通过对不同混交比例的香椿湿地松混交林与香椿、湿地松纯林的生长比较,并进行成效分析研究。结果表明:香椿与湿地松混交后,不同的混交比例,其生长量不同,在混交比例为1:2时,香椿湿地松生长量明显提高;在混交比例为1:1时,香椿的生长量提高,而湿地松的生长量受到影响。香椿湿地松以适当的比例进行混交造林,因种间关系协调,改善了林内的生态环境条件,促进了林木生长,且混交比例在1:2时,其生长效果佳,是闽东沿海山地理想的一种高产稳定、生态协调的人工针阔混交林类型。
通過對不同混交比例的香椿濕地鬆混交林與香椿、濕地鬆純林的生長比較,併進行成效分析研究。結果錶明:香椿與濕地鬆混交後,不同的混交比例,其生長量不同,在混交比例為1:2時,香椿濕地鬆生長量明顯提高;在混交比例為1:1時,香椿的生長量提高,而濕地鬆的生長量受到影響。香椿濕地鬆以適噹的比例進行混交造林,因種間關繫協調,改善瞭林內的生態環境條件,促進瞭林木生長,且混交比例在1:2時,其生長效果佳,是閩東沿海山地理想的一種高產穩定、生態協調的人工針闊混交林類型。

Growth for mixed forest of Toona sinensis & Pinus elliottii with different mixed proportion and growth of pure forest of Toona sinensis & Pinus elliottii were compared;their growth effect analysis were studied. Result shows that: growth of mixed forest of Toona sinensis & Pinus elliottii with different mixed proportion is different. Growth of Toona sinensis & Pinus elliottii are significantly improved while mixed ratio being 1: 2 ; growth of Toona sinensis was improved with the mixed ratio being 1 : 1, and growth of Pinus elliottii was affected. Toona sinensis & Pinus elliottii were mixed with appropriate proportion ; due to the coordinated interspecific interactions, ecological conditions of the forest were improved , and growth of forest stand were promoted;the growth effect was optimal while the mixed ratio is 1: 2;it is a high-yield, steady & ecological harmonious mixed plantation of conifer and broadleaf in coastal mountainous region of eastern Fujian.
