1974—1976年,我们在广东的海南、湛江以及广西的钦州等地调查水稻根结线虫病的过程中,曾多次发现另一类线虫寄生水稻根部的现象,经鉴定证明是由于潜根线虫(Hirsc-hmanniella spp.)侵染水稻,引起水稻潜根线虫病。水稻潜根线虫病广泛分布在世界各水稻产区。美国、日本、印度、缅甸、印度尼西亚、泰国、菲律宾、斯里兰卡、孟加拉、马来亚、马尔加什、尼日利亚、塞拉利昂、委内瑞拉以及我国的台湾省都有此线虫病发生的记载。 1978年以来,我们对此线虫病害进行了初步的调查和研究,现简报如下。
During 1974-1976, when we surveyed root-knot nematode disease in Hainan, Zhanjiang, Guangdong and Qinzhou of Guangdong, we found many times that the root of another kind of parasitic nematode rice had been found. It was proved that the root-knot nematode (Hirsc-hmanniella spp.) Infected rice, causing rice rootstock nematode disease. Rice rootstock nematode disease is widely distributed in the world’s rice producing areas. The incidence of nematodes in the United States, Japan, India, Myanmar, Indonesia, Thailand, the Philippines, Sri Lanka, Bangladesh, Malaya, Malagasy, Nigeria, Sierra Leone, Venezuela and our country’s Taiwan Province is documented. Since 1978, we conducted a preliminary investigation and research on this nematode disease and are briefed as follows.
