Abstract

The invention discloses an ophiopogon japonicus culture medium suitable for slope greening, which comprises garden soil, an organic fertilizer and a conditioner, wherein the garden soil is conventional garden soil subjected to crushing treatment, the organic fertilizer is a fermented and decomposed compost product, and the conditioner consists of a water-retaining agent, an adhesive and rooting powder. The radix ophiopogonis cultivation medium disclosed by the invention is suitable for side slopes, particularly soil side slopes, especially soil side slopes with small gradient, such as gentle slopes and medium slopes, and rock side slopes in the forms of planting grooves, lattices and the like, and is wide in application range; the culture medium reduces the release speed of nutrients on the whole, reduces the nutrient loss, increases the soil fixing capacity, enhances the growth vigor of plants, is particularly suitable for the growth of the radix ophiopogonis, and has simple operation and low cost.

Description

Radix ophiopogonis cultivation medium suitable for slope greening

Technical Field

The invention belongs to the technical field of slope greening, and particularly relates to a cultivation medium for greening.

Background

The slope greening is a special greening form, is different from conventional garden and forestry greening, is a new slope protection mode capable of effectively protecting bare slope surfaces, is performed by taking the slope as a basis and a carrier, adopting new technology or traditional engineering technical measures and combining with slope protection and effectively realizing ecological vegetation restoration of the slope surfaces to the maximum extent. The side slopes are mainly divided into soil slopes and rock slopes, and can be divided into gentle slopes (the slope is less than 15 degrees), medium slopes (the slope is 15-30 degrees), steep slopes (the slope is 30-60 degrees), abrupt slopes (the slope is 60-90 degrees) and reverse slopes (the slope is more than 90 degrees) according to the slope of the side slopes; the quality of the culture medium on the side slope is a factor directly influencing the growth vigor of the green plants; the traditional culture medium for slope greening is difficult to realize good plant growth, and simultaneously can reduce the rain wash quantity of the culture medium to the maximum extent and increase the soil conservation and soil fixation capacity.

Disclosure of Invention

In order to solve the problems in the prior art, the invention provides an ophiopogon root culture medium suitable for slope greening.

The technical scheme adopted by the invention is as follows: the dwarf lilyturf cultivation medium suitable for slope greening comprises garden soil, an organic fertilizer and a conditioner, wherein the garden soil is conventional garden soil subjected to crushing treatment, the organic fertilizer is a fermented and decomposed compost product, and the conditioner consists of a water-retaining agent, an adhesive and rooting powder.

Further defined, the particle size of the impurities in the conventional rural soil is less than 0.5 cm.

Further limiting, the organic fertilizer is obtained by mixing, fermenting and decomposing one or more of urban domestic sludge, green plant building materials or agricultural straws.

Further limiting, the garden soil, the organic fertilizer and the conditioner are 65-75%, 25-35% and 0.1-2% in sequence by weight percent.

Further defined, the binder in the conditioner is 0.05 to 0.5 weight percent.

The invention has the beneficial effects that: the radix ophiopogonis cultivation medium disclosed by the invention is suitable for side slopes, particularly soil side slopes, especially soil side slopes with small gradient, such as gentle slopes and medium slopes, and rock side slopes in the forms of planting grooves, lattices and the like, and is wide in application range; the culture medium reduces the release speed of nutrients on the whole, reduces the nutrient loss, increases the soil fixing capacity, enhances the growth vigor of plants, is particularly suitable for the growth of the radix ophiopogonis, and has simple operation and low cost.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention are described in detail and completely, and it is obvious that the described embodiments are a part of the embodiments of the present invention, but not all of the embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It will be understood by those skilled in the art that, unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the prior art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

Others in the following examples refer to mixtures of water-retaining agents and rooting powder.

Example 1

The dwarf lilyturf root culture medium suitable for slope greening is prepared by mixing the following components in percentage by weight as shown in table 1:

TABLE 1

Example 2

The dwarf lilyturf root culture medium suitable for slope greening is prepared by mixing the following components in percentage by weight as shown in table 2:

TABLE 2

Example 3

The dwarf lilyturf root culture medium suitable for slope greening is prepared by mixing the following components in percentage by weight as shown in Table 3:

TABLE 3

Example 4

For a better understanding of the present invention, the beneficial effects of the culture substrate are illustrated below by the experiments of the present invention, which are intended to illustrate the role of the culture substrate and not to limit the present patent.

The growth of Ophiopogon japonicus after 1 month comparing the quality of the culture medium shown in examples 1-3 with that of the conventional culture medium is shown in Table 4, CK is English abbreviation of the conventional culture medium,

TABLE 4 comparison table of growth of Ophiopogon japonicus

Example 5

In order to better understand the present invention, the beneficial effects of the present culture medium are further illustrated by the following experiments of the present invention, which are intended to further illustrate the effects of the culture medium and not to limit the present patent.

CK of the same mass, example 1, example 2, example 3, was evenly laid on a custom slope with a slope of 30 ° and rainfall was simulated for 30 minutes. The soil fixing capacity of the culture medium and the conventional culture medium is determined, and the comparison result is shown in table 5:

TABLE 5 comparison table of soil-fixing ability of cultivation substrate

Item	Mass g of substrate scour	The ratio of the amount of the activated carbon to the amount of CK increases
			CK (conventional cultivation substrate)	92.33	-
Example 1	68.87	25.4％
			Example 2	50.30	45.5％
Example 3	56.64	38.7％

And (4) conclusion: as can be seen from tables 4 and 5, after the Ophiopogon japonicus grows for 1 month, the growth condition of the Ophiopogon japonicus planted in the culture medium of the embodiment 1-3 is obviously superior to CK (conventional culture medium), and the plant height and fresh weight of the plant are obviously superior to those of the CK group; meanwhile, the soil fixing capacity of the culture medium in the embodiment 1-3 is obviously higher than that of the CK group, which shows that the culture medium disclosed by the invention is suitable for the growth of the side slope radix ophiopogonis, is favorable for protecting the side slope and reduces the side slope soil loss.
