Rainy days to prevent and control wheat powdery mildew
Rainy days are beneficial to the occurrence of wheat powdery mildew. Agrotechnologies 001 studio experts found that wheat powdery mildew aggravated during the field survey and reminded local authorities to take care of the disease. The reporter learned from the Provincial Planting and Protecting Station of the Agriculture and Forestry Department that the occurrence of wheat powdery mildew in the northern part of Huaibei and the northern part of the coast of our province has become more serious this year. Although the disease rate in the field is high, the incidence is not heavy, and the overall incidence is lighter than last year. Judging from the weather conditions, the drought and rain in the early period in the Huaibei region were not conducive to disease. In the near future, more rain and more favorable to diseases occurred. The rainfall in Huaibei area in spring is less than that in Huainan area, and the incidence is generally light. However, due to the low amount of field bacteria in the Huainan area in the past two years, the incidence is lighter. The wheat varieties used in production have different disease resistance. Among wheat varieties in the south of the Huaihe River, Yangmai 11 and Yangmai 12 are more susceptible to powdery mildew, Ningmai 8, Ningmai 9, and Ningmai 13 and other wheat varieties. In Huaibei wheat region, there are many varieties of wheat imported from other regions. The varieties of Yannong 19, Shaan 229, and Wanmai 19, which are planted in large areas, are generally susceptible or susceptible to powdery mildew. For wheat varieties that are susceptible to powdery mildew, special attention should be given to observe the occurrence of powdery mildew in the field and to control it with appropriate drugs. Triadimefon is currently one of the best agents for the control of wheat powdery mildew. At the beginning of May, the province had already used one drug in combination with scab disease prevention throughout the province. Now, for heavy-weight fields, we can use 15% triadimefon 60g or 12.5% ​​konjac WP 20-30g per acre, plus 50kg of water spray.

Altitude: high altitude area light, clean air, environment close to original condition, no industrial pollution. With an average elevation of 1160-2900m, the central health center has a strong uv light, which produces the natural pollution-free apple, which conforms to the concept of a modern green diet.
Temperature: moderate temperature can avoid the chance of fruit tree encountering disease. The average temperature in ningxia is 8.4 degrees Celsius, which has an important influence on the growth, development, yield and quality of apple. The piedmont apple is thriving in such a good environment.
Humidity environment: moderate amount of rainfall provides necessary conditions for apple's growth. The annual rainfall in the central health region is 186 millimeters. The fruit is slow to grow and the fruit is hard and hard, which fully guarantees the fruit's sugar content and the relatively average size of apples.
Sunshine condition: apple is the fruit tree, the central health area of the whole year is nearly 3,800 hours, is beneficial to the Apple Fruit coloring. The piedmont apples are red and bright.
Temperature difference factors: ambassador apple nighttime respiration weak temperature gap between day and night, consume less organic matter, the accumulation of organic matter during the day more, that apple store down a large number of glucose sugar candy, etc have better taste. The average diurnal temperature difference between apple and apple is 14 degrees centigrade, and the larger diurnal temperature difference ensures the sweet and delicious characteristics of the apple.
Other factors: frost can make apple blossom and fruit, which can cause frozen flower jelly, which is bad for apple's production. The piedmont apple has been kept at least 167 days without frost for the whole year, which minimizes the influence of apple on yield and quality.
