Description

A kind of cultivation method of ornamental tree with extra-long supporting root system

technical field

The invention belongs to the technical field of landscape architecture, and relates to a method for cultivating ornamental trees with extra-long supporting root systems.

Background technique

In the process of tree growth, due to changes in the resource level of the habitat, the adjustment of the biomass distribution relationship between the above-ground part and the underground part and between different organs often occurs, which leads to plastic changes in tree morphology. In the process of cultivating garden trees, sometimes in order to adapt to the appreciation needs of tourists, or to increase the interest and ornamental value of the garden landscape, it is necessary to orientate the shape of the trees. This requires in-depth understanding and mastery of the tree's growth response laws on the basis of directional cultivation according to the situation.

SUMMARY OF THE INVENTION

In order to increase the interest and ornamental nature of garden landscape, the present invention proposes a cultivation method of ornamental trees with extra-long supporting root system, comprising the following steps:

Step 1: Select the target tree with deep rooting, long, thick and strong root system (strong plasticity of the root system means that the morphological structure of the root system can be changed, that is, it can change with the change of environmental conditions), as much as possible. Understand the root growth characteristics of target trees, especially their demand characteristics for soil water, nutrients and light, and their growth response characteristics under different levels of soil water, nutrients and light conditions. In the case of insufficient existing data, experimental research is needed to obtain in-depth data on the characteristics of target trees' demand for soil water, nutrients and light and their growth response characteristics under different levels of soil water, nutrients and light conditions;

The steps and content of the experiment include planting target trees under different levels of soil moisture, nutrients and light conditions, and observing the growth characteristics and morphological structure changes of the target tree roots, especially the root branching ability, root branching ability, and root distribution. The length and thickness of the branches.

Step 2: On the basis of fully understanding the root growth characteristics of target trees, start to cultivate ornamental trees with extra-long supporting root systems. Select healthy seedlings of the target tree, and build a high platform (1) by layering soil at the target site (it is not recommended to choose at the tuyere) to cultivate the target tree. The height of the high platform (1) is determined according to the target requirements for the cultivation of ornamental trees with extra-long supporting root systems and the biological and ecological characteristics of the target trees themselves. The soil layered accumulation of the high platform (1) (the number of soil layers and the depth of each layer need to be determined according to the root growth characteristics of the specific target trees measured in the pre-experiment; the steps and contents of the pre-experiment include setting different layers, For each layer of soil treatment with different depths, plant the target trees in the soil with different treatments, and observe the growth characteristics and morphological changes of the root system of the target tree in the soil treatments with different layers and depths of each layer, especially the root system. Branch capacity, length and thickness of root branches, and test the regularity and stability of root growth. Select the number of soil layers that can grow the most ornamental and extra-long root system and soil treatment settings of different depths for each layer.

The physical and chemical properties of the soil should meet the needs of the target tree growth. In the case of unsatisfactory conditions, such as the lack of soil aeration, water permeability, organic matter content and essential nutrient elements, the missing components in the original soil should be added separately. Such as cinder-like porous coarse particles, sand and gravel-like fine particles, plant particles and essential nutrient elements lacking in the soil, in order to achieve the purpose of increasing soil aeration, water permeability, organic matter content and essential nutrient elements respectively. Healthy seedlings of target trees, initially planted in the topmost soil. Different levels of soil correspond to the location of the root system of the target tree at different stages of growth. The soil corresponding to the growth stage of the seedling should be relatively fertile to promote the rapid growth of the whole seedling. Corresponding to the soil layer at the young tree stage, the nutrients are generally less fertile than the soil at the seedling stage, and there is a gradient from the fertile level to the moderately lower level. Root systems tend to take root downwards in such soils (The optimum physical and chemical properties of each layer of soil should be determined according to the root growth characteristics of the specific target trees measured in the pre-experiment);

The steps and contents of the pre-experiment include setting treatments with different physical and chemical properties for each layer of soil, planting target trees in soils with different treatments, and observing the growth characteristics and morphological changes of root systems of target trees in soils with different treatments. characteristics, especially root branching ability, length and thickness of root branching, and examine the regularity and stability of root growth. Choose the soil treatment setting that will produce the most ornamental, extra-long root system. Step 3: After the target tree grows stably (stable growth means that the roots of the target tree are thick and deep and firmly embedded in the soil, and can grow upright and stable for a long time without any auxiliary support), and the depth of the root system continues to deepen At the same time, gradually withdraw part of the uppermost soil in several times (a small amount each time), and gradually expose the upper root system (the number of times of withdrawing the uppermost soil and the amount of soil each time need to be adjusted according to the root growth characteristics of the specific target trees. Sure). Losing the upper root system buried in the soil will gradually lose the absorption function of the root system, and the epidermis of this part of the root will gradually evolve into the form of bark, while the lower root system buried in the soil will continue to grow downward to supplement absorption. soil resources needed for growth. Watch the tree grow, master the rhythm, and repeat this step over and over again. It is necessary to ensure that the exposed tree roots grow thick and have sufficient support. Due to the different growth rates of different trees, it is necessary to control the time course according to the previous experimental data and the experience observation during the cultivation process.

Step 4: When the exposed root system of the target tree continues to increase, trees with extra-long supporting root system are gradually formed. After the ornamental effect and the initial design goal are achieved, the roots with smaller diameter can be selectively cut off, and the more ornamental ones can be retained. Roots, and the wounds were treated with tree disinfection methods commonly used in horticulture. After that, routine inspections, observation and maintenance of the growth of trees are required, and it is necessary to ensure that the tree roots remaining in the soil can absorb enough soil moisture and nutrient resources for the growth of trees, and have sufficient supporting capacity and stability. In order to prevent the occurrence of the phenomenon of being blown down by the wind. During strong winds under meteorological semantics, trees with extra-long supporting root systems need to be protected by the auxiliary supporting methods commonly used in horticulture.

The beneficial effects of the present invention are as follows: through the technology of the present invention, trees with extra-long supporting root systems are cultivated, the interest and ornamental nature of garden landscapes are increased, and the dual benefits of ecology and economy are obtained.
