一、模式 多年实践表明,该区烤烟生产应以优质填充料为主。一般亩栽1300～1500株烟苗,每株留叶18～22片,亩产150～200公斤。根据这一目标,每亩需供给4.5～6公斤纯氮。 二、技术要点 1.亩产超300公斤小麦、500公斤玉米及其他碱解氮大于60毫克/公斤的田块不宜种烟。 First, the model Years of practice shows that the production of flue-cured tobacco should be based mainly on high-quality filler. The general planted planted 1300 ~ 1500 tobacco seedlings, leaving 18 leaves per plant leaves 22, per mu 150 to 200 kg. According to this goal, per mu need to supply 4.5 to 6 kg of pure nitrogen. Second, the technical points 1. Mu per kilogram of wheat over 300 kilograms, 500 kilograms of corn and other alkaline hydrolysis of nitrogen more than 60 mg / kg of plots should not be planted with tobacco.
