本文講解了毛細床和魚菜共生結合的實例，有興趣的同學可以參考一下。 PS：很早就答應群友翻譯此文，無奈最近事情太多，一直到現在才完成，在此說聲抱歉。還有一篇姐妹文，我也會盡快翻譯出來，敬請關注。 原文鏈接：http://www./earthan-beds-how-they-go-together/ Earthan Beds – How they go together Earthan種植床——它們如何共生 One of the best aquaponic innovations to date,do it right and you will love it 這是最近關于魚菜共生的最好的發明之一，按照正确的方法做，你會愛上它的 
In response to many people wanting to knowhow I make the Earthan Beds work, here is a break down with a bit more detailon how to get it right when connecting them to your aquaponic system athome. The Earthan Bed is an incredibly effective growing combination forthose with aquaponic type gardens or grow fish. 很多人想知道我是如何使Earthan種植床發揮效能的，爲了回答這個問題，在這我披露一些細節，展示如何把它和你家的魚菜共生系統連接在一起。和魚菜共系統或有魚池的花園結合，Earthan種植床有着不可思議的效率。 
Earthan Beds – Organic Gardening at itsBest. Earthan種植床——有機花園的最佳形态 As you can see from the above picture theyare a very simple garden bed to build. I have said before, they aresimply a wicking bed created by Collin another ingeniousAustralian! Another way to think of them is a constant flow gravel bedwith a media barrier and topped with soil. Simple yes? 就像上面那張圖展示的那樣，構建這種花園是非常簡單的。如前所述，它們實際上就是由Collin——另一位富有創造力的澳洲人——發明的毛細床。換一種思路的話，也可以認爲它們就是在有持續流水的礫石床上加上基質隔離網并覆上土壤。是不是很簡單？ The abovedrawing has been modified from our builds to suit any grow bed/tank, be it on bessablocks raised or directly on the ground. If youare putting these directly on the ground as we build them with iron wrappedaround them, you will need to use a liner (preferably LDPE) and modify yourbottom fittings to suit. As you can see from the image below. 上面的示意圖是根據我們創建的實例，經過修改而畫成的，适合各種種植床和水槽，可以用百歲磚（也就是空心磚）墊高或直接建在地上。如果你和我們一樣把它們建在地上并用鐵皮圍起來，你需要鋪上防滲膜（最好是LDPE，也就是低密度聚乙烯），修整底部使之貼合。如下圖所示。 
If you are usinga liner, you will want the liner to come up the walls to just above the depthof the water so if they do get rained on they overflow. If you are usinga container that has a bottom such as a tank or trough, you will want anoverflow just above the water line if the beds are out in the rain. 如果你用防滲膜，注意要将防滲膜鋪至牆沿，比最高水位稍高，這樣水不會在下雨天溢出。如果你用一個有底容器比如水池或水槽的話，你需要個溢流裝置，這樣的種植床就可以放在室外了。 The depth ofeach layer does not appear to be significant, though depending on what soil youuse we have found 300mm of soil works well. The water comes to the top ofthe gravel, which can be any depth you like. I prefer to have a largevolume under the soil because the beds do generate significant amount of heatthrough the break down of nitrogen and carbon in the soil itself. 種植床各層的厚度不是很重要，這取決于你用哪種土壤，我們發現300毫米厚的土壤效果不錯。水會到達礫石的頂層，深度随你的喜好。我傾向于在土壤下面有較大的體積，因爲氮和碳在土壤裏分解的時候會産生大量的熱量。 
The gravelsubstrate can be almost anything at all. We use a large 40mm river mix(we did not clean it!). I have used 20mm blue metal drainage(BasinView) with great results but find the larger the gravel the betterthey flow. Especially over large distances in the earthan beds betweenthe inlet and outlet. We have never been concerned by vinegartesting the gravel and dont really mind if it contains some limestone as thebeds do need a large amount of carbon to get them ticking along correctly. Though avoid going out of your way to add limestone onmass. Stick with a large, smooth (for the sake of the liner) gravel orroad base and like I mentioned drainage gravel. 礫石層可以填入任何東西。我們使用比較大的40毫米混合卵石（我們沒有清洗它們！）。我曾經用過20毫米的青碎石（Basin View出産），效果很不錯，但我發現用更大的石頭會讓水流得更順暢。大顆的石頭尤其适用于種植床的入水口和排水口相距較遠的情況。我們從來沒有對碎石做過泡醋試驗，也不關心碎石裏是不是含有石灰石，即使種植床裏需要有大量的碳來抵消它們的影響。當然你還是應該避免主動添加大量的石灰石。用那些大顆的、光滑的（不易劃傷防滲膜）碎石或者路基石，還有我之前提到的排水青碎石。 On top of thegravel you will need some type of media barrier. We have used geotextilefabric in ours however during heavy rainfall, the beds wash down the soil fromthe surface and clog the fabric. I would look to a 70% shade clothto reduce the risk of this happening. It is not a great concern but ifyou have some of your water getting above the fabric it will overflow and yourun the risk of draining your system or worse flooding your beds… 在碎石層的上面你需要某種類型的基質隔離網。我們在系統裏鋪的是土工布，但是在下大雨的時候，表層的土壤會被沖洗下來，堵塞土工布。我嘗試用70%遮光的簾布來降低這種情況發生的概率。這不是個大問題，但如果你系統的水位高于隔離網的話，你的系統的排水可能會出問題，甚至水漫金山。 
I have found avery thick layer of cardboard on top of the media barrier, under the soil worksextremely well to keep the carbon level high. Keep in mind you arerunning nitrogen rich water from the fish through the bed constantly. Make the cardboard layer as thick as you like, even up to half the depth of thesoil. We gathered our cardboard from the local supermarket for freebundled up ready for the trailer. The cardboard layer in this gardenlasted about 6 months before it turned into a light and fluffy humus. Inthe mean time we had already added straw mulch to the surface which was coveredwith more soil as the original layer compacted down following the first crop. 我發現在隔離網的上面，土壤的下面鋪上很厚的一層硬紙闆能非常有效的保持碳量處于高位。記住在你的系統裏，富含氮的水不斷的從魚池流向種植床。硬紙闆層的厚度随你喜好，甚至可以占掉土壤層的一半高度。我從本地的超市收集硬紙闆，這些免費的硬紙闆已經捆好，準備被拖走。這種花園裏的硬紙闆層經過六個月後，會變沉輕質蓬松的腐殖質。同時我們還在土壤層的表面鋪上草蓋，然後在額外鋪上一層土壤，壓實後種上第一批作物。 
The soil mix isvery important (as is all of the media). Itend to avoid the straight up landscape suppliers “garden mix” or “premiumgarden mix” as they often come chocked up with fertilizer and animal wastes youmay not want in the garden at an early stage. Way too muchnitrogen in other words and remember there are fish swimming in this somewhere. My preference, if you have time and planned well, to make up yourown compost soil. If that is not available to you, some landscape guyswill mix the soil selection for you. 土壤的配制非常重要（即所有的基質）。我會避免直接使用園林供應商的所謂“花園土”或“優質花園土”，因爲它們裏面往往被混入了大量的肥料或動物糞便，這些都不适用于處于早期的花園。換句話說氮已經夠多的了，記住有很多魚正在系統的某個角落遊動呢。如果你有時間且安排得當的話，我的優先選擇是配制自己的堆肥土。若做不到，某些園藝師可以按你的要求配制土壤。 We have hadgreat success with 30% sand (loose not packing sand) and get the goodstuff, 30% mushroom compost and 30% quality garden soil. Squeezethe soil in your hand, if it clumps too much when you drop it, selectanother. To that we add a bag or so of shell grit to elevate the carbonlevels and offset the acid that forms through the microbes in the soil. 我們用30%沙子（松散而不是被壓實的）、30%菌菇堆肥（絕對的好東西）和30%高品質花園土混合，取得了很大的成功。把土放在你的手裏并握緊，松開手後如果結塊明顯，棄之。我們還加了一包壓碎的貝殼以提高含碳量，中和土壤微生物産生的酸。 The heat generatedwith a good soil mix makes them very suitable to cold climate growing regionswhere you use the fuel in the soil, in the grow bed, to help heat the waterrunning under it. If you want it warmer, add more nitrogen to get it toburn, while being conscience of the nitrogen:carbon ratios that are ideal forgrowing your plants. A C/N ratio of 20:1 will see you with a goodcomposting soil which will create excellent humus for your plant growth. 好的混合土會産生熱量，這非常适合寒冷地區，種植者可以利用這些熱量加熱系統裏的水。如果你想讓水更熱些，可以添加更多的氮來加速反應，隻要碳氮比适合你所種植的植物就行。20：1的碳氮比加上好的堆肥土能爲你的植物創造出極好的腐殖質。 
The surfacemulch is a really important step in building these Earthan Beds. It willhelp retain the heat and encourage the capillary action of the water throughthe soil and help prevent the surface from caking and drying out. Whileany type of mulch is great, sugar cane works very well as does Lucerne, thoughwe found there was no guarantee the lucerne did not come with its ownaccompaniment of weeds which shoot through later. Where as the sugar canemulch is usually burned before harvest and limits the opportunity to encourageweeds you do not want. The point of container gardening is to raise theheight but more importantly reduce the need for weeding. 表層的覆蓋物也是構建Earthan種植床的重要一環。它能幫助我們保溫，加強毛細作用，還能防止表層結塊和變幹。任何類型的覆蓋物都很棒，甘蔗和苜蓿一樣好，雖然我們發現苜蓿并不能确保雜草不會在之後冒出來。甘蔗在收割前往往會被焚燒，能夠限制雜草爆發。從容器的角度來看，提升高度更大的意義在于能使環境更加不适合雜草生長。 
You will want torun the system for a week before adding fish to the tank. The water willbe dirty but will clear up very quickly if you have your set up right. That will give you time to check the water parameters over the week to be sureit is satisfactory to your fish. If it is not right, avoid trying tochange it, the system will work it out one way or another. Just keep itrunning. There is no great need to “cycle” the system as the soil willcontain all the nitrifying microbes you can handle and will leach into thegravel substrate where your water flows very quickly. 你應該在加入魚之前先運行系統幾周時間。水會變髒，但很快就能被澄清，隻要你的系統設置正确。這樣也能讓你有充足的時間測試水質，确保魚能過得舒适。如果不行，别急着修改系統，系統會自我調整。隻要繼續運行即可。也沒有必要進行魚菜共生通常會做的“氮循環”，因爲土壤已經包含了各種硝化菌，它們會進入碎石層，在那裏，水會以比較高的流速通過。 And…the resultsspeak for themselves!
