摘要
以东甜3号、东甜4号为材料,研究不同钾素用量对甜玉米可溶性糖及产量的影响。结果表明,施用钾肥对甜玉米子粒可溶性糖含量的形成与积累有显著作用,不施钾肥或过量施钾均会降低子粒可溶性糖的含量。结合最终产量指标得出,保证甜玉米高产质优的最佳K2O用量为150kg/hm2。
Dongtian3 and Dongtian4 were used to investigate effects of potassium application on soluble sugars and yields in sweet maize. The results showed that potassium application played a significant role in formation and accumulation for soluble sugars of sweet maize. Zero or excessive application of potassium could reduce the content of soluble sugars in sweet maize. To ensure high yield and quality,the optimal potassium application rate was 150kg/ hm^2 ( K2 O).
