    摘要:

    通过田间小区试验研究了酸性土壤不同养分组合对生姜产量、品质及养分比例的影响。结果表明,N、P、K养分组合能使生姜显著或极显著增产(11.1%~79.4%),增产效果以高N(N2)组合大于低N(N1)组合,以配施Mo肥(N2P1K2Mo)组合增产最为显著。不同肥料组合使生姜粗蛋白、可溶性糖、淀粉含量分别增加1.3%~35.5%(N1P2K2、N2P1K1组合除外)、5.5%~92.7%(N2P2K3组合除外)和2.9%~36.7%(N2P2K3、N2P2K2Mo组合除外),降低粗纤维含量2.8%~11.9%(N2P2K2Mo组合除外),改善生姜品质。不同肥料组合降低生姜地上部全N、P、K含量和根茎全P、K含量,提高地下部全N含量。不同肥料组合提高生姜根茎N/P和N/K,降低K/P,而对生姜地上部N/P、N/K、K/P作用不一致。综合产量和品质效应,以N2P2K1处理最佳。

    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.
