Influence Of Different Proportion Of Cake Fertilizer And Chemical Fertilizer On The Yield And Quality Of Yanbian Flue-cured Tobacco

This experiment adopts Jiyan 9 to conduct different ratio of cake fertilizer and chemical fertilizer, and analyzes agronomic characters of different treated tobacco plant, all kinds of main chemical components in tobacco leaf and economic characters, etc.The experiment results show that the growth of treated tobacco plant with cake fertilizer is worse than that with chemical fertilizer in the earlier stage, but in the middle and later periods of growth, the tobacco plant height, stem girth, maximum leaf length, maximum leaf width, etc, are obviously increased. The comprehensive test results show that 60% chemical fertilizer-40% soybean cake fertilizer,80% chemical fertilizer-20% soybean cake fertilizer,60% chemical fertilizer-40% soybean cake fertilizer have the optimum performance.The potassium, chlorine, total sugar, reducing sugar, total nitrogen, nicotine of treated tobacco plant in the upper leaves, middle leaves and lower leaves are higher than that with chemical fertilizer, and the potassium-chlorine ratio and nitrogen-nicotine ratio are also higher than that with chemical fertilizer, but the starch and protein content of flue-cured tobacco with cake fertilizer treatment is lower than that with chemical fertilizer treatment. So using cake fertilizer has promoting effect on the chemical quality of flue-cured tobacco. It can be found through the comprehensive evaluation of influence of different cake fertilizer on flue-cured tobacco’s upper leaves, middle leaves and lower leaves that 60% chemical fertilizer-40% soybean cake fertilizer,80% chemical fertilizer-20% soybean cake fertilizer,60% chemical fertilizer-40% sesame cake fertilizer have the optimum performance.The total output, first-class tobacco proportion, upper-middle tobacco proportion, average price and total output value, etc of treated tobacco plants with cake fertilizer treatment is superior to that with chemical fertilizer treatment. It can be seen that the cake fertilizer treatment can significantly improve the economic characters of tobacco leaves. It can be found from the overall consideration of economic characters that 60% chemical fertilizer-40% peanut cake fertilizer,80% chemical fertilizer-20% soybean cake fertilizer,60% chemical fertilizer-40% sesame cake fertilizer have the optimum performance.Through the comprehensive analysis of the agronomic characters of treated plants, chemical quality and economic characters of roasted tobacco leaves, it can be found that 80% chemical fertilizer-20% soybean cake fertilizer,60% chemical fertilizer-40% sesame cake fertilizer are the most reasonable proportion of fertilizers in order to improve the yield and quality of flue-cured tobacco.
