摘    要:
采用盆栽试验方法,研究了褐土区不同施钾量对烤烟植物学性状和干物质积累的影响。结果表明:钾肥施用量大小对烤烟植物学性状总体上无明显的影响;在移栽后30~60 d期间,烟株根和茎的干物质重总体上均随钾肥施用量的增加而增加;在移栽后45 d和60 d时,均以施钾量为7.5 g/株处理的叶片干物质重最大。因此,最适宜的钾肥施用量为7.5g/株。

关 键 词:褐土  施钾量  烤烟  植物学性状  干物质积累

Abstract:
Pot experiments were carried out to study the effects of different potassium fertilizer application rates on the botanical characters and dry matter accumulation of flue-cured tobacco in brown soil region.The results showed that potassium fertilizer application rate generally had not significant influence on the botanical characters of flue-cured tobacco.The root and stem dry matter weight generally increased with the increase of potassium fertilizer application rate during 30~60 days after transplanting.On the 45th day and 60th day after transplanting,the leaf dry matter weight was the largest when the application rate of potassium fertilizer was 7.5 g/plant.Thus,7.5 g/plant was the optimal potassium fertilizer application rate.
Keywords:Brown soil  Potassium fertilizer application rate  Flue-cured tobacco  Botanical character  Dry matter accumulation
