specific Embodiment approach 1
[0019] Specific embodiment one: present embodiment is a kind of reed seedling optimal transplanting density and the acquisition method of initial planting height, specifically is finished according to the following steps:
[0020] 1. Collection of reed rhizomes in the wild: In late April, dig out rhizomes through small patches, dig up to the extension of horizontal rhizomes, dig out rhizomes, put them into black plastic bags, and Spray water to keep the surface of the rhizome moist to obtain the rhizome to be raised;
[0021] 2. Indoor seedling cultivation: wash and remove the soil on the surface of the rhizomes to be raised, and then spread it on the surface of the sand. The depth of the sand is 48cm to 52cm. Then use river sand to cover and bury the rhizomes to be raised, and spray water until the water content of the sand reaches 85% to 100%, and then grow seedlings at an indoor temperature of 25±3°C;
[0022] 3. Seedling cultivation: 4 seedling height gradients are set wi...
specific Embodiment approach 2
[0025] Embodiment 2: The difference between this embodiment and Embodiment 1 is: in step 1, the rhizomes are excavated through small plaques, and the rhizomes are excavated at a depth of 20 cm to 30 cm. Others are the same as the first embodiment.
specific Embodiment approach 3
[0026] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: in step 2, river sand is used to cover and bury the rhizomes to be raised, and the thickness of river sand covering is 2cm. Others are the same as those in Embodiment 1 or 2.
