Paving stone for potted plant and preparation method thereof

Technical Field

The invention relates to the technical field of paving stones, in particular to a paving stone for potted plants and a preparation method thereof.

Background

With the improvement of living standard of people, the demands of people on living environment are increased, and especially the green planting plays an important role in modern urban gardening, so that people hope to grow more green planting in indoor and semi-indoor environments such as families, offices and meetings.

In the process of planting potted plants, people feel that the potted plants are available or not due to the fact that people cannot untangle the action of the paving stones of the potted plants and the key points of the paving stones for selection and manufacture, or the phenomenon that the plant grows poorly and even dies is caused by the fact that the paving stones are selected erroneously.

At present, some cobblestones, medical stones, white stones and other materials are selected as paving stones according to traditional experience, but the materials are hard in texture and almost airtight, so that the overall air permeability of the basin soil can be influenced, and the growth of plant roots is influenced. In addition, many people select materials such as ceramsite and diamond-planting stone as paving stones, but the materials are light in texture, and can float or scatter everywhere during watering, so that soil is exposed, or the paving stones are uneven and pothole, and attractive appearance is affected.

Comparative example 1

This comparative example is a preparation method of a paving stone for potted plants, which is substantially the same as that of example 1, except that step (b) is as follows:

spraying water into the soil dust, stirring, mixing uniformly, and granulating to obtain soil granules, wherein the volume ratio of the water spraying amount to the soil dust is 1:10; the particle size of the soil aggregate is 1-2.5 cm.

Comparative example 2

This comparative example is a preparation method of a paving stone for potted plants, which is basically the same as that of example 1, except that sludge from sewage plants is used instead of rice hull chips to form general ceramsite having voids but no plant ash.

Experimental example

1. Paving stones were prepared according to the preparation methods of example 1 and comparative examples 1 to 2, respectively;

respectively selecting paving stones prepared in the example 1 and the comparative examples 1-2, grinding the paving stones into powder with the diameter smaller than 0.01cm, adding water, stirring, fully removing gas, drying at 40 ℃ for 20 hours, calculating the volume of the solidified matters after the solidified matters are completely dried, dividing the volume of the solidified matters by the original volume of the solidified matters, and detecting the porosity of each paving stone, wherein the porosity comprises pores in granules and pores formed among the granules, and the calculation results are shown in the table 1;

20g of the paving stones prepared in the example 1 and the comparative examples 1-2 are respectively selected and respectively placed in 100ml of purified water for soaking for 20 hours; taking out the paving stone, drying, weighing, calculating the reduction rate, wherein the reduction rate is a component (such as potassium carbonate and other salts) which is soluble in water and beneficial to plants in the paving stone, and the calculation result is shown in table 1;

respectively selecting 100 grains of the pavement prepared in the example 1 and the comparative examples 1-2, placing the grains in 0.5L of clear water, counting the number floating on the water surface, and dividing 100 by the number to calculate the floating rate;

TABLE 1

Group of	Porosity (%)	Reduction rate (%)	Float rate (%)
				Example 1	67	1.2	0
Comparative example 1	12	0	0
				Comparative example 2	72	0.2	98

As can be seen from table 1:

although comparative example 2 produced ceramsite with municipal sludge had a larger void space, the floating rate was also very high, and was not suitable for use on potted plant surfaces, while comparative example 1 had a solid ceramsite without any aggregate added thereto, had a very low porosity, and was heavy, and could compact the soil, adversely affecting the air permeability of the soil, while the reduction rate in the examples indicated the presence of water-soluble potassium carbonate and other plant beneficial elements, which slowly entered the soil during watering, and increased the nutrient supplement to the soil.

2. Planting experiment

The planting method, the soil formula (2 parts of garden soil, 1 part of river sand) and the soil quantity are the same; randomly dividing 30 plants into 3 groups, wherein paving stones of the embodiment 1 are paved in each flowerpot of the first group, paving stones of the comparative example 1 are paved in the second group, paving stones of the comparative example 2 are paved in the third group, and paving weights are the same, and the heights are 1.5-2.5 cm high; after planting, watering once a week (42 times in 300 days), wherein three groups do not use any fertilizer and pesticide and bactericide, and do not carry out special management after plant diseases and insect pests occur; after 300 days of plant growth, the plant condition was observed, and the observation results of each group are shown in table 2:

TABLE 2

Group of	Survival after 60 days	Survival after 100 days	Survival after 300 days
				First group of	8	7	7
Second group of	8	6	3
				Third group of	9	6	4

As can be seen from table 2:

the effect of the paving stone is not obvious in a short period, the paving stone adopted by the invention does not show obvious advantages before 100 days, but after long-term jogging for 300 days, the advantages of the paving stone adopted by the invention are gradually shown after different air temperatures change in summer and winter, and the reasons are summarized: 1. the potassium element and other microelements in the plant ash are beneficial to plant growth; 2. the porous paving stones are beneficial to allowing air to enter the soil and also beneficial to volatilizing excessive moisture in the soil and promoting root development; 3. the sterilizing effect of the plant ash reduces the probability of bacteria in the air to spread into soil to a certain extent, and the paving stone containing the plant ash forms an isolation layer.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention, and are intended to be included within the scope of the appended claims and description.
