香料烟栽培的突出特征是密度大,保证香料烟的大田密度是提高质量、稳定产量的重要手段.1987年前我县由于采用一宽行(行距0.66米)一窄行(行距0.33米)的栽植方式及挖穴法移栽,密度一直徘徊在4000株/亩左右,采用此种栽植方式,香料烟产质量低,不合要求.近年我县从栽植方式入手找出一种既能提高密度又便于农事操作的栽植方式;并从移栽方法上研究提高大田苗期成活率的措施.具体做法:
The prominent characteristic of the cultivation of aromatic tobacco is that the density is high, and the field density of the tobacco is guaranteed to be an important means to increase the quality and stabilize the output. Before 1987, due to the adoption of a narrow row (0.66 meters) and a narrow row (0.33 meters) Planting methods and digging hole method transplanting, the density has been hovering around 4,000 / acre, using this planting methods, spices smoke low quality, unqualified .In recent years, my county from the planting mode to find a way to increase both density Easy to farm operation planting method; and from the transplanting method to study the measures to improve the survival rate of field seedling.Methods:
