein to grow, about 1.5 ruler of line-spacing, about 1.2 ruler of spacing in the rows, per acre substantially
3000-3500 plants, general corncob produces 0.4-0.5 jins or so, i.e., traditional product per mu yield is at 1000-1500 jins or so.For
For populous China, demand is much not achieved in such per mu yield.The method of existing west area maize planting is logical
Narrow film laying is planted, however the effect is unsatisfactory, and the present invention provides a kind of corn plantings that can be realized high yield
Method, not additionally using high cost planting machinery and the purpose for realizing high yield in the case where increasing labour cost.
Summary of the invention
The present invention is intended to provide a kind of high density, wide overlay film, wide-narrow row planting and the wide film wide-and narrow-row jade that yield can be improved
Rice implantation methods.
For this purpose, the invention adopts the following technical scheme: wide film wide-and narrow-row corn planting method, characterized in that particular technique
Are as follows:
Seed selection: using the big fringe of thin planting of resistance to close anti-fall kind as corn planting kind;
Trench digging: using the width of 150cm as a band, it is spaced 50cm between band and band, it is alternate to form four row wide-narrows on tape
Seeding corn seed furrow, be used as narrow row between two rows of outer two sides, narrow row line-spacing is 35cm, between intermediate adjacent rows
As wide row, the head offices of two wide rows is away from for 80cm;
Sowing: it in the line-spacing of corresponding wide-and narrow-row seed furrow, is sowed by four line seeder of a film, and on tape
Cover wide film.
As supplement to above-mentioned technical proposal and perfect, the invention also includes following technical characteristics.
Going out in the wide film wide-and narrow-row corn planting method combination trickle irrigation setting with what the pearl seedling on wide-and narrow-row cooperated
Mouth or water dropper carry out water saving irrigating.
The corn planting kind of the big fringe of thin planting using paclobutrazol medical fluid handle corn seed, so as to maize seedling strain into
Row control, controls nutrient growth, to inhibit cell elongation, shorten internode, dwarfed plant, promotion seedling is short, seedling is thick, robust seedling, root
It is fine to reach, promote resistance and resistant to lodging.
The four line seeder of a film for planting the corn includes material storing box, and the two sides of the material storing box bottom are fixed to be connected

Promotion maize production is not only improved, and is conducive to increase farmers' income, has accomplished the unification of economic benefit and social benefit, to guarantor
Local the lasting of maize production, stable development are demonstrate,proved, is had important practical significance.In addition seeding machinary is improved, by one
Two row seeder of film is changed to four promoting the circulation of qi suction precise sower of a film, disposable to complete sowing, fertilising, overlay film and earthing.
The present invention will accomplish that kind, density, seeding machinery and the agronomic technique of field management want mutual using the technology
Match, be combined with each other.Science selects anti-fall density-resisting and high-yield kind, determines suitable planting spacing according to breediness and plants close
Degree improves yield potential to give full play to the coordinative role of individual with group.Adhere to that Cultural practice is mating, agricultural machinery agronomy
In conjunction with the comprehensive benefit of performance maximum production advantage and every technology.Field management: utilizing wide-and narrow-row advantage, be leniently advanced into,
It sprays insecticide and is operated with top dressing, wherein in corn growth to 7-9 leaf phase, top dressing is carried out, by fertilizer along maize seedling root
It is sprinkled into, is leniently advanced into, control the angle of plough, so that the soil plowed is predominate, the ditch of maize seedling position is covered, to increase
The drought resisting lodging tolerance of strong corn, and 300ppm paclobutrazol medical fluid is sprayed, 50kg/ mus, increase root layer and radical, promotes
Secondary root growth reduces plant height and fringe position, and stem thickening enhances lodging tolerance, and blade shortens, broadening, thickeies,
Cauline leaf angle becomes smaller, and extends upper part leaf area stationary phase also, improves group's net assimilation rate, increases corn thousand
Substance weight accelerates filling speed, reduces empty bar rate, improves grain number per spike and grain weight, make corn yield increasing 12.27%, in jade
The meter Chang Zhi toy trumpet mouth phase quantitatively sprays paclobutrazol medical fluid according to upgrowth situation, after corn pollination, according to plant height situation
It is leniently advanced into, the cornstalk at 2-3 leaf from top to bottom is folded down, but is not turned off, so that nutrition is transmitted downwards, because reducing
Plant height avoids mutually blocking, ventilation and penetrating light, so that the photosynthesis of lower section is more abundant, while avoiding causing because of plant height
Corn lodging.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
