Landscape construction method of tropical psammophyte germplasm resource garden

Abstract

The invention relates to a landscape construction method for a tropical psammophyte germplasm resource garden. The method comprises the following steps of site selection, variety determination and classification, microtopography construction, landscape composition, plant resource collection, plant configuration, planting, non-plant material embellishment, water supply and drainage system and final-period management. The application value of the germplasm resource garden is expanded, and the landscape planning content is enriched. According to the constructed psammophyte germplasm resource landscape garden, on one hand, the science popularization effect of psammophyte resources can be enhanced; secondly, the economic benefit of the germplasm resource garden can be increased under proper conditions, and the scientific value of the garden landscape planning can be enriched; and thirdly, the improvement of landscape value promotes the management of the germplasm resource garden, plays a role in complementing each other, and realizes mutual benefit and win-win situation.

Description

technical field [0001] The invention relates to breeding and horticultural construction, in particular to a landscape construction method for a germplasm resource nursery of tropical psammophytes. Background technique [0002] Psammophytes refer to plants that are native to tropical and subtropical desert regions and have ecological adaptation characteristics such as resistance to wind erosion, sand burial, sunburn, and drought and barrenness. Many psammophytes have developed the characteristics of hypertrophy of stems and leaves, degenerated leaves into spines, and strange flowering and fruiting under harsh habitats. Due to its extensive and peculiar shape and implied indomitable spirit, it is favored in garden applications, resulting in over-exploitation and under-conservation, which seriously damages wild resources. [0003] At present, there are few tropical psammophyte germplasm resource nursery landscape construction methods, and most of the existing garden constructi...

Problems solved by technology

[0004] 1. Single function, resulting in waste or loss of resources

The existing psammophyte germplasm resource gardens are built in full compliance with the standards or methods for collecting plant germplasm resources, without considering the landscape value of psammophyte germplasm resource gardens, and in the construction of psammophyte special gardens , only pay attention to the landscape effect and ignore the value of germplasm resource collection, thus forming a single function of resource garden or psammophyte special garden, resulting in the landscape value of germplasm resource garden not being fully utilized, and resource collection of psammophyte special garden lack of value

Coupled with long-term neglect of management and protection, some important germplasm resources have been lost

[0005] 2. The uniqueness of tropical psammophytes cannot copy the collection or landscape construction methods of other germplasm resources

Tropical psammophytes are plants with ecological adaptation characteristics such as wind erosion resistance, sand burial resistance, sun scorching resistance, and drought and barrenness resistance. They have high requirements for habitats, peculiar plant shapes, and special management methods. Therefore, special techniques are required. technology cannot fully satisfy the
