烤烟K326最佳施肥技术研究

The Optimum Fertilizing Technology for Tobacco K326

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/hm 2,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/hm 2,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.
