Embodiment 1

[0130] Investigate the tolerance of three species of Tribulus terrestris, Imperata ipteratum and Guojiangteng to the salinity in the planting soil.

[0131] Under the same planting environmental conditions and the same planting soil quality (sand:soil = 1:1), Tribulus terrestris, Imperata Imperata, and vine were planted respectively, and then the plants were watered with seawater of different salinities, and observed 30 days after planting The survival conditions of each plant, specific parameters and test results are shown in Table 1 below:

[0132] Table 1

[0133]

[0134]

[0135] From the above test results, it can be known that Guojiangteng can survive completely under the condition of planting soil salinity of 1‰~7‰. When the salinity continues to increase, the survival rate decreases significantly. When the planting soil salinity exceeds 9‰, the survival rate is only 66%; Tribulus terrestris can survive completely under the condition of planting soil salinity of...

Embodiment 2

[0137] To explore the effect of planting soil quality on the survival rate of three species of Tribulus terrestris, Imperata ipteratum and G.

[0138] Under the same planting environmental conditions and the same planting soil salinity (5‰), Tribulus terrestris, Imperata ipteratum, and vine were planted respectively, and the proportion of sandy soil and red loam in the planting soil was used as a variable to observe the survival of each plant after 50 days of planting. The situation, specific parameters and test results are shown in Table 2 below:

[0139] Table 2

[0140]

[0141]

[0142] As can be seen from the above test results, the embodiment of the present invention has a high survival rate in sand: the mass ratio of red soil is (1 ~ 4): 1; The survival rate is high in the soil quality; the survival rate of Imperata coronata is high in the soil quality ratio of sand:red soil (1~2):(1~4).

Embodiment 3

[0144] as attached figure 1 Shown, a kind of construction method of the flora of coastal beach comprises the following steps:

[0145] ① First determine the elevation and range of the planting site, check the tide table of the State Oceanic Administration, find the tide table of the nearest marine monitoring station, calculate the local average high tide level value, and measure the elevation of the average high tide level on site as the minimum planting The lower limit line of the range, and then rises to the coast, and the line of the upper limit of the coast is determined by the height of the coast. According to the slope from the lower limit line to the upper limit line, the slope gradually rises slowly, and the site is leveled.

[0146] ②The first planting area (D area) is one-third of the planting area, planting Imperata and vines, the spacing between plants and rows is 0.3 m x 0.3 m, first adopt the rhizome propagation method to plant Imperata, 15 days later Imperata s...

Abstract

The invention belongs to the technical field of the ecological restoration of coasts, and particularly relates to a construction method for a costal plant community. The construction method comprisesthe following steps of: taking a local average high tide position as a plantation lower limit line, and taking a coastline position as a plantation upper limit line; in a plantation area, taking an area which is near 20-40% of the plantation lower limit line as a first plantation area, taking an area which is near 20-40% of the plantation upper limit line as a third plantation area, and taking anarea between the first plantation area and the third plantation area as a second plantation area; in the first plantation area, planning imperata cylindrica (L.) Beauv. and Phyla nodiflora (L.) Greenein sequence; in the second plantation area, planting Tribulus terrestris L. and the imperata cylindrica (L.) Beauv. in sequence; and in the third plantation area, planting the Tribulus terrestris L.,the the imperata cylindrica (L.) Beauv. and the Phyla nodiflora (L.) Greene in sequence; and maintaining to form the plant community. The construction method for the costal plant community, factors,including seawater flooding frequency and time, plant characteristics and the like, are integrated to carry out reasonable combination and configuration, and therefore, a layered and stable coast prevention ecological chain with plant diversity is formed.

Description

technical field [0001] The invention belongs to the technical field of coastal ecological restoration, and in particular relates to a coastal plant community and a method for constructing a coastal plant community. Background technique [0002] Tropical and subtropical coastal reefs and coastal beaches are hit by wind and waves all the year round, the stability of substrate conditions and water retention are poor, and there are extremely harsh environmental characteristics such as high salinity, high humidity, poor soil, and frequent typhoons. It is difficult for plants to grow and difficult to grow. Form a stable, long-lasting plant community. It is one of the current research hotspots to build a coastal reef and beach ecological protection system as soon as possible, restore plant communities, and play corresponding functions such as windbreak, sand fixation, and bank revetment. When planting plants on coastal reefs and beaches, the plants are first affected by the salini...
