Technique of sowing and raising seedlings of Atractylodes lancea

Atractylodes macrocephala is one of the bulk medicinal materials in China, which has high medicinal value and great market demand. It is cultivated all over our country, and seed reproduction is the main method in planting. Raising seedlings is very important when planting, which is related to yield and quality. let's take a look at the seedling techniques of Atractylodes macrocephala.

1. Seedling preparation

The time of raising seedlings is generally in early April, when the land with fertile soil, loose soil and good drainage should be selected as the seedling land, combined with chemical fertilizer or farm manure as the base fertilizer, and the chemical fertilizer had better be diammonium phosphate. Generally, 20 kg per mu can be applied, and it must be spread evenly. Then rake fine leveling, spray some pesticides, so as not to harm the growth of seedlings, made into a 1.2 meters wide, 20 centimeters high seedbed.

2. Seed treatment

First of all, seeds should be selected before sowing, and seeds with full particles, uniform size, bright color and disease-free seeds should be selected carefully, so as to cultivate high-quality seedlings and lay the foundation for high yield. The seeds of Atractylodes macrocephala can emerge in low temperature for about half a month. Soak them in warm water for a period of time before sowing until the seeds grow into small white buds.

3. Sowing seeds

When sowing, the row spacing should be controlled, which should not be too narrow, and the main 15cm should be kept so as not to affect the nutrient absorption of the seedlings. Stir the seeds evenly according to the proportion of 1:5 and fine sand, and sow the seeds evenly on the seedbed, usually using 5 kg seeds per mu. After sowing, cover with a layer of 1cm thick fine soil, cover the soil evenly, cover it with pine needles or straw, and cover it equally thick and thin. In this way, it can not only moisturize, but also avoid the erosion of the rainy season, speed up seedling emergence, and sow seeds for 15-20 days.

4. Seedling stage management

After the seedlings break the soil, you can remove the cover on the surface and pull out the weeds around you. In addition, you have to get rid of some insect seedlings, weak seedlings, diseased seedlings and cultivate strong seedlings. When the seedlings grow to a certain extent, the seedlings should be interspersed and replenished in time, the row spacing should be controlled, and the plant spacing should be controlled at about 3cm. In addition, it is necessary to strengthen fertilizer and water management, watering once a day in the morning and evening, the amount of water should not be too much or too little, maintain an adequate water supply, and fertilizers should not be short of water. Once the disease occurs, the seedlings should be pulled out in time, and we should also pay attention to the change of temperature. if the temperature is too high, we should prepare for shade so as not to cause the seedlings to die due to lack of water.

The above is the introduction of Atractylodes sowing and breeding technology, hope to help you, want to know more planting knowledge, please pay attention to us.
