不同砂质砂培漂浮育苗对烤烟烟苗及其产质量的影响
Effects of Different Kinds of Sand on the Sand-cultured Floating Seedling, Yield and Quality of Flue-cured Tobacco
摘要
Abstract
To select suitable nursery sandy substrate for tobacco float system, taking the conventional media mixed with vermiculite, humic Acid, peat as check, the experiment was conducted to study the influence of three different local sand materials which were mountain sand, Jinshajiang river sand, Rehe river sand on seedling of flue-cured tobacco by sand-cultured floating in Yongsheng County, Iijiang city. The results showed that the emergence rate and the seedling rate of Jinshajiang river sand and Rehe river sand were close to CK. The rate of sound seedling of sandy media was better than or close to CK, Rehe river sand was by 2% lower than CK, while Jinshajiang river Sand was higher by 1.7% than CK. The seedling root of Rehe river sand and Jinshajiang river sand grew well, the rates of root and shoot were coordination, the seedlings quality were well and gren well, while mountain sand were slightly inferior. All indexes of 3 treatments met the standard of sound seedling, and its costs decreased by 33.1 % than that of CK.关键词
