【Abstract】 The possibility was studied for taking the well drilling mud as additive of preparing the compounded & mixed fertilizer. Experimental method is: The harmful constituents were first eliminated, the every most suitable prescription was then selected by cross cut experiment, the optimal prescription was lastly evaluated and selected by method of score evaluating comprehensively. Optimal prescription is: urea∶ammonium phosphate∶potassium chloride=9∶8∶8, well drilling mud 32 g, Pztg Compounding additive 4g, water 3.5 g. The result indicates that the pressure resistant strength of the compounded & mixed fertilizer is 27.8 N under this condition, the total effective nutrient 31.6%, pH value 6.2, granularity rate 95.8%. Conclusion from experiment is: the granularity is comparatively better for taking the well drilling mud as the additive of fertilizer, it can be preliminary used for preparing of compounded and mixed fertilizer.更多还原
