Embodiment 1

[0019] like figure 1 As shown, a cultivation substrate for eliminating salinization of indoor planting soil according to the present invention includes: gravel layer 1, non-woven fabric layer 2, weathered granite layer 3 and organic matter layer 4. Wherein, the crushed stone layer 1 is placed at the bottom of the cultivation bed, and a non-woven fabric layer 2 is laid on it. A weathered granite layer 3 is placed on the non-woven fabric layer 2. After the plants take root, an organic matter layer 4 is added on the weathered granite layer 3 .

[0020] Taking the indoor cultivation of rhododendron as an example, place crushed stones at the bottom of the cultivation bed with a layer thickness of 1000mm to form a crushed stone layer 1, and lay a non-woven fabric with a thickness of 20mm on the crushed stone layer 1 to completely cover the surface of the crushed stone layer to form a non-woven fabric layer 2. Then fill the non-woven fabric 2 with decomposed granite with a thickness ...

Embodiment 2

[0026] The cultivation substrate for eliminating salinization of indoor planting soil according to the present invention has been applied in the soil of Greenhouse A of Chenshan Botanical Garden, wherein Greenhouse B is used as a control example, and a conventional greenhouse soil cultivation method is adopted.

[0027] In greenhouse A, gravels of 20-30 mm are placed at the bottom of the cultivation bed, with a layer thickness of 1200 mm to form a gravel layer 1, and a non-woven fabric with a thickness of 15 mm is laid on the gravel layer 1 to completely cover the surface of the gravel layer to form a non-woven fabric. The cloth layer 2, and then fill the non-woven fabric layer 2 with decomposed granite with a thickness of 2000mm to form the granite layer 3. Then the plant seedlings are planted in the weathered granite layer 3, and the water will be poured enough and drenched. Thereafter, depending on the dry and wet conditions of the weathered granite layer, replenish water i...

Abstract

The invention discloses a cultivation matrix for eliminating salinization of indoor planting soil, which comprises a gravel layer, a non-woven fabric layer, a weathered granite layer and an organic substance layer, and is characterized in that: gravels are paved on the bottom part of a cultivation bed to form the gravel layer which favors the drainage of plants, plays a role in eliminating capillaries and can prevent the increase of salt content; then non-woven fabric is paved on the gravel layer to form the non-woven fabric layer which is used for preventing the downward penetration of weathered granite and for controlling the plant roots to grown on the upper part of a cultivation matrix carrying platform; weathered granite is paved on the non-woven fabric layer to form the weathered granite layer; and finally after the plants are rooted, the organic substance layer is added above the weathered granite layer. The upper part of the cultivation matrix carries the planting matrix and roots of the plants, the middle part of the cultivation matrix is provided with the non-woven fabric, and the lower part holds the gravels, so the salinization phenomenon of the indoor planting soil can be effectively eliminated.

Description

technical field [0001] The invention relates to the technical field of woody plant cultivation, in particular to a cultivation substrate for eliminating salinization of indoor planting soil. Background technique [0002] The traditional way of cultivating woody plants indoors is to plant the plants in containers. As the plants grow, the root system becomes denser, and the planting soil becomes salinized, which seriously affects the growth and landscape effects of woody plants. [0003] The salinization of indoor planting soil is due to the fact that the indoor planting soil is covered by a certain shelter, so that the natural rainwater cannot irrigate the indoor planting soil, so that the leaching of rainwater cannot occur. At the same time, because of the cover of the shelter, when the plants are transpiring, the rise of inorganic salts to the surface soil is accelerated, and the salts are enriched. The concentration of inorganic salts in the planting soil is higher than th...
