烤烟K326最佳施肥技术研究

摘要

为了探讨长沙地区烤烟品种K326最佳施肥技术,2011年在浏阳进行了施氮量、基追肥比例、提苗肥种类和基肥施用方法对烟叶产质量影响试验.结果表明:施氮量165 kg/hm2处理烤烟的农艺性状,烟叶的中上等烟比例、产量产值都为最高 ;施氮量135 kg/hm2处理烤烟的农艺性状较好,各化学成分较为协调,均价最高 ;基追肥比例以基肥60％+追肥40％效果为最佳 ;提苗肥种类以磷酸二铵效果最好,施肥方式以穴施效果最好.%In order to find the optimum fertilizing technology for tobacco K326, the experiments were conducted in Liuyang in 2011 to study the effects of N fertilizer rate, ratio of basal fertilizer to topdressing fertilizer, types of topdressing fertilizer and applying methods of basal fertilizer on yield and quality of tobacco leaves. The results indicated that when N fertilizer rate was 165 kg/hm2, the agronomic characters, the ratio of middle-superior tobacco leaves, the yield and the output value of tobacco were the highest; when N fertilizer rate was 135 kg/hm2, the agronomic characters were good, the chemical components were harmony, and the average price was the highest; when the ratio of basal fertilizer to topdressing fertilizer was 60% basal fertilizer +40% topdressing fertilizer, the effect was the best; among the topdressing fertilizers, diammonium phosphate had the best effect, and the best fertilizer applying method was applying in the planting hole.
