广播电视英语短句 第 335 课：有机盖土-4

The same is true if compost is used for mulch. 如果用的是堆肥亦是如此。

Too much mulch can restrict oxygen and water flow to the soil and harm roots. 太多的盖土会阻止氧气和水流入土壤，同时还会对根系有害。

Also, do not build up mulch around the base of trees or plants like a volcano. 而且，不要把盖土在树或植物的底部位堆积得像火山口一样。

This could lead to disease or insect damage. 那会导致病害或昆虫危害。

Some gardeners use leaf mulch -- fine particles of leaves -- instead of wood mulch around trees, especially young trees. 有些园艺家在树木尤其是小树苗周围用树叶作盖土 — 树叶的细微粒物 — 代替木质盖土。
