1. Soil environment
Common Selfheal originally belongs to the category of wild grass and can be seen in all parts of China, which also shows that its growth ability is relatively strong. It can grow normally in almost all kinds of soil, but the main purpose of artificial cultivation is to increase yield and quality. Therefore, before planting, we should choose soil that is fertile, highly loose and rich in organic matter. Suitable soil can further improve the growth capacity of Common Selfheal and increase planting benefits. Common Selfheal likes to grow in a warm and humid environment, so after choosing the site, attention should be paid to doing a good job in land preparation and watering, improving soil moisture and looseness, and then applying sufficient base fertilizer.
2. Seed propagation
The main propagation method of Common Selfheal is seed propagation, and the sowing time of Common Selfheal mainly varies according to the region. For example, in southern regions, sowing is generally carried out around September each year. After choosing the soil, the land should be prepared and beds made, and the specifications of the beds should be controlled according to the soil area. Then mix the seeds with plant ash to improve the germination rate of the seeds. Pay attention to the sowing density and dig the sowing holes well, control the depth of the sowing holes at about 5 cm, then sprinkle diluted manure water into each sowing hole, then evenly sprinkle the seeds into the sowing holes, and cover with a layer of fine soil.
3. Field management
After the sown seedlings emerge and all seedlings are up, apply a thin human manure and urine water in time to promote the growth of the seedlings. When the seedlings grow to about 8-9 cm, do a good job in thinning the seedlings. When thinning, pay attention to the principle of keeping the strong and removing the weak, and then fill the holes with missing seedlings with seedlings of the same growth. The number of seedlings kept in each hole should not exceed 5, and then combined with intertillage and weeding, apply a winter fertilizer. Improve the cold resistance of the seedlings and prevent the seedlings from freezing to death. Finally, in the spring of the second year, carry out intertillage and fertilization again, and water regularly to improve the growth ability of the seedlings.
4. Pest and disease control
Common Selfheal has relatively strong disease resistance, so during the planting process we can use extensive disease control. However, the damage caused by pests to Common Selfheal is relatively great, among which common ones include crickets, aphids, etc. Therefore, during the planting process, we should often observe the growth of Common Selfheal and promptly detect pest problems. Avoid discovering them only when the damage is severe, leading to irreparable losses. After discovering pests, drive them away in time, and pesticides can be used appropriately for control to ensure that Common Selfheal can grow healthily.
The above is a brief introduction to how Common Selfheal should be planted. The planting techniques for Common Selfheal are actually relatively simple. The main thing is to do a good job in management. Careful management is beneficial and harmless, so everyone must pay more attention. That is all for today's introduction.
