The Latest Guide to Post-Harvest Management Techniques for Daylily
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 artificial cultivation is now gradually beginning. Daylily's growth period is in spring and autumn, and after harvest it gradually enters a dormant period, but this period is relatively important. Only with good management can high yields be ensured year after year. So let's take a look together with the editor at the post-harvest management techniques for daylily!
1. Pulling up stalks and cutting leaves
After harvest, the stems of daylily gradually dry up. We should remove the stems in a timely manner, but we should also pay attention to the condition of the stems. Do not pull out stems that have not yet completely dried, to avoid damaging the roots. At the same time, cut off 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 garden and disinfecting
During cultivation, daylily often suffers from leaf blight, aphids and other pests and diseases, so we should do a good job of clearing the garden 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 from the field, then burn them together with diseased plants and leaves of daylily in a centralized manner. Then mix the ash into the soil, which not only reduces sources of pests and diseases, but also improves soil fertility.
3. Deep ploughing 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 carry out deep ploughing of the soil, promote the growth of seedlings in autumn, improve root capacity, and enhance plant vigor. First dig out the area around the plants, then remove old roots and dead roots, and then fill it back level to prevent the roots from being exposed and avoid burning the roots. During deep ploughing, apply it together with base fertilizer, control the amount used, improve soil fertility, and promote seedling growth.
4. Renewal and rejuvenation
Summer has high rainfall, which is very favorable for renewal of daylily. First, we should select daylily with weak growth, dense roots and few new roots, and thin plants for replanting. Then burn 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 a timely manner to ensure healthy growth of daylily, increase yield, and enhance quality.
5. Earthing up to protect the root crown
In 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 paddy field mud, or the original cultivation soil. Keep the new roots warm, improve cold resistance, prevent freezing damage, and reduce the production of ineffective tillers.
The above is a brief introduction to the post-harvest management techniques for daylily. Since daylily is a 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.
