Problems solved by technology

[0003] CN102619192A discloses a method for improving the elevation of tidal flats to form mangroves suitable for forests. It provides three ways to judge the target elevation by comparing adjacent mangroves, referring to existing literature or field experiment summary, but the survival rate of mangroves is different from that of tidal flats. A number of indicators are closely related, such as mud hardness, mud quality, and insect damage in tidal flats, and are also closely related to the planting conditions of mangroves. Simply relying on raising the elevation still cannot guarantee the survival rate of mangroves

Embodiment 1

[0037] Example 1 Restoration and fixation of muddy mudflats at low tide level

[0038] The test site of the present embodiment is a tidal flat, and the tidal flat with an elevation of 2.0 meters lower than the national 85 is arranged to an elevation of more than 2.0 meters through filling measures. 1. The mud hardness is calculated as the worker's weight is 75kg and the height is 170cm. The depth of the worker's calf is not more than 70cm; and the beach should be maintained with a proper slope (about 10 degrees), and an irregular groove should be reserved every 100 meters. It is convenient for drainage after the ebb tide, and reduces the long-term flooding of autumn eggplant seedlings after the retreat of the dynasty, which affects the growth. Bamboo piles are used on the sea surface, and sandbags + pine or bamboo wood are used for fence construction to prevent soil erosion. The bamboo stakes are 10cm in diameter and 4m long, and one bamboo stake is made every 2-3m. A bamboo...

Embodiment 2

[0039] Example 2 Effects of different elevations, biomass and mud hardness on the preservation rate of mangroves

[0040] The present embodiment, on the basis of Example 1, carries out the planting of autumn eggplant mangroves, and the plan view of the planting method of mangroves is as follows figure 2shown. The area of ​​the tidal flat sample used is 10m×10m, the original planting number is 250 plants, and the planting time is May 2018. Survival rate and barnacle pests, among which the average biomass detection method is to excavate 9 autumn eggplants in the sampling square, drying and weighing, and the detection method of barnacle pests is visual inspection. The detection results are shown in Table 1. On January 12, 2021, after the low temperature, the damage to Nen slightly was investigated.

Embodiment 3

[0046] Example 3 Effects of different mud qualities on the growth and preservation rate of autumn eggplant mangroves

[0047] The ground in this example is a tidal flat in Putuo District, Zhoushan City, Zhejiang Province. Four kinds of muddy planting methods were selected respectively. The elevation of the tidal flat after finishing was 2.2 meters. To investigate the effect of different mud composition on the preservation rate and elevation of autumn eggplant, the results are shown in Table 2. The results show that with the increase of muddy clay content, the preservation rate shows an upward trend. After 1 year, the sandy soil coating surface The sandy soil was seriously eroded, the coating surface decreased, and the clay content increased, which promoted the deposition of the beach surface, and the content of soluble nitrogen and organic matter in clay was higher than that in sandy soil.

Abstract

According to the planting and beach face repairing method for the mangrove plant kandelia candel on the low-tide-level beach, the elevation of the low-tide-level beach is increased through a soil filling measure, the elevation is controlled to be within the range of 2: 00-2.42 m, the ingredients of soil filling mud used for soil filling and the mud hardness of the elevation beach where the soil filling mud is located are controlled, and therefore the survival rate of a kandelia candel mangrove forest is obviously increased; the biological diversity of the mud flat is improved by controlling the planting density of the kandelia candel and the light beach retention proportion, and a certain number of sea birds can be kept, so that the ecological benefits of the kandelia candel mangrove forest are further improved, and beach face restoration of the low-tidal-level muddy mud flat in the northern area of the mangrove forest in China is realized.

Description

technical field [0001] The invention belongs to the technical field of ecological environment protection, and in particular relates to a method for planting and restoring the beach surface of a mangrove plant in low-tidal tidal flats. Background technique [0002] Mangroves play an important and irreplaceable role in preventing wind and waves, fixing embankments and promoting siltation, beautifying the coast, maintaining biodiversity, purifying the sea area, improving the quality of aquatic products, and maintaining the ecological balance of the coastal zone. They are called "coast guards". , "kidney of the earth", has important ecological value. [0003] CN102619192A discloses a method for increasing the elevation of tidal flat to form mangrove suitable forest land, and provides three ways to judge the target elevation by comparing adjacent mangroves, referring to existing literature or summarizing field experiments. A number of indicators are closely related, such as mud ...
