水稻云形病的研究

介绍了水稻云形病的病原特征、侵染循环、发生规律和危害症状，提出防治该病应选用无病种子和抗病良种；收割后及早将病稻草清理，搬离田间堆放，作牛栏的垫草应堆沤腐热后才能当肥料使用；采用配方施肥技术，合理施肥，防止偏施氮肥，增施磷钾肥；浅水灌溉；栽培密度不宜过大。另外在加强栽培管理，提高植株抗性的基础上，采取生长期喷药保护为重点的综合防治措施。为减轻水稻云形病的危害，提高水稻的产量和品质提供了一定的依据j

Research on Rice Clouds Form Disease

Causes and signs of rice clouds form disease were introduced as well as its infection cycle, occurrenee laws and damage symptoms.Control measures include selecting healthy and disease-resistant seeds; removing diseased straws timely after harvest, using the straws as fertilizer only after full fermentation; using formulated fertilization technique, applying nitrogenous, phosphorus and potassic fertilizer reasonably; shallow water irrigation; keeping moderate density. Moreover, the comprchensive prevention measures were proposed on the basis of strengthening cuhivation managements to improve disease-resistant ahility of rice, anti adopting fungicide control in the growth phase as key measures. The study provided a support for relieving damages of rice clouds form disease, improving yiehl anti quality of rice.
