摘要:
为解析甘薯生长的水钾耦合效应,科学调配水分和钾素以提高甘薯的产量和水分利用率,进行了可控的水分、钾素二因子盆栽试验。水分因子设3个水平:田间最大持水量的50%(W50)、田间最大持水量的75%(W75)、田间最大持水量的100%(W100);钾肥因子设3个水平(以风干土中施K2O含量计):0 mg/kg(K0)、150 mg/kg(K150)、300 mg/kg(K300)。结果表明水分和钾素间表现出显著的耦合效应。在本研究条件下,甘薯在W75-K150下块根产量最大,其水分利用效率最高。对于水分利用效率,在干旱条件下(W50),钾素与土壤水分表现为拮抗效应,而当正常供水时(W75),施钾可以缓解由于土壤水分提高而造成的水资源浪费现象。在充分灌溉条件下(W100),产量的提高是以水和肥投入为代价的,应该适当控制水肥的投入。结合块根产量和水分利用效率分析,以W75-K150处理的水钾配比较为合适。
Abstract:
To analyze the coupling effects of water and potassium on the growth of sweet potato, and to increase the yield and water use efficiency of sweet potato by scientifically regulating water and potassium, the pot experiments with controllable water and potassium factors were conducted. Three levels for the factor of water were designed: 50% of field moisture capacity (W50), 75% of field moisture capacity (W75), 100% of field moisture capacity (W100). Three levels for the factor of K were designed (by the content of K2O in 1 kg dry soil): 0 mg/kg (K0), 150 mg/kg (K150), 300 mg/kg (K300). Results showed that there were significant coupling effects between water and potassium. In the study, sweet potato under W75-K150 treatment obtained the highest root yield, and its water use efficiency was higher than others. Potassium and soil moisture showed antagonistic effect on water use efficiency under drought condition, while, the application of potassium would relieve the water loss caused by the increasing water condition with normal water condition. In the sufficient water condition, the high yield sacrificed with the controlled inputs of water and fertilizer. Combined the results of yield with water use efficiency, the treatment of W75-K150 was appropriate to produce sweet potato.
