cultivation of virgin soil
The adaptability of the raw land is strong, and the planting sites can be selected in many ways to maintain sufficient light; the soil with good drainage performance can be selected for crop rotation such as sorghum and vegetables. Fertilization is mainly phosphorus and potassium fertilizer, according to the growth of appropriate watering. Pull out weeds in the field in time, and control diseases and insect pests rationally.
The planting of raw land
1. Land selection and preparation
Raw land is suitable for planting in loose and fertile soil. If the soil is sticky or hard, it will affect its root growth and yield, while if the soil drainage is not good, it is easy to accumulate water, which will lead to root rot, in addition, continuous cropping, it is best to rotate with sorghum, vegetables, cotton and other crops for 3-4 years.
2. Seed selection and planting
After seed selection, fold it into a small section about the size of 5cm and let it dry for 1-2 hours, so that the wound can be sown after healing. Sowing is reasonable and close planting, generally about 100kg of seeds per mu, covering soil 5-7cm after sowing and watering. In low temperature areas, the ground temperature can be increased by covering the ground. As long as the temperature and water are suitable, seedlings can generally emerge in 25-30 days.
3. Fertilizer and water management
When fertilizing raw land, more phosphorus and potassium fertilizer should be applied, and sufficient base fertilizer is also extremely important for yield. in order to make the seedlings grow rapidly, it is necessary to top fertilize at the same time, then 15 kg of urea is applied per mu, which can be washed in dissolved water, and in the middle of growth, that is, in July, when topdressing phosphate fertilizer is 10-20 kg per mu.
4. Field management
When the seedlings grow above 10cm, one plant should be left in each hole. If the seedlings are missing, the seedlings should be replenished, and the seedlings should be carried out in cloudy days, and it is best to transplant them with soil. In the early stage of plant growth, the seedling is too small, and the root system is relatively shallow, so weed should be removed so as not to affect the seedling growth.

How to raise the old pile
The nursing pile should use a larger basin to make its roots stretch. Then fertilization should focus on the application of nitrogen and potassium fertilizer to ensure the nutrition of the old pile, and attention should be paid to the principle of frequent application of thin fertilizer. In addition, to ensure sufficient light, the basin is slightly moist without stagnant water is also the weight of the old pile.

Tiger ginger is generally planted by seed sowing and underground rhizome planting. Among them, the seeds matured in August of the first year should be selected for seed sowing, and the seeds should be sown in late March of the following year, while rhizome planting should be carried out around late autumn or early spring late March.
