施用稻壳生物炭对土壤养分及烤烟生长的影响
Affect of Rice Husk Biochar to Soil Nutrient and Tobacco Growth
摘要
Abstract
To explore the effects of rice husk biochar on soil properties and plant growth in tobacco field,a field experiment was conducted to investigate the physical and chemical properties of soil,agronomic traits and economic characters of to-bacco under gradient applied rice husk biochar in tobacco field.The results showed that:Gradient applied rice husk bio-char increased pH of acidic soil,Promoted soil organic carbon and total N accumulation gradually,Improved the releasing of alkaline hydrolysis N and available K.In addition,applied rice husk biochar promoted the number of productive tobacco leaves under different degree,the productive leaves number reached 18.0 /hill and 17.9 /hill under treatments of 9000 and 12000 kg/hm2 rice husk biochar respectively,which significant higher than CK.The ratio of first-class tobacco leaves reached 49.35% when 9000 kg/hm2 rice husk biochar applied,which is significantly higher than that of CK.关键词
