Wheat powdery mildew dataset

Wheat powdery mildew. Wheat powdery mildew is a worldwide disease, which is distributed in all major wheat-producing countries. It occurs widely in the coastal areas of Shandong, Sichuan, Guizhou and Yunnan provinces and causes serious harm. In recent years, the disease has become more and more serious in wheat areas of Northeast, North China and Northwest China. The disease can damage the above-ground organs of wheat plants, but mainly leaves and leaf sheaths. Glume shell and awn can also be damaged when the disease is serious. [Control methods] Seed selection: Zhengzhou 8915, Zhengzhou 831, Yumai 9, 15, 16, 21, 24, Zhongyu 4, Beinong 9, Jimai 23, 24, 26, 84-5418, 138, Lumai 1, 5, 7, Chengfu 752, Gao 38, Guifeng 1, Guinong 19, 20, 21, 22, Qianfeng 3, 81-7241, Dongfeng 1, BT8812, BT-7032, Jinghe 883, etc. 8814, anther culture 28, Lumai 14, 22, Zhongmai 2, Jingnong 8445, etc. In addition, Bainong 64, Wenmai 4, Zhoumai 9, Xinbaofeng, Jishen 4185, 6021, Wanmai 25, 26, Yangmai 158, Chuanmai 25, Mianyang 26, Jinsong 49, Zaomai 5, Jinghua 1, 3, Jinghe3, Jing411, Beinongbai and so on were newly bred wheat varieties resistant to powdery mildew. Spring wheat varieties resistant to powdery mildew include Kenhong 13, Ken 95 and Dingfeng 3. The new disease-resistant varieties mentioned above can be selected according to local conditions. For example, Beijing winter wheat is now mainly cultivated in Beijing 411, and high-fertility wheat fields are combined with Jingdong 8, Jingdong 6 and Zhongmai 9. Drought-resistant and barren-resistant varieties such as Jing437, Jinghe No. 1 and Lunkang No. 6 were planted under medium fertilizer and poor irrigation conditions. Beijing 411, Jingdong 8 and Jingshuang 18 can be selected for rice stubble wheat and late sowing wheat fields. [Agricultural control] Enzyme-fermented compost or decomposed organic fertilizer should be advocated. Formula fertilization technology should be adopted, phosphorus and potassium fertilizer should be increased appropriately and planted reasonably according to variety characteristics and soil fertility. In order to prevent moisture retention, wheat areas in southern China should drain water in time after rain. Water the wheat in the north of China in time to enhance the disease resistance of the host. In the areas where autumn wheat seedlings oversummer, it is necessary to remove autumn wheat before autumn sowing, which can greatly reduce the source of autumn wheat seedlings.
