| 摘 要： | 田间试验表明水稻潜根线虫病（Ｈｉｒｓｃｈｍａｎｎｉｅｌｌａｓｐｐ．）的药剂防治最适时期在水稻返青期，该时期施用杀线虫剂呋喃丹３％颗粒剂防治稻根线虫可使水稻增产２３．６％．其次为始蘖期，水稻增产率为１８．８％；移栽期施药的水稻增产率为１２．３％．增产作用表现为提高水稻的有效穗数和千粒重．

| Abstract: | The turn green stage of transplanted rice seedling was the optimum time of chemical control for rice root nematode (Hirschmanniella spp.). Using carbofuran in the turn green stage to control Hirschmanniella spp. has increased 23.6% of yield. Tins chemical control has increased 18.8% of rice yield in the beginning tillering stage and 12.3% in the transplanting stage. The effects of increase production were expressed by improvements of the effective tillering and the grain weight. |
