Abstract:Field experiment was conducted to study the effect of different fertilization on the yield, quality, nutrient content and ratio of ginger in acidic soil. Results indicated that the yield of ginger increased significantly by 11.1%~79.4% in all treatments, and the effect was better in applying high level nitrogen fertilizer treatments than in low level nitrogen fertilizer treatments. The yield of ginger was highest in N2P2K2Mo treatment. The contents of crude protein, soluble sugar and starch increased by 1.3%~35.5% (except N1P2K2 and N1P1K1 treatments), 5.5%~92.7% (except N2P2K3 treatment) and 2.9%~36.7% (except N2P2K3 and N2P2K2Mo treatments) respectively in all treatments, and the content of fibrin decreased by 2.9%~11.9% (except N2P2K2Mo treatment), which was better to the quality of ginger. Different fertilizer combinations could reduce the content of total N, P, K in the above-ground of ginger and the content of total P, K in rhizome, increase the content of total N in rhizome. The ratios of N/P and N/K increased and the ratio of K/P decreased in rhizome of ginger. There were different effect of different fertilization on the ratios of N/P, N/K and K/P in the above-ground of ginger. N2P2K1 treatment was the best combination for higher yield and good quality of ginger.
