1. Introduction of Wheat Variety Xinong 979
1, source
Xinong 979 was bred in11as female parent and F 1 as male parent in the wheat breeding laboratory of Northwest A&F University.
2. Growth cycle
The growth period is about 238 days, and the maturity of Xiao Yanyan 22 is 2-3 days earlier, with outstanding early maturity.
3. Characteristics of stems, leaves, spikes and grains
The seedlings are slightly creeping, with dark green leaves, long and narrow flag leaves, compact plant type, good plant type structure, hard stems and good elasticity, and the plant height is about 75-78cm. The panicle type is medium and large, the panicle layer is uniform, the panicle is nearly rectangular, medium and large, and the size is uniform. The awn is long, the shell is white, bright, the grain is big and full, the skin is thin and bright, the embryo rate is low and the commodity is good.
Step 4 output
The average yield per mu in 2004 and 2005 was 536.8 kg and 482.2 kg respectively.
Step 5 resist
Good cold and frost resistance, strong lodging resistance. Good comprehensive disease resistance in the field and good yellowing when mature.
6. Suitable planting area
Xinong 979 is suitable for planting in central and northern Henan Province, northern Anhui Province, northern Jiangsu Province, Guanzhong area of Shaanxi Province and southwestern Shandong Province.
Second, the planting points of Xinong 979
1. Apply sufficient base fertilizer before sowing.
Before planting, base fertilizer should be arranged according to soil fertility. Generally, organic fertilizer and inorganic fertilizer should be matched, and the amount of nitrogen fertilizer should account for 70% ~ 75% of the total amount of nitrogen fertilizer in the whole growth period. After soil preparation and deep ploughing, base fertilizer can be added to meet its growth needs.
2, master the appropriate sowing date and sowing amount.
The suitable sowing date of this variety is 65438+1early October, and the sowing amount per mu is 12- 16 kg. Specifically, the sowing amount should be determined according to factors such as sowing methods and soil conditions. Early sowing is easy to bolting, and late sowing is difficult to overwinter smoothly.
3, do a good job of winter irrigation
Watering according to the growth situation, topdressing nitrogen fertilizer in time during winter irrigation, and the amount of nitrogen fertilizer should account for 25% ~ 30% of the whole growth period. The remaining nitrogen fertilizer is used for heading and filling stage and foliar topdressing.
4. Prevention and control of pests and diseases
Powdery mildew and stripe rust are easy to occur in wheat heading and flowering period, so it is necessary to prevent and control them in time and use drugs in time to minimize losses. At the same time, spraying potassium dihydrogen phosphate and foliar fertilizer in combination with one spraying and three prevention can improve the disease resistance and yield of wheat.
