Abstract

The invention discloses a high water-storage matrix applicable to a tropical island, and belongs to the technical field of plant cultivating matrixes. The high water-storage matrix is composed of a component A and a component B, and is prepared by uniformly mixing the component A and the component B with the volume ratio being 0.7:1-1:0.7 at the normal temperature; the component A is desalted seawater, and the component B is composed of, by volume, 45-50% of laterite, 5-8% of paper scraps, 40-45% of green plant humus, 1-2% of humic fertilizer, and 0.03-0.08% of aggregating agent. The artificial soil matrix is small in volume weight, the volume weight reaches 0.5-1.2 g / cm<3>, the porosity is high and reaches 40-60%, the high water-storage matrix has ideal water-absorption and water-storage functions, the maximum water-holding capacity is larger than 100%, and thus the dependence of the island on fresh water and soil can be sharply reduced; through the adoption of the artificial soil matrix, the purposes of ecological restoration and vegetable cultivation can be achieved by merely relying on natural rainfall.

Description

technical field [0001] The invention belongs to the technical field of plant planting substrates, in particular to a high water storage substrate suitable for tropical islands and reefs. Background technique [0002] The climate of tropical islands and reefs is a typical tropical marine monsoon climate, characterized by high temperature and high humidity, abundant rainfall, frequent strong winds, strong radiation and abundant heat. There is no obvious seasonal division of rainfall on tropical islands and reefs. It is the rainy season all year round, and the main form of rainfall is showers. The main form of showers is thundershowers. Although the rainfall in the island and reef sea area is so abundant, the temporal and spatial distribution is not balanced. The rainfall varies with the seasons: less in the transitional season and more in the second half of the year; the rainfall is less in the west and north of the Nansha Sea area, and more in the east and south.
