Abstract


In the condition of laboratory, four kinds of bacteria and four kinds of fungi has the ability of soluting phosphorus, design the experiment with Ca3（PO4）2 or leithin as the only P source,select four microorganism to do more researches by comparing the transparent circle. Dissolving the phosphorus circle with the salt water,take out which one is good for dissolubling abiophosphorous,which one is good for dissolubling phosphorous by using Determination of Molybdenum blue colorimetry. Do more research to know the ability of dissolubling phosphorous. The four microorganisms waere cultured in shaking flasks containing the media with Ca3（PO4）2 or leithin as the only P source for some time, determine the pH in cultural liquid、the concentration of dissoluble phosphorous、the concentration of dissoluble phosphorous which microorganism had absorbed、the weight of mycelium. analyzes its relevance. Get more information about the ability of dissolubling phosphorous by cultivating in soil. Product the mcrobial fertilizer by the four microorganisms,make feld tests with the organic fertilizer and the chemical fertilizer,as a example of eficient fertilizer. The results showed that:1. 10011 bacteria have a stronger ability of inorganic phosphorus, organic phosphorus capacity of 10,099 strong, fungi Ml, f2 for the solution of organic phosphorus and inorganic phosphorus have remarkable results.2. M1 was good for dissolubling phosphorous,there is no obvious effect of 10099 in soil text.3.In Different sources of phosphorus in liquid culture, the pH value of the liquid fermentation has droped in shanking;the best shanking time was for 84h, F2 neededo cultivate 108h, 10011 neededo cultivate 24h, 10099 neededo cultivate 36h. 4. Field tests showed that: the simple application of microbial fertilizer has better effect than only dealing with application of organic fertilizer on hight、yield、dry weight、sugar content and vitamin C;there was a good result by mixing microbial fertilizer and organic fertilizer; it’s best to increase in the proportion of fertilizer in mixed microbial fertilizer and organic fertilizer.
