| Abstract: | The soil culture was used to study the effects of combined application of nitrogen and calcium on yield,calcium content of spinach and calcium content in soil.The results showed that under the experimental conditions,when the application rates of N and Ca were 0.2 g/kg and 0.3 g/kg respectively,the spinach biomass and Ca content of leaves were the highest and the contents of water-soluble Ca,exchangeable Ca and available Ca were higher in soil. |
