In 1998 and 1999, he participated in the National Winter trial of the Upper reaches of the Yangtze River. In 1998, 22 pilot projects were conducted, in which the yield increased at 20:00 and decreased at 2 o'clock, with an average yield of 304.5 kg per mu, 17.79% higher than that of Mianyang 20%. Among them, the yield was increased at 16:00 and decreased at 4 o'clock, with an average yield of 2855 kg per mu, 9.17% higher than that of Mianyang 20. It also participated in the production experiment in 1999, increasing production at 6 points and reducing yield at 3 points, with an average yield of 269.3 kg per mu, an increase of 1.27% over Mianyang 20.

Key points of cultivation: the suitable sowing time is from Frosts Descent to the Beginning of Winter, and the sowing rate is controlled at 14,000,180,000 / mu basic seedlings according to fertility conditions. About 10 kg of pure nitrogen per mu, combined use of phosphorus and potassium fertilizer, heavy application of base fertilizer, early application of seedling fertilizer. In the fields with high fertility and high density, dwarf element was applied at the beginning of the technical festival. Pay attention to the control of aphids at heading and flowering stage. The plant is on the high side, so pay attention to prevent lodging during cultivation.

Suitable scope: 300 kilograms of middle and high water and fertilizer land in the winter wheat area of the upper reaches of the Yangtze River. Is a weak variety, flour is suitable for making biscuits, cakes and other food.
