| 摘 要： | 为探讨烤烟新品种豫烟10号的优化栽培技术,并提供可量化的具体指标,采用L9(34)正交试验设计,研究了种植密度、施氮量和单株留叶数对烤烟产值的影响。单因子效应分析表明,产值随着种植密度增加而增加,随着氮肥施用量的增加呈先增加后降低的趋势,随着单株留叶数的增加呈降低趋势;双因素交互效应表明,施氮量和单株留叶数之间的互作效应对产值影响最大,产值最高可达50 217.51元/hm~2。对产值的数学模型进行模拟寻优,结果显示,豫烟10号产值达到48 500元/hm~2以上的优化栽培措施组合指标为:种植密度18 718~19 495株/hm~2、施氮量47.34~74.75kg/hm~2、留叶数19~23片/株。

| Abstract: | In order to provide quantity index to optimum cultivation measures of new flue-cured tobacco variety Yuyan No. 10, L9 ( 34 ) orthogonal experiments were set with three factors of planting density, nitrogen rate,remained leaf number and three levels,to study the effects of the three factors on the output value of tobacco. Single-factor analysis showed that the output value of tobacco increased with the increase of the planting density, first increased and then decreased with the increase of the nitrogen rate, and decreased steadily with the increase of remained leaf number. Two-factor interaction analysis indicated that the interaction between remained leaf number and nitrogen rate affected the output value most. The output value could reach 50217. 51 RMB/ha. The optimized cultivation indexes with the output value of Yuyan No. 10 more than 48500 RMB/ha were 18718—19495 plants/ha of planting density,47. 34—74. 75 kg/ha of nitrogen rate,19—23 pieces/plant of remained leaf number. |
