Detailed Explanation of the Key Cultivation and Management Techniques for Agrimony
Agrimony, also known as hairy agrimony, is a perennial herbaceous plant in the Rosaceae family and also a medicinal herb. Its whole plant can be used as medicine, and it has functions such as astringing to stop bleeding, reducing inflammation and detoxifying. Although it is widely distributed in China, with the increase in demand, the planting area of agrimony is now also continuously increasing. So how should agrimony be managed when planted? Below, the editor brings you the cultivation and management methods for agrimony. Let's take a look together!
1. Thinning and final singling of seedlings
The work of thinning and final singling of seedlings is very important for the growth of agrimony. When the seedlings grow to about 4 cm, they should be thinned in time. When thinning, the principle is to keep the strong and remove the weak, ensuring that each seedling has sufficient space to grow. Promptly pull out seedlings that are growing too densely, then when the seedlings grow to about 15 cm, carry out final singling with the plant spacing controlled at 16 cm. If the planting purpose is for root buds, then the plant spacing should be appropriately expanded to promote root growth and increase yield.
2. Intertillage and weeding
The seedling growth capacity of agrimony is relatively weak, so we must promptly do a good job of intertillage and weeding. Intertillage can not only improve soil looseness and promote seedling growth, but also achieve the purpose of weeding, avoiding rampant weeds competing for the nutrients needed for seedling growth. Reasonable intertillage and weeding is the key to ensuring healthy growth of agrimony and increasing yield. However, after the plants close the rows, intertillage should be stopped, but weeding should still be carried out in time.
3. Timely topdressing
Nutrition is indispensable for the growth of agrimony, and topdressing must be done well during the planting process. Before final singling, topdressing should be applied once to promote nutrient absorption by the seedlings, and topdressing should be applied again before the rows close. Then, topdressing should be applied reasonably according to the growth condition of agrimony and the soil fertility level. Topdressing should be applied once every spring and after harvest. If the planting purpose is for the whole plant, the amount of nitrogen fertilizer can be appropriately increased. The type and amount of fertilizer should be controlled according to the planting purpose.
4. Timely flower removal
Agrimony has a relatively large flowering volume, but the flowers of agrimony are not very useful. Therefore, when planting, attention should be paid to doing a good job of flower removal, because agrimony has a large flowering volume and also consumes relatively more nutrients. Therefore, if the flowers are not removed in time, they will compete for the nutrients of the roots, which will have a relatively large impact on root growth. So when flower stems appear, the flowers should be removed in time. However, attention should also be paid to retaining some plants for seed production, and plants retained for seed production must not have their flowers removed.
5. Seed collection and seed retention
When planting, a good seed production field should be established, or robust plants with healthy aboveground parts should be selected from the main field for seed retention. Increase the frequency of fertilization and strengthen field management. Agrimony generally flowers around June each year. When the seed color gradually deepens and dries in August, cut the plants, take out the seeds, and then place them in a ventilated and dry place for storage and seed retention.
The above is a brief introduction to the cultivation and management of agrimony. We also need to do a good job of pest and disease control for agrimony. Pests and diseases are very harmful to agrimony, so everyone must pay special attention to avoid unnecessary losses. That is all for today's introduction. This article is for reference only.
