【Main cultivation measures】
(1) Suitable sowing: The sowing date should be from mid-April to mid-May.
(2) Planting density: The suitable density of medium fertility soil is 3000 plants/mu.
(3) Prevention and control of diseases, insects and weeds: when applying seedling fertilizer and ear fertilizer, weeding with intertillage, attention should be paid to the prevention and control of aphids and corn borer during the large bell mouth stage.
