Problems solved by technology

[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

Embodiment 1

[0019] Location: In a southern coastal sandy land:

[0020] 1. Plant species: 6 kinds of plants including Athenaeum, Pittosporum, Hyena, Vitex unileaf, Periwinkle and false horsewhip.

[0021] 2. In terms of planting space, start by planting 2 rows of thick vines near the seaside, and then plant Pittosporum or Hyena inward after the 2 rows of thick vines, and then plant Vitex unileaf, periwinkle and false horsewhip together Embellish it.

[0022] 3. Digging holes and putting base fertilizer: The planting method is to dig planting holes first. The planting holes are conical, the diameter of the conical surface is 30cm, the height is 30cm, the distance between seedlings is about 30cm×30cm, and the height of seedlings is about 15cm and above. Put farmhouse basal manure (the amount is 2 / 3 the volume of the nutrient bag of planted plant bag seedlings) in the hole, and then put water retaining agent 5g / plant.

[0023] 4. Lay straw grid: Put a layer of straw about 1cm thick along t...

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...
