摘要
[目的]研究不同浓度磷酸二铵对烟叶生长的影响.[方法]以云烟87为材料,研究不同浓度磷酸二铵对烟株农艺性状、烟叶物理指标、外观质量、化学成分和经济性状的影响.[结果]移栽后10 d用5 g/L磷酸二铵灌根(每隔10 d 1次,共3次),烟叶产质量均较差;移栽后10 d用10 g/L磷酸二铵灌根(每隔10 d 1次,共3次),烟叶产质量较好,优于对照;移栽后10 d用15 g/L磷酸二铵灌根(每隔10 d 1次,共3次),烟叶产量较高,但质量较差.[结论]移栽后10 d用磷酸二铵灌根(10 g/L,每隔10 d 1次,共3次)效果较好,可以进一步进行示范推广.
Abstract
[Objective]To study the effect of different concentrations of DAP on tobacco growth.[Method]Took Yunyan 87 as materials,effects of different concentrations of DAP on tobacco agronomic traits,physical indexes,appearance qualities,main chemical components,economic traits were studied.[Result]The yield and quality of tobacco were inferior by using 5 g/L DAP at 10 days after transplanting(once every 10 days,three times).The yield and quality of tobacco were better by using 10 g/L DAP at 10 days after transplanting(once every 10 days,three times),which was superior to control.The yield of tobacco was higher by using 15 g/L DAP at 10 days after transplanting(once every 10 days,three times),which the quality was poor.[Conclusion]The effect of using 10 g/L DAP at 10 days after transplanting(once every 10 days,three times)is better,which can be further demonstrated.
