Abstract

The invention discloses a corn planting method, which is a '8635-3' equilateral triangle planting mode for corn for short. The planting mode is characterized in that line spacing is 0.86 meter, hole spacing is 0.35 meter, and three seedlings are planted into each hole and are arranged to form an equilateral triangle. The planting mode has the advantages that 1, the border row superiority of plants is played fully by increasing the line spacing, and the growth of the plants is facilitated; 2, due to the increase of the row spacing and the hole spacing, the ventilating and light transmission of the plants are facilitated, and the photosynthesis of the plants is promoted; 3, the three seedlings are planted into each hole, so the group superiority and competition characteristic of the corn are played fully; 4, the capacity of root and stem inverting resistance is improved substantially; 5, the pollination capacity is improved, so that seed kernels are fuller, and the phenomena of barren ear tip and imperfect grains are avoided; and 6, the sowing is accurate, final singling is formed while sowing, and the labor is saved.

Description

Corn 8635-3 gold ancient cooking vessel cropping pattern

Technical field

The invention belongs to a kind of plant cover cultivation methods, be meant the corn planting pattern especially.

Background technology

From the quattrocento middle period, corn has prolonged all the time to attack to go and has broadcast single the planting patterns of staying seedling since China is imported in Latin America into, after having experienced chemical fertilizer, twice revolution of hybrid seed in the eighties of last century later stage, in the last thirty years, output does not have great breakthrough again, and per mu yield is arranged about 500 kilograms and wandered.And traditional cropping pattern needs thinning, promptly takes a lot of work and causes the corn underproduction, and through expert determination, only thinning just makes the corn underproduction 30% spend a large amount of labours again simultaneously, has increased the weight of peasant's labour intensity.The shortcoming of single kind method for planting of traditional narrow row: (1) is unfavorable for that ventilation and penetrating light is ventilative, very easily causes the generation of damage by disease and insect.(2) be unfavorable for farm work management, particularly along with the improving constantly of mechanization degree, it is outstanding that this contradiction shows especially.(3) be unfavorable for the performance of maize population advantage and Competition Characteristics.(4) lodging tolerance is poor.

Summary of the invention

The present invention's purpose is to overcome the above-mentioned deficiency of prior art, provides a kind of corn improved kind of method for planting, and it is beneficial to the ventilative and farm work management of ventilation and penetrating light, and lodging tolerance is strong.

For realizing above-mentioned purpose, the present invention takes following technical scheme: line-spacing adopts 0.86m, and the cave is apart from adopting 0.35m, and every cave is 3 seedlings, and these 3 seedlings are arranged as equilateral triangle.

The present invention takes technique scheme to have following beneficial effect: in present stage, the rational density of corn is 6300/mu, and theoretical calculate data of the present invention are 6645 every mu, i.e. 0.86m * 0.35m=0.301M ²666.7 ÷ 0.301=2215 (cave); 2215 * 3=6645 (), by present seed bud ratio 95% calculate 6645*95%=6313 ().The present invention abbreviates " 8635-3 " golden ancient cooking vessel pattern as, 86 is meant line-spacing that is:, and 35 are meant the cave distance, and 3 are meant a number, Jin Ding: the spread pattern that is meant three corns.From 1988, we probe boldly and attempt the corn planting pattern, how spent time in the rational close planting at corn since two more than ten years, 4800,5000,5600,6000,6300,7200 of mu density etc. have been carried out the long-term experiment contrast, final practice shows, characteristics of the present invention are: the one, and the limit row advantage of plant is given full play in the increasing of line-spacing, less than edge effect, helps the growth of plant.The 2nd, the increasing of line-spacing and cave distance helps the ventilation and penetrating light of plant, has promoted the performance of photosynthesis of plants.Three is community superiority and Competition Characteristics that corn has been given full play in three in a cave, and practice shows adopts this cropping pattern, and single corn can not grown.The 4th, ancient cooking vessel formula plantation has increased substantially that anti-root falls, stem could power.The 5th, improved the pollination ability, make seed fuller, effectively avoided the generation of the flat grain of bald point phenomenon.The 6th, accurate sowing, one broadcasts final singling, saving of labor, laborsaving.Through the practice of groping of more than two decades, we have pushed this technology to field planting from the experiment field.2009 the county promoted 20,000 surplus mu, relate to 17 small towns, nearly 400 administrative villages, effect of increasing production is obvious, amplification is at 30%-80%, and the per mu yield of high yield plot surpasses 2000 jin, works the very big interest of having drawn the chief corn expert of member Mr. Cui Yanhong of corn expert group of the national Ministry of Agriculture and Hebei province Mr. Fu Wanxin, and come the county to investigate this pattern for several times, point out that this is the effective way that increases substantially the corn per unit area yield at present.Also attracted simultaneously the concern of country and local medium, reported one after another.

Embodiment

Below in conjunction with embodiment the present invention is described in detail.

Embodiment:

The present invention be directed to North China and on the south wide geographic area, summer corn cultivation plant protection and the administrative skill of campaign are during enforcement, adopt special-purpose Precision Seeding machine, selected anti-close kind, line-spacing adopts 0.86m, the cave is apart from adopting 0.35m, and every cave is 3 seedlings, and these 3 seedlings are arranged as equilateral triangle.Adopt scientific and reasonable management method and special long-acting special slow release fertilizer, the conditioning agent that adapted is special, inhibitor and chemical control agent.The technology of the present invention in 2010 in Hebei, Shandong, Henan, Jiangsu, Anhui and capital, the signatory technology in Jin Wu province two cities promote nearly over one hundred family of unit, for guaranteeing the popularization success of this pattern, we have write summer corn growth cycle management main points, we find that after deliberation the full phase of a corn growth is divided into nine periods of three growth cycles (vegetative period, pustulation period and maturing stage), according to the growth characteristic of each period, sum up and formulated corresponding management method.

Claims

1. the golden ancient cooking vessel cropping pattern of corn " 8635-3 " is characterized in that: line-spacing adopts 0.86m, and the cave is apart from adopting 0.35m, and every cave is 3 seedlings, and these 3 seedlings are arranged as equilateral triangle.
