不同品种、施氮量、种植密度对烤烟农艺性状、经济性状和化学品质的影响OA北大核心CSCDCSTPCD
Effects of Different Varieties,Nitrogen Rate and Planting Density on Grow th,Economic Characters and Chemical Quality of Flue-cured Tobacco
为探讨适宜豫西烟区的烤烟主栽品种以及烤烟最佳的种植密度和施氮量，采用正交试验设计，通过田间小区试验，研究了不同品种、施氮量和种植密度对烤烟农艺性状、经济性状和化学品质的影响。结果表明：在移栽后35 d ，以中烟100品种株高最高，不同密度水平烤烟株高、茎围、叶片数和叶面积差异不显著；在移栽后60 d ，烤烟叶面积随施氮量的增加呈增加趋势。试验因素对产量的影响排序为品种＞施氮量＞密度，获得最高产量的组合为 A3 B3 C3（即品种为豫烟6号，密度1…查看全部>>
Using orthogonal experimental design for the field experiment ,the effects of different varieties ,nitrogen rate and planting density on grow th ,economic characters and chemical quality of flue-cured tobacco were studied in the west of Henan region to find the suitable cultivars and optimum nitrogen rate and planting density .The results showed that on the 35th day after trans-planting ,the plant height of Zhongyan 100 was highest among the 3 varieties and …查看全部>>
