Abstract
[Objective]In order to investigate the effects of biochar application on soil improvement and tobacco leaf development.[Method]Taking Yunyan 87 as test material,the biochar was set at 4 levels: CK (0),T1 (2 250 kg/hm2),T2(4 500 kg/hm2),T3 (6 750 kg/hm2).The effects of different rice straw biochar on soil nutrients and tobacco leaves were studied.[Result] Biochar increased the content of reducing sugar,total sugar and starch in the early stage,but decreased the content of the latter.The effects of biochar on nicotine and total nitrogen were light,and nicotine decreased.The chemical composition of tobacco leaves was more coordinated and the smoking quality was improved.The soil biochar could increase the content of organic matter,increase the pH value,increase the content of available potassium and reduce the content of available phosphorus.available nitrogen increased firstly and then decreased.The results of integrated soil nutrient and tobacco leaf quality were the best when application quantity of biochar was 4 500 kg/hm2.[Conclusion] The research can provide reference for situable application of biochar.关键词
