对实验中心范围内红椎林分的生长调查表明：红椎的生长受立地条件的影响较大；在土层深厚、肥沃的土壤上种植，其生长明显优于土层浅薄、贫瘠的土壤；在坡积土上的生长显著优于原积土。在同一个坡面上，７ 年生红椎林，下坡蓄积达１０７．８０ ｍ ３·ｈｍ － ２，而上坡仅为１６．６３ ｍ ３·ｈｍ － ２。红椎的生长也受海拔的影响，在母岩、土壤、地位指数相同的条件下，红椎在低海拔的生长优于高海拔。栽培模式对红椎的生长也有影响，营造混交林能促进红椎的生长，且以异龄混交为优；混交比例不同生长亦有异，６年生红椎与马尾松不同比例混交试验显示，红椎与马尾松按１∶６ 混交，红椎生长最好，其胸径生长量与红椎纯林比达到显著差异，树高生长量比纯林高８．２％ ，林分蓄积量高１３８．９％ ，但从生产经营目标和混交林效益综合考虑，按１∶４ 混交更利于红椎作为目的树种培育成大径材 The investigation on the growth of red vertex in the experimental center shows that the growth of red vertebra is greatly affected by the site conditions. When grown on deep and fertile soil, the growth of red vertebra is obviously better than the shallow and infertile soil. The growth on the slope soil is significantly better than the original soil. On the same slope, the 7 - year - old red vertebral forest had a downhill accumulation of 107.80 m 3 · hm - 2 and a uphill slope of only 16.63 m 3 · hm - 2. The growth of red vertebra is also affected by altitude. Under the condition of the same parent rock, soil and status index, the growth of red vertebra at low altitude is better than that of high altitude. Cultivation mode also has an impact on the growth of red vertebra, to create a mixed forest can promote the growth of red vertebra, and mixed with heterosis is superior; mixed growth also vary, 6 years of red vertebral and Masson pine different proportions showed that red Verticillium and Pinus massoniana mixed by 1: 6, the best growth of red vertebrae, the DBH growth compared with the pure red forest to achieve significant differences, the growth of tree height 8.2% higher than pure forest, stand volume 138 high. 9%, but from the production and management objectives and the benefits of mixed forest comprehensive consideration, mixed by 1: 4 more conducive to red vertebrate as a target tree species to grow into large diameter timber
