科学施肥,促进土壤氮、磷、钾比例协调,是获得烟叶优质丰产的重要条件。为了探索烟叶优质丰产与施肥的关系,我们自79年开始,在我县张村公社冠军大队、城郊公社湍南大队,稂东公社新铺大队进行了烟叶施肥试验研究。通过三年来的试验,在烟叶科学施肥方面取得了初步的成果,并已在生产中发挥了作用。 Scientific fertilization and soil nitrogen, phosphorus and potassium to promote the coordination of the ratio is to obtain high yield and quality of tobacco is an important condition. In order to explore the relationship between high-yield and high-yield tobacco and fertilization, since the beginning of the year 79, we conducted a pilot study on tobacco leaf fertilization in the champion brigade of Zhangcun commune in our county, the Turon-south brigade in the suburbs commune, and the new pavement brigade in Cheongdong commune. After three years of experiments, preliminary results have been achieved in scientific tobacco leaf fertilization and have played a role in production.
