Abstract

Abstract:

To promote the development of the ginger industry in Cixi City and improve the agricultural industrial structure, this study explored the appropriate planting density for three ginger varieties with favorable comprehensive traits, which were selected from preliminary variety screening trials. Under fixed row spacing, three plant spacing levels (15, 20, and 25 cm) were set to compare the growth and yield of ginger at different growth stages. The results showed that planting density had little effect on plant growth during the tillering stage, but obvious differences were observed during the rhizome expansion and harvest stages. As planting density decreased (plant spacing increased), the number of branches, fresh root weight, and fresh rhizome weight increased, reaching their maximum at a plant spacing of 25 cm. The yields of Lishui Xiaohuang ginger and Jiaxing Hongzhao ginger were highest at a plant spacing of 15 cm, with 667 m² yields of 1 856.52 and 1 983.41 kg, respectively. Laiwu litter ginger achieved its highest yield at a plant spacing of 20 cm, with a 667 m² yield of 2 364.87 kg. Planting density significantly affected the dry matter content of Jiaxing Hongzhao ginger and the dry matter and starch content of Laiwu litter ginger. In conclusion, it is recommended to plant Lishui Xiaohuang ginger and Jiaxing Hongzhao ginger at a plant spacing of 15 cm, and Laiwu litter ginger at a plant spacing of 20 cm for optimal production.

Key words: ginger, planting density, yield, nutritional quality
