1\ Seedling mound propagation In Shandong Province, when the height of reed seedlings is more than 3 cm from mid-May to early July, reed seedlings with stout stems and 2-4 tillers are selected from the high-yield reed beach, and the periphery of the seedlings are cut with a shovel, and square seedling mounds with a width of about 2-25 cm and a depth of 2 cm are dug out, and the reeds are planted in the beach with a row spacing of 1-1. Then keep your feet firmly around, and then keep shallow water of 1 ~ 15 cm, with the maximum not exceeding 33 cm, so as to facilitate the survival of hairy roots < P > 2. After the soil is thawed in spring, the ramets on the rhizomes begin to germinate. At this time, excellent rhizomes can be selected for propagation. Choose dark yellow to brown, with thick stem walls, in which the overground stems are thick and firm, the rhizome is 3-5 cm long, with more than 5 nodes, and each node has obvious lateral buds and many branched branches, and antlers are preferred. After selecting according to the above standards, cut off branches with branches 3-5 cm thick, and insert them into the soft mud one by one with iron forks according to the row spacing of about 1 meter. Before and after the sprouts are unearthed, the soil surface should always be kept moist or shallow water
3\ Green pressing method is used for breeding. In July and August when there are many rainy days, green reeds with strong growth are selected, cut from the surface, and the culms are 2 ~ 2.5 meters high, and the tender shoots are removed by 5 cm. Turn up the beach with a plow, put the green reeds with the tips removed into the furrows one by one, and cover the soil to keep the ground moist or shallow water. (in the pre-growth period when the annual average temperature is 18℃-35℃, take the thick reed stems of that year as seedlings, cut them from the roots, and select those with a height of more than 5 cm. Then fill the leveled land with water, and the water layer is about 5-1 cm. Then, the lower part of the adopted seedling is laid flat in the soil for more than 5-1 cm, and at least one leaf node is inserted into the soil, so that the upper part of the reed is exposed out of the water. The planting spacing is 3-5 cm, and the planting density is 5-6, seedlings per mu. The cultivation technique of the invention has the advantages that the cultivation method is simple, the survival rate is as high as 98% after strengthened management, the planting cost is greatly reduced, and the quality of new reed is good, the yield is high, and the soil quality requirement is low, so that it can be cultivated in barren beaches and wetlands with high salinity, which is of great significance for improving the ecological environment, improving vegetation protection and environmental protection, and increasing people's demand for reed resources. )
