摘要
[目的]研究绿肥翻压还田对烟叶生产发育指标和产量产值的影响。[方法]2014年5～9月在陕西省汉中市洋县进行田间小区试验，采用绿肥翻压不减氮、绿肥翻压减氮相结合的方法，分别研究了黑麦草和紫花苕子两种绿肥类型、不同翻压量对烤烟生长发育和产量产值的影响。[结果]绿肥翻压处理在团棵期烟株的生长发育情况不如常规施肥处理，而旺长期和成熟期烟株的长势较常规处理好。黑麦草翻压处理在促进烟株长势，提高烟叶产量产值，提升上等烟比例及单叶重的效果优于紫花苕子。绿肥翻压不减氮处理较减氮处理更有利于提高烟株的农艺性状、产量、产值及经济学性状。[结论]常规施肥＋黑麦草翻压30000 kg／hm2或常规施肥＋黑麦草翻压52500 kg／hm2减氮26．25 kg／hm2处理效果好，适合在汉中地区的地形和气候条件下种植。
Abstract
Objective] To study the effects of green manure returning on tobacco leaf development index,yield and output value.[Method] Form May to September in 2014,in Yang County of Hanzhoung City of Shanxi Province,a field experiment was conducted to study the effects of Vicia villosa and ryegrass green manure types and ploughing returning amount on tobacco leaf development ,yield and output value.[Result] The growth of tobacco plants in rosette period treated by green manure ploughing returning was not as good as conventional fertilization treatment , growth potential of tobacco plants in vigorous period and mature period was better than that in conventional fertilization treatment .Ryegrass was superior than Vicia villosa in promoting tobacco growth potential,improving tobacco yield,output value,upper grade tobacco proportion and single leaf weight.Green manure ploughing returning without nitrogen reduction was more favorable for agronomic traits ,yield,output value and econom-ic traits of tobacco.[Conclusion] The conventional fertilization of ryegrass application 30 000 kg/hm2 or conventional fertilization of ryegrass ap-plication 52 500 kg/hm2 +reduced nitrogen 26.25 kg/hm2 treatment effect is good,suitable for cultivation in the local topography and climate conditions.
