Deng Mai 996

Dengmai 996 was selected from the variant line of Zhoumai 11 by Henan Xiantian seed Industry Co., Ltd. the approval number is Yu Xianmai 2007008.

The growth period of the weak spring precocious variety was about 204 days, which was the same as that of the control Yumai 18. The seedling is semi-erect, the cold resistance is strong, the tillering ability is medium and the panicle rate is high. The plant height is 84 cm, the stem is elastic and resistant to lodging. The plant type is compact, the flag leaf is lifted up, the ear layer is neat, and the maturity and yellowing is good. The spike is fusiform, with long awn and white grains. The grain is half-horny, full, high bulk density and low black embryo rate. The three factors of yield were coordinated, the number of ears per mu was 397600, the number of grains per ear was 38.8g, and the weight of 1000 grains was 39.4g.

From 2006 to 2007, the average yield per mu was 476.4 kg, 7.5% higher than that of Yumai 18, the average yield per mu was 476.4 kg.

Resistance identification is resistant to leaf blight, stripe rust, leaf rust, powdery mildew and sheath blight.

The key points of cultivation are suitable to be planted in the double cropping area of rice and wheat in the south of our province. The suitable sowing time is from October 15 to 28. The suitable sowing rate of high fertility plots is 89kg per mu, and the sowing rate of medium and low fertility plots can be increased appropriately, such as delayed sowing, it is appropriate to increase the sowing rate of 0.5kg per mu every 3 days. Apply sufficient base fertilizer, weed in time before returning to green, and pay attention to the prevention and control of diseases and insect pests. From heading to filling stage, potassium dihydrogen phosphate solution was sprayed in time to make the grains large and full.
