1. Fertilized ginger is the product of continuous cropping, so it should be rotated reasonably when planting. It is necessary to choose land with deep soil layer, loose soil, rich nutrition and rich organic matter for planting. It is required that the terrain of the planting area should be higher, drainage irrigation should be more convenient, and it can be planted in turn with bean crops such as rice. In the process of land improvement, it is necessary to apply base fertilizer to ensure that ginger grows vigorously and has sufficient nutrients, so as to increase the yield. Apply 3000 kilograms of organic fertilizer or 50 kilograms of suitable farmyard manure per mu of land, and then spread these fertilizers evenly on the soil. These fertilizers should be mixed with the soil during cultivation.

2. When choosing sprouted ginger pieces, you must choose the one with plump appearance, good color, fresh texture, no disease and strong 1-2. As a seed, the optimum weight of germinated ginger is about 60 grams. Before sowing, use drugs to sterilize and accelerate germination, and make the seedlings neat with the help of germination rate. We can first soak 50% carbendazim in 500 times solution for disinfection. After disinfection, put it in sunny weather for about two days. When its surface is bright and shiny, you can pile it up to accelerate germination, pile them together, and then cover them with straw to keep their temperature around 23 degrees Celsius. At the same time pay attention to wetting. When the ginger buds grow to about 1 cm, you can sow.

3. The best sowing date should be around Tomb-Sweeping Day. When sowing, the method of drilling is adopted, and the row spacing of each plant is controlled at 40 cm long and 30 cm wide, so as not to hinder the growth. The ditch depth should be controlled at about 15cm, and generally about 450kg should be planted per mu. When sowing, appropriate fertilizer should be applied as seed fertilizer, and the dosage should be controlled at the same time. This is to make them germinate quickly, and then apply fertilizer evenly into the ditch and mix it with the soil in the planting area. Before sowing, water should be poured once to keep the soil moist. Then, put the ginger slices flat in the ditch, the direction of germination is upward, and then press them in the soil and cover them with 5 cm of soil. After sowing, level the soil.

4. Fertilize and water scientifically after fertilization, and ginger can't be topdressing during germination. When one or two branches are sent out and the seedlings grow to twenty or thirty centimeters, topdressing should be done in time. Generally speaking, appropriate ammonium sulfate is applied per acre. The second topdressing is in the swelling period of ginger slices, at which time ginger slices need a lot of nutrients to grow and swell. At this time, it is necessary to apply appropriate fertilizer to each mu of land, about 1.25 kg. One thing to pay attention to when watering is not to water too much, but to irrigate frequently, and usually to keep the water content of the soil within 70%. When the temperature is high in summer, the water in the soil will evaporate quickly. Therefore, it is necessary to water frequently to maintain the existence of water. It's best to water in the early morning or evening when the sun just goes down, and avoid the highest temperature at noon, in case we evaporate just after watering. In rainy weather, it is best to take drainage measures and flood prevention measures. Ginger grows faster in autumn, so it needs a lot of water. In this case, we usually water once a week, at least once, so that the water content of the soil reaches about 80%.
