调查了不同甘蔗品种、施肥水平、蔗田地势及气候条件下,甘蔗黄点病的发生情况。结果表明,甘蔗品种间对黄点病的抗(感)病性存在显著差异,Roc部分品种较感病,其中Rco10最感病;79/177、71/210、93/293及果蔗等品种(系)较抗病.氮肥可加重黄点病发生,钾肥可减轻黄点病发生。蔗田地势低洼、易积水,病害发生严重.温度适宜、天气长期阴雨、田间湿度大,有利于黄点病发生;在此条件下,若遇台风袭击,黄点病可能大流行.
The occurrence of yellow dot disease in sugarcane under different sugar cane varieties, fertilization levels, topography of cane fields and climatic conditions were investigated. The results showed that there were significant differences in anti-flu susceptibility of yellow croaker among sugarcane cultivars, and some of Roc were susceptible, of which Rco10 was the most susceptible; 79 / 177,71 / 210,93 / 293 and sugarcane (Department) is more resistant to disease. Nitrogen can aggravate yellow dot disease, potassium can reduce yellow dot disease. Cane fields low-lying, easy to accumulate water, serious disease. Suitable temperature, long-term overcast and rainy weather, field humidity, is conducive to the occurrence of yellow point disease; in this condition, the case of typhoon attack, yellow dot disease may pandemic.
