Problems solved by technology

[0004] Increasing the planting density of corn is an important technical measure to increase the yield of corn, but after the planting density increases, the root development of corn will be restricted, which increases the risk of root lodging in the later stage

Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] see Figure 1~2 , in an embodiment of the present invention, a double-row narrow ditch wide ridge back soil moisture detection sowing method for drought-resistant and lodging-resistant corn comprises the following steps:

[0026] 1) Install a soil scraper on a corn seeder that can drill more than 2 rows at the same time: select a normal seeder with more than 2 seeders that is an even row of corn, and adjust the row spacing to 0.4m+0.8m; 0.4m is the nar...

Abstract

The invention discloses a double-row, narrow-ditch, wide-ridge, back-moisture-seeding, drought-resistant and lodging-resistant cultivation method for corn. A soil scraper is installed on a corn seeder capable of drill-sowing more than two rows at the same time: the one with more than two seeders is selected as an even-numbered seeder. For the normal seeder of row corn, adjust the row spacing to 0.4m+0.8m; The straw residue is scraped on the back of the wide ridge to avoid the mixing of straw and soil at the seedling belt, so that the soil is suspended, and the narrow row ditch can become fine and clean soil with sufficient water content, which can play the role of moisture detection and sowing. This creates good conditions for seed germination and ensures the emergence rate. Make the seeds emerge quickly and neatly. The phenomenon of large and small seedlings rarely occurs, so that the corn plants develop neatly and uniformly.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a drought-resistant and lodging-resistant cultivation method for corn with double rows, narrow furrows, wide ridges and back moisture detection sowing. Background technique [0002] The area of ​​cultivated land in Shanxi Province is 4,803,647 hectares, among the existing cultivated land, the area of ​​dry land reaches 3,816,266 hectares, accounting for nearly 80% of the total cultivated land area of ​​the province. Among them, the area of ​​sloping cultivated land in Shanxi Province reached 1,666,200 hectares, accounting for 44% of the total area of ​​dry land in the province. More than 50% of the dry land and sloping land are planted with maize. In the case of nine droughts in ten years in spring, the lack of moisture due to drought, previous stubble stalks, and soil suspension caused the emergence rate of corn to be low, resulting in serious lack of seedlings an...
