Embodiment 1

[0051] In the Nansha No. 7 test and demonstration base, the reclaimed coral islands and reefs were cleaned first, pumice and debris on the slope surface were removed, and the wheel loader was used for leveling, a total of 3000m 2 , and then use a small wheeled excavator to dig arbor seedling planting pits. The length, width, and height of the arbor seedling planting pits are 0.5m respectively, and they are arranged in a zigzag shape with a spacing of 1.5m. Before excavation, cables or water pipes buried underground should be avoided. Good drainage measures; dig shrub seedling planting pits in the center of the four adjacent arbor seedling planting pits, the length, width and height of the shrub seedling planting pits are respectively 0.3m, add plant planting substrate in the dug tree and shrub seedling planting pits, The thickness of the planting substrate is 15-20cm; in Wenchang Nursery Base in Hainan, cultivate and screen mangosteen, red thick shell, xushu, and bermudagrass s...

Embodiment 2

[0056] In the Nansha No. 3 test and demonstration base, the reclaimed coral island reef sandy land was cleaned first, the pumice and debris on the slope surface were removed, and the wheel loader was used to level it, a total of 6000m 2 , and then use a small wheeled excavator to dig pits. The length, width, and height of the tree seedling planting pits are 0.5m respectively, arranged in a zigzag shape, and the interval is 1.5m. Before excavation, avoid buried cables or water pipes, and take drainage measures The center of four adjacent tree seedling planting pits digs a shrub seedling planting pit, and the length, width and height of the shrub seedling planting pit are 0.3m respectively, adding plant planting matrix in the dug tree and shrub seedling planting pit, plant planting matrix The thickness is 15-20cm. Cultivate and select seedlings of mangosteen, red thick shell, chrysanthemum, and bermudagrass in the Nursery Base in Wenchang, Hainan, which meet the above requiremen...

Abstract

The invention discloses a method for ecological afforestation on tropical coral reefs and islands, which comprises the following steps: (1) cultivating and selecting seedlings: planting seedlings of cerbera manghas, calophyllum inophyllum and clerodendrum inerme into nonwoven-cloth bags containing culture substrate; the roots and stems of cynodon dactylon are selected and kept wet; all these seedlings are of healthy state; (2) digging planting pits for seedlings: the sand fields of reefs or islands are leveled; planting pits of cerbera manghas seedlings and calophyllum inophyllum seedlings are 0.5m in length, width and height, with 1.5m of spacing from each other, and adjacent planting pits are arranged in a triangular pattern; at the center of every adjacent four planting pits of tree seedling, the planting pits of clerodendrum inerme is dug, with 0.3m in length, width and height; (3) planting the seedlings in the pits. The invention discloses a method for ecological afforestation on southern tropical coral reefs and islands by using indigenous plants. The method is simple, easy, economical, effective and fast when afforesting the man-made reefs and islands.

Description

[0001] Technical field: [0002] The invention belongs to the field of ecological and environmental protection science and technology, and in particular relates to a method for ecological greening of tropical coral islands and reefs. [0003] Background technique: [0004] Tropical coral islands and reefs refer to islands and reefs in the tropical regions of my country, including sea islands and artificially filled sand islands and reefs, which are basically coral reefs. The islands and reefs in the South China Sea are mostly filled with coral reef sand, lack real soil and fertility, and have extreme environmental characteristics such as high salinity, strong alkali, high temperature and strong light. There is almost no plant growth, and it is impossible to form a certain vegetation landscape and corresponding livable environment. In order to build a vegetation ecosystem on dredged reclaimed islands and reefs as soon as possible, play the corresponding functions of windbreak, ...
