Planting method of ginger

L, strictly choose land to avoid continuous cropping: choose sandy loam, loam and clay loam with fertile soil, deep soil layer, good air permeability and rich organic matter, and require the land to be slightly higher in terrain, convenient for irrigation and drainage and not easy to accumulate water. Ginger is not suitable for continuous cropping, but should be rotated with rice, cruciferous and leguminous crops for 3-4 years.

2. Selection of ginger seeds to promote early growth: Choose old ginger with full ginger pieces, bright color, fresh and tender meat, hard texture, 1-2 strong buds, weight of 50-75g and no disease as the planting ginger. Soak ginger in 500 times solution of 50% carbendazim for disinfection before sowing. After disinfection, ginger should be aired for 2-3 days. When the surface of ginger is shiny, it can be piled up and covered with straw to keep warm and germinate. It is required to keep wet and control the temperature at 20-25℃. When the ginger buds grow to 1cm, they can be planted.

3, timely sowing, reasonable close planting: good irrigation conditions, high temperature, no germination, sowing in the shocking season; Without irrigation conditions and low temperature, it is necessary to accelerate germination, and sow in Tomb-Sweeping Day or Grain Rain season. The sowing row spacing is 35-40 cm, the plant spacing is 26-30 cm, the ditch depth is 10-20 cm, and the seeds used per mu are about 500 kg. Use/kloc-0.5 kg urea and 25 kg compound fertilizer as seed fertilizer per mu, and put the fertilizer into the ditch and mix it evenly with the soil. Before sowing, pour the bottom water about 1 hour to make the soil moist. Put the ginger slices horizontally in the ditch, keep the buds in the same direction, gently press them into the mud with your hands, and cover them with fine soil about 5 cm.

4. Apply base fertilizer and topdressing scientifically: Ginger has a long growth period, so the principle of applying base fertilizer and topdressing for many times should be adopted. When preparing soil, 3000 kilograms of decomposed organic fertilizer and 25 kilograms of potassium fertilizer are used as base fertilizer per mu. When the seedling height is about 30 cm and there are 1-2 branches, topdressing 1 time, applying 20 kg of urea per mu, or watering the seedlings with clear manure water; Before and after beginning of autumn, 50 kilograms of compound fertilizer and 25 kilograms of potassium sulfate were applied to each mu, which were applied in the ditch about 15 cm away from the plant base and covered with soil for irrigation; When the underground rhizome swells, apply urea 10- 15 kg and potassium sulfate 15-20 kg per mu.

5. Shading and cooling to promote growth: Ginger is a shade-loving plant, which is not resistant to high temperature and strong light. When growing in summer, it should be shaded to promote growth. There are many ways to shade, such as building a shed to shade, or intercropping with corn, a tall crop.

6. Prevent drought and waterlogging, and cultivate the soil in time: Ginger is not resistant to drought and waterlogging and has strict requirements on water. It is wise to keep the soil moist during the growing period. During the high temperature in summer, it is best to water it in time, especially in the morning and evening. In rainy days, the accumulated water in the field should be removed in time to reduce the occurrence of ginger plague. In order to prevent the roots from sticking out of the ground, the epidermis from thickening and the quality from getting worse, it is necessary to cultivate the soil. Generally, it is combined with watering and fertilization for 2-3 times, about 3 cm each time.

7, do a good job in pest control: diseases mainly include rot and spot disease. Rot disease generally begins in July and peaks in August-September. When the diseased plants are found, they should be pulled out in time, the soil with germs should be dug out, lime should be sprinkled in the diseased holes, and clean sterile soil should be used for landfill. Spraying 50% chlorothalonil solution 800 times at the initial stage of spot disease, and spraying every 7 ~ 10 days/time. The main pests are ginger moth and ginger maggot, and trichlorfon or phoxim is sprayed on the leaves for control.
