摘要
磷(P)是烟草生长的17种必需元素之一,由于烟草施磷过多,将导致烟叶粗糙,油润性变差,容易造碎,等级下降。根据都匀市多年烟叶生产施肥经验、2010年土样的分析结果及2012年配方肥试验结果,本着"稳氮、降磷、钾后移、调pH、适量补充中微量元素"的指导思想,在高磷烟区进行适量降磷试验,为烤烟合理施用磷肥提供依据。
Phosphorus （P） is one of the 17 kinds of essential elements of tobacco growth, the excessive tobacco P application, will lead to the tobacco turns crude, oily turns bad and it＇s easy to broken and it will degrade.According to DouYun city＇s years of experience of tobacco leaf fertilization production, the results of the analysis of 2010 soil samples and 2012 formula fertilization test results, in line with the guiding ideology ＂ to fix nitrogen, to dephosphorize, to make potassium backwards,to adjust pH, to add trace elements properly＂ the, made adequate- dephosphorization test in high phosphorus smoke region, it will provide basis for the retional application of phosphate.
