What conditions are needed to grow Panax notoginseng? Detailed explanation of the key cultivation techniques
SummaryCultivation conditions: Panax notoginseng is suitable for growing in a humid environment with warm winters and cool summers; the growing process requires diffused light, an average annual rainfall of more than 1200 mm, and air humidity of around 70-85%. Soil preparation and fertilisation: first plough the soil, apply sufficient base fertiliser, then spray New High Lipid Membrane to disinfect the soil. Seed disinfection: select high-quality fruits, remove their skins, wash them clean and dry off the moisture, then disinfect them. Seedling stage management: weed regularly, apply a small amount of additional fertiliser, and water at the right time.
I. Cultivation conditions for Panax notoginseng
1. Panax notoginseng is a shade-loving plant that is neither cold-tolerant nor heat-tolerant, and is suitable for growing in an environment with warm winters and cool summers.
2. Panax notoginseng is relatively sensitive to light and can generally be given diffused light, roughly about 8-20% of natural light. During cultivation and care it needs appropriate shading, and must definitely not be exposed to direct strong light, as this easily causes the plants to be stunted and the leaves to be scorched.
3. Panax notoginseng prefers humidity and is averse to both drought and waterlogging; it is suitable for growing in a humid environment, which requires an average annual rainfall of more than 1200 mm and a relative air humidity of around 70-85%. If the air humidity is low, the leaves are prone to drying out; a soil moisture content of 25-30% is best.
II. Cultivation techniques for Panax notoginseng
1. Soil preparation and fertilisation
(1) It should be grown on gently sloping land with good drainage in humus-rich soil containing abundant organic matter.
(2) After choosing the growing site, plough it to a depth of about 15-20 cm, which helps promote soil weathering; after ploughing, apply sufficient base fertiliser, then spray New High Lipid Membrane to disinfect the soil, which can effectively prevent viral infection and drive away underground pests.
2. Seed disinfection
(1) Each year in October-November, select high-quality fruits borne by 3-4 year old plants, remove their skins, wash them clean and dry the surface moisture, then soak the seeds in an 800-fold New High Lipid Membrane solution for about 10 minutes for disinfection.
(2) Disinfected seeds can reduce viral infection, also repel underground pests and strengthen respiration intensity, thereby increasing the seed germination rate.
3. Seedling stage management
(1) During the seedling stage, weed regularly, apply a small amount of additional fertiliser, and water at the right time; once the seedlings have emerged uniformly they can be transplanted, that is, lifting the seedlings, selecting the seedlings and transplanting them all at the same time.
(2) When lifting the seedlings, be sure to avoid damaging the buds and rootlets; when selecting seedlings, screen out weak, diseased and damaged seedlings, then plant them by grade; before transplanting, dip the roots in an 800-fold New High Lipid Membrane solution, then take them out, let them dry and they are ready for planting.
4. Later stage management
(1) In the later stage, weed and earth up regularly, and keep the bed surface moist at all times; to avoid causing the plants to lodge, when watering do not splash the water but spray it.
(2) When cultivating Panax notoginseng artificially, shade frames must be built in good time; to prevent nutrient loss, fertilise according to the principle of many applications in small amounts.
(3) When the plants produce flower stems, remove them all, and at the same time spray the foliage with the product Gendaling, which helps improve photosynthesis and promote rapid swelling of the rhizome, thereby increasing yield.
5. Pest and disease control
The diseases of Panax notoginseng include: phytophthora blight, aphids, red spider mites, scale insects, damping-off, anthracnose and so on; pesticides can be sprayed in a targeted way, and to improve pesticide utilisation, New High Lipid Membrane can be added to the pesticide, which also guards against drought and rain damage.
