The Latest Cultivation Methods and Techniques Tutorial for Pseudolarix Bark
Pseudolarix bark is the dried root bark and the bark near the roots of the golden larch (Pseudolarix amabilis), a plant in the Pinaceae family. It has bactericidal and antibacterial effects and is also a type of medicinal material. At present, the main producing areas of Pseudolarix bark are Jiangsu, Anhui, Zhejiang, Hunan, Hubei and other places in China. So do you know how Pseudolarix bark is propagated? How should Pseudolarix bark be planted to grow well? How should field management be carried out? The content I want to share with you today is the cultivation techniques for Pseudolarix bark. Let's learn about it together.
1. Site Selection and Land Preparation
Pseudolarix bark prefers warmth, shade and moisture, is not cold-tolerant, and avoids strong light. Therefore, when choosing a planting site for Pseudolarix bark, we need to decide based on its growth habits. Generally, we choose semi-shaded sandy loam with fertile soil, rich humus content, good water source conditions, good fertilizer and water retention, good soil aeration and good drainage for planting. Land preparation should be combined with the application of base fertilizer. The base fertilizer is mainly organic fertilizer, and the amount is generally controlled at about 1,500 kg per mu. Finally, break up the soil clods finely, level the ground, then open furrows and make beds, and wait for planting.
2. Propagation Methods
Although Pseudolarix bark can also be propagated from seed, its growth and development rate is very slow, so in ordinary cultivation we basically use the cutting propagation method. Cutting propagation is generally carried out in spring or summer each year. First, select robust, pest-free, high-quality rhizomes or stems of Pseudolarix bark; then cut the cuttings into small sections of 5 cm, ensuring that each small section has 2 to 3 buds; finally, insert the cuttings at a row spacing of 15 cm and a plant spacing of 2 cm, and water once.
3. Transplanting and Field Planting
After Pseudolarix bark is propagated by cuttings, it generally needs 2 to 3 months of cultivation to grow several new roots. Only when the Pseudolarix bark seedlings have grown to about 10 to 15 cm can we transplant them. When transplanting, they should generally be planted at a reasonable density so as to ensure the later growth of Pseudolarix bark, with row spacing controlled at 25 to 30 cm and plant spacing controlled at about 20 to 25 cm.
4. Field Management
After the plants survive field planting, we should ensure at least 3 to 4 times of cultivating and weeding every day. The timing of cultivation is generally determined by the growth condition of Pseudolarix bark, the growth condition of weeds in the field, and changes in soil permeability caused by rain or watering. Topdressing should be carried out at least 2 to 3 times a year. Depending on the growth period of Pseudolarix bark, it is generally mainly nitrogen fertilizer, combined with an appropriate amount of phosphorus and potassium fertilizer. Then attention should be paid to moisture retention, with watering carried out irregularly. In addition, during the growth process of Pseudolarix bark, moderate light control is also needed. Diffused light should be used, with intensity generally around 20% to 30%. Finally, there is pest and disease control. The most important is generally leaf spot disease, which can be controlled by spraying with Tuzet.
Growing Pseudolarix bark is actually very simple, because its adaptability to the environment is still relatively strong. However, during the planting process, we also need to pay attention to some issues so as to ensure that Pseudolarix bark grows better.
