Chinese. 试验研究了钾肥不同施用量对嘉定白蒜植株生长、蒜头产量和商品性的影响。结果表明：提高钾肥施用量可以促进大蒜植株的生长并保持植株健壮，这种作用在生长后期更加明显。随着钾肥施用量增加，大蒜蒜头总产量和商品蒜头产量显著提高，裂蒜和小蒜百分率明显降低。最佳钾肥施用量按K2O计为12～18kg/666.7m. 。

The results indicated that a high K application could favor plant growth and maintain it strong. Such action was more obvious at the later stage of plant growth. As potassium fertilizer application increased, both the total yield and commodity garlic yield increased significantly, on the oontrary, the percentage of dehiscent garlic and small garlic reduced distinctly. The optimum amount of potassium fertilizer （K2O） applied was 12～18 kg/666.7m. .
