Effects Of Different Types Of Organic Fertilizer On Soil NPK Transformation And Flue-cured Tobacco Aroma Substances In Tobacco Planting Soil

This article researched the effects of combined application of chemical fertilizer and organic fertilizers like cow dung, fowl dung, biogas residue and straw on Soil NPK transformation and flue-cured tobacco aroma substances in tobacco planting soil under condition of equal nitrogen and 20% organic nitrogen through field experiment of sampling with mash bags. The results showed that :After different organic fertilizer with various forms of nitrogen and soil urease activity increased significantly, the organic fertilizer with each treatment is superior to the pure chemical fertilizers, including dry oil, chicken manure and chicken manure straw.Manure and straw mixed is advantageous to the decomposition of total phosphorus in soil mineralization, including chicken manure and cow dung treatment effect is superior to the renewal process, the change of available p in soil difference significantly between the groups, the existing within the scope of the data content of the soil phosphatase activity has not been antagonism between effective phosphorus content of soil effective phosphorus content there is room for further increase.After the fertilizer is applied into the soil, soil k content of each form has improved significantly, the clear difference between the contrasting chemical fertilizer and organic fertilizer processing, and the same between fertilizer and manure mixed with manure straw clear difference between processing.All the organic manure treatment compared with the pure fertilizer control increases the content of total nitrogen and potassium in flue-cured tobacco. In addition to outside the organic fertilizer processing have played an important role in reducing nicotine content in flue-curedtobacco, organic fertilizer processing sugar/nicotine ratio are in high quality tobacco leaf sugar/nicotine, nitrogen/nicotine ratio range, there is a significant difference between treatment.The processing of flue cured tobacco leaf in the total volatile aroma substance has a greater degree of improve, and the cow dung, cow dung, straw, straw and chicken manure and chicken manure, renewal, the renewal straw, straw, increase oil dry processing are respectively 407.62μg / g and 310.13μg / g, 304.90μg / g, 231.17μg / g,260.47μg / g, 241.62μg / g, 75.77μg / g and 345.32μg / g, and a single manure treatment were higher than the same kind organic fertilizer straw mixed processing. The organic fertilizer with obviously improved the carotenoids in flue-cured tobacco production and westpac alkanes degradation product content,including cow manure and cow dung, straw processing performance is better.After processing Organic manure plowing, soil nutrient have obvious differences between the nutrient supply of tobacco plant has had the obvious difference, time,quantity, persistence, eventually lead to different processing, flue-cured tobacco chemical composition, the aroma substance content, proportion has a significant effect.Cow muck, chicken manure, oil dry processing nutrient demand for fertilizer law suitable for flue-cured tobacco growth, having the excellent effect in the chemical component content, proportion and industrial table of smoking.
