Detailed Explanation of Pseudostellaria heterophylla Planting Techniques and Management Key Points
Pseudostellaria heterophylla, also known as hai'er shen or tong shen, is a commonly used traditional Chinese medicinal herb unearthed in China, with the effects of tonifying qi and strengthening the spleen, promoting fluid production and moistening the lungs, and is deeply favored by physicians. With the improvement of people's living standards and growing health awareness, medicinal drinks and medicinal meals made from Pseudostellaria heterophylla have become fairly common among the public, leading to a sharp increase in demand, soaring market prices, and also promoting its cultivation. So how should Pseudostellaria heterophylla be planted? Let's find out together.
1. Land Selection and Preparation
Pseudostellaria heterophylla likes to grow in warm and humid environments, prefers fertilizer, fears waterlogging, and fears drought, so it is advisable to choose plots with higher terrain, fertile and loose soil for planting. Waterlogged land with poor drainage and saline-alkali land are not suitable for planting. The previous crop of the plot is best to be sweet potato, vegetables, and other crops. After the previous crop is harvested, plow the plot. When plowing, apply farmyard manure as base fertilizer, and turn it into the soil together with the plowing. After raking fine and leveling, make raised beds.
2. Propagation Methods ⟧7⟧There are many propagation methods for Pseudostellaria heterophylla, and the commonly used ones are seed and tuber propagation methods. For tuber propagation, when harvesting, select roots with complete and undamaged buds as the best. Open furrows on the bed surface, place the tubers obliquely or flat on one side of the furrow, with the bud heads positioned consistently, then cover with soil. The thickness of the soil cover is quite important: if too deep, the roots will be large but few in number and the yield will be low; if too shallow, the roots will be small and the quality poor. A depth of 5-6cm is appropriate. Seeds are not easy to collect, so naturally dropped seeds are often used to raise seedlings on the spot. After cultivation in the same place and harvest, rake the plot level, apply fertilizer, and plant a crop of radishes, vegetables, etc. After harvesting, rake level again, and at this time the seeds will germinate and emerge. When they grow to have 3-4 leaves, they can be transplanted.
There are many propagation methods for Pseudostellaria heterophylla (heterophylly falsestarwort), and the commonly used ones are seed and tuber propagation. For tuber propagation, when harvesting, it is best to select roots with intact, undamaged buds. Open furrows on the raised bed surface, place the tubers obliquely or flat against one side of the furrow, keeping the position of the buds consistent, then cover with soil. The thickness of the covering soil is fairly important: if too deep, the roots grow large but are few in number and yields are low; if too shallow, the roots are small and of poor quality. A depth of 5-6 cm is appropriate. The seeds are not easy to collect, so the seeds that fall naturally are often used to raise seedlings in place. After cultivation and harvest in the same spot, rake the plot level, apply fertilizer, and plant a crop of radishes, vegetables, etc. After harvesting, rake it level again; the seeds will then germinate and emerge, and once they have grown 3-4 leaves they can be transplanted.
3. Field Management
After emergence, timely carry out intertillage and weeding. If the planting area and weeds are small, manual pulling is recommended; if the planting area is large and there are many weeds, chemical weeding can be used, but pay attention to the concentration of the agent. Pseudostellaria heterophylla fears waterlogging; once the soil accumulates water, it is very prone to rot, so after rain it must be drained in time. During drought, it should also be irrigated in time to facilitate plant growth. If the plants grow slowly or are weak, appropriately apply additional human feces and urine or ammonium sulfate.
4. Pests and Diseases
The main diseases of Pseudostellaria heterophylla include root rot, leaf spot, and mosaic disease, mostly caused by high-temperature and high-humidity environments, so when planting, be sure to choose plots with good drainage and ventilation, and spray pesticides in time to prevent and control diseases once they occur. Pests include white grubs, cutworms, mole crickets, and wireworms. They mainly damage the plants, affect yield, and in severe cases cause the aboveground parts to wither and die. For these, insecticide can be diluted with water and poured on the roots, or toxic soil can be made to kill them.
