气象条件对甘肃冬小麦条锈病流行的影响研究

Impact of Meteorological Condition on Stripe Rust of Winter Wheat in Gansu Province

应用积分回归的方法分析了甘肃省东部地区气候条件对条锈病发生、发展的影响。结果表明:气温的影响在中部和北部以负效应为主,南部以正效应为主;降水、相对湿度的正效应十分明显,且影响效应大于温度。总体而言,甘肃东部的气候环境有利于小麦病虫害的发生发展。

The stripe rust is one of the most principal disaster for crops in East of Gansu Province, where is the main region of planting winter wheat. The impacts of the local climatic conditions on the eruption and expansion of the rust are analyzed by using the integral regression method. The results show that the impact of temperature is negative in middle and north region, while positive in south region. The impacts of precipitation and relative humidity are obviously, and their effects are more than temperature. Generally, the climatic conditions are in favor of eruption and development of the stripe rust in East of Gansu Province.
