| 摘 要： | 通过对3个县8个山坡地的考察,探索山地丘陵坡地逆温效应对果树避冻的影响。试验对三年来冬季观测到日最低温度（td）进行拟合处理,运用趋势线分析探究温差（△td）与相对坡位（G）之间的总体趋势,采用相关回归方差分析方法对△td与G进行差异显著性检验。结果表明：△td与G相关达到极其显著水平。对于高差（△H）〈50m的山坡,晴夜最低气温随高度的增加而增加,越近坡顶,最低气温越高;对于76m≤△H〈150m的山坡,在该山坡相对坡位0．63以上,晴夜最低气温常出现最高,逆温效应明显。总高差不足150m山坡最大逆温效应出现的坡位G与山坡总高差成反比,即随着△H的增加,最大逆温效应出现的坡位G值逐渐变小。利用这些结果进行果树科学合理建园,发展山区特色果业,对不耐寒果树安全避冻意义重大。

| Abstract: | The test explored the effect of sloping field temperature inversion on fruits' avoiding freezing injury in mountainous region where investigated eight hillsides through three counties.The test applied trending line analysis to explore general trend and adopted regression and correlation ANOV analysis methods to test the significance of difference between relatively sloping location and temperature difference where observed low temperature(td) was fitting treatment through three years in winter.The results i... |
