- 摘要：以湖北英山、大悟、竹山、赤壁和浙江杭州茶园土壤为研究对象,通过施加一定量的CaCO3、CaO、Ca3(PO4)2、CaCl2 和CaSO4来调控土壤中水溶性氟含量,结果表明:英山、大悟和竹山茶园土壤中施加一定量的CaCl2 或CaSO4均可降低土壤中水溶性氟含量,英山和大悟茶园土壤中可施加1~2 g · kg-1的CaCl2 或CaSO4,竹山茶园土壤中可施加3~5 g · kg-1的CaCl2 或CaSO4,但3种茶园土壤中施用CaCl2 的效果比CaSO4好,而这些土壤中施加CaCO3、CaO和Ca3(PO4)2则显著增加土壤中水溶性氟含量.赤壁和杭州茶园土壤中施加一定量的CaCO3、CaO或Ca3(PO4)2均可降低土壤中水溶性氟含量,赤壁茶园土壤中可施加1.5~2 g · kg-1的CaCO3 或CaO,也可施加3~4 g · kg-1的Ca3(PO4)2.杭州茶园土壤中可施加4~5 g · kg-1的CaCO3 或CaO或Ca3(PO4)2.赤壁和杭州茶园土壤中施用CaCO3的效果比CaO和Ca3(PO4)2好,而这些土壤中施加CaCl2 和CaSO4则显著增加土壤中水溶性氟含量.
- Abstract：Calcium-containing materials including CaCO3, CaO, Ca3(PO4)2, CaCl2 and CaSO4 were used to regulate water-soluble fluoride in tea garden soils collected from Yingshan, Dawu, Zhushan, and Chibi of Hubei province and Hangzhou of Zhejiang province. The results indicated that the content of water-soluble fluoride in soils of Yingshan, Dawu and Zhushan decreased after application of CaCl2 and CaSO4, and the effect of applying CaCl2 was better than that of CaSO4. The appropriate amount was 1~2 g · kg-1 of CaCl2 or CaSO4 in soils of Yingshan and Dawu, and 3~5 g · kg-1 of CaCl2 or CaSO4 in the soil of Zhushan. The content of water-soluble fluoride in soils of Chibi and Hangzhou decreased by applying CaCO3, CaO or Ca3(PO4)2, and the appropriate amount for the soil of Chibi was 1.5~2 g · kg-1 of CaCO3 or CaO or 3~4 g · kg-1 of Ca3(PO4)2, while for the soil of Hangzhou was 4~5 g · kg-1 of CaCO3, CaO or Ca3(PO4)2. The effect of applying CaCO3 was better than that of CaO and Ca3(PO4)2 on the soils of Chibi and Hangzhou, however, the content of water-soluble fluoride in these two soils increased after applying CaCl2 or CaSO4.
