【Adaptability】

Participated in the 2018-2019 Yunnan Gaokang Agricultural Corn Consortium Middle Altitude Group Test. In 2018, the average yield per mu in the regional test was 715.8 kg, which was an increase of 7.67% compared with the control Haihe No. 2, and the average yield per mu in 2019 was 660.3 kg, which was higher than the control Haihe 2 The yield increased by 15.5%, the average yield per mu in the two-year regional trial was 688.1 kg, an increase of 11.6% over the control, and the average yield per mu in the production test in 2019 was 649.2 kg, an increase of 20.2% over the control. Resistance identification: resistance to gray spot disease, high resistance to large spot disease, resistance to rust, susceptible sheath blight, and resistance to ear rot.

【Main cultivation measures】

1. Sowing date: Spring sowing is based on the stability of the ground temperature above 10°C. The seedlings can be planted in plastic trays or covered with plastic film and can be sowed 5-10 days in advance.

2. Density: about 3200 plants/mu.

3. Bottom fertilizer: 1000-1500 kilograms of manure per mu or more than 50 kilograms of N.P.K ternary compound fertilizer.

4. Seedling fertilizer: apply when 4-5 leaves are visible, apply 10 kg of urea per mu.

5. Ear fertilizer: apply when 10-12 leaves are visible, and apply 20 kg of urea per mu.

6. Grain fertilizer: depending on the growth situation, supplementary grain fertilizer can be applied during the male and silking period, 5kg urea per mu.

7. Management: Seedlings during the 3-leaf period and fixed seedlings at the 4--5 leaf period. After fertilization, timely intertillage, weeding, soil cultivation and fertilization, and prevention and control of corn borer during the big bell-mouth period.

[Suitable area for planting]

It is suitable for planting in corn areas with an altitude of 1000-2000 meters in Yunnan Province.
