不同施肥水平對中煙100產(chǎn)質(zhì)量的影響
Effect of Fertilizer Rates on Yield and Quality of Zhongyan100

摘要: 為了確定中煙100合適的施肥水平及煙葉產(chǎn)量,,通過1年2地點(山東沂水,、費縣)的田間試驗,研究了高,、中,、低及零肥量對中煙100產(chǎn)量和質(zhì)量的影響。結(jié)果表明,,煙葉產(chǎn)量,、均價等隨施肥量的增加而提高,當(dāng)施氮量達到105 kg/666.7m2時,,上等煙比例和均價最高,;高肥力下施氮75 kg/hm2,、中等肥力下施氮142.5 kg/hm2時,,煙葉感官質(zhì)量最佳;中煙100需要較高的營養(yǎng)供應(yīng)水平,,獲得較佳質(zhì)量的產(chǎn)量低限為2250 kg/hm2,。Abstract: Field experiments at two locations (Yishui and Feixian of Shandong Province) were conducted to investigate the effect of fertilizer application rates(high, medium, low, and null) on tobacco (var. zhongyan100) leaf yield and quality. The results showed that tobacco leaf yield and average price increased with the increase of fertilizer application levels. The superior leaf proportion and average price reached highest under the nitrogen level of 105 kg/ha. The best smoking test results were observed when nitrogen rate was 75 and 142.5 kg/ha for high and middle fertile soils, respectively. The results suggested that Zhongyan100 required high level of nutrient supply. To produce higher quality tobacco, the minimum yield of Zhongyan100 should be 2 250 kg/ha.
