Ginger's high quality and high yield cultivation techniques
Plant two grooves measuring 180 centimeters in width and 10 centimeters in depth on the sampan. The bottom of the furrow should be covered with livestock and poultry manure. Apply 75 kilograms of cake fertilizer per 667 square meters, and use 15 to 20 kilograms of compound fertilizer as a base fertilizer. Afterward, cover the soil with a layer of 3 to 4 centimeters and wait for the next planting stage.
When determining the planting density, it is essential to consider multiple factors such as local farming experience, soil fertility, ginger size, and management level. Based on these elements, ginger planting density is typically categorized into three main types:
1. Low-fertility fields: When the ginger rhizomes weigh less than 50 grams, plant them 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 estimated yield of about 1,500 kg.
2. Medium-fertility fields: For rhizomes weighing between 50–75 grams, use a row spacing of 50 cm and a plant spacing of 16–17 cm. This leads to around 8,000 plants per 667 square meters, with a yield ranging from 1,500 to 2,250 kg.
3. High-fertility fields: If the ginger rhizomes are also 50–75 grams but the field has high fertility, plant them with a row spacing of 50 cm and a plant spacing of 19 cm. This allows for about 7,000 plants per 667 square meters, resulting in yields exceeding 2,250 kg.
If any of the conditions—such as soil fertility, rhizome size, or management level—do not meet the ideal standards, adjust the planting density accordingly by increasing or decreasing the number of plants.
There are several cultivation methods available. One common method is open-field cultivation, which includes flat planting, nest planting, and ridge planting. Another approach is using small arches, while the third is plastic film mulching. Mulching is highly recommended because it helps retain moisture, warms the soil, prevents nutrient loss, and improves soil structure. This promotes faster seedling emergence, stronger growth, and can increase yield by 30% to 50%.
When planting ginger, ensure that the buds face the same direction and that each row is straight. Place the buds upward so that the ginger is easier to harvest later. After planting, cover the seed fertilizer with soil, making sure the surface is slightly raised. Avoid leaving the fertilizer exposed for too long; if necessary, use regular soil as a substitute.
