Embodiment 1

[0027] Example 1: Optimization of artificial cultivation conditions and technical construction of algal crusts in typical tropical coral reef environments in the South China Sea

[0028] The present invention can ensure that the reef algae crust seed soil derived from typical tropical coral islands in the South China Sea can be used in different concentrations of carbon sources, nitrogen sources, phosphorus sources, and potassium, magnesium and iron elements under the simulated natural environment of South China Sea islands and reefs. Compared and combined with the optimal inoculum amount to cultivate the method of artificially cultivating algae crusts to obtain high biomass in the room. The specific operation is carried out according to the following steps:

[0029] 1. Consider the 7 factors of inoculum size, glucose, sodium nitrate, disodium hydrogen phosphate, potassium chloride, magnesium chloride and ferrous chloride, set 4 levels for each factor, and then use the seven-f...

Embodiment 2

[0040] Example 2: Indoor inspection of the effect of the artificial cultivation technology of algae crusts on tropical coral islands and reefs in the South China Sea

[0041] During the experiment, the biomass of the algal crust samples was measured at the beginning and end of the experiment, respectively. The specific measurement method is:

[0042] 1) Put it into a freeze dryer to remove moisture (48h) before measuring;

[0043] 2) Take out the crust, remove loose sand grains, and record the thickness of the crust with a vernier caliper (unified thickness standard, about 0.1cm), then grind with a mortar in the dark to separate the algae from the sand grains, and disperse algae;

[0044] 3) Weigh 2g (±0.02g) samples respectively and put them in a stoppered scale test tube, and use acetone extraction to measure the content of chlorophyll a (expressed by the content of chlorophyll a per gram of dry crust soil sample), set 3 repetitions ;

[0045] 4) Add 10 mL of 80% acetone...

Embodiment 3

[0050] Example 3: Field inspection of the effect of the artificial cultivation technology of algae crusts on tropical coral islands and reefs in the South China Sea

[0051] The algae crusts artificially cultivated by the method of combination 3 in Example 1, and the fresh samples of algae crusts collected in tropical coral islands and reefs in the South China Sea were made into seed soil respectively, and the two were inoculated into the environment of tropical coral islands and reefs to carry out artificial Test of the adaptability of cultivated algal crusts in the field. The specific operation method is as follows:

[0052] 1) Using a soil grinder, the algal crusts cultivated in the laboratory and the collected fresh algal crusts were evenly crushed to make three types of crust seed soils, namely: artificial algal crust seed soil, in-situ Fresh algae crust seed soil and mixed seed soil evenly mixed in a ratio of 1:1;

[0053] 2) Inoculate the three types of seed soil even...

Abstract

The invention discloses a phycomycete crust cultivation method suitable for calcareous sand soil of a South China Sea coral island reef. According to the phycomycete crust cultivation method suitable for the calcareous sand soil of the South China Sea coral island reef, an in-situ phycomycete crust is directly propagated and domesticated, and the cultivated phycomycete crust is directly inoculated in the field, so that the separation and purification process is omitted, the culture speed is high, the material consumption is reduced, the field adaptive capacity of the artificially cultivated phycomycete crust is improved, and the phycomycete crust cultivation method has an important application value for ecological system restoration of the South China Sea coral island reef.

Description

technical field [0001] The invention belongs to the technical field of artificial cultivation of algae crusts on calcareous sandy soil, and in particular relates to a method for cultivating algae crusts suitable for calcareous sandy soil on coral reefs in the South China Sea. Background technique [0002] Biological soil crusts (biological crusts) are microscopic soil particles that are destroyed by bacteria, cyanobacteria, diatoms or green algae, tiny Fungi, lichens, and bryophytes, as well as non-vascular plant constituents common in many landscapes, use mycelium, rhizoids, and exudates to "cement" complex complexes. The role and function of biological crusts in desert ecosystems, such as the ecological functions displayed by soil ecological processes, biogeochemical cycle processes, ecological processes, and hydrological processes, have gradually been widely recognized in recent years. It has been specifically applied in the practice of desert ecological restoration. Al...
