几种商品有机肥在新烟区的对比试验

Comparative Experiments of Several Kinds of Commercial Organic Fertilizers in New Tobacco Areas

[目的]为探索商品有机肥在新烟区对烤烟的影响,筛选出适合红塔集团遮放烟叶基地单元使用的商品有机肥。[方法]对4种商品有机肥进行大面积对比试验示范,调查各处理烤烟主要大田生育期、农艺性状、经济性状,并且对初烤烟叶进行外观质量和内在化学成分检测分析。[结果]施用有机肥能够促进烟叶落黄成熟,缩短KRK26品种大田生育期,且能提高烟叶产值,提高初烤烟叶外观质量光泽度和烟叶产值量,初烤烟叶化学成分趋于协调。[结论]在几种商品有机肥中,李杨牌有机肥的总体表现较好,可以在基地单元作进一步试验示范。

[ Objective ] The research aimed to investigate the effects of commercial organic fertilizer on the production of tobacco in new tobac- co areas, and screen the preferable manure for the tobacco base units of Hongta Group. [ Method] Four kinds of commercial organic fertilizers ware tested in large area, and the investigation of main field growth stages, agronomic characteristics, economic characteristics of flue-cured tobacco leaves was made, and the appearance qualities and the intrinsic chemical components were detected. [ Result] The application of or- ganic fertilizers could promote the tobacco leaves yellow and mature, shorten the field growth stages of variety KRK26, improve the yield and quality, enhance the gloss of the initial flue-cured tobacco leaves, and the chemical composition was tend to be more coordinated. [ Conclu- sion ] The organic fertilizer of LIYANG Brand has better performance on the whole, which can be used for further experiments and demonstra- tions in the fields of tobacco base units.
