摘要
对柞木段和生长过木耳一年、二年和三年后的柞木段,进行了化学组成分析.结果表明:其可燃性组成抽提物、综纤维素的含量逐年下降;而难燃性组成木素和灰分含量不断增加.从而导致生长过木耳后的柞木段难燃.文中提出在柞树林中将抚育采伐枝桠和采伐剩余物埋成堆,接上木耳菌,既可作为防火隔离带,又起到保持水土,保持土壤中营养元素的作用.
The chemical composition of oak segments on which an edible fungues(Auricularia auricula-judae) had grown for one year, two years or three year wasanalyzed. It was found that the content of the combustible composition-extractives and holocellulose in the oak segments came down year by year, andthe content of incombustible compostion-lignin and ash increased continuously.Therefore, the oak segments become incombustible after edible fungues grew onthem. The authors suggests that the branch and residues that may be producedby tending cut should be collected and piled up, then the edible fungues inoculat-es on them. They not only can be used as firebreak zone, but can preserve waterand soil, and in soil nutrient. So it has profound economic significance.
