| 本文用自然状态下干热风处理的方法,经过两年田间试验,初步认为:高中秆小麦品种忍耐千热风害的能力比现有的矮杆品种强;抗寒性偏弱的品种抵抗干热风的能力比抗寒性强的小麦品种强;早熟或早中熟品种在华北地区能够避开干热风的危害。这些论点,对千热风多发地区小麦品种的合理布局和培育抗干热风品种时杂交组合的选择有着一定的参考意义。 |

| Abstract: |
| The results of the experiment by means of the hot-dry wind treatment under natural conditions in the field for 2 years may be summarized as follows: The high-medial stalk types of wheat are more resistant to hot-dry wind than the short ones;the less hardy wheat varieties are more resistant to the hot-dry wind than the hardy ones;the early or early-medium wheat varieties can avoid the hot-dry wind burn in several regions of North China. These conclusions may be of value for distributing the wheat varieties a... |
