Method for conservation planting begonia plants in water system stream-side ex-situ field and management regulation and control

Abstract

The invention discloses a method for water system stream-side ex-situ conservation planting of begonia plants and management regulation and control, and belongs to the technical field of rare plant conservation. The method comprises the following steps: selecting a place with high humidity at the stream edge of a water system, selecting associated plants of an original habitat, planting arbors, shrubs and herbs in a matched manner, constructing a natural sunshade net by three layers of plants, and creating a shady, cool and humid environment suitable for the growth of begonia plants. A water filtering channel bridge is arranged in the stream direction to purify water. A ground-gripping type planting bowl is arranged, two layers of different matrixes are placed in the bowl, a sowing matrix is placed on the upper layer, a growth matrix is placed on the lower layer, and conditions needed by a sowing period and a growing period are provided respectively. An electric control table is selectively installed under the planting bowl, and the height and the angle can be adjusted through remote control operation. The begonia plants are planted and cultivated in different places from the seeds, so that the wild begonia plants are more effectively domesticated, rare and endangered varieties can be subjected to ex-situ conservation, and a unique garden landscape effect is achieved.

Description

Technical field: [0001] The invention belongs to the technical field of rare plant conservation, and in particular relates to a method for ex-situ conservation and planting of Begonia plants along a river system and a management and regulation method. Background technique: [0002] Begonia (Begonia Linn.) has a wide variety of plants, and both leaves and flowers have ornamental value. These plants have rich and diverse leaf shapes and good landscape effects. Most of them are pink flowers, with clusters of erect inflorescences. Flowers form a beautiful scenery, which is easy to attract the attention of tourists. The illegal collection of wild plants with ornamental or medicinal value has increased in recent years, the rise of online commerce and the logistics industry has made it easier to obtain plant material, and habitats have been severely damaged as human disturbances continue to increase. , the distribution of the population is reduced. As a result, more species may b...

Problems solved by technology

When manually pulling out the surrounding weeds, it was found that the roots of the weeds had grown tightly near the stem-like roots of Begonia plants. Most of the plants in this genus have stem-like roots, which play a role in fixing the plants, and only rely on a small amount of fibrous roots to absorb nutrients. Therefore, , the strength of the two is very different, if no measures are taken, it will be difficult to successfully grow begonias by the stream
