First, the purpose of the test Through the calibration test to verify the accuracy of grape soil testing formula fertilizer and the best application of local formula fertilizer, contrast, test soil testing and fertilization effect, verify and optimize fertilizer formula. Second, materials and methods 1 for the crop 9-year-old grapes, varieties without nuclear white. 2. Test fertilizer urea (including N46%), three fertilizer (containing P2O544%), potassium sulfate (containing K2O50%). 3 experimental design set up three treatments, no duplication. Processing 1: blank area, an area of 50 m 2. Do not apply any fertilizer. Treatment 2: conventional fertilization area, an area of 300 m 2.667 m 2 base facilities goat 1500, urea 30 kg, 25 kg of diammonium phosphate; 667 m 2 topdressing urea 20 kg, 25 kg of diammonium phosphate.
