内蒙古杭锦旗有一位普通牧民,他把普通的瓶子灌满清水,插入红柳树苗,用泥土密封起来,然后埋到沙丘中。不久,树苗便会从瓶口外的茎干上溢出根须扎进沙层,待水耗尽,根须已足能供养树苗成活。 There is an ordinary herdsman in Hangjin Banner, Inner Mongolia. He fills an ordinary bottle with clear water, inserts the willow saplings, seals them with mud, and then buries them in sand dunes. Soon, the saplings will spill out of the roots of the stems and plunge into the sand until the water is exhausted. The roots are already sufficient to sustain the seedlings.
