Detailed Explanation of the Cultivation Techniques and Methods of Panax japonicus
Panax japonicus is a precious traditional Chinese medicinal herb in China. In recent years, as market demand for it has grown larger and larger, its price has gradually climbed, and many regions have begun to cultivate it as a project for getting rich. So how should Panax japonicus be cultivated? Let's take a look at the detailed introduction with the editor.
1. Site Selection and Land Preparation
Panax japonicus prefers loose soil, good drainage, a certain slope, and soil rich in humus. It fears waterlogging and heavy clay soil, and continuous cropping is taboo. Therefore, when planting, choose a sandy loam or humus soil with good drainage, a slope of 5-20 degrees, and a pH value between 5 and 7. The planting site should be sheltered from the wind and facing the sun, and the previous crop should preferably be corn, flowers, and soybeans. After selecting the site, plow it in summer to make the soil fine and fully weathered, and increase strong light to kill soil-borne pest and disease sources. During the final plowing, apply 2000-3000 kg of decomposed farmyard manure per mu as base fertilizer, then shape and rake it level to make high beds.
2. Propagation Methods
Propagation methods for Panax japonicus include seed propagation and vegetative propagation, but seed propagation takes as long as 6 years from sowing to harvest, which is too long, so vegetative propagation is generally the main method in production. Vegetative propagation mainly uses plant rhizomes cut into sections for propagation. Panax japonicus has strong regenerative ability, and whether it is the terminal node, middle node, or the rhizome bud of Panax japonicus, all can be used for vegetative propagation. It is generally carried out in October in autumn. Dig out the rhizomes, cut them into small sections, and according to the sowing method, open furrows or holes on the bed surface and sow the seed rhizomes into them.
3. Field Management
Check promptly at emergence, and when poor emergence is found, replant in time. At the same time, remove diseased and weak seedlings to ensure that the seedlings grow robustly. After the seedlings are uniform, loosen the soil and weed in time to ensure there are no weeds in the field and promote root growth and development. After loosening the soil, if rhizomes are found to be exposed, earth up in time to ensure normal plant growth. Fertilizer and water management should also be done well. Water in time during drought to keep the bed surface moist, and take drainage measures during the rainy season. Cultivated Panax japonicus needs 1-2 topdressings per year to promote its growth and increase yield.
4. Pest and Disease Control
The main diseases of Panax japonicus include phytophthora blight, damping-off, and root rot. Control should adopt a combination of agricultural control and chemical control. Pay attention to drainage during the rainy season to avoid root damage, which would give diseases an opportunity to invade. Pull out diseased plants in time and take them out of the field, and disinfect and sterilize the diseased holes. If the disease causes large-scale damage, spray the corresponding chemical agent for treatment according to the corresponding disease. The main pests include white grubs, cutworms, and mole crickets, which mainly damage rhizomes and seedlings. For control, methods such as drenching the roots with dichlorvos or phoxim emulsifiable concentrate can be used.
