The planting method and time of alpinia officinalis in Guangdong are mostly planted at the end of March and the first ten days of April.

Select ginger species: choose ginger species with uniform growth, moderate size and intact epidermis. Select land: select newly reclaimed land with high topography and loose soil. Planting season: generally from the end of March to the middle of April. Management: Shajiang is not cold-resistant and afraid of waterlogging, so special attention should be paid to drainage and timely and reasonable fertilization. Pest control: sand ginger is prone to diseases, after the emergence of diseases and insect pests need to be controlled in time.

First, select ginger species

The main results are as follows: 1. When planting sand ginger, we should first select the ginger species, and try to choose the healthy ginger species with uniform growth, fresh meat color, moderate size, mature, disease-free and intact epidermis.

2. If there are signs of decay, discoloration of soft branches and exfoliation of the epidermis, they must not be used as ginger.

3. After selecting the ginger seed, it should be disinfected before it can be planted.

II. Selection of land

1. Sand ginger is suitable for planting in sandy soil with high topography, loose soil, good drainage and irrigation, high fertilizer, and preferably new reclaimed land.

2. The land that has been planted with ginger in recent years should be avoided as much as possible, because growing ripe land will easily lead to ginger disease.

3. When planting, the soil should also be disinfected. Generally, 0.5 kg of 50% Dysenamine and 50% carbendazim powder will be used for disinfection, then about 400 kg of water will be mixed with water, and the soil will be evenly sprayed 2-3 days before planting. After spraying, the land needs to be ploughed evenly.

3. Select planting season

The main results are as follows: 1. The planting season of sand ginger is very strong, which is generally planted from the end of March to the middle of April. It needs to be dried before planting, and the ginger after drying can promote germination.

2, before planting, need meticulous soil preparation, open a good drainage ditch, apply basic fertilizer, and then plant the ginger, the plant distance is about 15 cm, and you can plant about 200 kg of ginger per mu.

3, after planting, to cover with fine fertile soil, encounter the dry season, need to water in time, if the field allows, you can also cover with grass to keep warm and moisturizing, so that seedlings can emerge more quickly.

IV. Management

1. In the process of planting sand ginger, we must do a good job of drainage and irrigation, drench water in time when dry, pay attention to drainage during the rainy season, and strictly prevent stagnant water in ginger fields.

2. When raising seedlings, if the soil in the ginger field is hardened, it is necessary to loosen the soil in time, so that the seedlings can emerge better and faster.

3. If you want to replenish the seedlings, some fertilizers should be added when replenishing the seedlings to ensure the consistent growth of the whole seedlings.

4. The fertilizer in ginger field is mainly organic fertilizer, and the base fertilizer is mainly rotten organic fertilizer, which needs more than 2000 kg per mu. The fertilizer efficiency of organic fertilizer is long, which can ensure the growth of ginger.

5. Topdressing is generally chosen during weeding and the peak growing season, and human and animal manure can be applied when topdressing, and the suitable compound fertilizer can be selected according to its growth.

V. Disease and pest control

1. Sand ginger is very prone to diseases, generally more for fungal diseases, if found to spray immediately to prevent and spread.

2. If there are rotten leaves, rotten roots and rotten ginger, Bordeaux liquid or other fungicides can be used to spray and control.
