| 摘 要： | 试验结果表明 ,玉米粗缩病的发生为害有一定规律性 ,并且与播期和品种关系密切。用化学药剂防治和增施磷肥对此病有一定的预防效果。 1996～ 1997年试验 6个播期 ,发现在 5月 5,15日播种的发病重。 1998～ 2 0 0 0年试验 4个品种 ,发现不同品种对粗缩病的抗性差异很明显。喷药和施肥防病措施对抗病和耐病品种作用不大 ,而对感病品种有明显防病效果

Studies on Comprehensive Prevention Techniques of Maize Rough Dwarf |
| |
| Abstract: | Experiments indicated the occurrence of maize rough dwarf had a regular pattern, and it was closely related with sowing dates and corn cultivars. The chemical medicines and phosphate fertilizer application had definite prevention effects on maize rough dwarf. The disease occurred seriously when sowing on May 5 and May 15 among six sowing dates in 1996 and 1997. The disease-resistance had significant different in four corn cultivars in 1998～2000. Medicine spraying and fertilizer application had not obvious effects on the disease for resistant and disease tolerance corn cultivars, but significant effects for the non-resistant disease corn cultivars. |
