Method for constructing close-to-nature vegetations in southern coastal sandy land

Abstract

The invention discloses a method for constructing close-to-nature vegetations in a southern coastal sandy land. The method disclosed by the invention comprises the following steps: firstly, screening six plants, namely lpomoea pes-caprae, scaevola taccada, spinifex, vitex rotundifolia, catharanthus roseus and stachytarpheta jamaicensis, which are suitable for planting in the coastal sandy land, and forming two combinatorial planting; then, digging planting holes, adding family manure as a base fertilizer, adding a water-retaining agent, placing straws on the peripheries of the planting holes to form straw checkboards (which have the function of improving the microenvironment (light shading, wind keepout and the like) for seedling growth, and the straws can be used as a fertilizer after being rotted), soaking bag seedlings with water, adding a compound fertilizer, backfilling sand or foreign soil, and maintaining. After about two months, the six plants are relatively good in growth effect and can form the close-to-nature vegetations; in addition, the vegetations are relatively simple to manage and maintain, and the survival rate reaches over 90 percent respectively.

Description

Technical field: [0001] The invention belongs to the field of vegetation restoration in coastal sandy land, and in particular relates to a method for building near-natural vegetation in southern coastal sandy land. Background technique: [0002] Coastal sandy land is equivalent to an extremely degraded ecosystem, with extremely poor soil or matrix conditions (lack of soil and organic matter, poor stability and water retention), and facing harsh conditions such as high temperature, high salinity, strong light, multiple typhoons, and obvious alternation of rain and drought. Under climatic and environmental conditions, it is usually difficult for plants to survive and settle, and it is extremely difficult to establish (or restore) vegetation. As the development of the coastal sandy land is intensified, many places are faced with the work of building new vegetation in the coastal sandy land for sand fixation, greening and improving the ecological environment. However, revegetat...
