减施氮肥对烤烟叶片SPAD值、农艺性状和经济性状的影响
Effects of reduced nitrogen fertilizer application on leaf SPAD value,agronomic traits and economic traits of flue-cured tobacco
摘要
Abstract
Nitrogen is an essential nutrient for the growth and development of tobacco.The level of nitrogen supply in the soil plays a crucial role in the formation of tobacco yield and quality.In response to the problem that excessive nitrogen application in tobacco production may cause tobacco plants to be overgrown and late maturing,thereby affecting yield and quality,this article reviews the effects of reduced nitrogen fertilizer application on physiological characteristics,dry matter accumulation,agronomic traits and economic traits,in order to clarify the regulatory effect of nitrogen reduction on the growth and output of tobacco.Analysis showed that appropriate nitrogen reduction combined with the application of microbial agents,increased organic fertilizer application or biochar can all increase the SPAD value of tobacco leaves as well as root length,root surface area and root volume;reducing nitrogen fertilizer application by 20%or less,combined with corresponding agronomic measures,can promote the accumulation of dry matter in tobacco plants,enhance agronomic traits such as stem circumference,plant height,and the number of effective leaves,as well as increase yield,output value,and the proportion of top-grade tobacco.This article provides references for rational nitrogen reduction in flue-cured tobacco,optimization of cultivation management,and achieving high quality and efficient production.关键词
