| 根据农田小气候观测资料,分析了冷型小麦陕229和对照品种9430的农田株间温、湿度 ,用 M.и布德柯法计算了株间的湍流热通量和潜热通量。结果表明 ,在灌浆期冷型小麦陕229比9430株间气温低0.1～1.9℃ ,湍流热通量低8.89～48.47J/(m2·s),株间水汽压和相对湿度分别高20～220Pa和1%～11% ,潜热通量高19.85～240.23J/(m2·s) ,即冷型小麦的株间环境具有冷湿的特征。这一特征有利于抗御小麦灌浆期干热天气的危害。 |

| Abstract: |
| Based on the observed data of farm land microclimate, this paper analyses temperature and humidity in the field of cold-type wheat Shaan 229 and 9430 (ordinary typewheat).The turbulentheat flux and latentheat flux in rows are calculated with М.и.ъудыко method. The results show that the air temperature of Shaan 229 in row is 0.1-1.9℃ lower than 9430 during milk-filling and the turbulent heat flux in row decreases 8.89-48.47J/(m2·s) compared with 9430.Thewater-vapour pressure, the relative humidity and the latent heat fiux of Shaan 229 are 20-220 Pa, 1% -11% and 19.85-240.23J/(m2·s) higher than 9430, respectively. In other words, the environmental characteristics of the cold type wheat are cooler and wetter in row.This characteristics are favorable to resist the dry-hot weather during milk-filling of wheat. |
