Abstract

The invention discloses a rapid corn cultivation technology. The rapid corn cultivation technology includes the steps of artificial sprouting, namely soaking corn seeds in water for 20-24 hours, sprouting the seeds for 18-20 hours under the temperature ranging from 28 DEG C to 30 DEG C and sowing the seeds when radicles grow by 1-2mm; excavating sowing ditches, namely spraying proper water in ditches before transplanting seedlings, evenly transplanting the seedlings in the sowing ditches, and covering the surfaces of the seedlings with a thin film layer; covering bud seedling roots with soil, namely backfilling smashed wheat straws beside the roots; adopting quick-acting nitrorgenous fertilizer after a jointing stage of corns reaches a tasseling stage, and then spraying weed killer on the land surface; pushing aside subtending leaves for airing after 35-50 days of laddering of the corns, irrigating along with releasing long-term compound fertilizer after the corns enter a vigorous growth period and harvesting in 1-2 months. Budding time is shortened and budding rate is high by artificial sprouting, the seedlings are directly transplanted to the soil after growing up, the smashed wheat straws are backfilled beside the roots to provide natural nutrients, the sufficient irrigation is performed, and high yield of the corns can be achieved.

Description

Maize culture technique fast

Technical field

The present invention relates to a kind of maize culture technique, relate in particular to a kind of maize culture technique fast.

Background technology

Corn is annual gramineae herbaceous plant, is important cereal crops and important feed resource, is also the highest cereal crops of whole world gross yield, and corn growing season is shorter, requires warm rainy in vegetative period.In the whole growth cycle of corn, the most important thing is to ensure bud ratio, reduce the death of rice shoot.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.

Summary of the invention

For addressing the above problem, the invention provides the quick maize culture technique that a kind of bud ratio is high.

The technical solution used in the present invention:

Maize culture technique fast, comprises the following steps:

A, artificial germination, be placed on corn seed in water and soak 20-24 hour, is placed in vernalization 18-20 hour under the condition of 28-30 DEG C, in the time that radicle grows 1-2 millimeter, waits to sow;

B, excavation seed furrow, dark 5-8 centimetre sprays appropriate water before transplanting bud seedling in ditch, evenly transplants bud seedling in seed furrow, covers thin film on bud seedling surface;

C, place of bud shoot root portion cover upper soil, irrigate every the dusk of 2-3 days, and while waiting seedling to grow to 15-20 centimetre, the wheat stalk of pulverizing at root side landfill;

D, corn jointing, to tasseling stage, adopt available nitrogen fertilizer, apply, then at earth's surface spraying herbicide in conjunction with trenching ridging;

After 35-50 after e, corn reel off raw silk from cocoons days, take off bract airing, corn entered after vigorous vegetative period, every 5-7 days, watered, and squeezed into slow release long-acting composite fertilizer in the water of pouring, after 1-2 month, can gather in.

Take off bract airing and be specially bract is torn to little openning, expose iblet, be fully exposed to the sun under the sun.

Advantage of the present invention is: artificial germination, and shorten and sprout the time, bud ratio is high, is grafted directly in soil after waiting bud seedling to grow up, and the wheat stalk of pulverizing at root side landfill, provides natural nutrient, waters sufficient moisture, corn with high yield.

Embodiment

Following embodiment is only for the present invention is described, but can not limit protection scope of the present invention.

Embodiment 1

Maize culture technique fast, comprises the following steps:

A, artificial germination, be placed on corn seed in water and soak 20 hours, is placed under the condition of 28 DEG C vernalization 18 hours, in the time that radicle grows 1 millimeter, waits to sow;

B, excavation seed furrow, dark 5 centimetres, before transplanting bud seedling, in ditch, spray appropriate water, in seed furrow, evenly transplant bud seedling, cover thin film on bud seedling surface;

C, place of bud shoot root portion cover upper soil, irrigate every the dusk of 2 days, and while waiting seedling to grow to 15 centimetres, the wheat stalk of pulverizing at root side landfill;

D, corn jointing, to tasseling stage, adopt available nitrogen fertilizer, apply, then at earth's surface spraying herbicide in conjunction with trenching ridging;

After 35 days after e, corn reel off raw silk from cocoons, take off bract airing, corn entered after vigorous vegetative period, every 5 days, watered, and squeezed into slow release long-acting composite fertilizer in the water of pouring, after 1 month, can gather in.

Take off bract airing and be specially bract is torn to little openning, expose iblet, be fully exposed to the sun under the sun.

Embodiment 2

Maize culture technique fast, comprises the following steps:

A, artificial germination, be placed on corn seed in water and soak 22 hours, is placed under the condition of 29 DEG C vernalization 19 hours, in the time that radicle grows 1.5 millimeters, waits to sow;
