摘要: 采用裂区设计,结合经济效果(ECI)指数法和偏(Eta)2效应量分析法,明确行距、种植密度及其互作效应对烤烟经济性状的影响。结果表明,行距110 cm (R1.1)处理的产值和ECI均高于行距100 cm (R1.0)处理。单叶重、上等烟比例随着种植密度增大而降低,即种植密度1.5万株·hm–2处理(D1.5)显著高于种植密度2.1万株·hm–2处理(D2.1);产量和产值则随着种植密度增大而提高,D2.1显著高于D1.5;ECI随着种植密度的增大先增后降,种植密度1.8万株·hm–2处理(D1.8)显著高于其他2处理。在行距和种植密度互作中,R1.1D1.5与R1.0D1.5处理的单叶重均显著高于R1.0D2.1与R1.1D2.1,其产量和产值均显著低于R1.0D2.1与R1.1D2.1。烤烟的ECI以R1.1D1.8最高,显著高于R1.0D1.5、R1.0D2.1和R1.1D2.1。行距对烤烟的经济性状指标的影响效应相对较低,但种植密度及行距和种植密度互作对烤烟的单叶重、上等烟比例、均价、产量、产值和ECI影响效应均较高。选择适宜的行距和种植密度有利于黔南山地烤烟经济性状的提升,在黔南山地植烟生态区,行距110 cm和种植密度1.8万株·hm–2是有利于实现烤烟优质适产的栽培配置。

Abstract: The research was conducted to determine the effects of row spacing, planting density and their interaction on the economic properties of flue-cured tobacco in southern Guizhou mountainous region. The field trial was conducted by split zone design along with the economic effect index (ECI) method and partial (Eta)2 effect analysis method. The results showed that output value and ECI of R1.1 treatment was higher than that of R1.0 treatment. Weight per leaf and first-class flue-cured tobacco ratio were reduced along with the increase of planting density, and those of D1.5 were significantly higher than D2.1. While the yield and output value of D2.1 were significantly higher than those of D1.5. The ECI was increased firstly and then decreased with the increase of planting density. So that of D1.8 was significantly higher than the other treatments. In the interaction between row spacing and planting density, the weight per leaf of R1.1D1.5 and R1.0D1.5 was significantly higher than that of R1.0D2.1 and R1.1D2.1, and the yield and output value were significantly lower than those of R1.0D2.1 and R1.1D2.1. The ECI of R1.1D1.8 was the highest and significantly higher than that in R1.0D1.5, R1.0D2.1 and R1.1D2.1. The effects of row spacing on the economic properties of flue-cured tobacco were relatively low, but the effects of planting density, interaction between row spacing and planting density on single leaf weight, proportion of superior tobacco, average price, yield, output value and ECI were higher. In conclusion, appropriate row spacing and planting density was conducive to the improvement of economic traits of flue-cured tobacco in southern Guizhou mountainous region. The planting density of 18000 plants·hm–2 combined with 110 cm row spacing was conducive to the realization of high quality and suitable yield of flue-cured tobacco cultivation in southern Guizhou mountainous region tobacco-planting ecological area.
