| Through the research of edaphon of planting K326 on the condition of the interaction between the soil and climate, the results showed that in the entire growing period, bacteria account for the total number 68.38～78.05%, Actinomycosis 21.93～31.59%, Fungi just only 0.02～0.06%, Fungi has bigger difference in the number of three groups, Actinomycosis take second place, and the smallest is bacteria; Enzymes of the soil have different changes during the various periods of production and the same period of treatment. The number of microorganisms of cultivation in the big field (bacteria, actinomycetes, fungi) almost have no changes between before the transplant and after the regiment trees, bacteria have increased significantly until maturity, however the changes of soil microorganisms' number of potted plants are more earlier obviously. In the further of the relevant study, the number of bacteria and actinomycosis is positive correlation, the number of actinomycosis and fungi and the number of catalase and urease is positive correlation, above three groups of microorganisms showed negative correlation with urease.Soil bacteria of tobacco is influenced markedly by the soil and the climatic, the positive relativity between the number of bacteria and all phosphorus, all potassium, PH value, the exchange of calcium achieved significant level, an it showed negative relativity with effective iron, effective zinc. It showed positive relativity between bacteria and sunlight, radiation, temperature difference between day and night, vaporization in the regiment; It also showed positive relativity between bacteria and sunlight, radiation, temperature difference between day and night, vaporization in the mature period; It showed negative relativity with average cloudage and rainfall in the regiment and mature period, positive relativity with rainfall in the flourishing period. It is not difficult to find that the mian time that climate influences the number of bacteria is in the regiment period and mature period.The number of actinomycosis with no significant difference between climatic to soil conditions, Interaction between climate and soil conditions, relative to the other disposal, Liuyang climatic conditions Liuyang soil cultivation have great difference. Fungi in the role of various factors, no significant changes.Research on the two carotenoids decomposition and the general chemistry composition of tobacco, Damascenone and Megastigmatrienone, double sugar difference was highly significant positive correlation , with the chlorine significantly correlation, with the revert sugar,Alkaloids very significant negative correlation, with the total sugar was not obvious correlation, negative correlation with the TN. Megastigmatrienone and revert sugar is a very significant negative correlation, with chlorine very significant positive correlation, with the total sugar significant negative correlation, with the double-sugar difference significant positive correlation. Total sugar with the number of bacteria, actinomycetes, fungi and urease activity was negatively correlated, And have positive correlation with hydrogen activity, fungi and total sugar significant negative correlation. Reducing sugar and bacteria, actinomycetes have a positive correlation, and fungi, urease have a certain negative correlation role. Alkaloids and total nitrogen have a positive correlation bacteria with the number of bacteria, actinomycetes, fungi, which Alkaloids significant relationship with the bacteria, nitrogen and hydrogen peroxide activity of a negative correlation with the urease activity is related to,It can be seen through the soil microorganisms on Tobacco Control, flue-cured tobacco on the various indicators of the impact of appropriate, to achieve the objective of improving the quality of tobacco.
