Ginger planting technology and management

1, land preparation: choose deep soil, loose soil, good drainage and permeability, fertile soil rich in organic matter of the land, per acre of land to apply 3,000 kg of rotted organic fertilizer and 30 kg of potassium sulfate; deep plowing and deep turning, the fertilizer turned into the soil, and then digging a ditch, ditch distance of 50-55cm, ditch width of 25 cm, the ditch depth of 10-12cm.

2, ginger seed treatment: choose ginger fat, bright color, not dry shrinkage, no pests and diseases of ginger as ginger seed, and then placed in the temperature of 22-25 ℃, humidity of 60-80% of the environment for germination; catalytic good buds, the ginger seed broken into small pieces of 75-100g, each piece of ginger need to ensure that there is a young shoots.

3, sowing: when the 10cm ground temperature stabilized to 16 ℃ or more, choose a sunny weather sowing, sowing before the application of sufficient bottom water, sowing covered with a layer of 4-5cm after the soil. Sowing method: put the seed block horizontally in the ditch, so that the direction of the young shoots to keep the same, the distance between each ginger seed is 18-22cm.

4, fertilization: seedling fertilizer, per acre of water with the imposition of 1,000kg of human manure or 10kg of urea; before and after the autumn, per acre of land with the imposition of 1,000kg of rotting organic fertilizer, 15-20kg of ternary composite fertilizer; the beginning of September, per acre of land with the imposition of 30kg of compound fertilizer. 30kg of three yuan compound fertilizer per mu.

5, moisture: summer in the morning and evening watering once to reduce the low temperature; after the fall, ginger for the high degree of water demand, need to ensure that the relative humidity of the soil in the 75-80%; 3 days before the harvest to pour the last water.

6, artificial management: mainly to prevent and control ginger plague. Before sowing, use 72% agricultural streptomycin soluble powder 4000 times solution to soak the seed for about 48 hours; when the disease occurs, use 72% agricultural streptomycin soluble powder 4000 times solution to irrigate the root, 250 ml per plant, every 10-15 days of application, a **** application 3-4 times.

Two, an acre of land needed ginger seeds

1, the need for ginger seeds

If the soil is fertile high-yield field, generally an acre of land using about 700-800 pounds of ginger seeds; if it is the soil fertility of the average field, generally an acre of land using 400-500 pounds of ginger seeds.

2, sowing density

(1) If it is a high-fertility field, plant about 5000 plants per acre, with row spacing of 60-70cm and plant spacing of 20-25cm; if it is a medium-fertility field, plant about 6000 plants per acre, with row spacing of 60cm and plant spacing of 20cm; if it is a low-fertility field, plant about 7000 plants per acre, with row spacing of 50-55cm and plant spacing of 18-25cm. 55cm, plant spacing is 18-20cm.

(2) If medium-fertile field planting large ginger, plant 5500-6000 plants per mu, row spacing is 60-65cm, plant spacing is 20cm; if planting small ginger, plant 7000-7500 plants per mu, row spacing is 50-55cm, plant spacing is 18-20cm.
