我国大豆分布广,生态环境复杂,一般不施肥,加之复种指数高,缺乏合理轮作,黄淮、长江中下游产区易产生大豆缺素病。1982年以前,国外已对大豆氮、钾、钙、镁、锰、铁、锌等缺乏病进行过不少研究,解放以来,我国已编译研究了大豆部分营养元素缺乏病,但上述对大豆缺素症状的描述,彼此颇不一致,对大豆缺素罹病生理及黄淮、长江中下游大豆矿质营养概貌均未调查研究。因此,研究黄淮及长江中下游产区大豆缺素病症状诊断指标、缺素地域分布,为准确、迅速地对大豆缺素病科学诊治,具有应用与理论价值。
China’s soybean is widely distributed, the ecological environment is complex, generally not fertilizing, combined with multiple crop index high, the lack of reasonable rotation, Huanghuai, prone to soybean deficiency in the middle and lower reaches of the Yangtze River producing areas. Before 1982, a lot of studies have been done on the deficiency of nitrogen, potassium, calcium, magnesium, manganese, iron and zinc in foreign countries. Since the liberation, some nutrient deficiency in soybean has been compiled and studied in our country. However, Symptoms of the description, quite different from each other, the lack of physical and soybean deficiency disease Huanghuai, the middle and lower reaches of the Yangtze River mineral diet profiles were not investigated. Therefore, to study the diagnosis of soybean deficiency disease in the middle and lower reaches of the Yellow River and the middle and lower reaches of the Yangtze River Basin diagnostic indicators, geographical distribution of the lack of, in order to accurate and rapid scientific diagnosis and treatment of soybean deficiency, with the application and theoretical value.
