烟地土壤结构改良剂的筛选与开发研究

Soil Conditioner Tobacco Screening and Development

天柱长期植烟、土壤机质含量锐减,土壤物理性状恶化、自然病害严重条件下,研究了运用熟石灰、PAM土壤结构改良剂进行处理对特色烟叶主要农艺性状和经济性状的影响。结果表明:混合施用熟石灰、PAM处理的土壤生产出的烟叶农艺性状表现最好,产量和产值最高,烟叶特色得到充分彰显。单施用熟石灰或PAM处理的烟株长势较好,经济性状次之。

Tobacco Tianzhu long, sharp drop in soil organic matter content, soil physical properties degradation, natural disease severe conditions, the study of the use of hydrated lime, PAM treated soil conditioner leaves on the main agronomic characteristics and economic traits. The results show that： Mixed use slaked lime, PAM treated soil to produce the best tobacco agronomic traits, the highest yield per hm： and the hm^2 yield, leaf characteristics fully demonstrated. Single application of lime or PAM treated tobacco crops are growing well, tollowed by economic traits.
