不同有机质含量土壤饼肥用量对烤烟产量及品质的影响

Effects of Different Cake Fertilizer Amount on Yield and Quality of Flue-cured Tobacco in Soil of Different Organic Matter Contents

通过云南省南华县3个有机质含量的土壤上饼肥用量试验,讨论饼肥在烤烟上的施肥效果。结果表明:施用饼肥的处理,上部叶的开片情况均好于对照;合理施用饼肥,可提高烟叶的产量和产值,但施用饼肥对上等烟比例的影响有所不同:在土壤有机质和速效氮含量较低的龙川红土门、徐营上庄试验点,施用饼肥处理的上等烟比例显著提高;在土壤有机质和速效氮含量较高的沙桥镇点,除施用饼肥50g/株处理的外,各处理的上等烟比例随饼肥施用量的增加而减少,且对照与施用饼肥90g/株间的差异达显著水平。

Through three dosage of cake fertilizer in soil of different organic matter content in Nanhua to explore the fertilization impact on flue--cured tobacco. The results showed that the treatment appling cake fertilizer, whose open piece of upper leaves were better than CK; Reasonable application of cake fertilizer can increase yield and benefits of tobacco, but effect of applying cake fertilizer on proportion of superior tobacco is different： the lower soil organic matter and available nitrogen content sites of Longchuanhongtumen and Xuyingshangzhuang, applying cake fertilizer treatment significantly increased proportion of superior tobacco; , besides applying cake fertilizer 50 g/plant, the proportion of superior tobacco decreased with the increase of applying cake fertilizer content, and the difference of CK and applying cake fertilizer 90 g/plant reached significant level in higher soil organic matter and greater available nitrogen content site of Shaqiao town.
