At present, many regions in our country grow it, so what should be noted when growing Panax notoginseng? Let us take a look at the detailed introduction below.
1. Growing environment
Panax notoginseng is a shade-loving plant. It likes a warm winter and cool summer environment, fears severe cold and intense heat, and likes a humid environment, but fears waterlogging. The suitable soil moisture content is between 20%-40%. When growing it, pay attention to temperature changes. In summer, the temperature must not be higher than 35 degrees. Once the temperature is too high, in mild cases growth will slow or stop, and in severe cases the plant will wilt and die; in winter, the temperature must not be lower than minus 5 degrees, otherwise frost damage will occur. It grows best in an environment of 18-25 degrees.
2. Land preparation and fertilization
Panax notoginseng has low requirements for soil and strong adaptability, but loose, fertile, well-drained sandy loam soil is suitable. It must not be grown on plots with heavy clay and low-lying areas prone to waterlogging. At the same time, continuous cropping is avoided. The soil pH value is best between 4.5-8. In order to promote the growth and development of the root system of Panax notoginseng, before planting, the soil should be deeply plowed, and the soil should be disinfected and sterilized. At the same time, apply 5000 kg of fully decomposed farmyard manure per mu as base fertilizer to maintain soil fertility.
3. Seedling stage management
What needs attention in seedling stage management is water management and weeding. When the climate is dry, watering should be appropriately increased, generally once a week. In rainy weather, the amount should be reduced. At the same time, pay attention to field waterlogging. If there is waterlogging, drain it to reduce humidity, so as to avoid root rot. Then there is regular weeding. In order to avoid damage to Panax notoginseng, it is best to choose manual weeding and not use pesticides, so as to avoid pesticide residues and affect yield.
4. Pest and disease control
Panax notoginseng has many pests and diseases. Common ones include damping-off disease, root rot, and aphids. These diseases mainly occur in high-temperature and high-humidity environments, so in daily management, be sure to pay attention to field humidity and maintain field ventilation. When diseases are found, promptly spray chlorothalonil or Bordeaux mixture for control. When insect pests appear, spray dimethoate emulsion for control.
