这绝不是“天方夜谭”:一拃之长、拇指之粗的一节枝杆插入土壤,一年之内,便可长成高达7米、直径可达4厘米的一棵茁壮的树。这种被科技界称为“速生杨”的树,稠密的树叶成簇成团,葱嫩丰满,大若梧桐树叶,棵棵树干笔直挺拔。据专家介绍,其单位生物积累量是一般栽培方法的普通杨树的20倍。 This is by no means “a fairy tale”: a long time ago, the thumb of a thick stick inserted into the soil, within a year, can grow up to 7 meters up to 4 cm in diameter a robust tree. This is the science and technology community called “poplar” tree, dense clusters of clusters of leaves, onions plump, large sycamore leaves, tree trunk straight upright. According to experts, the unit of bio-accumulation is 20 times the normal cultivation methods of poplar.
