涝害对烤烟产量和化学成分的影响研究
A Study on the Effect of Waterlogging on the Yield and Chemical Composition of Flue-Cured Tobacco
摘要
Abstract
In many flue-cured tobacco growth periods,soil moisture has the largest effect in the rosette stage,flourishing stage and budding stage.Too much or lack of water is the main inhibiting factor in yield and quality.Study on the water sensitivity in the three stages was of great significance in the field water manage-ment.Taking Yunyan 87 as the material,a pot test was carried out,the tobacco in the rosette stage,flourishing stage and budding stage was treated with different waterlogging levels,the waterlogging period were 24 h,48 h,72 h and 120 h.The results showed that:waterlogging had the greatest effect on yield in the rosette stage,water-logging for 120 h reduced production by 83%,but waterlogging in the rosette stage,and flourishing stage only lost 73%and 79%of production.Waterlogging had greatest impact on total nitrogen in the flourishing stage,wa-terlogging for 72 h,increased total nitrogen by 33%,but in the rosette stage and the budding stage,it only in-creased by 22%.Nicotine,reducing sugar,total potassium and total phosphorus contents were on the decline.In the flourishing stage the content of nicotine reduced by 87%.Yunyan87 is not resistant to waterlogging,3 d waterlogging,caused water stress,longer than 3d waterlogging caused growth block,even death to the plant.关键词
