学习如何堆肥 compost,如何制作一个蚯蚓之家 a worm farm,了解土壤【双语课程】3

同学们 my students,早上好 good morning,

今天 today 我们学堂的活动主题 the topic of our activity in our home school 是土地 is land,我想请 I would like to invite【】同学 () 和我们分享一下 share your opinion with us,什么是土地 what land is?

你能告诉我,can you tell me 为什么 why 土地 land 这么重要 is so important?

我再请问 I have another question,土地有生命吗 is land alive?你觉得 do you think 土地会呼吸吗 land breathes?就和我们人一样 just like us humans?

但是为什么 but why 一定要看到肚皮在起伏呢 do you have to see up and down of the belly? 植物也会呼吸 plants also breathe,它们就没有肚皮起伏 they do not have a belly, which has ups and downs。

那么今天 so today 我们要做一件什么事呢 what are we going to do?我们来养蚯蚓 we grow earth worms。

【】,你给我们说一说 can you tell us,蚯蚓是什么样子的 what do earthworms look like?

养蚯蚓 growing earthworms 不是为了钓鱼 is not for fishing,也不是去喂鸡 it is not for feeding chickens either,而是来观察一下 it helps us to observe,健康的土地是什么样子的 what healthy land is like。我们来思考一下 we will think,蚯蚓和健康的土地之间是什么关系 what kind of relationship is betwee earthworm and healthy land。

大家跟我来工具房 follow me to the tools room,带上你的 bring your 铲子 shovers、桶子 buckets、刀子 knives 、手套 gloves,大家去海棠苑里面 and we will go to the garden of caval vine。

老师先来解释一下 Let me explain,堆肥是什么意思 what compost is。堆肥 compost。

肥 ,就是肥料 Fei means fertilizers,是植物所需要的营养物质 they are nutritions that plants need,有两种肥料 there are two kinds of fertilizers,一种是工厂里面生产的化肥 one is the chemical fertilizer that is produced in factories,就是化学肥料 they are chemcal,还有一种是有机肥料 there is another kind which is organic fertilizer,主要是腐烂的植物和动物的粪便 mainly decaing plants and animal manue,今天 today 我们不需要 we do not need 动物的粪便 animal manue,只用植物的树枝树叶 only use plants’ branches and leaves 来做肥料 to make fertilizer。

蚯蚓 earthworms 和虫子 and bugs,还有微生物 and also microbes,将这些树枝树叶吃下去 eat these branches and leaves,排出来的粪便 their excrement,就是地上的植物最好的食物 is the best food for plants growing on land。是的 yes,植物喜欢吃动物的粪便 plants like to eat animal poop。

大家现在去捡树枝树叶 now please spread, and collect some branches/leaves,装在桶子里 put them in your buckets,然后倒在这里 and then throw them here,我们的蚯蚓之家就设在这个地方 our worm farm will be built right here。

为什么这里比较好呢 why is this spot good?因为这里比旁边要高一些 because it is a little higher than the surrounding area,下雨的时候 when it rains, 蚯蚓就不会被淹死 earthworms will not drown。

我们现在用铲子now use your shovel,把旁边的泥土扒过来 gather some top soil around here,堆在这些枯枝树叶上 on top of the decaying branches and leaves,这样风就不会把树叶吹走 so they will not be blown away。而且 And also, 蚯蚓来吃树叶的时候 when earthworms come to eat the leaves,就会暖和一些 it will be warmer,因为上面有泥巴盖着 because there is soil covered the food。

请大家伸出手 please show your hand,摸一摸这些泥巴 touch the soil,是不是太干燥了 isn’t it too dry?对了 right,请【】同学拿起你的桶子 (), please take your bucket,去那边提点水来 get some water from over there。

现在我们要插上标签 now we need to label it,上面 on it 写着 it will be written 我们都有谁 who we are,今天的日期 today’s date 等等 etc.,为什么 why 要这样做呢 are we doing this?因为 because 过一段时间 after a period of time 我们 we 或者其他人 or others 来看这堆肥时 come to check the compost,我们需要知道 we will need to know 从今天开始 from today,过了多少天 how many days have past,等到这些枯枝树叶 when all the decaying branches and leaves 都被蚯蚓和微生物吃光之后 have been eaten up by the worms and microbes,变成了土壤的一部分 and become part of the soil,我们需要知道 we will need to know 总共过了多少天 how many days have past in total,下次 next time 再堆肥的时候 when we make compost again 我们就有经验了 we will have some idea。

堆肥 compost 是有机种植和生态环境保护的关键一环 is a key element of organic farming and environment protection,也是减少城市垃圾的重要手段 it is also an important solution of reducing urban gabage。

大家回家后 when we return home,可以用厨余垃圾在阳台上 you may use the kitchen gabage, in your balcony,或者院子里 or in your yard, 自己尝试堆肥 try to make compost yourself,肥沃的土壤 fertile soil 可以用 may be used 来种菜 to plant vegetables、养花 and flowers。
