How to earth up ginger properly? Please give guidance
Earthing up is an important measure that determines ginger yield and quality. Only with proper earthing up can ginger grow vigorously and produce a high yield. The ginger rhizome needs to grow in a dark, moist environment and stops growing when exposed to light. Therefore, earthing up should be carried out as the ginger grows. If earthing up is not done in time, the ginger rhizome is exposed to the air, which seriously affects ginger quality and yield.
Ginger should be earthed up according to local conditions and timing; generally, 3 times of earthing up is appropriate.
The first earthing up begins when the ginger rhizome has 3-5 branches but has not yet emerged above the soil surface, with a soil thickness of about 2 cm. At this time, simply use small hoes or hooks and other farm tools to scrape the 4-5 cm wide ridge soil on both sides of the ginger planting furrow down along the ridge edge into the planting furrow, then water. This can both prevent weed growth and help the ginger rhizome expand. The first earthing up must not be too thick, otherwise it easily affects soil aeration, causing the growth of new ginger shoots to be hindered, reducing rhizome branching and slowing growth, affecting both yield and quality.
The second earthing up should be carried out 20 days after the first earthing up, with a soil thickness of 2-3 cm. At this time, the ridge soil on both sides of the ginger planting furrow can be leveled into the ginger planting furrow with small hoes or hooks and other farm tools. This earthing up also must not be too thick, otherwise it easily makes rhizome growth difficult and affects yield.
The third earthing up is also called "large earthing up" and is carried out 15 days after the second earthing up, with a thickness of 7-8 cm as appropriate. At this time, all the soil on the original ridges needs to be earthed up into the planting furrow, so that the original ginger-growing furrow becomes a ridge and the original ridge becomes a furrow. This earthing up is very important and is the key to determining the growth and development of the ginger rhizome. If the earthing up is shallow, the ginger pieces are short and thick; if the earthing up is thick, the ginger pieces are slender and long. Afterward, if any ginger shoots are found exposed, they should also be earthed up in time to ensure normal growth of the ginger rhizome.
Each earthing up should be combined with fertilization and watering; fertilizer should be applied first, then earthing up, then watering. Before the first and second earthing up, 5 kg of compound fertilizer and 40 kg of bio-organic fertilizer can be applied per mu, applied in a band about 15 cm from the plant base; compound fertilizer must not be applied at the plant base to avoid burning the seedlings, and after application, earth up and water. The last earthing up should increase the fertilization amount, as this is the period of fastest growth and development of the ginger rhizome, with a high fertilizer demand; 50 kg of compound fertilizer and 75 kg of bio-organic fertilizer can be applied per mu.
