摘      要：ObjectiveThis study aimed to investigate the effect of the interactions among potassium （K）, calcium （Ca） and sodium （Na） on cabbage growth and nutrient absorption. MethodA total of 11 treatments with different levels of K, Ca and Na were set in the pot experiment to measure the nutrient content and uptake in cabbage plants. ResultThe use of K or the combined use of K and Ca improved the cabbage absorption on K and Ca. In addition, K and Ca presented an interaction as that appropriate amount of Ca promoted K uptake while excessive Ca inhibited the uptake. The treatment of Ca 2 K 3 with 0.33 g/pot of Ca and 0.67 g/pot of K could significantly increase the quantity of dry matter accumulation and absorption of Ca and K in cabbage, was the best among all treatments. ConclusionApplication of suitable amount of Ca could release the Na stress on cabbage growth at the low level of Na in soil.
