栽培小麦的丰产技术包括有增施无机肥料,但肥料会影影到植物的感病性,改变有害和有益微生物的相互关系。1976~1982年我们在伏尔加格勒地区灌溉土地上进行了不同施肥量对叶锈病、杆锈病、白粉病和交链孢菌引起的穗部黑霉病抗病性影响的试验。在前面三个处理中(不施肥、P_(90)K_(90)、N_(60)P_(90))当氮肥的施用量从0~60公斤/公顷时,冬小麦品种白粉病和叶锈病的发病率均较低
High-yielding techniques for cultivated wheat include enhanced inorganic fertilizers, but fertilizers can affect the plant’s susceptibility and alter the interrelationship between harmful and beneficial microorganisms. From 1976 to 1982, we conducted experiments on the effects of leaf rust, rod rust, powdery mildew and Alternaria on the disease resistance of panicles caused by Alternaria sp. On irrigated land in the Volgograd region. In the first three treatments (no fertilizer, P_ (90) K_ (90), N_ (60) P_ (90)), the nitrogen fertilizer application ranged from 0 to 60 kg / ha. The incidence is low
