The relationship between the fruit quality and the relative light intensity,and the number of branches and leaves in trellis-trained‘Hwangkumbae’(Pyrus pyrifolia ‘Hwangkumbae’) was studied.
为了探明棚架栽培黄金梨果实品质与相对光照强度和枝(梢)叶的关系,应用树冠分格方法系统研究了冠层不同部位相对光照强度的变化、枝(梢)叶空间分布特征和果实品质差异及相对光照强度与果实品质和枝(梢)叶关系。
The results were as follows: as for wine made by grape from pergola system, it had a few kinols of higher alcohols and lower cont.
结果表明,棚架栽培与篱架栽培相比,其葡萄酒中杂醇的种类较少,其含量除辛醇、苯甲醇和苯乙醇外均较低;酯类化合物种类较多,乳酸乙酯、乙酸乙酯、丁二酸二乙酯含量较低,己酸乙酯、辛酸乙酯、乙酸苯乙酯和乙酸-3-甲基丁酯含量较高;除里哪醇的含量明显较低外,其他萜类化合物的含量均较高。
Based on the concept of piperoof-support system,a 3D analysis model was developed for the insight to the function of piperoof applied in underground engineering of soft ground.
针对软弱地层管棚法施工过程,从棚架体系视角,建立了可用来分析管棚作用的空间分析模型。
The canopy structure characteristics, yield, and quality differences were comparatively investigated between the horizontal trellis system (HTS)and the delayed-open central leader system (DLS) of‘Hosui’ pear tree with WinSCANOPY2005a for hemispherical image analysis.
以‘丰水’梨棚架形与疏散分层形两种树形为对象,应用WinSCANOPY2005a冠层分析仪比较研究了两种树形的冠层结构特点、产量、品质差异及其相关性,结果表明:棚架形平均叶倾角,冠层开度,冠下直射、散射及总光合光量子通量密度显著或极显著高于疏散分层形,而叶面积系数极显著低于疏散分层形。
