T/LWB 005-2019 Laiwu Ginger Production Technical Specifications

Scope

Main technical content: 7.1 Before seedlings emerge after sowing, the focus is on heating and insulation. By raising the greenhouse temperature, the ground temperature can be rapidly increased, promoting rapid germination of ginger. During the day, the greenhouse temperature can be controlled at 40°C to 42°C. At night, tightly compress and compact the layers of plastic film to minimize heat loss and maintain a high temperature. After seedlings emerge and until the "three branching stages" (when the ginger aboveground stem increases from one to three or four), maintain a high temperature with daytime temperatures of 32°C to 35°C and nighttime temperatures of 25°C. From the "three branching stages" to harvest, maintain daytime temperatures of 28°C to 30°C and nighttime temperatures of 18°C to 20°C. 7.2 Watering: - Within one week after seedlings emerge, water them for the first time and apply a small amount of root-promoting fertilizer with the water. - Thereafter, water when the soil is dry and maintain soil moisture. In the early stage, water every 7 to 10 days; in the middle and late stages, water every 5 to 7 days.
