Scirpus is a genus of aquatic, grass-like species in the family Cyperaceae (the sedges), many with the common names club-rush or bulrush (see also bulrush for other plant genera so-named). Other common names are deergrass or grassweed. They have grass-like leaves, and clusters of small spikelets, often brown. Some species (e.g. S. lacustris) can reach a height of 3 m, while others (e.g. S. supinus) are much smaller, only reaching 20–30 cm tall.
Method for breeding nutrient bulb of scirpus planiculmis based on hydrologic regulation
The application relates to a method for breeding Scirpus planiculmis nutrient bulb based on hydrological regulation, and relates to a breeding method for Scirpus planiculmis nutrient bulb. The method is used to solve the problems of high cost and strong uncertainty in the existing Scirpus planiculmis bulb breeding process. The method comprises the following steps: S1, seed source collection and screening; S2, culture medium and container screening and preparation; S3, Scirpus planiculmis bulb sowing control; S4, stage hydrological regulation; and S5, Scirpus planiculmis bulb harvesting. The application sets up differential water level management based on different growth and development stages of Scirpus planiculmis, can significantly improve the quantity and quality of Scirpus planiculmis bulb breeding, and realizes bulb large-scale proliferation. The application adopts a 26cm-diameter and 30cm-depth gallon pot to breed Scirpus planiculmis nutrient bulb, about 200 bulbs can be harvested from each pot, the dry weight of the bulbs in each pot is about 360-420g, and the breeding efficiency is stably improved. The application can be used in the fields of laboratory breeding, scientific test and degenerated Scirpus planiculmis wetland ecological restoration.
