不同栽培模式下生姜品质及经济效益的比较研究

Comparative Study on the Quality and Economic Benefit of Ginger Under Different Cultivated Patterns

以四川地方品种犍为黄口姜为试材,研究比较了不同栽培模式对生姜内在品质及经济效益的影响。结果表明:生姜与大豆间作(处理1)和生姜与四季葱间作(处理2)能有效提高生姜块茎中维生素C含量,分别较单作生姜显著提高了3.29%和4.05%、处理2显著提高了可溶性糖8.24%、姜辣素4.51%和蛋白质等有益物质的含量,降低了硝酸盐有害物质的含量,其中处理1显著降低了14.00%,改善了姜块的外观和内在品质。并且,生姜与大豆间作的纯收入和产投比最高,分别较生姜单作提高了24.80%和8.80%。

Taking ＇Jianweihuangkou＇ ginger of Sichuan local variety as material,internal quality and economic benefit of ginger at different cultivated patterns were studied in this article. The results showed that intercropping with ginger and soybean（Treatment 1）and intercropping with ginger and four seasons Onions（Treatment 2） effectively increased Vitamin C content,increased 3.29 % and 4. 05% compared to solo ginger. Treatment 2 significantly increased contents of beneficial substances such as soluble sugar with 8. 24%, gingerols with 4. 51% and protein. Treatment 1 significantly decreased contents of deleterious substance namely nitrate with 14. 0% and improved appearance and internal quality of ginger rhizome. Furthermore,treatment 1 could obtain better economic benefit and showed the highest net income and ratio of benefit and cost whose values respectively increased by 24. 80% and 8. 80% compared to solo ginger.
