不同降雨量条件下氮肥减施对云南烤烟产质量的影响
Effects of Reducing Nitrogen Application on Yield and Quality of Flue-cured Tobacco in Yunnan Province under Different Rainfall Conditions
摘要
Abstract
The aim was to study the effects of reducing nitrogen application amount on yield and quality of flue-cured tobacco in Yunnan Province under different rainfall conditions.The simulation test was carried out in artificial climate chamber using the tobacco cultivar K326 as test material to study the agronomic traits,photosynthetic characteristics,yield and quality under different rainfall and nitrogen reduction ratio.The results showed that with the appropriate reduction of nitrogen fertilizer,the agronomic traits,photosynthetic characteristics,yield and quality of flue-cured tobacco were improved obviously,and with the increase of rainfall,the determination indexes of flue-cured tobacco treated with the same nitrogen were basically increased firstly and then decreased.Respectively,the optimum nitrogen amounts in the areas with lower,moderate and higher rainfall were N_25％ (3.75 g per plant),N_35％ (3.25 g per plant) and N_25％ (3.75 g per plant),which could be popularized after field test.关键词
