钾含量变化对无土栽培宝坻大蒜生长的影响

Effects of Nutrient Solution with Different Potassium Content on the Growth of Baodi Garlic in Soilless Culture

设置不同钾浓度的营养液处理,通过对宝坻大蒜植株长势和质量的观测,分析钾浓度变化对宝坻大蒜生长的影响。结果表明:基质栽培宝坻大蒜在不同浓度的钾含量的营养液处理后,其株高、茎粗、节间长及收获后的整株质量、地上部分质量、地下部分质量均有一定的差异,其中以钾浓度为234.59mg/L的营养液配方与其他处理差异最大,各项指标达到了最大值,说明钾浓度含量为234.59mg/L的营养液配方最适合宝坻大蒜的生长。

The objective of this work is to determine the effects of nutrient solution with different potassium on the growth of garlic. In this study, the height, cauloid diameter, internode length were measured during the growth of garlic seedlings. And, the seedlings weight, bulb weight and bulb diameter were surveyed after harvest. The results showed that the growth of garlic was influenced by potassium supply significantly, but there was no significant difference in bulb diameter of different treatments, and the recommended potassium concentration in nutrient solution was 234.59 mg/L in media culture of garlic.
