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1～2g·kg-1的CaCl2或CaSO4,竹山茶园土壤中可施加3～5g·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1.5～2g·kg-1的CaCO3或CaO,也可施加3～4g·kg-1的Ca3(PO4)2.杭州茶园土壤中可施加4～5g·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.
Taking the tea plantations of Yingshan, Dawu, Zhushan, Chibi and Hangzhou as examples, the water-soluble fluorine content in soil was controlled by applying a certain amount of CaCO3, CaO, Ca3 (PO4) 2, CaCl2 and CaSO4. A certain amount of CaCl2 or CaSO4 could reduce the content of water-soluble fluorine in the soil of Mountain, Dawu and Zhushan tea plantation, and CaCl2 or CaSO4 of 1-2 g · kg-1 could be applied to the soil of Yingshan and Dawu tea, 3 ~ 5g · kg-1 CaCl2 or CaSO4 can be applied, but the application of CaCl2 is better than CaSO4 in the three kinds of tea plantation soils, CaCO3, CaO and Ca3 (PO4) 2 increase the content of water-soluble fluoride Content of CaCl2, CaO or Ca3 (PO4) 2 in the tea plantation soils of Chibi and Hangzhou can reduce the content of water-soluble fluorine in the soil, and 1.5-2 g · kg-1 of CaCO3 or CaO in the tea plantation of Chibi could also be applied 3 ~ 4g · kg-1 Ca3 (PO4) 2 can be applied in the tea plantation soils, 4 ~ 5g · kg-1 CaCO3 or CaO or Ca3 (PO4) 2 can be applied in Hangzhou tea plantation soils Which is better than CaO and Ca3 (PO4) 2, while the application of CaCl2 and CaSO4 in these soils significantly increased the content of water-soluble fluorine content.
