sand-grass

The place felt pastoral, almost lush. Teh had to stop his car on the side of the highway and hike several minutes over dunes just to see where the wind-blown grass ended and the sand began.

那里一派田园风光，几乎可以说是草木茂盛。郑永仁不得不将车停在公路边，徒步走几分钟，翻过沙丘，才能看到在风中摇曳的草木与沙地接壤的地方。

At last they were on dry sand, and then on grass-a huge plain of very fine short grass, almost level with the Silver Sea and spreading in every direction without so much as a molehill.

终于走到干燥的沙地上，接着又走到草地上&好大一片草原，长着细细短短的草，几乎同银海一样高，向四面八方铺展开去，连个鼹鼠窠都没有。

The result indicated that grass and crop rotation improves aperture condition of soil, to improve the condition of much air draft and drought and sand, because of abstract ability of keeping water on the chernozem of bad water erosion and wind erosion.

结果表明：在水蚀和风蚀严重的岗平地黑土上实行草田轮作，有利于改善土壤的孔隙状况，从而改善岗平地黑土的通气有余、持水不足、易于干旱和沙化的状况。
