When should ginger be planted? At what temperature will it be damaged by freezing?

The sowing date of ginger is when the local low temperature is stable 16 or above. Sowing can begin in March in the southern region, and planting or transplanting is usually carried out in May in areas with lower temperature. In order to prolong the growth time and increase the yield of ginger, the method of accelerating germination and sowing is generally adopted. The germination temperature of ginger is above 16. In the environment of 20 ~ 25℃, it germinates quickly, grows vigorously, and the temperature is too high, which has a great influence on the yield. In the process of accelerating germination, strong seedlings can be cultivated and planted within 15 ~ 20 days by controlling the temperature at 20 ~ 25℃. That is, germination should be accelerated/0/5 ~ 20 days before sowing. All localities can decide the suitable seeder according to 24 solar terms, and then push the time aside.

The germination temperature of ginger seeds is 16, and the suitable temperature for growth and development is 20 ~ 28. When ginger is planted in the open field, the average temperature starts from above 12. Don't do it too early. Otherwise, it will be vulnerable to night frost and ginger will freeze. The author planted ginger in the open field in late March, that is, after the vernal equinox of the lunar calendar. If it is covered with plastic film, it can be planted about 10 days in advance.

Avoid eating ginger in the New Year. Otherwise, it is easy to get sick and the yield is not high. Generally speaking, it is best to choose plots where ginger has not been planted for more than 5 years. It is best to plant rice and stumps alternately in flood and drought. Ginger likes to grow in an environment where the sun is 7 points and the sun is 3 points. In addition to Pingba, when planting ginger in mountainous or hilly areas, suitable land should be selected to meet the demand of ginger growth and development for environmental conditions.

Before planting ginger, split the ginger, and each piece of ginger can retain 2 ~ 3 complete buds, weighing 50 ~ 100g. You can plant it yourself or germinate it yourself. But whether it is planted directly or germinated, ginger should be disinfected. Disinfection of ginger: choose one of agricultural streptomycin, zinc ginseng, methicillin and other fungicides. , mix well in a basin, soak ginger in the liquid medicine, take it out after 10 ~ 15 minutes, and plant it directly or after germination. Build a plastic film greenhouse with bamboo and wood in the sun. Put ginger seeds on wet soil, cover them with wet sand, and cover them with washers, grass or old sacks of cows and sows to keep warm and moist.

After grinding the land with a sonar machine, level it with a rake to make tungsten 2-3 meters wide. Planting ditches horizontally in the field, with a distance of 50-70 cm and a depth of 25-30 cm. Open ditches are drained around, and open ditches are drained in the middle according to the situation.

Planting ditches and digging holes at the edge of rice fields, with a blood distance of 25 cm. Put a slice of ginger in each blood, cover the ginger seeds with soil slightly, sprinkle with compound fertilizer and organic fertilizer, and then cover the fertilizer with soil strictly. Generally, 40-50kg of compound fertilizer and 0/000-/0/500kg of organic fertilizer can be applied per mu. In order to keep warm and moist, it can be covered with crop straw or plastic film. Although covered by crop straw, it still remains under ginger plants, and the rotting is organic fertilizer. Cover with plastic film, and peel ginger when harvesting.
