How to Plant Platycladus orientalis Seeds? Cultivation Methods and Key Technical Points
Baiziren is the dried, mature seed kernel of Platycladus orientalis (Chinese arborvitae), a plant in the Cupressaceae family. It can be harvested twice a year, in autumn and winter. At present, Baiziren is mainly distributed in Guangdong, Shaanxi, Guizhou and other parts of our country. Baiziren has the effects of nourishing the heart and calming the mind, and moistening the intestines to relieve constipation, and can be used to treat insomnia, constipation and other conditions. However, what we are going to discuss today is not its effects and benefits; the most important thing is to understand its cultivation techniques. Let's take a look together.
1. Site Selection and Land Preparation
Baiziren generally grows in areas with moist soil and fertile soil texture. When choosing a planting site for Baiziren, we usually need to analyze it in combination with its growth habits. Baiziren is best planted in neutral soil with ample sunlight, shelter from the wind, and well-developed irrigation conditions. After choosing the planting site, we should carry out fine tillage and prepare the land in strict accordance with the requirements for planting Baiziren. During land preparation, apply base fertilizer at the same time, make ridges properly, dig drainage ditches well, and finally break up the soil clods and rake the surface level.
2. Cultivation Techniques
Baiziren is generally propagated by seed. Before sowing, soak the seeds in warm water at about 30 to 40 degrees; after 12 hours, remove them and place them in a ventilated place for germination. During the germination process, we should rinse them with clean water once a day, and then when half of the seeds have opened, they can be sown. When sowing, we follow a row spacing of 6 to 10 cm; after sowing and covering with soil, seedlings will emerge in about half a month.
3. Planting Management
After sowing, we should water appropriately to keep the soil moist, which can increase the seedling emergence rate of the seeds. After the seedlings emerge, in general, watering once about every half a month is sufficient, and the seedling cultivation period is generally about one year. When the seedlings grow to about 30 cm, they can be transplanted and planted out. However, since Platycladus orientalis grows every year, the planting density differs each year. Generally, at the beginning, the planting density is about 2 m between rows and about 1.5 m between plants. After planting, water to promote the growth of new roots, and at the same time apply additional fertilizer appropriately. In addition, it is necessary to avoid human-caused damage to Platycladus orientalis that would affect its growth.
4. Pest and Disease Control
During the growth of Baiziren, we mainly need to prevent harm to Platycladus orientalis from the arborvitae tussock moth, red spider mite, Semanotus bifasciatus (double-striped Japanese cedar longhorn beetle), and the pine shoot small tortrix moth. In this process, we can usually use fenitrothion emulsion, tetradifon wettable powder, zinc phosphide, and trichlorfon for control, and the results are all very good.
In fact, growing Platycladus orientalis is very simple; it only has certain requirements for planting conditions. That is to say, during the planting process, we only need to pay attention to the selection of planting conditions and to certain detailed issues during planting. That is all for today's content that the editor wants to share. Thank you all for reading.
