First, the venue selection Osmunda grew wild in the woods, has formed a good habit of hi wet, moisture requirements are more stringent, and hi acidic soil. Therefore, in the wet and fertile humus under the forest, the growth and germination are early, the growth is fast, and the leaves are tender and long. Second, planting methods Artificial cultivation of more use of rhizome transplanting method, that is manually excavating wild Osmunda rhizome, with transplanting to the selected planting area. This method can be divided into transfer method, good uniformity of relocation, rapid growth, early production, high yield, but also easier to grasp. Its specific approach is: in the selected planting field in the winter to open a good fire line to carry out the mountain, choose a sunny day to burn well burned, after burning the ground shallow control 5-6 cm, the roots, grasshoppers eradicate, full enough The farmyard manure was grown at a height of 1.2-1.4 meters, and then the roots of wild vegetables were planted at a spacing of 33-40 cm and planted at 667 m2 and planted at 4166-6000 m. Set the root water. The key to this method is: (1) The roots and stems of wild Osmunda operculata are required to be about 10 mm in length and about 20 cm in length, dig out with soil, and retain moisture. The day of excavation is transplanted on the same day to ensure the survival rate; (2) the depth of transplant is planted. After the upper cover is about 2 cm thick, it is appropriate; (3) The applied farm manure must be fully decomposed after stacking so as to avoid fermentation of high-temperature watering roots. III. Post-planting management (1) Top dressing can be done before budding (about the beginning of February in the lunar calendar), and after rainy or rainy days, 667 square meters of imported compound fertilizer with NPK share 15% 50-100 kg (conditional Can add some grass ash) for applicator; When the seedling height is 50 centimeters, then 667 square meters topdressing 1,000 kilograms of thin human feces and urine; in the late autumn and early winter when you can apply some organic fertilizer in order to facilitate the winter. (2) When the watering height is 25 cm, 50 cm and 70 cm, each time it is poured, it can be significantly increased. In the rainy season, drainage work should be done in time to prevent flooding. (3) Shading A high-stem crop, such as corn, is planted around the raft and used as a sunshade, which is conducive to the growth of Osmunda. (4) Cover the grass with cold hay and deciduous trees before entering the winter to keep it safe for the winter. Fourth, the harvested Osmunda is generally not harvested in the current year and it is not until the second year that harvesting begins. When the petiole of the young leaf grows to 20-25 cm, it should be harvested, otherwise the base of the leaf will become fibrotic and the commodity value will be low. If the roots are not damaged during harvesting, new shoots can continue to emerge after harvesting, and collection times of 4-5 times during the growth period are approximately mid-May to mid-June each year. To pick no insects, no frost to fight rough and fresh. It is best to squat under 20 cm and place it in the basket. Do not use bags. Do not bruise and avoid the sun. The harvested Osmunda must be sorted, coarsely and finely divided, removed from the aging part, and smashed and velvety hair (also can be boiled after boiling the pan).
