摘要
在云南省种烟的12个地州采集土样683个和烟叶样品进行分析化验,结果表明,云南土壤pH值总体上都在适宜范围,唯有思茅地区的pH值偏低;有机质和有效氮含量偏高;有效磷含量除了昆明和玉溪的偏高外,其它地区的在适宜或缺乏范围;尽管土壤中有效钾含量较高,但烟叶中钾含量仍然偏低,为此生产上提出了“控氮和补钾”的施肥措施,特别是土壤养分相对较贫乏的新烟区如思茅在生产上需适量增加施肥量并注意各种肥料的合理搭配。
Soil and tobacco leaf samples were taken in 12 regions of Yunnan province. The results showed that most soil pH was in appropriate amount for tobacco, onlyit was low in Simao area . The high content of soil organic matter and available nitrogen was found. Soil available P ranged from appropriate to deficiency for most regions except for Kunming and Yuxi regions. It wao faund that soil available K was rich but the content K in leaf was low. So the tobacco fertilizer strategy in Yunnan province should be controlling nitrogen and supplying potassium. For low nutrients area such as Simao area more and rational ratio fertilizer application was recommended.
