一、扁柏林叶的特性 关于扁柏及其林分的生物学特性,坂口氏(1952)、佐滕氏(1971)和四井氏等(1974)曾作过详尽的报导,这里不再赘述。本文所要论述的是关于扁柏林的落叶与地力的关系问题。 1.叶量干重:根据研究资料表明,扁柏林的叶量干重一般在10～19吨/公顷,为落叶树林的3—5倍,但比杉木林15—72吨/公顷要少,就是同其他常绿针叶树比较也是少的。如果从齐滕(秀)氏最近对尾鹫扁柏林调查结果来看,那就显得更少。他认为,有些扁柏林分叶量干重还没达到10吨/公顷。 2.落叶量:据测定,扁柏和其他树种一年内的落叶量是:落叶阔叶林3.2吨/公
The characteristics of the hinoki cymbidium Sakaguchi (1952), Zotten (1971) and Si Wells et al. (1974) have made detailed reports on the biological characteristics of the cypress and its stand, which are not repeated here. What this article addresses is the issue of the relationship between the deciduous and hinterland of the flat Berlin. Leaf dry weight: According to the research data shows that the flat leaf dry weight of leaves is generally 10 to 19 tons / hectare, deciduous forest is 3-5 times, but less than 15-72 tons / ha of Chinese fir forest, Is compared with other evergreen conifers is also less. If from the Qi Teng (show) recently, the findings of the survey of flatfish IWUZU, it seems even less. He believes that some of the flat-leaf Berlin dry weight has not yet reached 10 tons / hectare. 2. Deciduous quantity: According to the determination, the deciduous quantity of cypress and other tree species in one year is: Deciduous broad-leaved forest 3.2 tons /
