不同基追比对云烟87生长及产量的影响

Effects of Different Ratios between Basal Fertilizer and Top-Dressing on Growth and Yield of Yunyan 87

通过田间小区试验,研究不同基追比对云烟87生育期、农艺性状、经济性状的影响。结果表明,不同基追比对生育期有很大影响,随着追肥比例的增加,烤烟的生育期也逐渐增加;经济性状、上等烟比例以基、追肥比例6:4为最优。在该试验条件下,基追比为6:4的组合方法较适合云南省姚安县云烟87的优质生产。

A field experiment was carried out to study the effects of different ratios between basal fertilizer and top-dressing on growth period,agricultural characters and economic characters of Yunyan 87.The results showed that growth period increased with the increase of top-dressing ratio.When top-dressing ratio was increased,plant height and stem diameter increased,but economic characters and proportion of fair class leaf would be best at a proportion of 6∶4.The ratio between basal fertilizer and top-dressing at 6∶4 would be applied properly for Yunyan 87.
