小麦全生育期病虫草害综合防控试验示范研究

Integrated Control Experiment and Demonstration of Disease Pest and Weed for Wheat during Whole Growth Period

[目的]探讨适合陕西省三原县大面积推广的小麦全生育期病虫综合防治技术。[方法]在三原县开展了小麦全生育期病虫草害综合防控试验示范。[结果]组合药剂拌种处理能使小麦苗齐、苗壮,较对照农艺性状优良;进行全生育期综合防控的麦田,即实施组合药剂拌种、春季及时喷施除草剂进行麦田除草、抽穗-灌浆期的不同时期开展小麦病虫＂一喷三防＂,均有显著的病虫防效和增产率;以小麦抽穗率达60%~70%时实施第1次,隔7 d后实施第2次＂一喷三防＂的防虫、防病、增产效果更显著。[结论]试验结果为三原县小麦生产提供了参考。

[Objective] The aim was to explore integrated control technology of disease pest and weed for wheat during whole growth period in Sanyuan.[Method] Integrated control experiment and demonstration of disease pest and weed for wheat during whole growth period were carried out in Sanyuan County.[Result] Using combined agents to treat seed was helpful for the growth of seedlings,and agronomic traits of treatment was better than control.The integrated control experiment field got significant controlling effects against disease and pest and yield-increasing rate,that was seeds were treated by combined agents; herbicide was sprayed in spring; ＂one-spraying and three-controlling＂technology of disease and pests were carried out from heading to filling stage.The＂one-spraying and three-controlling＂technology was carried out firstly when the heading rate reached 60%-70%,and applied secondly in seven days,good disease and pests controlling effect and yield-increasing effect were got.[Conclusion] The results provide reference for the production of wheat in Sanyuan County.
