摘要：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
The investigation on Castanopsis hystrix in the range of the Experimental Centre show that the plant’s growth is greatly effected by site,the growth of the plants grow on deep soil layer is obviously better than those grow on shallow poor layer,those growing on the soil accumulated with fertile soil on the slope are better than those on original soil.At the same slope for the same plant,at its lower slope the volume reached 107.80 m 3·hm -2 ,while its upper slope,16.63 m 3·hm -2 .The growth of the plant is also affected by the altitude,mixed stand is better than pure stand.The stand with 1∶6 mixed ratio( C.hystrix∶Pinus massoniana ),the plant grow the better,its DBH volume is obviously greater than that of the pure stand, its tree height is 8.2% higher than the pure stand,stand volume is 138.9% higher. After all,1∶4 mixed ratio is better for the plant’s management.
