Description

Composition for coated soil, coated soil and preparation method of coated soil
Technical Field
The invention relates to a composition for coated soil, coated soil and a preparation method thereof.
Background
In spring, peanuts and potatoes are planted, and a layer of mulching film is covered after sowing to raise the soil temperature, maintain the soil moisture and the soil structure, prevent pests from invading crops and diseases caused by certain microorganisms, and promote plant growth. However, the mulching film is elastic and is difficult to break only by the seeds, so that the mulching film needs to be manually buckled and opened after the seeds emerge, and the seedlings grow smoothly. At present, a high-ridge film soil covering technology is also available, such as a Lanzhou agricultural science and technology research popularization center, a Lanzhou agricultural academy of sciences, a Ulmus and county agricultural technology popularization center, a Lanzhou red ancient region agricultural technology popularization center and a stationary region agricultural comprehensive law enforcement and division team are combined to take out a high-ridge film soil covering technical specification of potatoes in Gansu province, and the mulching film is generally exposed after sowing, so that the ground temperature is quickly increased, germination is promoted, and soil covering is carried out after about 15 days and before one week from emergence. The first earthing is carried out for 1-2 times, and the thickness is not less than 3cm. The covering soil should be uniform in thickness, broken, large soil blocks are forbidden, and the width should be as wide as possible. However, although the thickness of the soil is limited, the inventors have found that the structure and properties of the soil are also critical to the rate of emergence, and that the final rate of emergence is different by covering different soils.
If the covered soil is turfy soil, the emergence rate is still low and is lower than 60% even if the covered soil is thicker; the common soil is adopted, the problem of unstable effect is also caused, the effect is greatly affected by weather, particularly, the problem is greatly related to rainfall in the period of time after soil covering and before emergence, the inventor finds that the natural film breaking rate of the seedlings is very high and can reach more than 90 percent when the period of time after soil covering and before emergence is not rained, but the natural film breaking rate of the seedlings is relatively low and is lower than 70 percent when the period of time after soil covering and before emergence is rained. At present, a method for covering soil after film covering is not available, so that the natural film breaking rate of seedlings is high and the seedlings are not affected by weather, and meanwhile, the method cannot affect the growth of crops.
Disclosure of Invention
The invention provides a composition for coated soil, coated soil and a preparation method thereof, which solve the technical problems that 1) the coated soil prepared by using the composition for coated soil is used for coating the film, so that the natural film breaking rate of seedlings is high and the seedlings are not influenced by weather; 2) The covered soil does not affect the growth of crops.
In order to solve the technical problems, the invention adopts the following technical scheme:
a composition for coated soil comprising a solid amine and titanium dioxide;
the mass ratio of the solid amine to the titanium dioxide is 99-99.8:0.2-1;
the covered soil is soil pressed on a mulching film at the sowing seed position.
The solid amine includes one of octadecylamine, dodecyl amine and dodecyl amine.
The titanium dioxide is one or two of titanium dioxide p-25 and anatase phase nano titanium dioxide.
The preparation method of the composition for the coated soil comprises the steps of respectively packaging solid amine and titanium dioxide to obtain the composition for the coated soil.
The mass ratio of the soil to the composition for the coated soil is 90-98:2-10;
the soil density is2.6～2.8g/cm 3 。
The method for preparing the composition for the coated soil comprises the steps of adding solid amine, titanium dioxide and soil into a pulverizer, and pulverizing to obtain the coated soil.
The mesh number of the covered soil is 1-10 mesh.
The invention has the following beneficial technical effects:
1. according to the method, the density of soil and the mesh number of the tectorial membrane soil are limited, so that the tectorial membrane soil is easier to attach to the tectorial membrane, and the higher natural seedling membrane breaking rate is achieved.
2. According to the application, the soil is modified by adding the solid amine, so that the solid amine is wrapped on the surface of the soil particles to form the cationic membrane, hydrophobic isolation is formed between the soil particles, and even if rainfall is encountered, the soil particles cannot be aggregated, so that the seedlings can break the membrane smoothly.
3. The titanium dioxide is added to degrade the solid amine under the irradiation of ultraviolet light, so that the influence of the solid amine on crops is reduced; this is because the number of soil particles prepared in the present application is 1 to 10 mesh, so that a large amount of solid amine is required to be added in order to completely wrap the soil particles, and because the solid amine is hydrophobic, when the seedlings break the film, the film-covered soil is deposited around the seedlings to form hydrophobic soil, and the film is impermeable around the soil, so that precipitation is not easy to directly permeate into the roots of the seedlings, thereby affecting the growth of plants.
4. According to the method, the solid amine and the titanium dioxide are respectively and independently packaged, because the solid amine is in small grain crystals or sheet crystals, the titanium dioxide is powder, and the densities of the solid amine and the titanium dioxide are different, for example, when the solid amine and the titanium dioxide are packaged in a mixing way, the problem that the solid amine and the titanium dioxide cannot be uniformly mixed and layered exists, and the prepared tectorial membrane soil is unstable in effect.
5. The composition for the tectorial membrane soil is used for preparing the tectorial soil, and is used for the tectorial soil of a membrane, so that the natural membrane breaking rate of seedlings is high, and the seedlings are not affected by weather.

In this application, the water spray is in order to simulate the precipitation condition, because under the condition of not precipitation, even do not change the soil, still have higher rupture rate.
As can be seen from the data of ck and comparative 1 in table 1, the addition of solid amine can significantly improve the membrane rupture rate; as can be seen from comparison of the data of comparative examples 2, 3 and example 1, the density of the soil and the mesh number of the coated soil both affect the natural film breaking rate of the seedlings.
As can be seen from a comparison of the data in Table 1 for comparative example 1 and example 1, although comparative example 1 has a better membrane rupture rate, it affects potato yield.
As can be seen from comparison of the data of the comparative example 4 and the data of the example 1, in the preparation method of the tectorial membrane soil, solid amine, titanium dioxide and soil are added into a pulverizer to be pulverized, so that the natural membrane breaking rate of the potatoes is directly influenced.
