Abstract

The invention relates to the technical field of ecological engineering, and discloses a planting method for recovering a natural scirpus mariqueter population. The method comprises the following steps of pretreatment of a planting area, wherein the planting area is ploughed, and the terrain drop height is smaller than 5 cm after ploughing; germination accelerating of scirpus mariqueter seeds, wherein the scirpus mariqueter seeds are pretreated through cold storage for a period time and then placed under appropriate conditions for germination accelerating and germination; planting of scirpus mariqueter, wherein the germinated scirpus mariqueter seeds are sown in the pretreated planting area; water level control and later-period management in the planting area, wherein the water level should not be higher than 1 cm when the germinated scirpus mariqueter seeds are sown, should not be higher than 5 cm when the height of scirpus mariqueter seedlings is 10-15 cm and should not be higher than 10 cm when the height of the scirpus mariqueter seedlings is larger than 20 cm, the flooding time should not be longer than 2 days, the total proportion of weeds should not be higher than 0.1%, and spartina alterniflora plants need to be removed in time. According to the planting method, by planting the aboriginal plants-scirpus mariqueter, the structure and the functions of a salt marsh ecosystem are recovered, and the biodiversity of a salt marsh is improved.

Description

technical field [0001] The invention relates to the technical field of ecological engineering, in particular to a planting method for recovering the natural populations of the sea clovergrass. Background technique [0002] Scirpus×mariqueter is a perennial herbaceous plant of the Cyperaceae Scirpus genus. It is an indigenous species and a key species in the wetland ecosystem of Chongming Dongtan in Shanghai and even the entire Yangtze River estuary. Once it disappears, the ecosystem will be destroyed. will crash. Sea trigonum is also endemic to my country. It is mainly distributed in the Yangtze River estuary and Hangzhou Bay. It is a pioneer plant on the original bare land in the tidal intertidal zone and plays a very important role in the wetland ecosystem of the Yangtze River estuary. Sea trigonum can form a large single-species community stretching tens of kilometers in the intertidal zone of the estuary, which has the functions of wave dissipation, beach protection, an...
