本文综合报道笔者自1982年以来研究四川稻区水稻褐鞘症的进展情况。主要结果如下: （1）褐鞘症在四川普遍发生,主要在水稻生长后期（孕穗期以后）,可造成稻谷产量损失5—10%。 （2）该症状系由稻叶褐鞘腐败病菌（Sarocladium oryzae）的侵染引起,在稻株上活动的鼹鼠跗线螨（Tarsonemus talpae Schaarschmidt）能够携带和传播该病菌,从而起着加重褐鞘症表现的作用。 （3）环境因子中,品种和施肥水平是影响褐鞘症的重要因素。不同品种上症状的严重程度呈现差异,当前的当家品种均受害严重,尤以杂交水稻最甚。施氮水平愈高者,症状发生愈严重。 （4）褐鞘症的药剂防治以杀菌剂与杀螨剂配合施用效果较好。
This article comprehensively reports the progress of Oryza sativa from rice in Sichuan since 1982. The main results are as follows: (1) Brown sheath disease occurs in Sichuan, mainly in the late rice growth stage (after booting stage), which can cause the loss of rice yield by 5-10%. (2) This symptom is caused by the infection of Sarocladium oryzae, and the Tarsonemus talpae Schaarschmidt, which is active on rice plants, is capable of carrying and transmitting this bacterium, thereby playing a heavy brown Sphincter manifestation of the role. (3) Among the environmental factors, the variety and fertilization level are the important factors that affect brownhead syndrome. The severity of the symptoms on different varieties show differences, the current leader of the species are seriously harmed, especially hybrid rice is the worst. The higher the nitrogen level, the more serious the occurrence of symptoms. (4) prevention and treatment of brown sheath disease with fungicides and acaricides with better effect.
