Effect of Transplanting Tobacco Seedlings under Plastic Film on Tobacco Growth and Production and Quality
摘要
Abstract
[Objective] To study the effect of transplanting tobacco seedlings under plastic film on tobacco growth and production and quality.[Method] A comparative experiment of transplanting seedling and conventional transplanting under different transplanting period was carried out,the growth and development of tobacco plants and their quality indexes were analyzed.[Result] The survival rate of the tobacco plant was increased by the small seedling transplanting on April 25.The anti-effect of the mosaic disease increased by 60.95％,and the prevention of the black tibia increased by 51.61％.The field growth and disease resistance were enhanced,the growth period of the field was shortened and the final harvest was advanced,it can effectively avoid the low temperature and rain in the late fields.Submembrane seedling transplanting method can reduce the content of nicotinic and chloride ion,increase the potassium content of tobacco leaf,it was conducive to the improvement of the coordination and intrinsic quality of the chemical composition of tobacco leaf.In terms of yield and quality,the average price and output value of the tobacco on April 25 was the highest,economic traits showed obvious advantages,the survival rate of T1 transplanting was reduced,the economic traits were slightly lower than CK.It was suggested that seedling transplanting may be beneficial to the early stage of growth,it can avoid the effects of early drought and later cold,but not the sooner the better.[Conclusion] It was appropriate to transplant the seedlings on April 25.关键词
