Description

Vegetation type ecological concrete miniature plant cultivation method

technical field

The invention relates to a method for cultivating miniature plants on vegetation-type ecological concrete, which belongs to the technical field of green buildings.

Background technique

With the development of economy and the rapid growth of urban population in our country, urban buildings are becoming more and more dense, and people have realized the importance and urgency of urban ecological environment construction. Urban plants are an important component of urban ecosystems and an important factor in maintaining urban ecological balance.

Ecological concrete is a kind of special concrete with special structure and surface characteristics, which can reduce environmental load, coordinate with ecological environment, and contribute to environmental protection. Vegetation-type ecological concrete has high water permeability, high air permeability and safety. The porosity of vegetation-type ecological concrete is often as high as 40%, and the surface equivalent pore diameter is 2-3 cm. In seasonally cold regions, it is beneficial to eliminate and reduce the water content in the protected soil and reduce freezing damage. The anchoring effect of the grass roots on the vegetation-type ecological concrete can make the retaining masonry safer.

The habitat characteristics of vegetation-type ecological concrete are high calcium, high pH, and water and nutrient limitations. Therefore, the types of plants that can grow on vegetation-type ecological concrete are limited. Now the common plants that grow on ecological concrete are grasses. plant. Woody plants that can directly grow on ecological concrete have not been reported yet. If woody plants can be cultivated on the vegetation-type ecological concrete, the problem of lack of plant species that can be planted on the vegetation-type ecological concrete will be solved, and the plant diversity of green buildings will be increased.

Due to the small seeds of gramineous plants, tiny seeds can be directly sown in the pores of ecological concrete, while the seeds of common woody plants are relatively large, so it is difficult to directly sow seeds into the pores of vegetation-type ecological concrete. Therefore, it is necessary to create a suitable environment for plant seeds to germinate and grow on the vegetation-type ecological concrete, and at the same time provide water and nutrients for plant seeds to maintain growth.

Contents of the invention

The technical problem to be solved by the present invention is to provide a method for cultivating micro-plants on vegetation-type ecological concrete, so as to solve the problem of lack of species of plants cultivated on vegetation-type ecological concrete, and increase the plant diversity of green buildings.

1, the technical scheme of the present invention is: a kind of vegetation type ecological concrete miniature plant cultivation method, comprises the following steps:

The first step: evenly paste mud on the vegetation-type ecological concrete;

Step 2: Collect stone moss in autumn, remove impurities, add water to mash the moss into juice, apply it on the vegetation-type ecological concrete with mud, and then sprinkle water on the concrete to keep it moist, and wait for the moss to grow to form a cluster mat moss-like structures;

Step 3: Sprinkle the seeds into the moss clump formed in step 2, continue to sprinkle water on the concrete to keep it moist, and when the seeds germinate and grow to a plant height of 10-15cm, spray growth regulators to control the height of the plant at 25cm Within this period, the growth regulator is sprayed once every growing season thereafter to keep the plant height within 25cm. the

The stone moss is calabash moss or wall moss.

Vegetation-type ecological concrete is made of 10L perlite, 3.5L cement and 1L fly ash under the pressure of 37.5 KN/ ^m2 according to the conventional ecological concrete production method.

Beneficial effects of the present invention:

Bryophytes epiphytic on bare rocks have developed strong water retention and drought resistance due to long-term evolution. On the one hand, bryophytes cluster or form mats on the rock surface, which can retain seeds. On the other hand, due to their overlapping or cluster growth, the capillary suction between plants is strong, and the water content of the clusters can reach 15% of the dry weight of the plant. -25 times, it can provide moisture conditions for the germination and growth of seeds falling on it; at the same time, because the cluster or mat-like structure of bryophytes can play a role in heat preservation, it can provide the germination and growth of seeds falling on it temperature conditions, and furthermore, the parts of bryophytes close to the ground will rot adaxially, and the clumps or mat-like structures can also trap rainfall and dust, which can provide nutrients for the growth of plants that fall on them. Preliminary cultivation of lithogenic bryophytes on vegetation-type ecological concrete, and then using the "natural hotbed" provided by lithogenic bryophytes for plant seed germination and growth, can achieve the purpose of cultivating plants on vegetation-type ecological concrete.

However, with the growth of plants on vegetation-type ecological concrete, more and more water and nutrients are needed. Relying on the limited nutrients and water provided by the moss attached to the ecological concrete will be difficult to meet the growth of larger plants. Therefore, it is necessary to use growth regulators to control the growth of plants and form micro-plants to achieve the purpose of long-term growth.

1. It can greatly enhance the use value of ecological concrete. At present, most ecological concrete is used for slope protection of railways and highways, embankment protection of rivers, greening transformation of mining areas, etc., and the use of the present invention can not only be used as slope protection, but also can be used for decoration such as roof blocks and exterior wall blocks. The use of greening improves the use value of ecological concrete and makes urban buildings more green and ecological.

2. Increase the diversity of vegetation-type ecological concrete plant species, greatly increase the green area of the city, and improve the ornamental value.

3. The technology is stable and reliable, can guarantee a high survival rate, and has low management costs. At the same time, it can meet the purpose of protecting the diversity of urban vegetation and building an urban ecosystem.

4. It can be used as an indication and forecast of air pollution. The wax-free cuticle on the surface of the moss is covered, and the surface area exposed to the air is large, so that both sides of the moss leaves are directly exposed to pollutants from the air, and can quickly show symptoms of damage to reflect the pollution in the air. Therefore, the present invention can not only maintain the aesthetic appearance of greening concrete, but also provide year-round air detection indication and forecast.
