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 drought-resistant and lodging-resistant cultivation method for double-row narrow-furrow wide-ridge back soil moisture detection sowing of corn. The method comprises the stepsof additionally arranging a soil scraper on a corn sowing machine capable of simultaneously sowing more than two rows of corn in lines: selecting a normal sowing machine with more than two sowing machines for corn in even sowing lines, and adjusting the line spacing to be 0.4 m + 0.8 m, wherein 0.4 m is a narrow line spacing, and 0.8 m is a wide line spacing; emerging: additionally arranging a triangular soil scraper, scraping dry soil layers and previous crop straw residues to the back of a wide ridge, the situation that straw and soil are mixed at a seedling belt, and consequently soil is suspended, refined clean soil with sufficient water content can be formed in narrow-row ditches, and the soil moisture detecting and sowing effects are achieved. In this way, good conditions are created for seed germination, and the emergence rate is guaranteed. The seeds emerge quickly and neatly. The phenomenon that seedlings are big and small is rarely generated, so that corn plants grow neatlyand consistently.

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...
