One, choose the land. Choose deep soil, loose and fertile, convenient drainage and irrigation of sandy soil planting, avoid continuous cultivation.

Two, land preparation and base fertilizer. Before sowing mu 1000-1500 kg of farmyard manure, calcium magnesium phosphate fertilizer 50 kg, 20 kg of compound fertilizer for base fertilizer, after applying to fully ploughing and harrowing. The beds are furrowed, each bed is 1 meter wide, bed height 20 centimeters, and in the bed across the seeding ditch.

Three, seed ginger treatment and sowing. Before sowing the ginger seeds in the sun for 2 days, and then with 2% formalin seed disinfection 6-8 hours (pay attention to the disinfection should be washed with water), or with agro-streptomycin seed disinfection 6-7 hours. Sowing season for the beginning of March to mid-April, sowing specifications for the general plant spacing 0.25 m × 0.4 m, per mu sowing ginger 3500-4000 pieces.

Four, field management.

1, timely fertilization. Fertilizer in the seedling period to light, light fertilizer; later heavy fertilizer two times, the second is in early June to early July, this time is the Sun ginger peak period, is the peak of ginger absorption, acres of compound fertilizer 20 kg, 10 kg of urea; the second is in early September - early October, this time is the ginger tubers rapidly expanding period, acres of compound fertilizer 30 kg, 10 kg of potassium chloride.

2, appropriate shade cover. High summer temperatures, strong sunshine, ginger is extremely unfavorable in the summer, good shade cover is very necessary. Can be planted in the border between corn, soybeans and other crops or trellis shade. At the same time in the ginger rows covered with straw, reduce ground radiation, increase soil moisture.

3, water management. Ginger throughout the growth period must keep the soil moist, drought requires irrigation "running water", bed ditch stained water should be discharged in a timely manner.

V. Pest control.

(1) prevention and control of ginger plague: before sowing choose disease-free seed ginger, good seed ginger sterilization. Early onset of spraying agricultural streptomycin or leaf green double or Bordeaux liquid, every 15 days spray, *** spray 3-4 times. Heavy disease plants should be dug up and burned in time, and lime disinfection in the ginger hole.

(2) Prevention and control of anthracnose: use metribuzin + carbendazim to prevent and control the disease at the early stage of occurrence.

(3) Prevention and control of stem borer: use trichlorfon + carbofuran in the period of occurrence.
