山旱地小麦条锈病综合防治技术研究

目的]为了调查山旱地小麦条锈病综合防治技术的应用效果,以便有效防控小麦条锈病。方法]于2004年小麦收获前对安康市小麦主产区的8县(区)、23个乡镇、32个村、182户、12.45hm2麦田,2005年对7县区、16个乡镇、20个村的106户、10.43hm2麦田,2006年对8县区、19个乡镇、24个村的118户、9.93hm2麦田进行了小麦品种、播期、间套、施肥、种子处理方法、药剂喷雾和经济性状等因素的大田调查及产量测定。结果]三唑酮拌种较对照增产23.91%,种子包衣较对照增产28.04%,三唑酮拌种与种子包衣产量差异不大。叶面喷雾1次产量增加24.75%,喷雾两次增加36.19%,喷雾2次的效果优于1次。结论]在条锈病大发生年份,药剂拌种加叶面喷雾防治效果更佳。

Study on Integrated Control Technology of Wheat Stripe Rust in Mountainous Areas

Objective] The study aimed to investigate the application effect of integrated control technology on wheat stripe rust in mountainous areas so as to control the wheat stripe rust effectively. Method] The field investigation on factors such as wheat varieties, sowing stage, interplanting, fertilization, seed treatment, medicament spraying and economic traits and the yield determination were conducted in total 12.45 hm2 wheat field of 182 households from 32 villages of 23 towns in 8 counties in 2004; in total 10.43 hm2 wheat field of 106 households from 20 villages of 16 towns in 7 counties in 2005 and in total 9.93 hm2 wheat field of 118 household from 24 villages of 19 towns in 8 counties in 2006 in main wheat production areas of Ankang City before wheat harvest. Result] Compared with CK, the seeds dressed with triazolone increased the yield by 23.91 %, the seeds covered increased by 28.04 % and their yield difference was little. Spraying on leaves for once increased the yield by 24.75 %, twice increased by 36.19 % and the effect of spraying for twice was better than that of spraying for once. Conclusion] In the years when the strip-rust disease happened greatly, the seeds dressing with medicament combined with spraying on leaves would get better control effect.
