The children were all busy fitting the joints together and fastening them with little wooden pegs.

孩子们都忙着把这些关节装一起，栓固定。

He fastened it together with wooden pegs and made the four wheels out of short pieces of a big tree trunk.

栓钉合一起，一株大树的树干上切出了四片轮子。

And so it turns out that plants make this product, and it's called suberin.

果证明是植物制造了这种产品，它被称为栓质。

The peg was solid and firm in the door, but the hole in the stick was larger than the peg.

栓门上很实，但棍上的洞比栓大。

So the suberin will break up into little particles and give the whole soil a new texture.

所以栓质会分解成颗粒，并赋予整个土壤新的质地。

So that tells us we might be able to even combine within a trait and get even more suberin.

所以这告诉我们，我们甚至可以一个特合并获得更多的栓素。

Those are the three traits we want to change: more suberin, more roots, and the last one, deep roots.

这是我们想要改变的三个特：更多的栓质，更多的根，最后一个，深根。

And suberin is really cool, because as you can see there, I hope, everywhere you see a black dot, that's a carbon.

栓质真的很酷， 因为正如你那里看到的那样，我希望你看到的每个黑点都是碳。

We have to get plants to make more suberin than they normally make, because we need them to be a little better than what they are.

我们必须让植物产生比正常情况下更多的栓质，因为我们需要它们比现好一点。

The heavy wooden bolts began to roll in the house doors, and old Martin prepared to move, by gathering up his blue handkerchief, and reaching his bright knobbed walnut-tree stick from the corner.

沉重的栓开始房门上转动，老马丁准备移动，他收起他的蓝色手帕，从角落里伸手去拿他那根闪闪发亮的多节胡桃手杖。

We have to get them to make more roots, because if we make more roots, we can make more suberin -- now we have more of the cells that suberin likes to accumulate in.

我们必须让它们长出更多的根， 因为如果我们长出更多的根，我们就能制造出更多的栓质——现我们有了更多的细胞， 栓质喜欢其积累。
