[Adaptability]:

The average yield per mu in the two-year regional test was 653.15 kg, which was 6.04% higher than the control Huayu 11. Among them, the average yield per mu in 2018 was 610.40 kg, which was 5.18% higher than that of Huayu 11; the average yield per mu in 2019 was 695.89 kg, which was 6.80% higher than that of Huayu 11. Field large spot disease is grade 5, small spot disease is grade 5, gray spot disease is grade 5, ear rot is grade 3, rust disease is grade 3, and grade 9 sheath blight disease plant rate is 0.2%, and stem rot disease plant rate is 0.8%. The field lodging (discount) rate is 1.2%.

[Main cultivation measures]:

1. Plant seeds at the right time and plant them closely. Sowing in early and mid-April, about 3000 plants per mu for single cropping. 2. Scientific use of fertilizer. Apply plantar fertilizer, lightly apply seedling fertilizer, and watch seedling application ear fertilizer. 3. Strengthen field management. Pay attention to squatting seedlings, timely cultivating and weeding, drought resistance, drainage, and prevention of lodging. 4. Prevent pests and diseases. Pay attention to the prevention and control of large spot disease, small spot disease, gray spot disease, ear rot, rust, sheath blight, stem rot and cutworm, black stink bug, armyworm, armyworm, corn borer and other diseases and insect pests.

[Suitable area for planting]:

It is suitable for planting spring maize in areas with an altitude of 500-1200 meters in Hubei Province.
