郭予元院士在宁夏植保防控事业中的学术贡献——纪念郭予元院士诞辰90周年

Contribution of Academician Guo Yuyuan to plant protection in Ningxia——To commemorate the 90th anniversary of the birth of Academician Guo Yuyuan

五六十年代的宁夏,农业发展落后,农业科学发展刚刚起步,引黄灌区的水稻和南部西海固地区的冬小麦分别是当地的主要粮食作物,其产量直接关乎当地群众温饱。但是由于特殊的地理位置和气候特点,这些地区病虫害发生严重,制约了当地的粮食生产。本文回顾了郭予元院士在宁夏进行病虫害科学研究,为水稻稻瘟病、小麦麦种蝇和小麦腥黑穗病的监测预警,防治示范做出的突出贡献。郭予元院士建立的预测预报体系及防治技术示范一直指导当地的农业生产,并给全国的病虫害防治做了示范。

In the 1950s and 1960s,agricultural development was backward,and development of agricultural science just started in Ningxia.Rice in the irrigation area of Yellow River diversion and winter wheat in the southern Xihaigu area are important crops,which are directly related to the food of the people.However,due to the special geographical location and climatic characteristics of these areas,the agricultural pests and diseases were very serious,which seriously affected the local food production.This paper reviews Academician Guo Yuyuan’s outstanding contribution to the monitoring,early warning and controlling of rice blast,Delia coarctata and common bunt of wheat.The prediction and forecasting system and technology demonstration established by Academician Guo Yuyuan have been guiding local agricultural production and serving as a demonstration for disease and pest control across the country.
