As a very important seasoning, ginger is cultivated all over the country and is an important cash crop in our county. In order to obtain high yield in ginger cultivation, we must grasp several key points:

1、 Choose the right place and soil.

Ginger likes shade and is afraid of strong light. Choose the shady hills on the north slope. At the same time, we should choose fertile loam, avoid yellow laterite and other cohesive soil. Most of our soil, especially dry soil, is residual and slope deposits, with low fertility and thin soil layer. Try to choose the soil with thicker plough layer and turn it as deep as possible.

2、 Rational rotation

Avoid continuous cropping of ginger. Continuous cropping is prone to ginger blast, which is difficult to control, resulting in yield reduction. The continuous cropping of ginger cannot exceed two years, and the rotation crops cannot choose Solanaceae crops such as pepper. If it is a high bank field, it is best to rotate between flood and drought.

3、 Seed selection and disinfection

Ginger should be strong. Before germination, it should be disinfected with agricultural streptomycin to prevent the poison of ginger. Continuous cropping mounds should be disinfected. In the north, chloropicrin is used for disinfection. Our soil basically does not meet these conditions. Agricultural streptomycin and chlorothalonil can be used to disinfect the soil, focusing on the planting ditch of the previous year. Special attention should be paid to clearing the garden, and the residual ginger roots, stems and leaves of the previous year should be completely removed to reduce the source of diseases and pests.

4、 Apply sufficient base fertilizer, sowing and covering

Before sowing, apply enough base fertilizer, 15kg pure nitrogen, 5-8KG phosphorus and 10-15kg potassium per mu. Open field cultivation, sowing before and after the beginning of summer in early May, ginger sowing, bud tip facing down, 2-3 buds per plant, 600-700 kg per mu. The cultivation of protected land can be sown in advance, and sown in sunny days in the middle and late March. For sowing in protected land, pay attention to soil ventilation, and uncover the film in continuous sunny and hot weather to prevent the harm of high temperature. After sowing, it is best to cover with cow manure, 2500-3000 kg per mu. It can not only keep moisture and fertilizer, promote the early growth of ginger, improve the drought resistance of later ginger, but also improve soil fertility and enhance soil permeability, which is conducive to the later growth of ginger tubers, but also reduce the growth of weeds and the occurrence of diseases and pests.

5、 Intercropping weeding, ridge cultivation and fertilization

Take out the seed ginger after the summer solstice. It is OK not to take out the seed ginger, but not taking out the seed ginger will affect the appearance quality of the newly harvested ginger. At the time of harvest, it is necessary to clean up the residual seed ginger, and the residual seed ginger has no value, and the seed ginger taken out at this time has certain commodity value. It is recommended to take out the seed ginger. At the same time, fertilize and cultivate ridges, and use 8-10 kg of pure nitrogen per mu.

6、 Sun shading and moisturizing

Ginger is afraid of strong light, has shallow roots and poor drought tolerance. Especially in August, the weather is dry and the sun is strong. If it is completely exposed to direct sunlight, the ginger will stop growing or even die. If the sun shading and moisturizing work is not done well, the yield can be reduced by 70%. Shading and moisturizing is the key to high yield of ginger. Some farmers use the way of Intercropping Corn for shading, which has poor effect. They must use the way of shading net or artificial shade. If conditions permit, they should water or irrigate as much as possible. In case of flood irrigation, rapid irrigation and drainage must be achieved without waterlogging.

7、 Pest control

There are few diseases and insect pests in ginger, only a small amount of borer damage and ginger blast. The prevention and control of ginger blast should focus on prevention, and agricultural streptomycin can be used for prevention and control after the onset of ginger blast. Some farmers reported that the effect of penicillin was very good.
