我所从1981年开始,调查了我省7个地区40个县、市,制成水稻线虫标本液600多份.初步鉴定与水稻有关的寄生线虫近20种.其中水稻根线虫数量最多,分布最广.每30克根中寄生有6～8千条,多的可达2～3万条.为了探讨水稻根线虫在我省条件下对农作物的影响,我们于1981年、1982年对水稻根线虫的致病性及其病原进行鉴定研究. Since 1981, we have investigated more than 600 rice nematode samples in 40 counties and cities in 7 regions of our province, initially identifying nearly 20 species of parasitic nematodes related to rice, of which the number of rice root nematodes is the most The most widely parasitic per 30 grams of root 6 to 8 thousand, up to 2 to 30 000. In order to explore the rice rootworm nematodes in our province under the conditions of the impact of crops, we in 1981 and 1982 on rice The pathogenicity of root nematodes and their pathogens were identified.
