香椿两段式容器苗在喀斯特石漠化区域造林试验

为了检验香椿两段式容器苗在喀斯特石漠化区域造林的成活率、生长量表现情况。按试验设计,在贵州省金沙县马路乡犀牛村营造香椿容器苗示范林6.7hm2,作了与裸根苗造林的对照,对样方的成活株全面清点,求出成活率,用随机抽样抽取样株测量高生长量及径生长,对调查数据进行x2检验、T检验。结果表明,香椿两段式容器苗造林成活率、高生长量和径生长都显著优于裸根苗。为今后石漠化地区香椿造林开辟了新途径,亦是石漠化山区群众经济增长的一条捷径。

Container seedling of two-stage of toona sinensis in karst Rocky desertification region Study on the afforestation experiment of early

in order to examine the Chinese toon two section of type vessel seedling in the karst stone desert region afforestation survival rate,the growth meter present conditions situation.According to the experimental design,in the Guizhou Province Jinsha county street township rhinoceros village building Chinese toon vessel seedling demonstration forest 100 Chinese acres,has done with the truncated plant afforestation comparison,to a quadrat survival comprehensive inventory,extracts the survival rate,pulls out sample with the random sampling to survey the high growth quantity and the diameter grows,carries on the chi-squaretest,the T-test to the investigation data.After statistical analysis obtained,the Chinese toon two section of type vessel seedling survival rate of trees planted,the high growth quantity and the diameter grow all obviously surpass bare with the seedling.This research explores the Chinese toon vessel seedling to surpass the truncated plant in the stone desert region afforestation,opened the new way for the next stone desert area Chinese toon afforestation,also is a shortcut which the stone desert mountainous area populace economy grows.
