I. Introduction of Jiangmai 9 19
1. Variety source: Jiangmai 9 19, which was bred by Suqian Zhongjiang Seed Industry Co., Ltd. with Yin Zhong 179/ Wanmai 38/ Zhengmai 9023 in 2009.
2. Breeding unit: Suqian Zhongjiang Seed Industry Co., Ltd. ..
3. Approval number: Su Shenmai 20 1308.
Second, the characteristics
1, Jiangmai 9 19, a semi-winter medium-mature wheat variety, the whole growth period is 226.6 days, which is earlier than the control Huaimai 20 1 day. Strong tillering ability, good cold resistance in winter and general cold resistance in late spring. The seedlings are semi-creeping, with narrow and short leaves and dark green leaves. Compact plant type, plant height of 82.6 cm, and good stem elasticity. The ear layer is neat and looks handsome and mature. Spindle type, medium spike type, long awn, white shell and white grain, hard grain, good fullness and good appearance quality. The effective ear yield per mu is 390,000, with 32.7 grains per ear and 1000-grain weight of 42.3g. ..
2. Inoculation identification results: susceptible to scab, moderately susceptible to sheath blight, susceptible to powdery mildew and highly resistant to yellow mosaic virus disease.
3. Measured by the Center for Food Quality Supervision, Inspection and Testing of the Ministry of Agriculture, the average results in 2009-201two years were: bulk density 827.0g/L, crude protein content 13.6%, wet gluten content 30.7%, and stable time 6.3 minutes.
Third, the output performance
On 20/200911participated in the wheat regional test of Huaibei late sowing group in Jiangsu Province. The average yield per mu for two years was 500.6 kg, which was 6.0% higher than that of Zhengmai 9023 and 3.7% higher than that of Huaimai 20, and reached a very significant level on 20/200910. During 20 1 1-20 12 years, the average yield per mu was 47 1.7 kg, which was 4.4% higher than that of the control Huaimai 20.
Fourth, the applicable area.
Jiangmai 9 19 is suitable for late-maturing planting in Huaibei wheat area of Jiangsu Province.
Five, planting points
1, sowing date: the suitable sowing date is from the end of June 10 to the beginning of June 1 10.
2. Planting density:180,000-200,000 basic seedlings should be sown in time per mu. If the fertility level is low or sowing is delayed, the basic seedlings should be increased appropriately.
3. Fertilizer and water management: Generally, pure nitrogen 18kg, phosphorus pentoxide 8kg and potassium oxide 10kg are applied per mu. All phosphorus and potassium fertilizers are used as base fertilizer, with nitrogen fertilizer accounting for 60% of base seedling fertilizer and fertilizer accounting for 40% at jointing and booting stage. Spraying foliar fertilizer after heading and flowering combined with pest control. Winter irrigation is timely, and spring irrigation is appropriate. The field ditch system should be matched, and attention should be paid to flood control and drought prevention.
4. Prevention and control of diseases, pests and weeds: weeds in the field should be prevented in time before winter and early spring, and scab, sheath blight, powdery mildew and aphids should be prevented in the middle and late stage.
5. Harvest: harvest in time after maturity (at the end of wax ripening) to ensure high yield.
