摘要
本文通过烤烟盖膜对比试验,确定了揭膜最佳时期:白膜5月中旬、蓝膜5月下旬.分析了烤烟不同处理的温湿效应与优质适产关系.烤烟盖膜后优质适产效果显著:盖蓝膜和盖白膜的平均产量分别为:140.05公斤和147.45公斤.比对照分别增产10%和14%,烟碱含量适中,盖蓝膜和盖白膜分别为2.188%~2.341%和2.508%~2.983%之间.根据产质分析,均达优质适产批标.
This paper deals with the optimum time to remove the plastic sheeting from tobaccoplants through contrast experiments on tobacco under sheeting;the last ten days of May forblue-coloured sheeting and the second ten days of May for white-coloured sheeting.The re-lation between the temperature-humidity effects of different treatments and adequate yieldwith high quality is analysed.The effectiveness of sheeting tobacco plants is remarkable foradequate yield and high quality.The yields of tobacco covered with blue and whites sheetingsare 2(?).1 jin/mu and 294.9 jin/mu respectively,increasing by 10% and 14% over that ofunsheeted tobacco.The nicotine contents in tobacco are moderate:2.188%~2.341% in thatcovered with blue sheeting and 2.508%~2.983% in that covercd With white sheeting.According to analysis,both the yield and quality are up to the standards.
