科学的 N·P·K 配比是主料烟生产的关键措施。目前,在中国生产出主料烟的地方还不多,尤其在主料烟施肥上有很多异议。怎样的 N·P·K 配方才能适合主料烟生产?诸城市烟草公司从1990年至1992年进行了主料烟科学配方施肥技术试验与开发,探索出了适合主料烟生产合理的 N·P·K 配方。实践证明,N·P·K1∶3∶4为最佳配方比例。由于此试验结果的推广,使诸城市主料烟生产达到了国内领先水平,主料烟出口量、出口价在全国独一无二。
Scientific NP-K ratio is the key measure of the main tobacco production. At present, there are not many places where main tobacco is produced in China. In particular, there are many objections to the main tobacco fertilization. What kind of NPK formula can be suitable for the main production of tobacco? Zhucheng Tobacco Company from 1990 to 1992 conducted a major experiment and development of science formula fertilizer technology, to explore the production of suitable for the main production of tobacco N · P · K formulation. Practice has proved that N · P · K1: 3: 4 for the best formula ratio. Due to the promotion of the test results, Zhucheng main cigarette production reached the leading domestic level, the main export of tobacco exports, the export price unique in the country.
