甘蔗凤梨病是甘蔗种苗的毁灭性大病害。以往在单一春植制度下,凤梨病是在早春种植的情况下发生较严重。随着甘蔗栽培制度的改革,凤梨病在冬植蔗和秋植蔗中也同样发生为害。特别在大力发展秋植甘蔗中,我省海南岛北部、湛江雷州半岛以及珠江三角洲推广稻底蔗的地方,都曾先后出现部分地方受凤梨病为害以致种苗绝大部分不发芽而造成栽植失败的事例。我们曾先后在海南和湛江两个旱地蔗区对甘蔗凤梨病的发生、为害以及防治方法等作过一些试验。现提出有关凤梨病发生与防治的 Sugarcane pineapple disease is a devastating disease of sugarcane seedlings. In the past in a single spring planting system, pineapple disease is more serious in the case of planting in early spring. With the reform of sugar cane cultivation system, pineapple disease also occurs in winter and autumn cane. Especially in the development of autumn planting sugarcane, the province of northern Hainan Island, Zhanjiang Leizhou Peninsula and the Pearl River Delta to promote rice cane areas, have occurred in some places by the pineapple disease caused by the vast majority of seedlings do not cause sprouting and planting failed The case. We have done some experiments on the occurrence, damage and prevention and cure of sugarcane pineapple disease in two dry land cane areas in Hainan and Zhanjiang successively. Now put forward the pineapple disease occurrence and prevention
