| 摘 要： | 对比试验结果表明,杂交晚稻秧田不施或少施基肥和苗肥,培育青色、青黄色健壮秧苗,适当增加大田插本数,可以显著减少水稻黑条矮缩病发病率,增加产量。在对照区平均丛发病率12.8%,平均单产435.5kg/亩情况下,秧田不施肥,大田每丛插2本苗的丛发病率可控制在1%左右,亩产增加100kg上下。

| Abstract: | The results of comparison experiments showed that the incidence of rice black streaked dwarf Fijvirus (RBSD) can be decreased and rice yield can be increased by raising seedlings in seedling bed without or with less base and seedling fertilizer, raising strong seedlings and increasing the seedling amount in paddy fields. The mean diseased hill percentage in the control area was about 12.8%, and the rice yield was 435.5 kg/mu. When there were two ben seedlings per hill and no fertilizer was applied in seedling bed, the diseased hill percentage was about 10%, the yield also had an increase of 100 kg. |
