Problems solved by technology

[0004] Organic mulch (plant mulch) is to treat the bare ground, improve the landscape effect and improve soil fertility. It has been popular in Europe and the United States for many years, but because the organic mulch is a product of waste wood crushing, it may be blown away due to strong winds in some areas. result

preparation example Construction

[0039] The preparation method of described matrix material comprises the following steps:

[0040] (1) Preparation of PLGA / ferric oxide mixed solution: add PLGA and tetrahydrofuran to the reactor, stir, after completely dissolving, add ferric oxide, stir for 0.5h; The weight ratio of ferric oxide is 1:5:0.3;

[0041] (2) Add dropwise the PLGA / ferric oxide mixed solution obtained in step (1) to the PVA / tetrahydrofuran mixed solution. After the dropwise addition, stir for 1 hour, remove tetrahydrofuran under reduced pressure at 50°C to obtain loaded ferric oxide PLGA nano-microspheres; the weight ratio of the PVA to the ferric oxide is 1:0.12; the weight ratio of the PVA to the tetrahydrofuran in the PVA / tetrahydrofuran mixed solution is 1:3;

[0042](3) Add the PLGA nanospheres loaded with ferric oxide obtained in step (2), agarose, deionized water, and farnesol to the reactor, stir for 0.5h, heat up to 80°C, stir for 2h, and let stand Cool to 30°C, add cellulase, and stir fo...

Abstract

The invention provides an environment-friendly organic garden overlay composition which comprises the following components in parts by weight: 30-50 parts of garden wastes, 1-15 parts of honeycomb activated carbon, 5-20 parts of zeolite particles, 2-10 parts of an adhesive, 3-15 parts of modified chitosan, 10-30 parts of a matrix material and 10-30 parts of water. The modified chitosan is a chitosan-grafted imidazole heterocycle-containing biquaternary ammonium salt; the matrix material comprises the following raw preparative materials: PLGA, ferroferric oxide, polyvinyl alcohol, agarose, cellulase and farnesol; and the adhesive comprises the following raw preparative materials: ethylene-vinyl acetate copolymer, polyvinyl alcohol, a nonionic surfactant, an anionic surfactant, an anticorrosive and bactericidal agent and water.

Description

technical field [0001] The invention relates to the technical field of garden planting, in particular, the invention relates to an environment-friendly garden organic covering composition. Background technique [0002] In recent decades, due to the interference and impact of human activities on the natural environment in the world, climate anomalies, soil erosion, and water resource scarcity will be long-term problems in the living environment that plague human beings. In the past ten years, my country's southern floods and northern droughts have intensified, and disastrous climates have occurred frequently, all of which are related to the deterioration of the natural environment. At the same time, the country is getting stronger and stronger, and the degree of urbanization is getting higher and higher, but people have higher requirements for the living environment. However, large areas of shrubs and lawns in urban gardens consume serious water, so "water-saving gardens" are...
