氮肥与土壤改良剂配施对烤烟生长及产量的影响
Effect of Nitrogen Fertilizer Combined with Soil Conditioner on Growth and Yield of Flue-cured Tobacco
摘要
Abstract
Effects of nitrogen fertilizer combined with soil conditioner on agronomic characters, leaf SPAD value,yield,output value and proportion of superior tobacco leaves were studied by field split-plot randomized block design experiment,so as to provide theoretical and technical basis for soil improvement and reasonable application of nitrogen fertilizer.Results showed that,plant height,stem girth,leaf number and leaf area of flue-cured tobacco increased with the increase of nitrogen application rate;the application of soil conditioner could increase plant height,stem girth,leaf number and leaf area of flue-cured tobacco.With the increase of nitrogen application rate,leaf SPAD values increased at vigorous growth stage,and first increased and then decreased at resettling stage and round top stage;the application of soil conditioner could decrease leaf SPAD values.With the increase of nitrogen application rate,tobacco leaf yield and output value increased,average price and proportion of superior tobacco leaves both first increased and then decreased with the peak value at nitrogen application rate of 45·0 kg/ha,67·5 kg/ha, respectively;the application of soil conditioner could increased yield and output value,but when the nitrogen application rate was greater than or equal to 67·5 kg/ha,the application of soil conditioner decreased the average price and proportion of superior tobacco leaves.Overall,the application of nitrogen fertilizer combined with soil conditioner could promote the growth of tabacco,and increase the yield of tobacco.关键词
