- 摘要:
- 为探索适合黑龙江地区的水田灌溉方式,以空育131为试材,通过田间小区试验,研究了不同灌溉方式与寒地水稻主要病害发生和产量形成的关系。结果表明:病害发生种类与灌溉方式无显著相关性,但与病害发生程度有紧密联系。常规灌溉的水稻叶瘟、鞘腐病、褐变穗发病率和病情指数均最高。控水灌溉和节水灌溉病害发生较轻。产量方面,控水灌溉的产量最高,为10 049.03 kg·hm-2,比常规灌溉增产6.81%,增产效果明显。
- Abstract:
- In order to explore the suitable irrigation method for Heilongjiang province,taking rice variety Kongyu 131 as test material,field experiment was conducted to study the relationship of rice disease occurrence and yield-building with different irrigation methods.The results showed that there was no significant correlation between disease type and irrigation methods,but disease type was closely connected with occurrence severity.Under conventional irrigation,the morbidity rate and the disease index of rice blast,acrocylindrium oryzae,rice browning ear were higher than water control irrigation and water saving irrigation.The yield of water control irrigation was the most,it’s 10 049.03 kg·hm-2,which is increased 6.81% than that of conventional irrigation.
