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 ...
