根据农田小气候观测资料 ,分析了冷型小麦陕 2 2 9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 2 2 9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 2 0～ 2 2 0 Pa和 1 %～ 1 1 % ,潜热通量高 1 9.85～ 2 4 0 .2 3J/(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。
Based on the observation data of cropland microclimate, the temperature and humidity of the farmland of cold-type wheat-Shaannei 229 and the control 9430 were analyzed. The turbulent and latent heat fluxes between the strains were calculated by the M. и Budeko method. The results showed that during the filling stage, the air temperature of cold-headed wheat with the ratio of 2 29 to 9430 was lower by 0.01-1.9 ℃ and the turbulent heat flux was 8.89-48.47J / (m2 · s) The humidities were 20 ~ 20 Pa and 1% ~ 1 1%, respectively, and the latent heat flux was 1 9.85 ~ 24.023J / (m2 · s) feature. This feature is conducive to the resistance to dry wheat during grain filling dry heat hazards.
