[Main traits of varieties]:
The plant is semi-compact, with high plant and ear positions. The leaf sheath of the seedling is purple, the number of adult leaves is about 20, and there are about 6 leaves on the panicle. The tassels have 8 to 17 branches, the anthers are light red, and the filaments are light red. The ears are tube-shaped, the bracts are relatively intact, the cob is white, the grains are yellow, and the dentate. In the regional test, the plant height is 298.9 cm, the ear height is 135.1 cm, the empty stalk rate is 1.0%, the ear length is 18.7 cm, the ear thickness is 5.8 cm, the bald tip length is 1.0 cm, the number of ear rows is 19.5, the number of rows is 36.7, and the thousand-grain weight is 341.7 grams. The seed yield rate from dry ears was 86.5%, and the growth period was 130.9 days. The quality is determined by the Cereal Quality Supervision, Inspection and Testing Center of the Ministry of Agriculture. The bulk weight is 736 g/L, the crude protein (dry basis) content is 9.63%, the crude fat (dry basis) content is 4.85%, and the crude starch (dry basis) content is 71.48%.
[Adaptability]:
From 2016 to 2017, we participated in the regional test of maize mountain group varieties in Hubei Province. The average yield per mu in the two-year regional test was 687.76 kg, which was 8.98% higher than the control Shuangyu 919. Among them, the yield per mu in 2016 was 677.90 kg, which was 6.48% higher than that of Shuangyu 919; the yield per mu in 2017 was 697.62 kg, which was 11.53% higher than that of Shuangyu 919. Field gray spot disease was grade 5, ear rot was grade 3, sheath blight was grade 9 diseased plants rate was 1.1%, and stem rot diseased plants rate was 1.4%. The field lodging (discount) rate was 2.3%.
[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 fertilization. Apply plantar fertilizer, lightly apply seedling fertilizer, and watch seedling topdressing ear fertilizer.
3. Strengthen field management. Pay attention to squatting seedlings, timely cultivating, drought resistance and drainage, and prevention of lodging.
4. Prevent pests and diseases. Pay attention to the prevention and control of gray spot, ear rot, stem rot, cutworm, corn borer and other diseases and insect pests.
[Suitable area for planting]:
It is suitable for planting spring maize in low mountains and two high mountains below 1000 meters above sea level in Hubei Province. Introduced in Hunan Province. Corn plants are planted in ten prefectures of Zhaotong City, Kunming City, Lijiang City, Dehong Prefecture, Qujing City, Chuxiong Prefecture, Dali Prefecture, Baoshan City, Lincang City, and Pu'er City in the altitude of 1,000 to 2,000 meters. It is planted in corn areas with an altitude of 1000-2000 meters in Yuxi City, Honghe Prefecture, and Wenshan Prefecture.
