Problems solved by technology

[0003] In recent years, because the traditional planting mode (planting on ridges with stubble removal) has not changed for many years, the production mode is extensive, and the average yield of corn is 6500-7500kg / hm 2 , coupled with a series of problems such as low temperature in spring, difficulty in maintaining seedlings due to spring drought, poor crop growth, lodging, premature aging, late maturity and poor seed setting, etc., resulting in unstable yield, poor quality and low benefit of planting corn

Embodiment 1

[0018] The method for cultivating corn in three rows on a ridge comprises the following steps:

[0019] Ladder-shaped ridges formed by ridges after soil preparation, mechanized soil preparation, sowing, fertilization, and suppression of seedling belts. The soil bulk density after compaction is 1.25g / cm 3 ; Sow on the ridge, plant 3 rows in each ridge, and the row spacing is 30cm; the deep loosening width is 80cm, the deep loosening depth is 25cm, and the base of the deep loosening channel forms a rat hole.

[0020] The soil is regularly watered and irrigated, weeded, insecticided and fertilized until the corn is mature and the corn is harvested, that is, the cultivation of the corn is completed.

Embodiment 2

[0022] The method for cultivating corn in three rows on a ridge comprises the following steps:

[0023] Ladder-shaped ridges formed by ridges after soil preparation, mechanized soil preparation, sowing, fertilization, and suppression of seedling belts. The soil bulk density after compaction is 1.30g / cm 3 ; Sow on the ridge, plant 3 rows in each ridge, and the row spacing is 35cm; the deep loosening width is 70cm, the deep loosening depth is 30cm, and the base of the deep loosening channel forms a rat hole.

[0024] The soil is regularly watered and irrigated, weeded, insecticided and fertilized until the corn is mature and the corn is harvested, that is, the cultivation of the corn is completed.

Embodiment 3

[0026] The method for cultivating corn in three rows on a ridge comprises the following steps:

[0027] Ladder-shaped ridges formed by ridges after soil preparation, mechanized soil preparation, sowing, fertilization, and suppression of seedling belts. The soil bulk density after compaction is 1.30g / cm 3 ; Sow on the ridge, plant 3 rows in each ridge, and the row spacing is 30cm; the deep loosening width is 70cm, the deep loosening depth is 30cm, and the base of the deep loosening channel forms a rat hole.

[0028] The soil is regularly watered and irrigated, weeded, insecticided and fertilized until the corn is mature and the corn is harvested, that is, the cultivation of the corn is completed.

Abstract

The invention belongs to the technical field of corn cultivation, and discloses a method for cultivating corn in three rows on a ridge. The method for cultivating corn in three rows on the ridge comprises the following steps: a trapezoidal ridge is formed after soil preparation of the ridge, mechanical soil preparation, sowing, fertilizing and compacting of seedling strips are carried out, wherein the bulk density of the compacted soil is 1.25-1.30 g / cm<3>; sowing is conducted on the ridge, three rows of seeds are planted on each ridge, and the row spacing is 30-35 cm; watering, irrigating, hoeing, pest killing and fertilization are carried out on the soil at regular intervals until the corn is mature, and the corn is harvested to complete the cultivation of the corn. According to the corn cultivation method provided by the invention, the yield of corn is greatly increased by changing a traditional planting mode and reducing ridges and increasing rows.

Description

technical field [0001] The invention relates to the technical field of corn cultivation, in particular to a method for cultivating corn in three rows on a ridge. Background technique [0002] The Northeast Plain is one of the three major black soil belts in the world. The rain and heat in this area are in the same season, and the soil is fertile. It is an important commodity grain base in my country. The corn planting area in this area accounts for more than 70% of the province's main crop planting area, and the per capita grain share and commodity rate both rank first in the country. It is the famous "Golden Corn Belt". The grain production in this region occupies a pivotal position in my country and has made important contributions to ensuring national food security. [0003] In recent years, because the traditional planting mode (planting on ridges with stubble removal) has not changed for many years, the production mode is extensive, and the average yield of corn is 65...
