Abstract：In order to provide theoretical bases and technologies for saline-alkali soil reclamation and fertilizer application of cotton,the experiment was conducted with Bt cotton cultivar SCRC28 in coastal saline soil in the Yellow River Delta,Shandong Province.The effects of different amounts of silicon-calcium-potash fertilizer on the K+ and Na+ assimilation,chlorophyll content,dry matter accumulation and lint yield of cotton were investigated.The results showed that the K+uptake of cotton was obviously higher,and the Na+ uptake of cotton was obviously lower under the treatment with silicon-calcium-potash fertilizer as base fertilizer.The leaf area,chlorophyll content,stress resistance,dry matter accumulation and lint yield of cotton under the treatment of silicon-calcium-potash fertilizer application were also higher than those in corresponding controls.The lint yield under the treatment with 750 kg/hm2 of silicon-calcium-potash fertilizer added based on usual fertilizer amount increased by 6.9% significantly compared to the controls.It indicated that economic application of silicon-calcium-potash fertilizer played positive roles in saline-alkali soil reclamation,stress resistance improvement and lint yield increase of cotton in coastal saline fields.
