Ginger cultivation should pay attention to timely planting
Open two grooves, each 180 centimeters wide and 10 centimeters deep, in the sampan. The bottom of the furrow should be covered with livestock and poultry manure. Apply 75 kg of cake fertilizer per 667 square meters, and use 15–20 kg of compound fertilizer as a base fertilizer. After that, cover the soil with 3–4 cm of topsoil and wait for the next planting stage.
Planting density must be carefully determined by considering various factors, including local farming experience and experimental results. Based on the fertility of the ginger field, the size of the ginger pieces, and the level of management, the planting density is typically divided into three categories:
1. Low-fertility fields: Use ginger pieces weighing less than 50 g, with a row spacing of 48–50 cm and a plant spacing of 14–15 cm. This results in approximately 9,000 plants per 667 square meters, with an expected yield of around 1,500 kg.
2. Medium-fertility fields: Use ginger pieces weighing 50–75 g, with a row spacing of 50 cm and a plant spacing of 16–17 cm. This leads to about 8,000 plants per 667 square meters, with a yield ranging from 1,500 to 2,250 kg.
3. High-fertility fields: Use ginger pieces weighing 50–75 g, with a row spacing of 50 cm and a plant spacing of 19 cm. This results in around 7,000 plants per 667 square meters, with a yield exceeding 2,250 kg.
If any of the above conditions are not met, the planting density should be adjusted accordingly to ensure optimal growth.
There are several cultivation methods available. The first is open-field cultivation, which includes flat planting, nest planting, and regular planting. The second is the use of small arches, and the third is plastic film mulching. It's recommended to use mulch, as it helps retain heat, protect nutrients, conserve moisture, and loosen the soil. This promotes faster seedling emergence, stronger growth, and can increase yields by 30% to 50%.
For proper ginger planting, make sure all the buds face the same direction and are aligned in straight rows. When placing the ginger, the buds should be facing upward, making it easier to harvest later. After planting, cover the seed fertilizer with soil, ensuring that the surface is slightly raised. Avoid leaving the fertilizer exposed for too long, and if needed, you can use regular soil instead.
