不同施氮水平对湘南稻作烤烟生长发育和经济性状的影响OACSTPCD
Effects of Different Nitrogen Levels on Growth, Development and Economic Character of Flue-cured Tobacco Planted in Paddy in South Hunan
为明确郴州欧阳海基地单元稻作烤烟的施氮量，调查分析了3种施氮水平下的烤烟农艺性状、干物质积累和经济性状。结果表明：（1）较高的施氮量对烟株生长有一定的促进作用，烤烟生长优势较明显。（2）较高的施氮量不利于上等烟比例的提高，但由于其产量高，产值也高。（3）兼顾烟叶产量和产值及生产成本，郴州欧阳海基地单元稻作烤烟施氮量水平应控制在150 kg／hm2为好。
Investigation and analysis of agronomic trait,dry matter accumulation and economic character of flue-cured to-bacco were made under 3-types nitrogen application rate to explicit the suitable nitrogen levels in Ouyanghai base of Chenz-hou.The results showed that:(1)higher nitrogen application rate can promote tobacco growth obviously.(2)higher nitro-gen application rate goes against increasing the fine tobacco ratio,but its yield and out-put value are more th…查看全部>>
