14年生金冠苹果,喷布光合多元微肥,能显著提高果实品质。喷布次数与单果重、可溶性固形物含量和果肉硬度呈正相关,处理间差异分别为F=0.76(F0.05=2.87,F0.01=4.43)不显著、F=4.25显著和F=10.43极显著。经L·S·D多重比较,与对照相比,喷布微肥3次可溶性固形物含量差异(差异值1.7
14-year-old Golden Delicious apple, spray photosynthetic multivariate fertilizer, can significantly improve fruit quality. The number of spraying was positively correlated with fruit weight, soluble solids content and fruit firmness. The differences among treatments were F = 0.76 (F0.05 = 2.87, F0.01 = 4.43), F = 4.25 significantly and F = 10.43 Significant. Compared with the control by SL · D multiple comparisons, the content of soluble solids in three times of spraying micronutrients (difference 1.7
