加拿大的一项研究表明,铜可控制小麦茎秆黑变病并增加产量.小麦品种Park在加拿大草原“Parkland”短生长季地区是最合适的栽培品种.然而它高度感染细菌性小麦茎秆黑变病.该病在田间的表现是出现深褐色的发病点片,其症状开始出现是在8月初,此时正值小麦生长的乳熟期.小麦茎秆黑变病发生在沙性土壤中,这种土壤含铜量较低.该病的发生降低了Al A study in Canada shows that copper can control blackening and increase yield of wheat stalks, and the wheat variety Park is the most suitable cultivar in the Canadian steppe “Parkland” short-growing season. However, it is highly susceptible to bacterial wheat stems Stalk black disease .This disease in the field performance is the emergence of dark brown spots, the symptoms began to appear in early August, at this time when the wheat growth milky maturity .Small stalk black disease occurs in the sand This soil has a low copper content in the soil, and the occurrence of this disease reduces Al
