Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. The examples are given only for illustrating the present invention and are not intended to limit the scope of the present invention. Any obvious modifications or variations can be made to the present invention without departing from the spirit or scope of the present invention.
A soil improvement method for promoting development of peony fine roots comprises the following steps: dividing a soil planting area into a surface layer, a diaphragm layer, a subsurface layer and a deep layer from top to bottom;
surface layer: 30-60cm, original soil: volcanic rock: the ceramsite =4-5:2-3:2-4, the total soil pore and non-capillary pore of the whole proportioning layer are increased by the ceramsite, and the capillary pore of the soil is increased by mixing and permeating the original soil and the volcanic rock.
Membrane layer: the tightly woven geotextile material can not penetrate a large amount of soil, but can be penetrated year by year along with the deep binding of the root system growth
And (2) sublayer: 30cm, volcanic rock: ceramsite =6:3, mainly plays a role in excluding limiting factors in the plant restorative growth stage: the excessive water causes the decay of 3-5 grade thin root systems, causes the dysfunction of the thin root parts of the root systems which mainly absorb water and nutrients, hinders the growth and development of plants such as camellia, peony and the like, reduces the drought and cold resistance and greatly reduces the seed amount in production; along with the rapid growth of the plant root system in different diameter grades and the infiltration of corresponding soil particles, the physical structure of the soil on the layer is slowly changed, the main roots of the plant can extend to the layer, and the fibrous roots, particularly the fine roots, can rapidly circulate to absorb water and nutrients, die and resolve in sufficient time and space to form organic carbon, so that the maximum growth depth (root area space) of the root system can be improved, the rejuvenation capability is improved, and the root system grows and develops again.
Deep layer: the earthen layer connects the subsurface layers and provides support and capillary moisture wicking or seepage.
Comparative analysis
Data for 3 plant species and comparative examples are compared in the following table:
the comparative results in the table above fully illustrate that: the culture soil disclosed by the invention has excellent water retention performance and air permeability, and is suitable for the growth of the fleshy root peony. Compared with the comparative soil volume weight of 1.458, the volume weight of the nutrient soil is obviously reduced, which indicates that the density of the soil is reduced, and the viscosity-weight characteristic of the original soil is improved. Meanwhile, the water holding capacity is obviously higher than that of the comparative example, and the porosity of the capillary also shows that the effective water holding capacity of the soil is greatly improved. Meanwhile, the ventilation degree of the three varieties of peonies is far higher than that of the comparative example adopting the original soil for planting.
The total root system index parameters of the 3 peony varieties and the comparative example are compared as follows:
in the table, the morphological indexes of the total root length, the root surface area, the root volume, the root tip number and the like of the 3 peony varieties are 2-4 times of those of the comparative example,
the root systems of different root sequences have different functions, and directly influence the life span and the landscape degree of plants. Modern researches are mainly carried out according to the traditional root diameter and root sequence method, the fact that the root diameter is less than or equal to 2mm is consistent with the fact that the root is a thin root and mainly plays a role in absorbing water and nutrients, and the root diameter larger than 2mm is a thick root and mainly plays a role in transportation conduction and gravity support. The 5-grade roots which grow at the tail end of the root system and have the thinnest diameter, the shortest service life and the strongest activity show the effect which is obviously higher than that of the comparative example in all the three kinds of peony, and the thin root parts can absorb soil nutrients and water through a large amount of germination and turnover in the nutrient soil of the invention to improve the growth vigor of plants.
As shown in the attached figures 2-4, 5 grades of fine roots of 3 peony varieties and 6 root indexes of comparison are obtained.
The method comprises the steps of carrying out block comparison test design by adopting 3 peony variety plant materials, dividing into 3 blocks, setting a control group, carrying out sampling after 3 years of field planting growth for each block of 30 pots, randomly taking 5 pots in 12 months, dividing and cutting overground stem leaves and underground root systems, cleaning the root systems, scanning the root systems by plants by using an EPSON PERFECTION V700 scanner, analyzing root system parameters by using root analysis software Win RHIO-Pro 2008b (Regent Instruments Inc, canada), counting the root length, the root surface area, the root volume, the average diameter, the branching number and the root tip number of 2 plants, and carrying out classification research on the root systems with complete structures.
Grading root systems: in the laboratory, the root segments of the 3 plant species underground root system samples were placed in a 25cm diameter petri dish containing deionized water and were graded according to the methods described by Pregitzer et al (2002) and Wang Xiangrong et al (2005). The root with the tip at the first end is a 5-grade root, the mother root of the last-grade bifurcation is a 4-grade root, the mother root of the 4-grade root is a 3-grade root, and the like until the root is a 1-grade slender root connected with the stem at the base of the plant.
The above description is only for the specific embodiments of the present disclosure, but the scope of the present disclosure is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present disclosure, and all the changes or substitutions should be covered within the scope of the present disclosure. Therefore, the protection scope of the present disclosure shall be subject to the protection scope of the claims.
