摘要: 探究‘翠薏1号’烟后种植不同栽培密度与施肥水平对产量及构成因素的影响,选出其高产栽培最优组合。采用L16(45)正交设计随机区组排列田间试验方法,小区面积32 m2,根据生长期进行田间管理,采集有关生长数据,全区收获测产验收。结果表明:栽培密度、施肥水平、栽培密度与施肥水平互作对‘翠薏1号’产量差异极显著。在一定范围内,随着栽培密度的加大和施肥水平的提高,产量也相应的提高,但超出范围栽植过密,施肥水平过高,产量反而降低。产量构成4个因素中,对产量的直接贡献依次顺序为有效株数>每株粒数>结实率>百粒重。‘翠薏1号’在有效株数与每株粒数、结实率、百粒重之间存在明显的相互影响关系。每公顷栽培密度3.0万丛~3.6万丛与施N 225 kg、P2O5 112.5 kg、k2O 225 kg搭配,配套其他高产栽培技术,产量可达4600 kg以上。

Abstract: The aims were to study the effect of different planting density and fertilization level on the yield and component factors of ‘Cui Yi No.1’ after planting tobacco, and select the optimal combination of high yield cultivation. L16(45) orthogonal design randomized block arrangement field experiment method was used in the 32 m2 residential area. Field management was carried out according to the growth stage, and related growth data was collected, the harvest yield was checked and accepted. The results showed that, fertilization level, and both of them interaction on yield of ‘Cui Yi No.1’ had significant differences. In a certain range, with the increase of planting density and fertilization level increased, the yield was also increased correspondingly, but beyond the scope of dense planting, fertilization level was too high, the yield decreased., the direct contribution to the yield in the 4 factors of yield components, was as follows: the effective plant number> grain number per plant > setting seeds rate > 100 grain weight. There are obvious mutual influence relations among the effective plant number, grain number per plant, setting seeds rate, and 100 grain weight of ‘Cui Yi No.1’. Every hectare planting density 30000 plexus-36000 plexus with N 225 kg, P2O5 112.5 kg, k2O 225 kg collocation, adding other high-yield cultivation technique, the yield could reach more than 4600 kg.
