萝卜生长期短 ,产量高 ,在整个生育期中吸收无机营养成分较多 ,其中吸收钾最多 ,氮次之 ,磷较少。据试验 ,每株萝卜 (济南青圆脆 )全生育期需要Ｋ2 Ｏ7.32 ｇ、Ｐ2 Ｏ52 2 0ｇ、Ｎ2 .88ｇ。萝卜苗期对钾的吸收量只占总吸收量的 1 5%以下 ,所吸收的 85%以上的钾素是在肉质根膨
Radish growth period is short, high yield, absorption of inorganic nutrients throughout the growing period more, of which the most absorbed potassium, followed by nitrogen, phosphorus less. According to the test, each plant radish (Jinan green crisp) the whole growth period needs K2 O7.32 g, P2 O52 20g, N2. Radish seedling stage of potassium absorption of only 15% of the total absorption below the absorption of more than 85% of potassium in the fleshy root swelling
