Composition for film-covered soil, film-covered soil and preparation method of film-covered soil

Abstract

The invention relates to a composition for mulched soil, the mulched soil and a preparation method thereof, and the composition for the mulched soil is characterized in that the composition comprises solid amine and titanium dioxide, and the mulched soil prepared by the invention can improve the emergence rate of plants and does not affect the growth of the plants.

Description

technical field [0001] The invention relates to a composition for mulching soil, a mulching soil and a preparation method thereof. Background technique [0002] Spring sowing peanuts and potatoes are usually covered with a layer of plastic film after sowing to increase soil temperature, maintain soil moisture, maintain soil structure, prevent pests from attacking crops and diseases caused by certain microorganisms, etc., and promote plant growth. However, since the plastic film is elastic, it is difficult to break open only by the seeds themselves, so it is necessary to manually open the plastic film after the seeds emerge, so that the seedlings can grow smoothly. At present, there are also soil covering technologies on high-ridge film, such as Lanzhou Agricultural Science and Technology Research and Promotion Center, Lanzhou Academy of Agricultural Sciences, Yuzhong County Agricultural Technology Promotion Center, Lanzhou Honggu District Agricultural Technology Promotion Ce...

AI Technical Summary

Problems solved by technology

However, although the thickness of the soil is limited, the inventor found that the structure and properties of the soil are also the key to affecting the emergence rate. Different soils cover different final emergence rates.

[0003] If the covering soil is peat soil, even if the covering soil is thicker, the emergence rate is still very low, less than 60%; while using ordinary soil, it also has the problem of unstable effect, which is greatly affected by the weather, especially when it is related to the covering soil and seedling emergence. The rainfall during the previous period has a lot to do with it. The inventors found that there was no rain during the period after the soil covering and before the emergence of the seedlings, and the natural membrane rupture rate of the seedlings was very high, which could reach more than 90%. When it rains, the natural membrane rupture rate of seedlings is relatively low, less than 70%.

At present, there is no method that can solve the problem of covering soil after mulching, which can make the seedlings have a high natural membrane rupture rate and is not affected by the weather. At the same time, this method cannot affect the growth of crops.
