摘要
利用^(86)Rb作示踪剂进行盆栽,结合大田的小区试验,对向日葵合理施钾量的研究表明;在N、P肥为基础正常施量情况下,以每亩7.5—15公斤施钾量最佳,既能促进前期的生长发育,又能增加百粒重,提高产量。经方差分析达1％极显著水平。
Studies on optimal application of potassium in sunflower were carried out by86Rb in pots and plots of field.The results indicated that,under normal application of N and P,7.5-15kg/mu of potassium seemed to be the Optimal rates to accelerate growth and development,and increase 100-seed weight and yield,reaching 1 % of very significant levels by analysis of variance.
