specific Embodiment approach 1

[0023] Specific implementation mode one: combine figure 1 Describe this embodiment mode, a kind of corn single ridge double-row staggered dense planting method described in this embodiment mode, described method is realized according to the following steps:

[0024] Step 1: In the spring of the first year, carry out subsoiling, rotary tillage, leveling, and fertilization, and use a ridging machine to pre-treat the planting site so that the planting site is a planting site where ridges and ridges alternate. The cross-section of each ridge It is trapezoidal, and the cross-section of each furrow is trapezoidal; a tractor driving ramp needs to be reserved in the middle of every two ridges, and a four-row seeder is used, and each two groups of sowing units are adjusted to the specified distance, and the distance between the two groups of units is the ridge distance , two rows of planting lines are set along the length of the ridge, and each row of planting lines is planted with cor...

specific Embodiment approach 2

[0031] Specific implementation mode two: combination figure 1 and figure 2 This embodiment is described. The method for staggered and dense planting of corn in a single ridge and double rows described in this embodiment, in step 1, the distance between two adjacent ridges is L, and the value of L is 650mm. Other methods are the same as in the first embodiment.

specific Embodiment approach 3

[0032] Specific implementation mode three: combination figure 1 and figure 2 This embodiment is described. The method for staggered and dense planting of corn in a single ridge and double rows described in this embodiment, in step 2, the distance between the two rows of planting lines on each ridge is d, and the value of d is 200mm. Other methods are the same as in the first embodiment.

Abstract

The invention discloses a single-ridge double-row staggered close planting method for corn. The method aims at solving the problems that an existing northeast corn planting mode is unreasonable, and the yield cannot be continuously increased. The corn single-ridge double-row staggered close planting method comprises the following steps that 1, deep scarification, rotary tillage, land leveling andfertilization are carried out in spring of the first year, earlier-stage treatment is carried out on a planting field by using a ridger, and every three adjacent holes for planting the corn are distributed in an isosceles triangle shape; 2, the corn is planted on two rows of planting lines of a ridge table in the planting process due to no-tillage treatment of the soil in the previous year; 3, forcorn rootstalk treatment in the first year and the second year, no-tillage sowing is carried out on the planting position of the first year in spring in the third year; 4, for corn rootstalk treatment in the previous year, no-tillage sowing is carried out on the planting position of the second year in spring, and straw with rootstalk and the rootstalk on all ridges are returned to the field afterharvest in autumn; and 5, cyclic sowing is carried out according to the steps 1-4 in the next cycle period. The method is applied to the field of agricultural planting.

Description

technical field [0001] The invention relates to a method for planting corn, in particular to a single-ridge double-row staggered dense planting method for corn, and the invention belongs to the field of agronomy. Background technique [0002] Food is the foundation of human survival and development, and the cornerstone of social stability. The black soil region in Northeast China is particularly important to national food security. The most direct way to ensure national food security is to increase grain production. There are many ways to increase production. Various technologies such as genetically modified corn are applied, but now there is a problem that the production cannot continue to be increased. Therefore, the most direct and effective way to increase production is dense planting . [0003] Blind farming will cause great damage to the black soil, which will directly lead to problems such as soil erosion and soil fertility decline, and then indirectly affect the yie...
