How to sow and raise seedlings of Atractylodes lancea? A full analysis of the key technical points
Atractylodes lancea is one of China's major bulk medicinal materials, with extremely high medicinal value and huge market demand. It is cultivated in all parts of China, and seed propagation is generally the main method used when planting. Raising seedlings is extremely critical during cultivation, as it affects both yield and quality. Let's take a look at the seedling-raising techniques for Atractylodes lancea below.
1. Seedbed preparation
The time for raising seedlings is generally in early April. At this time, choose a plot with fertile soil, loose texture and good drainage as the seedling bed. Combine soil preparation with the application of chemical fertilizer or farmyard manure as base fertilizer. The chemical fertilizer is best diammonium phosphate, generally applied at 20 kg per mu, and it must be spread evenly. Then rake it fine and level it, and spray some insecticide to prevent underground pests from harming seedling growth, then make seedbeds 1.2 m wide and 20 cm high.
2. Seed treatment
Before sowing, first select seeds. Seed selection must be done carefully, choosing seeds that are plump, uniform in size, bright in color and free of disease, so that high-quality seedlings can be cultivated and a foundation laid for a high yield. Atractylodes lancea seeds can emerge in about half a month under low-temperature conditions. Before sowing, soak them in warm water for a period until the seeds grow small white sprouts, and then they can be sown.
3. Sowing
When sowing, control the plant and row spacing; it should not be too narrow. Keep it mainly at 15 cm to avoid affecting the seedlings' absorption of nutrients. Mix the seeds evenly with fine sand at a ratio of 1:5, and spread the seeds evenly on the seedbed. Generally, 5 kg of seed is used per mu. After broadcasting, cover with a 1 cm thick layer of fine soil, and the soil covering should be even. After covering with soil, cover with pine needles or rice straw, and this covering should also be evenly thick. This can both preserve moisture and avoid washing away during the rainy season, speeding up emergence. Seedlings can emerge 15-20 days after sowing.
4. Seedling-stage management
After the seedlings break through the soil, the surface covering can be removed, and the weeds around them can be pulled out. In addition, some insect-damaged, weak and diseased seedlings should be removed to cultivate strong seedlings. When the seedlings grow to a certain extent, thin and fill in seedlings in time, and control the plant and row spacing, with plant spacing controlled at about 3 cm. In addition, strengthen fertilizer and water management, watering once in the morning and once in the evening. The amount of water should not be too much or too little, maintaining a sufficient water supply, and fertilizer should not be lacking either. Once diseased seedlings appear, pull them out in time. Also pay attention to temperature changes. If the temperature is too high, make preparations for shading to prevent strong sunlight from causing water loss and death of the seedlings.
