影响小麦条锈病流行的气象因子依次为雨量、日照时数、温度。特别是3月中、下旬到4月上旬的降雨量对条锈病的发生流行至关重要。据此建立了中长期预测预报模式。小麦锈病的发生期大多在1~2月,最早的在12月中、下旬。2~3月份为病害高峰期,4月份为严重危害期,播种期越早发病也越早。病害流行扩展快。目前我省条锈病菌的优势小种为条中30、31号,新小种水源类型正在迅速上升,已达20%。较抗条锈病的品种有川农麦1号、SW89-3243、川麦26等。该文还进行了品种混植防病技术和种衣剂研究。筛选出对小麦锈病有特效、保护效果突出的新药剂敌利脱。小麦条锈病的防治最适期是始穗期。
The meteorological factors affecting the prevalence of stripe rust in wheat were rainfall, sunshine duration and temperature. In particular, rainfall in late March and early April is crucial for the occurrence of stripe rust. Based on this, a medium- and long-term forecasting model has been established. Most of the occurrence of wheat rust in January to February, the earliest in mid-December, late. 2 ~ March is the peak of disease, April is a serious damage period, the sooner the sowing disease onset. Epidemic spread rapidly. At present, the dominant species of stripe rust in our province is Article No. 30 and No. 31, and the types of water sources of the new races are rapidly increasing, reaching 20%. Stripe rust resistant varieties Chuannongmai 1, SW89-3243, Chuanmai 26 and so on. The article also carried out a variety of mixed disease prevention technology and seed coating research. Screening out the special effects of wheat rust, the protection of the new drug elixir off prominent. Wheat stripe rust prevention and treatment of the most suitable period is the beginning of the panicle.
