How to Grow Phryma leptostachya? A Complete Analysis of Planting Methods and Key Technical Points
Phryma leptostachya, also called Yaoqucao, is a perennial herbaceous plant. It has high medicinal value, and the whole plant is used as medicine; it can be used to promote blood circulation and remove blood stasis, induce diuresis and detoxify, and unblock meridians and penetrate bones. It also has a certain therapeutic effect on sores, boils, swelling and pain, and insect bites. It has strong adaptability to the environment and grows quickly, and can be planted in most areas of our country. So how do you grow Phryma leptostachya? Today let us learn about it together.
1. Land Selection and Plowing
Phryma leptostachya has the characteristics of preferring warmth and moisture, tolerating barren soil, tolerating fertile soil, tolerating saline-alkali soil, liking light, and fearing waterlogging. It does not have high requirements for soil, and general land can be used for planting, but it is best to choose sandy loam soil for planting, with a well-developed drainage system at the same time. With fine plowing, well-dug water ditches, ditches connected to one another, sufficient base fertilizer applied, the ground leveled, and soil clods broken up, sowing can then be carried out.
2. Scientific Sowing
The planting time for Phryma leptostachya is generally around Qingming Festival. The day before sowing, the land needs to be watered thoroughly, and then shallow furrows should be made. The furrow depth is about three to five cm, and the distance between each furrow is about fifteen to twenty cm. Then sow the seeds evenly in the shallow furrows, with a seed spacing of about five cm, and cover with soil to hide the seeds. During the period when Phryma leptostachya emerges, we must maintain soil moisture and water in time.
3. Field Management
Generally, seedlings emerge about thirteen to fifteen days after sowing. When the seedlings grow to about six to eight cm, thin them out, and set plants at a spacing of ten cm between each plant, keeping three to four seedlings per hole. At the same time, replant missing seedlings or relatively sparsely grown areas in the field, and water them to ensure the survival rate of the seedlings in the field. Phryma leptostachya has a relatively large demand for water, but when watering, we should follow the principle of frequent light watering. In order to improve the yield and quality of Phryma leptostachya, during its growth period, it generally needs at least three to four topdressings, mainly nitrogen fertilizer each time.
4. Pest and Disease Control
Phryma leptostachya has relatively strong disease resistance, so generally there are no pests or diseases. However, sometimes when field management is not in place, or when disease prevention measures are not done well before planting, certain pests and diseases can also appear. For example, powdery mildew and white butterflies are the most common. For powdery mildew, we can use triadimefon for control, while for white butterflies, dimethoate emulsifiable concentrate can be used to kill them.
