Embodiment 1

[0029] The cultivation method for improving the high temperature resistant planting performance of summer maize described in the present embodiment comprises the following steps:

[0030] (1) Sowing time: Since the long-term continuous high temperature is generally concentrated in late July to early August, corn varieties that are not resistant to high temperature can avoid high temperature weather during the flowering and pollination period, and avoid or reduce the damage caused by high temperature. According to the growth period of the selected corn variety, the sowing date can be adjusted and postponed to mid-June to avoid the high-temperature flowering and pollination period;

[0031] After stubble sowing, adopt the planting method of wide and narrow row spacing, control the spacing between large rows to 70cm, and control the spacing between small rows to 50cm;

[0032] (2) Fertilization: It is advisable to use slow and controlled release fertilizers or stable fertilizers ...

Embodiment 2

[0038] The cultivation method for improving the high temperature resistant planting performance of summer maize described in the present embodiment comprises the following steps:

[0039] (1) Sowing time: Since the long-term continuous high temperature is generally concentrated in late July to early August, corn varieties that are not resistant to high temperature can avoid high temperature weather during the flowering and pollination period, and avoid or reduce the damage caused by high temperature. According to the growth period of the selected corn variety, the sowing date can be adjusted and postponed to mid-June to avoid the high-temperature flowering and pollination period;

[0040] After stubble sowing, adopt the planting method of wide and narrow row spacing, control the spacing between large rows to 80cm, and control the spacing between small rows to 30cm;

[0041] (2) Fertilization: It is advisable to use slow and controlled release fertilizers or stable fertilizers ...

Embodiment 3

[0047] The cultivation method for improving the high temperature resistant planting performance of summer maize described in the present embodiment comprises the following steps:

[0048] (1) Sowing period: Since the long-term continuous high temperature is generally concentrated in late July to early August, corn varieties that are not resistant to high temperature can avoid high temperature weather during the flowering and pollination period, and avoid or reduce the damage caused by high temperature. According to the growth period of the selected corn variety, the sowing date can be adjusted and postponed to mid-June to avoid the high-temperature flowering and pollination period;

[0049] After stubble sowing, adopt the planting method of wide and narrow row spacing, control the spacing between large rows to 80cm, and control the spacing between small rows to 40cm;

[0050] (2) Fertilization: It is advisable to use slow and controlled release fertilizers or stable fertilizer...

Abstract

The invention belongs to the technical field of summer corn planting and particularly relates to a cultivation method capable of effectively improving high-temperature-resistant planting performance of summer corn. According to the cultivation method capable of improving high-temperature-resistant planting performance of the summer corn, the planting date is delayed to mid-to-late June, an original common equal-spacing sowing manner is changed into a narrow-spacing and wide-spacing interval planting manner, a chemical control agent is sprayed on leaf surfaces of corn at the big flare stage forexternal regulation, foliage fertilizer is sprayed on leaf surfaces as assistance for regulation after high-temperature damage, under synergistic effect of all the links, the effects of high-temperature stress on the corn planting yield is effectively relieved, and production and yield are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of summer maize planting, and in particular relates to a cultivation method for effectively improving the high-temperature-resistant planting performance of summer maize. Background technique [0002] Corn, also known as maize, cob, corn, etc., belongs to the genus Maize in the Gramineae family. Corn is rich in carbohydrates, protein, vitamins, dietary fiber, minerals and other essential nutrients for the human body, especially it is rich in zeaxanthin, linoleic acid and glutathione. Relevant studies have shown that zeaxanthin is a component of the human retina, linoleic acid is an essential fatty acid required by the human body, glutathione can improve the body's immunity and anti-cancer effects, dietary fiber can delay the rise of blood sugar and clear intestinal waste and other functions. It can be said that the whole body of corn is a treasure, which plays an important role in regulating the abnormal m...
