在尼日利亚伊巴丹大学,1974年曾进行一个木薯肥料试验。与试品种为易感细菌性萎蔫病的53101和抗此病的60506。除施适当的氮、磷肥外,有每公顷施氧化钾0、60、90和120公斤四个处理。结果表明,53101和60506植株的细菌性萎蔫病发病率,每公顷施氧化钾60公斤的分别为70.5％及44.4％,而未施钾肥的对照区分别为74.4％及56.2％。每公顷施氧化钾90公斤的发病率显著降低。
At Ibadan University in Nigeria, a cassava fertilizer test was conducted in 1974. And the test species susceptible to bacterial wilt disease 53101 and the anti-disease 60506. In addition to the proper nitrogen and phosphorus fertilizers, there are four treatments of 0, 60, 90 and 120 kg of potassium per hectare. The results showed that the incidence of bacterial wilt disease in plants of 53101 and 60506 was 70.5% and 44.4% for 60 kg of potassium per hectare, respectively, compared with 74.4% and 56.2% in the control plants without potassium fertilizer. The incidence of 90 kilograms per hectare of potassium oxide was significantly reduced.
