Management Techniques for Daylily After Harvest
Daylily is a relatively precious wild vegetable in China, distributed throughout the country. It has effects such as reducing inflammation and clearing heat, and improving eyesight and calming the mind. It is a wild vegetable with very high nutritional value, and now artificial cultivation has gradually begun. Daylily's growth period is in spring and autumn, and after harvest it gradually enters dormancy, but this period is quite important. Only with good management can high yields be guaranteed year after year. Now let's take a look at the management techniques for daylily after harvest!
1. Pulling up stalks and cutting leaves
After harvest, the stems of daylily gradually dry up, and we should promptly pull out the stems, but we must also pay attention to the condition of the stems. Do not pull out stems that have not completely dried, to avoid damaging the roots. At the same time, cut off the old leaves about 4 cm above the ground; do not cut too low, otherwise it will hinder the sprouting of latent buds. If cut too high, it will consume too much nutrition, so the distance must be well controlled. Pulling up stalks and cutting leaves can promote the growth of seedlings, increase the number of flower stalks the following year, and greatly help increase yield.
2. Clearing the field and disinfecting ⟧7⟧Daylily often suffers from leaf blight, aphids and other pests and diseases during cultivation, so we should do a good job of clearing the field and disinfecting in autumn and winter, which can effectively prevent and control pests and diseases. If there are still cases of disease after harvest, then disinfection should be carried out separately in autumn and winter, remove weeds in the field, and then burn them together with the diseased plants and diseased leaves of daylily. Then mix the ash into the soil, which not only reduces the sources of pests and diseases, but also improves soil fertility.
During the cultivation of daylily (Hemerocallis citrina), pests and diseases such as leaf blight and aphids often occur, so we should carry out thorough garden cleaning and disinfection in autumn and winter, which can effectively prevent and control pests and diseases. If the disease still occurs after harvest, then disinfection should be carried out separately in autumn and winter, removing the weeds in the field, and then burning them together with the diseased plants and diseased leaves of the daylily in a centralized manner. Then mix the ash into the soil, which not only reduces the sources of pests and diseases, but also improves the fertility of the soil.
3. Deep plowing and fertilizing
After the entire growth period of daylily, due to field management work, the soil has been trampled for a long time, resulting in soil compaction. Therefore, we should choose sunny days in summer to deep plow the soil, promote the growth of autumn seedlings, improve root capacity, and enhance plant growth. First dig out the area around the plants, then remove the old roots and dead roots, and then fill it back level to prevent the roots from being exposed and avoid root burn. During deep plowing, apply it together with base fertilizer, control the amount well, improve soil fertility, and promote seedling growth.
4. Renewal and rejuvenation
Summer rainfall is abundant, which is very beneficial for daylily renewal. First, we should select daylily with weak growth, dense roots and few new roots, and thin and weak plants for replanting. Then burn the areas with severe pest and disease outbreaks, and replant healthy seedlings. The planting area can also be appropriately expanded, and impure varieties should be eliminated in time to ensure healthy growth of daylily, increase yield, and enhance quality.
5. Earthing up and protecting the clumps
During cultivation, daylily can be harvested multiple times a year. New roots grow from each year's new stems. If earthing up is not done in time, they will keep growing upward and be exposed to the air. Therefore, in winter we must do a good job of earthing up, preferably using pond silt and rice field mud, or the original cultivation soil. Keep the new roots warm, improve cold resistance, prevent freeze damage, and reduce the production of ineffective tillers.
The above is a brief introduction to the management techniques for daylily after harvest. Since daylily is a polycarpic perennial, the management work after each harvest is very important. Improper management will seriously hinder subsequent growth, reduce yield, and lead to a decline in planting benefits. That is all for today's introduction. This article is for reference only.
