Problems solved by technology

The overall dredging and filling uplift is mainly to achieve the purpose of land transformation suitable for forest by raising the planting land in a large area (Pan Lianghao et al., 2012; Lin Wenhuan et al., 2014). Since the planting method of the overall dredging filling and uplifting requires a lot of manpower and material resources, so many Scholars try to raise the local base height

Embodiment 1

[0031] The implementation sample site is in the Bay Mangrove Reserve of Enping Town, Jiangmen City, Guangdong Province. This site is a typical deep-water bare beach with a maximum water level of about 200cm. In March 2018, the Forestry Bureau of Enping City used a total of 1,200 tung trees and olive trees in this experimental site for afforestation, and the survival rate was 0 after 6 months.

[0032] 1. Measurement and prediction of planting ground water level

[0033] A water level gauge (HOBO, U20-001-01 (0-9m), USA) was used to monitor and obtain local water level data for one year. The water level monitoring data are shown in Table 1.

[0034] Firstly, from the one-year water level monitoring data, the month with the largest sum of daily average flooding time at different heights is selected as the water level reference when planting mangroves in this area, which can minimize flooding stress. As shown in Table 1, the sum of the daily average flooding time at different h...

Abstract

The invention discloses a method for planting a mangrove forest in a deep water bare beach. According to the method, the elevation of the beach face is increased in a non-woven fabric bag and bamboo pole combined mode, the survival rate of mangrove plants in the deep water bare beach can be effectively increased, and the survival rates of the aegiceras corniculatum, the radix tinosporae and the acanthopanax trifoliatus planted through the method all reach 50% or above; meanwhile, the method meets the following requirements: a, the method has relatively high stability; b, a certain growth spacecan be provided for the root system of the mangrove plant; c, the material belongs to a natural degradable material, so that unnecessary environmental pollution is avoided; and d, the cost is low, the operation is simple and the popularization is easy. The method not only effectively improves the planting survival rate of the mangrove forest, but also greatly reduces the planting cost, and is suitable for large-area popularization.

Description

technical field [0001] The invention belongs to the technical field of ecology, and in particular relates to a method for planting mangroves on deep-water bare beaches. Background technique [0002] Different mangrove plants have different degrees of tolerance to different tidal water levels (beach elevations). Moderate to low flooding levels are more conducive to the growth of mangrove seedlings. However, if the daily flooding time exceeds a certain threshold, mangroves will Under the stress of prolonged flooding, they cannot survive normally (Chen Luzhen et al., 2006; He Binyuan, 2009; Liao Baowen, 2010). "Technical Regulations for Mangrove Afforestation on Difficult Sites" states that deep-water beaches (deep-water bare beaches) refer to beach sites where the elevation of the beach surface is less than 1.5m below the elevation required for the growth of mangroves. The most common habitat condition that restricts the growth of mangroves is the high water level (too low ti...
