Ginger in the planting time try to choose a flat swing, so that the operation and harvesting will be more convenient, the yield is also a lot higher than the vertical swing, if it is the north-south direction of the ditch, it is recommended that the ginger buds placed towards the west.
Ginger planting time
The planting time of ginger in the north and south is different, generally speaking, south can be planted in March-April, and if in the north, you need to wait until April-May to plant. The best time to plant ginger is in April-May each spring, when the environment is warmer and suitable for its growth and development.
How many seasons of ginger can be planted in a year
Ginger can be planted in one season a year. Because ginger is not hardy, it dies in cooler temperatures. But in a large greenhouse where the temperature is constant, you can grow ginger all year round.
Ginger Harvest Time
Ginger needs to be harvested around the winter solstice, mostly concentrated in the October-November period, which is the time when most ginger is harvested, and it is also very resistant to transportation at this time of year, in terms of its spicy flavor.
Ginger planting method
1, select the land
Select the soil layer is deep, water retention and fertilizer, fertile soil, good permeability, rich in organic matter sandy loam, loamy soil planting ginger. Ginger is not suitable for continuous cropping, nor should we choose tuberous root, fleshy root and tuberous crops as the previous crop, otherwise, serious pests and diseases, yield reduction and quality decline.
2, choose ginger
Buy ginger should be rough skin, darker color ginger, do not buy the sulfur smoked skin smooth, broken, bright color, irritating taste of ginger as seeds.
Long-term planting of ginger farmers in the harvest of ginger, choose to grow strong, disease-free, high-quality, high-yield plots to choose to stay fat, no pests and diseases, no rot, no injuries, buds full, head size uniformity, bright color, unfrozen ginger to do ginger seed storage.
3, germination method
Before sowing, according to the sowing time about 20 days in advance to start germination, you can use the greenhouse germination, germination in the kangang, cow dung germination, and other ways to germinate.
Keep ginger with a certain humidity, keep the temperature between 22-25 ℃, in order to cultivate into thick buds on schedule, the temperature is too high young buds thin and slender, the temperature is too low, germination is slow.
Ginger buds grow 0.5-1 cm, can be planted in batches. Ginger pieces broken by hand can also be cut with a knife, each ginger seed to retain 1-2 full buds, the wound can be coated with grass ash, conducive to wound recovery, if necessary, sterilized, to avoid rotting ginger seeds.
4, reasonable application of fertilizer
General selection of well-rotted chicken manure or goat manure as a bottom fertilizer, 1000-2000 kilograms per acre of land, and the soil is mixed evenly and then turned into the soil.
You can also apply 100 kilograms of cake fertilizer, 50 kilograms of compound fertilizer, or 25 kilograms each of urea, calcium superphosphate and potassium sulfate per acre, and apply them in the seeding furrow. Ginger is a chlorine-avoidant crop, and should not be applied to potassium chloride and other chlorine-containing fertilizers.
5, sowing
Pouring enough bottom water before sowing, water seepage after the ginger row. Ginger per mu density control in 5500 plants is appropriate, ginger plant spacing for 30 cm, row spacing for 40 cm, each hole put a ginger seed. Sprouting ginger can be placed upward seed buds, but it is best to choose a flat swing, both easy to operate and easy to harvest.
The east-west direction to open the furrow will be placed ginger buds towards the south, the north-south direction to open the furrow will be placed ginger buds towards the west. Mu with the amount of seed is generally 400-500 kilograms, the countryside has been ginger enough to say, so the seed ginger should be large rather than small. Mulch thickness of 4-5 cm,
6, field management
After the emergence of seedlings began to water, in the ginger seedling to 25 cm when the first fertilizer to nitrogen-based fertilizer. In the rapid growth of ginger tuberous roots for the second fertilizer to potash-based, with the application of three compound fertilizer, and then again after a month of potash and compound fertilizer, the number can be reduced by half.
7, pests and diseases
The pests and diseases of ginger mainly include ginger plague, spotted disease, leaf blight, eye spot disease, anthrax, ulcer, bacterial soft rot, ginger borer, ginger maggot, oblique night moth, etc. Summer is a high incidence of pests and diseases, early prevention, targeted prevention and control
8, Timely harvest
Ginger can be harvested maiden ginger, young ginger and old ginger, according to the need to choose. Stealing maiden ginger harvested in late June to early July. Harvest young ginger in September, you can pickle pickles.
Old ginger harvested around early November, if the temperature is lower than 10 ℃, ginger may be frozen, at the latest in the local first frost before the harvest. Stop watering 7-10 days before harvesting, otherwise the moisture content of the tubers will be too high and they will be prone to rotting during the storage period.
9, into the cellar storage
When the temperature drops to below 17 ℃ into the cellar storage, the temperature will be controlled between 12-15 ℃ later, the relative humidity is controlled at about 65%, to avoid the storage period of disease and rot. Do not put ginger in the refrigerator, otherwise it is extremely easy to rot and spoil.
