Cultivation matrix for planting passion fruits through improving coral sand of filled island reef

Abstract

The invention relates to a cultivation matrix for planting passion fruits through improving coral sand of a filled island reef and belongs to the technical field of fruit tree growing. The cultivationmatrix is prepared from the following ingredients in volume ratio: peat, sheep dung and the coral sand which are in the volume ratio of (2 to 3): (0 to 2): (1 to 2). By adding the peat and the sheepdung, the alkaline strength, porosity and salt content of the coral sand are lowered, the nutrient content of the coral sand is improved, the moisture-retaining powder is enhanced, bottommost soil conditions for planting the passion fruits are achieved, and the requirements of passion fruit seedlings on normal growth and development are met; and the content of organic carbon in the cultivation matrix is further increased, fast-acting K and P are further increased, the display of growth effect is better, and indexes such as survival rate, maximum branch length, total branch amount, flower amount and set fruit amount are higher than average values.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a cultivation substrate for passion fruit cultivation improved by filling island reef coral sand. Background technique [0002] Passion fruit, also known as passion fruit and egg fruit, is a vine fruit tree of the genus Passiflora in the Passiflora family. Native to southern Brazil, tropical and subtropical regions; unique leaf shape, bright flowers, evergreen all year round, oval-shaped berries, single fruit weight 60-120g, orange juice, moderate sweet and sour, unique flavor, high nutritional value; can be used It is processed into fruit juice, fruit dew, jam, jelly, and candied fruit; the peel can be used as feed and pectin extraction, and the roots, stems, and leaves can be used as medicine, which has the effects of anti-inflammatory and pain relief, promoting blood circulation and strengthening the body, nourishing yin and kidney, and reducing fat and blood pr...

AI Technical Summary

Problems solved by technology

However, due to the strong alkalinity, high salt content, large porosity, weak water holding capacity and low organic matter content of coral sand, as the planting soil of passion fruit, it cannot meet the normal growth and development of passion fruit seedlings. The principle of improving the soil quality of coral sand is the key factor for the successful cultivation of passion fruit
