Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of green recycled paper, in particular to a green recycled paper for saline-alkali land improvement, land warming, fertilizing and weeding. Background Art
[0002] Soil salinization is one of the current global ecological and environmental problems, seriously affecting local food production, the income of farmers and herdsmen, and the development of modern agriculture and animal husbandry. The surface soil of saline-alkali land often hardens, resulting in reduced soil water permeability, reduced nutrient content, increased concentration of harmful ions, and adverse effects on crops. Therefore, it is difficult for crops to survive in saline-alkali soil. Different environments can lead to different types of saline-alkali soil, having negative impacts on agriculture, animal husbandry, and the ecological environment of each region.
[0003] Currently, there are many improvement measures for saline-alkali land, such as physical improvement, chemical improvement, and screening of salt-tolerant varieties. However, how to improve the yield and survival rate of rice in saline-alkali land and reduce labor costs remains an issue worthy of attention.
[0004] Due to the high content of harmful ions and pH in saline-alkali land, commonly used soil conditioners at present include using organic fertilizers to reduce pH, improve plant growth, and enhance tolerance to stress. However, in saline-alkali land, during various growth stages of rice, due to changes in external conditions, there may be a need to supplement or continuously apply conditioners. At the same time, paddy fields also face problems such as weeds and insufficient accumulated temperature, and solving them requires a large amount of human and material resources. When planting rice on saline-alkali land, during the tillering stage, it is impossible to drain water and ventilate, and the roots of rice are blocked due to lack of oxygen. In this case, it is necessary to add oxygen-increasing agents to the paddy field to promote the root development of rice. At the same time, the chemical substances of herbicides penetrate into the soil, which will have adverse effects on soil microorganisms and plants, may lead to a decline in soil quality, and reduce farmland productivity. The widespread use of herbicides may damage the surrounding ecosystem, kill wild plants, and also have adverse effects on wild animals such as birds and insects, resulting in a reduction in biodiversity. Overuse of herbicides may also cause weeds to gradually develop resistance to these chemical substances, resulting in more chemical substances entering the environment. Content of the Utility Model

[0015] Figure 1Schematic diagram of the structure of the green recycled paper for saline-alkali land improvement, land warming, fertilization and weeding according to an embodiment of the present utility model.
[0016] In the figure, the corresponding relationship between each component and the reference numeral is as follows:
[0017] 1. Humic acid recycled paper, 2. Mixed material layer, 3. Straw recycled paper. Detailed implementation manners
[0018] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0019] The present utility model will be further described in detail below with reference to the accompanying drawings:
[0020] As Figure 1 shown, a green recycled paper for saline-alkali land improvement, land warming, fertilization and weeding according to the present utility model includes: a humic acid recycled paper 1, a straw recycled paper 3, and a mixed material layer 2;
[0021] The humic acid recycled paper 1 is made by adding humic acid to the straw recycled paper 3, and the mixed material layer 2 is placed between the humic acid recycled paper 1 and the straw recycled paper 3;
[0022] The mixed material layer 2 adopts a sheet structure formed by mixing fertilizer and oxygen enhancer.
[0023] In this embodiment, the recycled paper prepared from straws such as rice straws sandwiches the mixed material layer 2 of the oxygen enhancer that slowly releases oxygen in segments and fertilizer between two layers of recycled paper. One of the two layers of recycled paper is a humic acid recycled paper, and the other layer is an ordinary straw recycled paper 3. The green recycled paper is easy to obtain raw materials, degradable, environmentally friendly, and can continuously provide good conditions for crop growth, reducing the number of fertilization times. At the same time, covering the recycled paper on the soil can warm the land and prevent the growth of weeds.
[0024] Specifically, the raw material of the green recycled paper is made of cellulose pulp from the by-products (such as rice straws) remaining after crop harvesting, and can be naturally decomposed into nutrients in the paddy field. One layer of the humic acid recycled paper 1 is added with humic acid powder, which can form a black paper, thereby reducing the light transmittance. Covering the green material on the soil can warm the land and help warm the land and maintain the temperature.
[0025] The green recycled paper is covered on the soil, which can hinder the growth of weeds on the covered area. The organic fertilizer in the mixture layer 2 of the green recycled paper is slowly released into the soil, reducing the pH of the soil environment and accelerating the degradation of the green recycled paper at the same time. The oxygenating agent in the mixture layer 2 can slowly release nutrients, increase the vitality of plant roots, and avoid affecting their normal respiration and growth due to lack of oxygen.
[0026] The present invention aims to improve the sustainability of crop (such as rice) cultivation, reduce environmental pollution, and provide organic matter for the soil. At the same time, the green recycled paper can improve the soil structure, promote microbial activities, provide nutrients required by plants, and shade and remove weeds.
[0027] During implementation, the width of the green recycled paper can be set according to the plant spacing of the crops in the plot to be improved, making it applicable to fields with various plant spacings. It can also be rolled up for convenient transportation and use. The green recycled paper can be laid on the land between the crops, or can be laid on the entire plot along with seeding using a special transplanter, or can be applied to some plots in anaerobic environments or saline-alkali patches.
[0028] In the above embodiment, preferably, the light transmittance of the material of the green recycled paper is not greater than 30%, and when it covers the paddy field, it can effectively block the growth of weeds, thus playing a role in weed control.
[0029] In the above embodiment, preferably, the degradation time of the green recycled paper is less than 30 days.
[0030] In the above embodiment, preferably, the fertilizer is a mixture of one or more of humic acid fertilizer, manure, and inorganic mixed fertilizer.
[0031] In the above embodiment, preferably, the oxygenating agent is a mixture of one or more of calcium peroxide, magnesium peroxide, and urea peroxide.
[0032] In the above embodiment, preferably, the amount of active oxygen applied by the oxygenating agent is not less than 2.548 mg / m 2 , which can slowly release nutrients, stably increase the vitality of plant roots, and avoid affecting their normal respiration and growth due to lack of oxygen.
[0033] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, various changes and modifications can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
