Embodiment 1

[0023] A method for high-yield and stress-resistant corn covered with plastic film in cold regions, comprising the following steps:

[0024] S1. Before freezing in autumn, choose a plot with flat terrain, good water and fertilizer retention performance, deep plowing layer, and convenient drainage and irrigation. Deep plow 33cm, and then press 12t / hm 2 Evenly spread the amount of decomposed organic fertilizer, and plow once again, with a depth of 15cm;

[0025] Among them, the land is the land where soybeans or corn were planted in the previous stubble, so as to realize crop rotation and promote the increase of corn production.

[0026] S2, in the spring of the second year, level and rake finely and form a ridge with a ridge width of 120cm, according to 400kg / hm 2 Spread the base fertilizer evenly, spray the herbicide (Acetrexate, the dosage is 50% of the conventional non-mulching dosage), cover the plastic film, set the surrounding of the plastic film in furrows and compact i...

Embodiment 2

[0033] A method for high-yield and stress-resistant corn covered with plastic film in cold regions, comprising the following steps:

[0034] S1. Before freezing in autumn, choose a plot with flat terrain, good water and fertilizer retention performance, deep plowing layer, and convenient drainage and irrigation. Deep plow 30cm, and then press 10t / hm 2 Evenly spread the amount of decomposed organic fertilizer, and plow once again, with a depth of 10cm;

[0035] Among them, the land is the land where soybeans or corn were planted in the previous stubble, so as to realize crop rotation and promote the increase of corn production.

[0036] S2, in the spring of the second year, level and rake finely and form a ridge with a ridge width of 110cm, according to 400kg / hm 2 Spread the base fertilizer evenly, spray the herbicide (the amount of octyl, the dosage is 50% of the conventional non-mulching amount), cover the plastic film, set the surrounding of the plastic film in the furrow a...

Embodiment 3

[0043] A method for high-yield and stress-resistant corn covered with plastic film in cold regions, comprising the following steps:

[0044] S1. Before freezing in autumn, choose a plot with flat terrain, good water and fertilizer retention performance, deep plowing layer, and convenient drainage and irrigation. Deep plow 40cm, and then press 14t / hm 2 Evenly spread the amount of decomposed organic fertilizer, and plow once again, with a depth of 20cm;

[0045] Among them, the land is the land where soybeans or corn were planted in the previous stubble, so as to realize crop rotation and promote the increase of corn production.

[0046] S2, in the spring of the second year, level and rake finely and form a ridge with a ridge width of 130cm, according to 400kg / hm2 Spread the base fertilizer evenly, spray the herbicide (Acetrexate, the dosage is 50% of the conventional non-mulching dosage), cover the plastic film, set the surrounding of the plastic film in furrows and compact it ...

Abstract

The invention belongs to the technical field of crop cultivation, and in particular relates to a method for high-yield and stress-resistant corn covered with plastic film in cold regions, which comprises the following steps: before freezing in autumn, select a plot with flat terrain and convenient irrigation and drainage for deep plowing, evenly spread decomposed organic fertilizer, and then Plowing once; leveling, raking and forming ridges, spreading base fertilizer, spraying herbicides, and covering with plastic film, when the average ground temperature of 10cm of the plow layer is stable at 10-12°C, sow the pretreated corn seeds on the ridges Apply stress-resistant fertilizers to the roots of corn after germination; topdressing in the mid-jointing stage, watering after jointing to the big trumpet stage, and emasculation in the later stage. According to the environmental characteristics of corn in cold regions and combined with the plastic film cultivation method, the invention prepares stress-resistant fertilizers to achieve the purpose of stress-resistant and high-yield corn in cold regions.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a stress-resistant and high-yield planting method for corn in cold regions covered by plastic film. Background technique [0002] Corn (scientific name: Zea mays), China's largest food crop, in the biological range, corn is a carbon 4 plant, but the bracts use C3 mode for photosynthesis, which is a monoecious plant. The main producing area is located in the third largest corn belt in the world - China's Songliao Plain corn belt. The total planting area of ​​corn is about 1249.35 square kilometers, also known as maize, corn (corn stick), corn, cob, and mallet. Chaoshan dialect is called Youmeiren (because it was introduced from America), Cantonese is called corn, and Hokkien is called Fanmai. It is an annual grass herb, an important food crop and an important source of feed. It is rich in nutrition and is also the food crop with the highest total output in t...
