对浙江省兰溪市茶场土壤研究结果表明，在四种垦用方式中，土壤养分来源除林地主要靠雨水外，旱地、桔园、茶园均主要来自化肥，其次是有机肥补给；四种垦用方式土壤养分收支皆有盈余，年均盈余量为茶园＞桔园＞旱地＞林地；土壤养分的消长趋势与土壤养分年均盈余量趋势基本一致。
The results of the research on tea plantation soil in Lanxi City, Zhejiang Province showed that in the four reclamation ways, the sources of soil nutrients mainly depend on rainwater except for the forest land. The dry land, the orange orchard and the tea plantation are mainly from fertilizer, followed by the organic fertilizer replenishment. In terms of soil nutrients, there was a surplus in the way of soil nutrient balance, and the average annual surplus was in the order of tea plantation> orange garden> dry land> woodland. The trend of soil nutrient decline and increase was consistent with the average annual surplus of soil nutrients.
