摘要
为了改进杏树的栽培技术,提高果实品质,应用树冠分格方法研究了2种不同主枝开张角度自然开心形杏树冠层内光照强度、温度和相对湿度的差异。结果表明:2种冠形树冠内相对光照强度从下到上、从内到外逐渐增强,且60°自然开心形树冠内有效光区比30°自然开心形大2.66%;60°自然开心形树冠内不同部位光照强度、温度略高于30°自然开心形,最大温差达到3.8℃;而30°自然开心形树冠内相对湿度大于60°自然开心形,最大差值达到10.7个百分点;温度的分布规律和光合有效辐射基本一致,相对湿度的分布与光合有效辐射和温度的分布大体相反。
In order to improve culture techniques of canopy and to enhance fruit quality, differences of light intensity, temperature and relative humidity in canopy of apricot trees with two views of main branches was researched, by using crown cell method. The results showed that distribution of relative light intensity in canopy of two crown shapes is gradually increased from lower to upper, from inner to outer, and the effect light region of 60° crown shape is more 2.66% than that of 30° crown shape. The light intensity and temperature in the canopy of 60° open centre shape are higher than those of 30° open centre shape, and the biggest temperature difference is 3.8 ℃ . But the relative humidity in the canopy of 30° open centre shape is higher than that of 60° open centre shape, and the biggest difference is 10.7 percentage point. The distribution of temperature and light intensity is basic consistent, but the distribution of relative humidity is gross opposite with that of temperature and light intensity.
