摘要
对不同立地条件下分关1号黄栀子从幼树到盛果期树高、冠幅和结果量等进行调查研究,结果表明:造林地的立地条件直接影响分关1号黄栀子的树冠生长量和结果量:9年生时,Ⅱ-类地的平均树高1.44 m,是Ⅳ类地的1.37倍,是Ⅲ类地的1.15倍;平均冠幅1.82 m,是Ⅳ类地的1.19倍,是Ⅲ类地的1.11倍;7年平均总结果 18.509 kg.株-1,是Ⅳ类地的1.73倍,是Ⅲ类地的1.4倍。建议Ⅲ、Ⅳ类地可通过提高种植密度,以充分利用空间地力提高经济效益,同时尽早郁闭改善林分的立地状况。
Through the investigation and research on the height,canopy and individual yields of No.1 FenGuan yellow gardenia from sprouting to full productive age on different growing conditions,the study indicated as follows: the growing condition of planting locations made an immediate impact on the crown growing and yields of No.1 FenGuan Yellow Gardenia.Planted at sunny Ⅱ-sites,the average height of a 9-year-old tree would achieve 1.44 meters,which was 1.37 times of the height of that at Ⅳ sites and 1.55 times of the height of that at Ⅲ sites;the average crown reached 1.82 meters,which was 1.19 times of the width of that at Ⅳ sites and 1.11 times of the with of that at Ⅲ sites;the average yield of an individual 7-year-old tree achieved 18.509kg,which was 1.73 times as many as that at Ⅳ sites and 1.4 times as many as that at Ⅲ sites.The study advocated that Ⅲ and Ⅳ sites should increase planting densities in unit area to fully utilize space for improving economic profits.Meanwhile,closing the crown as early as possible could improve the growing conditions.
