Problems solved by technology

Corn is a tall crop, and large-scale planting will cause mutual shading, resulting in poor ventilation and light transmission in the middle and lower leaves of the corn, reducing the photosynthetic rate of the corn, resulting in empty stalks and lodging of the corn, seriously reducing production

Embodiment Construction

[0032] The following examples describe the present invention in more detail:

[0033] 1. In order to improve the spring drought resistance and preserve seedlings of corn seedlings.

[0034] In order to adapt to the condition that the machine-sown corn seedlings can resist spring drought and preserve the seedlings under the condition of all being fed by rain, the "corn strip field with wide and narrow rows alternately diverted cultivation mode" is proposed. Technical points:

[0035] 1. Carry out "strip field restructuring" on the traditional ridge-planting and ridge-management cornfields; the reformation plan is to perform rotary tillage on the traditional ridge-planting cornfields and ridges in autumn. Before sowing in spring (on the day of sowing), first use V-shaped pull Two ridges and one combination are used to scoop up the land. It is required to fish the air-dried soil on the two ridges into the furrow in the middle of the two ridges, so that the surface of the two rid...

Abstract

The invention provides a method for cultivating double wide-narrow bushes by alternatively changing wide rows and narrow rows of a corn strip field in a quantified and positioned manner. The method carries out rotary tillage and autumn ridging on a traditional ridging corn field; before the day of sowing in spring or in the day of sowing, a V-shaped rock to carry out two ridge and one combination to bail lands; bailing air dried soil on two ridges into an earth furrow between two ridges to form a whole flat level strip field by ridge surfaces of the two ridges and the earth furrow in the middle; the process of sowing utilizes a primary double-row spacing and narrow-row spacing of the wide rows and narrow rows to sow so that two rows of corn seeds on the strip field are rightly sowed on a corn unoccupied area to be planted in the soil of a plane wet strip field without fore-rotating crop corn stubbles. The method provided by the invention can improve capabilities of resisting spring drought and preserving seedlings at a seedling stage of corns. By utilizing the method, high-light effect ventilation and light transmission of corns are improved, empty sticks are reduced, lodging is resisted, and yield and income are increased.

Description

technical field [0001] The invention relates to a method for cultivating crops, in particular to a method for cultivating corn. Background technique [0002] In the northern part of our country, there are nine droughts in ten springs. When there is a severe drought in spring, it is difficult to ensure full seedlings for corn sowing. Corn is a tall crop, and large-scale planting will cause mutual shading, resulting in poor ventilation and light transmission in the middle and lower leaves of corn, reducing the photosynthetic rate of corn, resulting in empty stalks and lodging of corn, seriously reducing production. Contents of the invention [0003] The object of the present invention is to provide a method for quantitatively positioning double-plant wide-narrow cluster cultivation method that can increase corn yield by alternating wide and narrow rows in a corn strip field. [0004] The purpose of the present invention is achieved like this: [0005] For the traditional r...
