为解决金花茶(Camellia nitidissima)产品原料短缺问题,提高马尾松林(Pinus massoniana)地利用率和产出率,于2014年6月至2016年5月在桂东岑溪市紫胶林场开展了马尾松密度×金花茶密度双因素随机区组试验。研究结果表明:金花茶造林适合的株数密度随马尾松株数密度递增呈增大的趋势,300株/hm~2(郁闭度0.4~0.45)马尾松林下适合种植金花茶密度要控制在1 665株/hm~2以下,450株/hm~2(郁闭度0.5~0.6)马尾松林下适合种植金花茶密度控制在1 665~2 505株/hm~2,600株/hm~2(0.6~0.7)马尾松林下适合种植金花茶密度控制在2 505~3 330株/hm~2;金花茶生长区组间的差异达到显著水平,位于中坡金花茶要比上坡金花茶生长好;在桂东地区12月至次年2月金花茶生长基本停滞,金花茶施肥适宜安排在3-9月。
In order to solve the shortage of raw materials of Camellia nitidissima products and improve the utilization rate and yield of Pinus massoniana, from June 2014 to May 2016, masson pine Density × golden tea density two-factor randomized block test. The results showed that the suitable number density of A. polygamous afforestation tended to increase with the increase of the number density of P. massoniana, and the density suitable for planting S. miltiorrhiza in 300 plants / hm 2 (canopy density 0.4-0.45) Planting density under control of Pinus massoniana plantations of 1 665 ~ 2 505 plants / hm ~ 2,600 plants / hm ~ 2 (0.6 ~ 0.7 The density of the golden camellia suitable for planting under the Pinus massoniana forest was controlled at 2 505-3 330 a / hm 2, and the difference between the two groups reached a significant level. East from December to February next year Camellia growth basically stagnant, Camellia sinensis fertilizer suitable arrangements in March-September.
