水溶肥配施对烤烟生长、养分吸收及品质的影响OA
Effects of water-soluble fertilizer application on the growth,nutrient absorption,and quality of flue-cured tobacco
为探究水溶肥配施对烤烟生长、养分吸收和品质的影响,设置5个水溶肥配施处理:H1,磷酸二氢钾 1.50 kg/667 m2、硝酸钾 3.90 kg/667 m2、硝酸铵钙 2.80 kg/667 m2;H2,硝酸钾 5.00 kg/667 m2、硝酸铵钙0.20 kg/667 m2、聚磷酸铵 1.40 kg/667 m2;H3,磷酸二氢钾 1.50 kg/667 m2、硝酸钾 3.90 kg/667 m2、尿素硝铵1.30 kg/667 m2;H4,硝酸钾5.00 kg/667 m2、聚磷酸铵1.40 kg/667 m2、尿素硝铵0.10 kg/667 m2;H5,磷酸二氢钾1.50 kg/667 m2、硝酸钾3.90 kg/667 m2、碳氮肥0.90 kg/667 m2,分析各处理烟株的生长发育特性、养分吸收及烤后烟叶化学成分.结果表明,农艺性状方面,团棵期,Ⅰ和Ⅲ烟区以H5处理对烟株生长促进效果最佳,Ⅱ烟区以H4处理表现较好;平顶期,3个烟区均以H5处理有利于烟株生长.干物质积累方面,Ⅰ和Ⅲ烟区在团棵期和平顶期均以H5处理积累最多;Ⅱ烟区团棵期以H5处理最高,平顶期根、茎干物质以H4处理最高.养分吸收方面,H5处理在Ⅰ和Ⅲ烟区各时期表现较佳,Ⅱ烟区团棵期以H4处理有利于叶部氮、磷、钾吸收,平顶期以H5处理有利于根、茎部氮、磷吸收.烤后烟化学成分分析显示,Ⅰ与Ⅲ烟区以H5处理最优,Ⅱ烟区以H4处理最优.综合来看,Ⅰ和Ⅲ烟区以H5处理为适宜的肥料配施方案;Ⅱ烟区可选择H4、H5动态调整施肥.
To investigate the effects of water-soluble fertilizer application on the growth,nutrient absorption,and quality of flue-cured tobacco,5 combined water-soluble fertilizer treatments were established:H1(1.50 kg/667 m2 of potassium dihydrogen phosphate,3.90 kg/667 m2 of potassium nitrate,and 2.80 kg/667 m2 of calcium ammonium nitrate);H2(5.00 kg/667 m2 of potassium nitrate,0.20 kg/667 m2 of calcium ammonium nitrate,and 1.40 kg/667 m2 of ammonium polyphosphate);H3(1.50 kg/667 m2 of potassium dihydrogen phosphate,3.90 kg/667 m2 of potassium nitrate,and 1.30 kg/667 m2 of urea ammonium nitrate);H4(5.00 kg/667 m2 of potassium nitrate,1.40 kg/667 m2 of ammonium polyphosphate,and 0.10 kg/667 m2 of urea ammonium nitrate);H5(1.50 kg/667 m2 of potassium dihydrogen phosphate,3.90 kg/667 m2 of potassium nitrate,and 0.90 kg/667 m2 of carbon-nitrogen fertilizer).The growth and development characteristics,nutrient uptake,and chemical composition of cured tobacco leaves were analyzed for each treatment.The results showed that,in terms of agronomic traits,at the rosette stage,the H5 treatment was found to be the most effective in promoting tobacco plant growth in the Ⅰ and Ⅲ tobacco-growing areas,while the H4 treatment performed better in the Ⅱ area.At the topping stage,the H5 treatment was found to be beneficial for tobacco plant growth in all three tobacco-growing areas.Regarding dry matter accumulation,the highest accumulation at both the rosette and topping stages was observed in the H5 treatment in the Ⅰ and Ⅲ areas.In the Ⅱ area,the H5 treatment was dominant at the rosette stage,whereas at the topping stage,the highest dry matter accumulation in roots and stems was observed in the H4 treatment.Concerning nutrient uptake,the H5 treatment was found to perform better at all stages in the Ⅰ and Ⅲ areas.In the Ⅱ area,the H4 treatment was found to be beneficial for nitrogen,phosphorus,and potassium uptake in leaves at the rosette stage,while the H5 treatment was found to be beneficial for nitrogen and phosphorus uptake in roots and stems at the topping stage.The analysis of the chemical composition of cured tobacco leaves showed that the H5 treatment was found to be optimal in the Ⅰ and Ⅲ areas,while the H4 treatment was found to be optimal in the Ⅱ area.Overall,the H5 treatment was considered a suitable fertilizer combination for the Ⅰ and Ⅲ areas,while dynamic adjustment of fertilization with H4 and H5 treatments was recommended for the Ⅱ area.
