1, land selection. Choose deep soil, water retention and fertilizer, fertile soil, good permeability, organic matter-rich sandy loam, loamy soil planting ginger. Ginger is not suitable for continuous cropping, and should not choose tuberous roots, fleshy roots and tuberous crops as the previous crop, otherwise serious pests and diseases, yield reduction, quality decline.
2, choose ginger. Purchased ginger should be rough skin, darker color ginger, do not buy was 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 selected to stay fat, disease-free, no insects, no rot, no injuries, buds full, head size uniformity, bright color, unfrozen ginger pieces to do ginger seed storage.
3, choose the seeding time. Ginger germination temperature is high, the sowing period is generally 3-5 months, North and South varies greatly to the local soil temperature above 16 ℃ for sowing, not too early or too late.
4, germination method. Before sowing, according to the sowing time about 20 days in advance to start germination, you can use the greenhouse germination, kang germination, cow dung germination and other ways to germinate, keep ginger has a certain degree of humidity, keep the temperature between 22-25 ℃, in order to be able to cultivate into a thick buds on schedule, the temperature is too high young buds are 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 retains 1-2 full buds, the wound can be coated with grass ash, which is conducive to wound recovery, and sterilized if necessary, to avoid rotting ginger seeds.
5, reasonable application of bottom fertilizer. Generally choose to use rotted chicken manure or sheep manure as a bottom fertilizer, 1000-2000 kg per acre of land, and soil mixing evenly after turning into the soil, you can also apply 100 kg of cake fertilizer per acre, ternary compound fertilizer 50 kg, or urea, calcium superphosphate and potassium sulphate 25 kg, in the sowing ditch into. Ginger is a chlorine-avoidant crop, and should not be applied to potassium chloride and other chlorine-containing fertilizers.
6, sowing. Sowing before watering the bottom of the water, water seepage after the row of ginger. Ginger per mu density control in 5500 plants is appropriate, ginger spacing for 30 cm, row spacing for 40 cm, each hole put a ginger seed. Germinating ginger can be placed upward seed buds, but it is best to choose a flat swing, both easy to operate and easy to harvest. For east-west furrowing place the ginger buds towards the south, and for north-south furrowing place the buds towards the west. Mu with the amount of seed is generally 400-500 kilograms, the rural areas have ginger enough to say, so the seed ginger should not be small.
