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

[0023] A method for cultivating corn with film covering on high ridges, comprising the following steps:

[0024] 1) Ridging the field

[0025] The height of the ridge after land preparation is 20cm, forming a trapezoidal ridge with a width of 120cm at the bottom of the ridge and a width of 90cm at the top of the ridge;

[0026] 2) Lamination

[0027] Use a plastic film with a width of 90cm and a thickness of 0.008mm for covering;

[0028] 3) Mechanized seeding and fertilization

[0029] Mechanized soil preparation, sowing, fertilization, seedling belt suppression, the soil bulk density after suppression is 1.25g / cm 3 ; Sowing on the ridge, the row spacing is 30cm;

[0030] 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

[0032] A method for cultivating corn with film covering on high ridges, comprising the following steps:

[0033] 1) Ridging the field

[0034] The height of the ridge after land preparation is 25cm, forming a trapezoidal ridge with a width of 130cm at the bottom of the ridge and a width of 100cm at the top of the ridge;

[0035] 2) Lamination

[0036] Use a plastic film with a width of 100cm and a thickness of 0.008mm for covering;

[0037] 3) Mechanized seeding and fertilization

[0038] Mechanized soil preparation, sowing, fertilization, seedling belt suppression, the soil bulk density after suppression is 1.30g / cm 3 ; Sowing on the ridge, the row spacing is 40cm;

[0039] 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

[0041] A method for cultivating corn with film covering on high ridges, comprising the following steps:

[0042] 1) Ridging the field

[0043] The height of the ridge after land preparation is 22cm, forming a trapezoidal ridge with a width of 125cm at the bottom of the ridge and a width of 95cm at the top of the ridge;

[0044] 2) Lamination

[0045] Use a plastic film with a width of 95cm and a thickness of 0.008mm for covering;

[0046] 3) Mechanized seeding and fertilization

[0047] Mechanized soil preparation, sowing, fertilization, seedling belt suppression, the soil bulk density after suppression is 1.30g / cm 3 ; Sowing on the ridge, the row spacing is 35cm;

[0048] 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 relates to the technical field of corn cultivation. The invention discloses a method for cultivating corn through high-ridge film mulching. The method comprises the following steps: 1) ridge culture field: the ridge height after soil preparation is 20-25 cm, and according to formed ladder-shaped ridges, the ridge bottom width is 120-130 cm, and the ridge top width is 90-100 cm; 2) film mulching: a mulching film with the breadth of 80-100cm and the thickness of 0.008 mm is selected for film mulching; and 3) mechanically sowing and fertilizing: the soil is regularly watered and irrigated, hoeing, insect killing and fertilization are carried out until the corns are mature, the corns are harvested, and therefore, the cultivation of the corns is completed. According to the method, the yield of the corns is greatly increased by changing the planting mode, shrinking ridges and increasing rows and performing film mulching planting.

Description

technical field [0001] The invention relates to the technical field of corn cultivation, in particular to a method for cultivating corn with film covering on high ridges. 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 c...
