摘要
为了提高肥料利用率和烟叶产量,改善烟叶品质,减少施肥量,减轻施肥对环境的影响,以云烟87为材料,于2014年在花垣县对萨派德肥料增效剂在烟草减量施肥中的应用效果进行了研究。结果表明,在施用萨派德肥料增效剂的同时减少0-10%的常规施肥量,可明显提高肥料的利用率,有利于烟草的生长发育,起到增产增收的效果;烟叶产量可增加153.0-208.5 kg/hm2,均价可提高0.7-0.9元/kg,中上等烟叶比例可提高2.1-4.8个百分点,产值可提高4 389.0-5 902.5元/hm2;而减少常规施肥量的20%则对烟叶的产量、品质及产值有较大的影响;这表明在施用萨派德肥料增效剂时,可酌情减少10%-20%的肥料量。
In order to increase fertilizer utilization rate, improve the quality of tobacco leaves, decrease the amount of fertilizer and reduce the environmental impact of fertilization, a test was conducted, taking Yuanyan 87 as the material, to analyze the effects of Sa＇s fertilizer synergist on the tobacco less fertilization at Huayuan in 2014. The results showed after the application of Sa＇s fertilizer synergist, the conventional fertilizing amount dropped by 0-10%, the use ratio of fertilizer was improved obviously. It was available to the growth of tobacco, and played a role in increasing productions. The yield of tobacco can increase 153.0-208.5 kg/hm2, leading to the average price can improve 0.7-0.9 yuan per kilogram. As regards to the quality of the flue-cured tobacco, there was a raise of the ratio of better than average by 2.1-4.8 percent, making increase of 4 389.0-5 902.5 yuan/hm2 in production value. The test also showed that 20% conventional fertilizing had significant influence on the yield, quality and value of tobacco. We can conclude that at the use of Sa＇s fertilizer synergist, the fertilizer amount can drop by 10%-20%.
