为探究锥栗树体合理的修剪强度,以7年生'华栗3号'锥栗为试材,通过轻修剪(15%修剪量)、中修剪(30%修剪量)、重修剪(45%修剪量)和不修剪(对照)处理,研究了不同修剪强度对锥栗叶片质量、矿质元素含量和光合作用以及产量的影响。结果表明,不同修剪强度对锥栗不同冠层叶片质量影响不同,其中中修剪综合效果最好,在冠层上部,其单叶面积最大为72.92 cm~2,比对照增加了18.38%;在树冠中部和下部,叶片厚度均显著大于轻修剪和对照处理;中修剪的冠层下部叶片SPAD值分别较重修剪、轻修剪和对照增加4.27%、8.05%和8.29%。中修剪处理显著提高了叶片中N、P、K和Ca含量,但中修剪与重修剪Ca含量差异不显著,重修剪叶...

In order to explore the reasonable pruning intensity of Castanea henryi, we used 7 years C. henryi 'Huali No.3' as experimental materials to study the effects of different pruning intensities on leaf quality, mineral element contents, photosynthesis and yield by light pruning (15% pruning), medium pruning (30% pruning), heavy pruning (45% pruning) and non-pruning (control) treatments. The results showed that different pruning intensity had different effects on the leaf quality of C. henryi canaliculata, and the mid-pruning had the best effect. ...
