当前烤烟生产的首要任务是提高烟叶质量。影响烟株生长发育、产量高低、质量好坏的因素很多,在栽培技术方面合理选肥,科学施肥,是主要因素之一。为了探索烤烟优质高产与施肥的关系,我们于1978年进行了施肥量、施肥时间、施肥方法的试验研究。一、不同施肥水平与烤烟产质的关系试验在本院农场进行,试验地面积一市亩,黄壤,pH6.8—7.0,肥力中等,供试品种春雷三号,密度每亩为2500株,4月28日移栽,
The primary task of current flue-cured tobacco production is to improve the quality of tobacco. There are many factors that affect the growth and development of tobacco plants, the level of yield, the quality of the tobacco, and the rational selection of fertilizers and scientific fertilization in cultivation techniques are one of the main factors. In order to explore the relationship between high quality and high yield of flue-cured tobacco and fertilization, we conducted a pilot study on fertilization rate, fertilization time and fertilization method in 1978. First, the relationship between different fertilization levels and the quality of flue-cured tobacco The experiment was carried out in our hospital, the test area of a city acres, yellow soil, pH6.8-7.0, moderate fertility, the tested varieties Spring thunder, the density of 2,500 plants per acre, April 28 transplanting,
