摘要:

为降低烟叶含梗率,提高烟叶工业价值,以‘云烟105’为试验材料,运用正交试验设计,研究了纯氮量、株距、封顶时间及留叶数4个因素组合对烟叶含梗率的影响,并分析土壤养分与含梗率关系。结果表明,降低烟叶含梗率的最优方案为施纯氮量82.5 kg/hm2、株距55 cm、现蕾封顶和留叶数22片,其中影响因素的主次顺序为封顶时间>株距>施纯氮量>留叶数,主因素封顶时间所占权重为0.6219。烟叶含梗率与土壤全磷含量和pH呈显著相关性,回归方程为Y=-130.839+18.486X4+22.112X1X4代表全磷含量,X1代表pH)。栽培因素的优方案组合可有效降低‘云烟105’的含梗率,且发现土壤全磷含量和pH对‘云烟105’的含梗率有显著影响。

Abstract:

To reduce the stem ratio and improve the industrial value of tobacco leaves, taking ‘Yunyan 105’ as the experimental material, the orthogonal test design was used to study the effects of four factors, including pure nitrogen amount, plant spacing, topping time and number of leaves remained, on the stem ratio of tobacco leaves, and to analyze the relationship between soil nutrients and stem ratio. The results showed that the optimal scheme to reduce the stem ratio of tobacco leaves was 82.5 kg/hm2 of pure nitrogen application, 55 cm of plant spacing, topping at bud emergence and 22 leaves remained. The primary and secondary order of the influencing factors was topping time> plant spacing > pure nitrogen application amount > number of leaves remained, and the weight of topping time, which was the primary factor, was 0.6219. Soil pH and total soil phosphorus content were significantly correlated with tobacco stem ratio, and the regression equation was Y=-130.839+18.486X4+22.112X1 (X4 was total phosphorus content, and X1 was pH value). The optimal scheme of cultivation factors can effectively reduce the stem ratio of ‘Yunyan 105’, and soil total phosphorus content and pH value have significant effects on the stem ratio of ‘Yunyan 105’.
