摘要
研究了不同立地条件、不同经营措施对高氏甜龙竹生长的影响。结果表明:在云南、四川、重庆等10个不同环境条件的试验点,高氏甜龙竹的生长状况差异显著,其中在云南省元江县、重庆市武隆区和云南普洱市思茅区生长较好,3年生竹笋年产量分别达到30.03、27.23和26.20 t/hm^(2),而在云南嵩明县的生长相对较差,笋年产量仅为10.93 t/hm^(2);经营措施也影响着高氏甜龙竹的生长,采用全面整地,旱季时每月对竹丛进行1次浇水,浇水量为900 kg/丛,造林时施用大量有机肥,出笋高峰期施适量的氮、磷、钾复合肥(500 g/丛),可促进竹林生长,提高笋产量和笋品质。
The effects of different site conditions and forest management measures on the growth of Dendrocalamus brandisii cv.songmingensis are studied.The results show that there are significant differences in the growth of D.brandisii cv.songmingensis in 10 experimental sites in Yunnan,Sichuan and Chongqing.The bamboo forests grow better in Yuanjiang county of Yunnan province,Wulong district of Chongqing city and Simao district of Pu er city of Yunnan,with the annual shoot yield of 3-year-old bamboo forest at 30.03,27.23 and 26.20 t/ha,respectively,while the bamboo forest growth is relatively poor in Songming county of Yunnan province,with the annual shoot yield at only 10.93 t/ha.Forest management measures also affect the growth of D.brandisii cv.songmingensis.The measures like overall soil preparation,watering once a month in the dry season with the watering amount at 900 kg/cluster,applying a large amount of organic fertilizer during afforestation and applying appropriate amount of NPK compound fertilizer(500 g/cluster)during the shooting peak period can promote the growth of bamboo forest and improve the yield and quality of bamboo shoots.
