江苏省宿迁市宿豫区小麦赤霉病自2003年大流行以来,2010、2012年又大发生,严重影响小麦产量和品质。通过对该区多年气象资料和小麦赤霉病田间调查资料的分析认为,小麦破口抽穗至扬花期间的温度高、空气湿度大是导致小麦赤霉病大流行的最关键的气候条件,小麦赤霉病的发病程度与小麦破口抽穗扬花期间20 d内的温度、空气湿度、降雨日数、日照时数有一定关系;小麦种植品种、防治时机、所用药剂品种剂量及用水量是导致小麦赤霉病流行的因素。小麦赤霉病综合防治应在农业防治的基础上,科学选准药剂、提早在小麦破口抽穗期预防。
Suji district, Suqian City, Jiangsu Province Since the pandemic of 2003, a large epidemic occurred in 2010 and 2012, seriously affecting the yield and quality of wheat. According to the field survey data of many years meteorological data and wheat scab in this area, it is considered that the temperature of the heading of wheat from heading to flowering is high and the humidity of the air is the most critical climatic condition leading to the wheat head blight. The incidence of mildew was related to the temperature, air humidity, rainfall days and sunshine duration within 20 days of wheat breaking and flowering. Wheat cultivars, control timing, dosages and water consumption of the cultivars used were the main cause of wheat germ The prevalence of the disease. Integrated control of wheat scab should be based on the prevention and treatment of agriculture, the scientific selection of pesticides, early breaking in the wheat heading stage prevention.
