Abstract

The invention discloses a corn big and small ridge wide planting method. The method comprises the following steps: soil tillage, furrowing, wide seeding on two sides of furrow ridge, and management, wherein the wide seeding on two sides of the furrow ridge is to form two seeding zones on two sides of the furrow ridge 2.5cm away from the furrow ridge; each seeding zone comprises two lines of seeds; the distance between the two lines of seeds is 15cm; the two lines of seeds are distributed in a staggered way; the vertical distance between each two adjacent holes of seeds is a planned planting distance, so that the method is beneficial to nutrient balanced application and the absorption of corn, and good interplanting ventilation and light-admitting quality can effectively prevent lodging. As furrowed field planting is adopted, the method is beneficial to irrigation and drainage, can effectively increase the corn yield, and is particularly applicable to pure corn planting.

Description

Corn size row spacing width of cloth implantation methods

Technical field:

The present invention relates to a kind of method of corn planting sowing, this invention belongs to the arviculture technical field, is applicable to the corn size row spacing width of cloth implantation methods of the pure corn planting of corn-growing regions.

Background technology:

Traditional spring corn implantation methods is line-spacing or the plantations of size row such as level land, seed is the planting type that strip distributes, because the level land is bedder-planter not, the evaporation from topsoil speed of crop, irrigation and drainage comfort level, root growth, lodging tolerance all are very limited, and the seed strip distributes, ventilation and pollination machine can all be in and be unfavorable for the corn growth aspect between corn field, cause traditional implantation methods output lower, this mode can cause again the problems such as ventilation and penetrating light is poor, easy lodging as increasing the planting density of corn.

Summary of the invention:

Purpose of the present invention just provides the corn size row spacing width of cloth implantation methods of a kind of irrigation and drainage convenience, drought resisting, resistant to lodging, ventilation and penetrating light, well developed root system, to improve corn yield.

The object of the present invention is achieved like this: a kind of corn size row spacing width of cloth implantation methods, it may further comprise the steps: whole ground, do furrow, the wide cut sowing of furrow stalk both sides, management, it is characterized in that the both sides wide cut sowing of described furrow stalk is achieved in that on the basis of leveling land wholely, machinery is done furrow, furrow face width 110cm, furrow obstruct wide 30cm, respectively sowing a seeding belt from furrow stalk 2.5cm both sides, a seeding belt is comprised of two row seeds, two row seeds are apart from 15cm, two row seeds are interspersed, and the vertical range of two adjacent cave seeds is exactly the spacing in the rows of plan.

The present invention compared with prior art has the following advantages:

The beneficial effect that adopts technique scheme to produce is: owing to adopt the both sides wide cut sowing of every furrow stalk, every side seed is zonal distribution, is conducive to the nutrient equilibrium and uses and Maize Absorption, and ventilation and penetrating light is better between strain, can effectively prevent lodging; Owing to adopt the embanked field plantation, be conducive to irrigation and drainage, can effectively increase corn yield.

This implantation methods was through test in 3 years, and rate of growth can reach more than 10%.

Embodiment:

The present invention includes following steps:

1, wholely: lower base fertilizer is executed in deep ploughing, executes organic barnyard manure 2000kg for every mu, potassium sulphate 25kg, phosphoric acid diamines 30kg;

2, seed and processing: select the anti-close type kind of high yield, the corn seed of selected full seed is dressed seed when skilful and suitable happy with height, with control small brown rice planthopper in seedling stage, aphid, rough dwarf disease, head smut and banded sclerotial blight etc.;

3, do furrow: furrow obstruct wide 30cm, furrow face width 110cm;

4, sowing: respectively sowing a seeding belt from furrow stalk 2.5cm both sides, a seeding belt is comprised of two row seeds, and two row seeds are apart from 15cm, and two row seeds are interspersed, and the vertical range of two adjacent cave seeds is exactly the spacing in the rows of plan, broadcasts about 5000 caves for every mu;

5, fertilising: the shooting stage topdress potassium sulphate 25kg, urea 10kg; The typhon mouth phase urea 25kg that topdresses, the loose powder phase urea 10kg that topdresses;

6, management: after (1) emergence of corn, look into immediately seedling, fill the gaps with seedlings, thinning during general 2 expansion leaves, final singling when the 3-4 sheet launches leaf; (2) carry out 2-3 intertillage, seedling is short and small before the final singling, will avoid pressing seedling during intertillage; (3) carry out chemical weed control and intertill and clean tillage, weed killer herbicide will be strictly selected in chemical weed control, accurately controls consumption, and corn 3-5 leaf adopts 50% acetochlor ec 80-100ml/ mu to be watered 40--50kg during the phase, sprays earth's surface in the ranks; (4) in time prevent and treat rough dwarf disease, before emerging, carry out chemical control, can prevent and treat with the 10 gram sprayings of 10% Imidacloprid by mu; After the emergence of corn, in corn three, four leaf phases, to spraying medicine control small brown rice planthopper around field and the plot, medicament can with 40% omethoate emulsifiable solution l000 times liquid or 10% Imidacloprid 15g, be watered the spraying of 30-40 kilogram.

Claims

1. corn size row spacing width of cloth implantation methods, it may further comprise the steps: whole ground, do furrow, the wide cut sowing of furrow stalk both sides, management, it is characterized in that the both sides wide cut sowing of described furrow stalk is achieved in that on the basis of leveling land wholely, machinery is done furrow, furrow face width 110cm, furrow obstruct wide 30cm, respectively sowing a seeding belt from furrow stalk 2.5cm both sides, a seeding belt is comprised of two row seeds, two row seeds are apart from 15cm, two row seeds are interspersed, and the vertical range of two adjacent cave seeds is exactly the spacing in the rows of plan.
