TECHNICAL FIELD

[0001] The application belongs to the technical field of bio-agriculture, and particularly relates to a high-SOD-content crop cultivation method. BACKGROUND

[0002] SOD is a natural enemy of oxygen free radicals and a No. 1 killer of oxygen free radicals in the body, and the level of SOD in the body is an intuitive indicator of aging and death; appropriate intake of SOD is very beneficial to human health; at present, some health products on the market increase the activity of SOD by adding SOD extract, but the cost of SOD extract is high and needs to be stored at low temperature, which makes the health products more expensive.

[0003] Sugarcane naturally contains a certain amount of SOD active enzyme, but the natural SOD active enzyme content in sugarcane is low, so the effect on the human body is very small. SUMMARY

[0004] In view of the above situation, in order to overcome the defects of the prior art, the application provides a cultivation method, which increases the absorption effect of the root of sugarcane on the fertilizer in the soil by applying specific fertilizer multiple times in the growth cycle of sugarcane and adopting the mode of intercropping sugarcane and rhizoma dioscoreae, so as to promote the generation of high-content SOD active enzyme in the interior of sugarcane.
