Plant height about 80 cm, plant type moderate tightness, flag leaves slightly larger, yellow green leaves, waxy, thick culms. Spikelets spindle, spikelets closely arranged, long awn, white shell, white grain, full grain, horny. The average number of ears per mu is 388,000, the number of grains per ear is 36.0, and the 1000-grain weight is 42.9 g. Yellow is better. Cold resistance identification: cold resistance medium. Identification of disease resistance: moderate resistance to leaf rust, sheath blight, high susceptibility to stripe rust, powdery mildew, stem rust. Mixed samples were measured in 2005 and 2006 respectively: Bulk density 798 g/L, 794 g/L, protein (dry basis) content 14.36%, 14.63%, wet gluten content 33.9%, 34.3%, sedimentation value 37.0 ml, 37.3 ml, water absorption 66.6%, 65.9%, stability time 3.6 minutes, 3.4 minutes, maximum extension resistance 198 E. U, 250 E. U, tensile area 50 cm2, 64 cm2.
Yield performance: In 2004~2005, the average yield per mu was 509.7 kg, which was 3.79% higher than that of control Shi 4185. In 2005~2006, the average yield per mu was 536.4 kg, which was 7.82% higher than that of control Shi 4185. The average yield per mu was 576.9 kg in 2006~2007, which was 4.64% higher than that of CK Shi 4185.
Key points of cultivation technology: suitable sowing time is early and middle October, suitable for 100,000 ~ 150,000 seedlings per mu, pay attention to stripe rust, powdery mildew and stem rust in later stage.

Sulfonylureas: chlorsulfuron + dicamba (chlorsulfuron + paracetamol)
Herbicidal characteristics Chlorsulfuron can be absorbed by the roots, stems and leaves of weeds. It is used to control a variety of annual broad-leaved weeds and some grass weeds. It has a long duration in soil. Dicamba can be absorbed by weed stems and leaves and can control a variety of broadleaf weeds. Chlorsulfuron and dicamba have different action mechanisms, and their weed control spectrum is complementary. Mixed use of chlorsulfuron and dicamba can enlarge weed control spectrum and improve weed control effect. Chlorsulfuron + dicamba 0.6g/mu +2 - 3g/mu (active ingredient). suitable for use as
