Bioblock技术在黔南喀斯特山区的造林试验

选用乡土树种柏木1年生苗,分别以Bioblock技术(以再循环瓦楞纸容器有盖品字排列、有盖单一排列、无盖单一排列)以及传统挖穴造林方式等4种不同造林方式在喀斯特山区进行造林试验;同时,选择乡土树种柏木、椤木石楠、苦楝、栾树、榆树、刺槐及大叶女贞等7个树种的1年生苗,以Bioblock技术(以再循环瓦楞纸容器有盖单一排列方式)在喀斯特山区进行造林试验。结果表明:不同造林方式及不同树种的造林成活率差异均显著。不同造林方式中造林成活率最高的是品字排列方式造林,成活率高达94.96%;最低的是传统挖穴方式造林,成活率只有20.20%。不同的树种,造林成活率最高的是柏木,达62.63%;其次是榆树,造林成活率为60.61%;最低的是苦楝和栾树,造林成活率均只有18.18%。

The afforestation experiment in karst mountains of Qiannan by Bioblock method

Used one-year-old tree species of Cupressus funebris Endl.as test meteral,which taking four different foresta-tions in karst mountain area of afforestation experiment by Bioblock method (treat in recycled corrugated container word alignment,with cover single permutation,and without cover single permutation)and traditional way of afforestation.At the same time,choosed one-year-old seven tree species of Cupressus funebris Endl.、Photinia davidsoniae Rehd.et Wils.、Melia azedarach Linn.、 Koelreuteria paniculata、 Ulmus pumila L.、 Black Locust、 Ligustrum compactum (Wall.ex G.Don) Hook.f.Tho.by Bioblck method (treat in recycled corrugated container with cover single permuta-tion)afforestation experiments were conducted in karst mountain areas.The result showed that there were a significant difference in Bioblck method ways with different tree species afforestation on survival rates.The best afforestation method is using paper containers which arranged in triangle and the survival rates is 94.95%,the bad afforestation method is tra-ditional way and the survival rates only have 20.20%.The hightest afforestation survival rate of tree species is Ulmus pumila L.and Cupressus funebris Endl.,which reached 62.63% and 60.61% respectively,and lowest is Melia azeda-rach Linn.and Koelreuteria paniculata of 18.18%.
