为确定适宜贵州省独山县晒红烟品种小包耳的栽培技术,通过开展4个施肥水平即氮肥用量5.5、6.5、7.5、8.5 kg/667 m2和3个种植密度1 050、1 350、1 550株/667 m2水平产量产值的对比试验,研究分析2因素7个水平产量、产值间的差异。结果表明,产量最高的是667 m2施纯氮8.5 kg和种植密度为1 550株的小区,667 m2施纯氮5.5 kg和种植密度1 050株的小区产量最低;产值最高的是667 m2施纯氮6.5 kg和种植密度为1 550株的小区,667 m2施纯氮8.5 kg和种植密度1 050株的小区产值最低。由此得出,影响产量与产值最大的因素是密度,施肥量次之;在合理密度下(1 550株/667 m2),施肥量为6.5 kg/667 m2时所取得的产值最高。
In order to determine the appropriate cultivation techniques for the small ear of sun-cured tobacco varieties in Dushan County, Guizhou Province, four fertilizer levels, ie, 5.5, 6.5, 7.5, 8.5 kg / 667 m2 and three planting densities of 1 050, 550/667 m2 horizontal output value of the comparative test, research and analysis of 2 factors and 7 levels of output, the difference between the output value. The results showed that the yield of the highest yield was 8.57 kg of pure nitrogen at 667 m2 and the plantation density was 1 550. The output of 667 m2 was 5.5 kg pure nitrogen and the density of 1050 plants was the lowest. The highest yield was 667 m2 Nitrogen 6.5 kg and planting density of 1 550 plants in the district, 667 m2 of pure nitrogen 8.5 kg and planting density of 1050 plants in the lowest value. It can be concluded that the most influencing factors of yield and output value are the density and the second is the amount of fertilizer; the highest output value is obtained when the fertilization amount is 6.5 kg / 667 m2 at a reasonable density (1 550/667 m2).
