Abstract: The Chinese matrimony-vine is the Ningxia Guyuan original state area Qingshui river basin farmer＇s major economic income. In recent years along with the Chinese matrimony-vine price＇s unceasing rise,farmer＇s blind massive applied nitrogen, creates the nonessential waste.Through the Chinese matrimony-vine nitrogenous fertilizer employment quantity experiment, obtains the Chinese matrimony-vine in the coordinate employment phosphorus, in the potassium fertilizer situation,the nitrogenous fertilizer achieves when the ration increases production the effect to be best;This test result, north the original state area in the Sichuan water Chinese matrimony-vine production,in the soil medium fertility,the period of duration most little has four above times irrigates the condition the land parcel,667m2 executes nitrogen 45kg,when coordinate employment phosphorus 30kg,potassium 30kg the output reaches 375.0kg,（does not apply fertilizer） compared to the comparison increases production 50kg/667m2,increases production 15.3%. But 667m2 executes time nitrogen 60kg decline of production.Obviously,along with Shi Danliang increase,the Chinese matrimony-vine output has the ohvious production increase effect,when achieves 60 kilogram / 667m2,the output instead drops.
