Detailed Explanation of the Key Field Management Techniques for Growing Fiddlehead Fern
Fiddlehead fern is a very popular wild vegetable in China and holds a very high status in the country. Due to increased market demand, people have been harvesting and digging it without restriction, causing wild populations to decline sharply. Therefore, fiddlehead fern now also has a certain amount of cultivated area, but because it is a wild vegetable, many people do not know how to manage it when growing it. So below, the editor brings you the field management techniques for fiddlehead fern. Let's take a look!
1. First-year management
In the first year of fiddlehead fern cultivation, good work must be done to establish the seedlings, ensuring strong and uniform seedlings, timely weeding, and strengthened water and fertilizer management. Before planting, first water thoroughly to improve the survival rate of fiddlehead fern, and to prevent the soil from lacking water, it is also necessary to water frequently to increase the soil's moisture content. However, the amount of water should not be too much. If too much water is applied or if the rainy season comes, then drainage should be done in time to prevent excessive water accumulation from causing damage. Then appropriately cover the soil with straw, leaves, or plastic film to do a good job of shading and heat preservation, and it can also inhibit weed growth. When fiddlehead fern grows new shoots, apply topdressing once a month.
2. Second-year management
The main direction of management in the second year is to cultivate high-quality roots and promote the formation of multiple buds on the fiddlehead fern roots. Then, according to the nutritional needs of fiddlehead fern and the soil fertility conditions, apply fertilizer and weed reasonably. When applying topdressing, pay attention to the amount; it must not be too much at one time, and it is mainly better to apply more frequently in small amounts. The fertilizer is mainly urea, which can effectively promote the reproduction of underground rhizomes. In the second year, harvest only a small amount, and if possible, it is best not to harvest at all. Then in autumn, apply farmyard manure, do a good job of loosening the soil, and mix it thoroughly with the soil. This can not only improve soil fertility and enhance soil quality, but also improve the soil's cold resistance and heat preservation.
3. Third-year management
In the third year, the growth ability of fiddlehead fern gradually strengthens, and at the beginning of the year, one intertillage and weeding operation should be carried out. This prevents too many weeds from robbing the nutrients needed for fiddlehead fern growth, and in the following year, regular intertillage and weeding should be carried out. This can not only improve soil permeability and promote nutrient absorption by the roots, but also concentrate nutrients on the fiddlehead fern. Then water and fertilizer work should also be done well, appropriately applying farmyard manure, and reducing or stopping the use of pesticides and chemical fertilizers, to improve the quality of fiddlehead fern and promote the formation of pollution-free green food.
4. Fourth-year management
In fact, management in the fourth year is similar to that in the third year, because by this time fiddlehead fern is almost ready for harvest. What should be noted is that in order to prevent grass overgrowth, we should weed about 4 times to reduce the number of weeds in the field, and it is best to achieve a weed-free condition. During its growth period, the main weeding target is to pull out those taller weeds to avoid a relatively large impact on fiddlehead fern growth. Then in autumn, after it withers, break the plants and lay them on the soil like weeds for heat preservation. Finally, pay attention to pulling out diseased and pest-infested plants, then take them out of the garden and burn them.
The above is a brief introduction to the key field management points for fiddlehead fern. The growth cycle of fiddlehead fern is very long, and one planting can allow harvesting for about 10 years. Harvesting generally takes place in spring and summer each year, and it must never be harvested too late, as this will not only reduce its commercial value but also affect the next year's yield. That is all for today's introduction. This article is for reference only, and I hope it can be helpful to everyone!
