Check and approve the situation. Beijing examines wheat 2003003.
The characteristics are winter and medium maturity. The seedlings are semi-erect, the leaves are dark green, and the tillering ability and panicle rate are moderate. Spindles, long awn, white shell, red grain. The plant is luxuriant, the plant height is 80 ~ 85 cm. The number of ears per mu is 428000, the number of grains per ear is 29.3, and the weight of 1000 grains is about 40 grams. The lodging resistance is good, the cold resistance is strong. The results of our unit quality analysis are as follows: in 2001, moisture 11.2%, protein content 13.1%, wet gluten content 40.7%, sedimentation value 33.4ml, dough stability time 4.5min; 2002, moisture 11.3%, protein content 13.6%, wet gluten content 39.8%, sedimentation value 31.2ml, dough stability time 3.5min.
The yield showed that in 2000-2001 and 2001-2002, the average yield per mu was 406.1 kg, which was 1% higher than that of the control Jing411.
Main points of cultivation: 1. The suitable sowing date in Beijing is from September 25 to October 5, and the suitable basic seedling is 15-250000 / mu. 2. Scientific fertilization: diammonium phosphate 15kg / mu and urea 15kg / mu are suitable for base fertilizer, returning green fertilizer can be applied properly according to seedling condition and soil fertility, and urea 10-15kg / mu for jointing fertilizer. 3. Rational irrigation: ensure the timely irrigation of "soil moisture water", "frozen water", "saving water" and "grouting water".
The suitable area is suitable for planting in the wheat area with middle and upper soil fertility in Beijing area.
