摘要
气候因素是影响农业生产最为重要的因素之一,它提供的光热、水分、风向等自然因素对农业生产方式、种植模式、生产潜力以及质量和经济系数都起着决定性作用,气候条件的发生改变还导致了作物的病虫害的发生进而影响作物的生长发育。培育抗逆性强的谷子新品种是解决这一问题的重要途径之一。鉴定不同谷子品种的抗逆性,可以为培育高产优质的谷子新品种奠定基础。本试验主要在冀东地区气象条件下研究了不同谷子品种的抗逆性。在相同的气象和栽培管理条件下,以豫谷18为对照,对16个谷子品种进行了抗逆性与产量的比较研究,通过试验表明:郑谷607、冀谷41、冀谷T8、沧15-298、济谷20、济谷21、豫谷31、衡谷17对红叶病的抗性强于对照品种表现为免疫;中谷6、衡谷16和衡谷17对白发病的抗性与对照品种相同表现为免疫;保谷23、郑谷607、冀谷40、冀谷41、冀谷T8、沧谷9号、济谷20、济谷21、泰谷002、衡谷16对纹枯病的抗性弱于对照品种;参试品种对谷瘟病均表现出抗性;郑谷607、冀谷40、冀谷41、冀谷T8、沧15-298、中谷6、济谷20、济谷21、豫谷31、衡谷16的产量高于对照品种,在相同的气象和栽培管理条件下不同的谷子品种对不同的病虫害表现出不同的抗性和生产力。
Climatic factors play a decisive role in agricultural production methods,planting patterns,production potential,quality and economic coefficients.Changes in climatic conditions can also lead to the occurrence of crop diseases and insect pests and affect crop growth and development.Cultivating new millet varieties with strong stress resistance is one of the important ways to solve this problem.This experiment mainly studied the stress resistance of different millet varieties under the meteorological conditions in eastern Hebei.Under the same weather and cultivation management conditions,with Yugu 18 as a control,16 millet varieties were compared for stress resistance and yield.The test showed that Zhenggu 607,Jigu 41,Jigu T8,Cang 15-298,Jigu 20,Jigu 21,Yugu 31,and Henggu 17 were more resistant to red leaf disease than the control variety,which showed immunity;Zhonggu 6 The resistance of Henggu 16 and Henggu 17 to white disease is the same as the control variety;Baogu 23,Zhenggu 607,Jigu 40,Jigu 41,Jigu T8,Canggu 9,Jigu 20,Jigu The resistance of Gu 21,Taigu 002,and Henggu 16 to sheath blight is weaker than that of the control varieties;the tested varieties all show resistance to grain blast;Zhenggu607,Jigu 40,Jigu 41,Jigu T8,The yields of Cang 15-298,Zhonggu 6,Jigu 20,Jigu 21,Yugu 31,and Henggu 16 were higher than the control varieties.
