Description

Technical Field

[0001] The invention belongs to the technical field of environment-friendly seedling raising pots, and in particular relates to an environment-friendly seedling raising pot based on straw and cellar mud and a process method thereof. Background Art

[0002] In the field of agriculture and forestry, disposable plastic containers are often used for seedling cultivation due to production needs. With the continuous development of the petroleum industry and the plastics industry, environmental problems caused by the difficulty of plastic degradation have become increasingly prominent. The country has successively introduced many policies to restrict the use of disposable plastic products and formulated relevant inspection and testing standards. However, traditional plastic seedling containers are difficult to degrade in the natural environment and can only be partially degraded. In the natural environment, the accumulated plastic in the soil can be broken down into microplastic particles with a diameter of less than 5 mm through degradation such as photodegradation, thermal oxidation degradation or aging degradation, which has caused serious damage to the natural environment and seriously endangered people's health. It has no significant advantages in nature and society.

[0003] The main plastic seedling containers used in China are basically made of PE, PVC and other products. Their disadvantages are: (1) Plastic seedling containers have poor water permeability and air permeability, which can easily have an adverse effect on the growth of seedling roots; (2) Plastic has certain strength and toughness, which will hinder the extension of seedling roots during the growth and development of seedlings, resulting in the phenomenon of spiral root growth. The seedlings will gradually improve after a long time after planting; (3) Plastic is particularly difficult to degrade in the natural environment and will cause great pollution to the environment. Among all degradable seedling containers, plant fiber-based seedling containers are the most concerned and are also the key development direction in the future. At present, the preparation of plant fiber-based seedling containers mainly uses agricultural residues such as corn stalks, sorghum stalks, rice straw, wheat straw, cotton stalks and other plant fiber raw materials as reinforcing materials, and adds appropriate amounts of composite additives for production.

[0004] Chinese patent application No. 201510869187.3 discloses a nutrient pot for seedlings, which is made of a pot body and a nutrient matrix arranged in the pot body, wherein the pot body is made of the following components by weight: 100 kg corn stalks, 100 kg clay, 5 kg citric acid residue, 2 kg garlic leaves, 2 kg senna leaves, 2 kg bran, 0.5 kg salt, and 2 kg sesame leaves; the above-mentioned nutrient matrix is ​​made of the following components by weight: 100 kg urea, 200 kg calcined loess powder, nitrogen Fertilizer 50kg, magnesium sulfate 10kg, plant ash 10kg, leaf humus 300kg, cellar mud 100kg, rooting powder 5kg, sea mud 20kg, erythromycin ointment 0.2kg, 1.8% avermectin emulsifiable concentrate 200ml, clove leaf dry powder 0.6kg, sodium selenite 2kg, saponin 0.2kg, potassium humate 1kg, potassium dihydrogen phosphate 30kg, seaweed micropowder 10kg; the nutrient matrix can not only provide the nutrients required for the normal growth of seedlings, but also reduce the occurrence of seedling diseases and insect pests. However, the patent directly adds straw, and the binding force between it and clay is not strong, which may lead to the instability of the structure of the seedling pot; at the same time, there is also uneven mixing of various materials, inconsistent materials of various parts of the container, resulting in poor mechanical properties, poor toughness and brittleness of the product, and high drop breakage rate. Chinese patent application No. 201710946606.8 discloses a degradable seedling tray and its preparation method, which is made of the following raw materials in parts by weight: 75-85 parts of deinked pulp, 50-60 parts of plant fiber, 0.5-1 parts of straw fermentation agent, 22-24 parts of modified starch, 4-6 parts of adhesive, 1-1.5 parts of release agent, 4-6 parts of nutrient agent, 0.8-1.2 parts of antibacterial agent, and 3-5 parts of waterproof film. The invention has a certain salt-alkali resistance to decomposition, is separated from the outside world during the adaptation period of the seedlings, and is degradable. After the seedlings adapt to the salt marsh environment, their roots can grow through the plug tray and eventually completely degrade. However, the amount of modified starch used in this patent is large, and the production cost is relatively high.

[0005] Based on this, this field urgently needs environmentally friendly, root growth-friendly, degradable seedling containers to fill the market. Summary of the invention

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an environmentally friendly seedling raising pot based on straw and cellar mud and a process method thereof. The straw, cellar mud and other additives used in the environmentally friendly seedling raising pot are all degradable materials with low production cost and can be degraded.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A process for an environmentally friendly seedling raising pot based on straw and cellar mud comprises the following steps:

[0009] (1) Pretreatment of straw: the straw is washed and dried, crushed to 60 mesh, and then immersed in hydrogen peroxide and ferric chloride solution. After the immersion treatment, the residual liquid is discarded, and the straw is dried to a moisture content of no more than 10% to obtain pretreated straw;

[0010] (2) Straw modification: The pretreated straw in step (1) is placed in a sealed glass box and irradiated using an electron beam irradiation bowl, and then the irradiated straw is added to an alkaline solution for stirring and reacting. After the reaction is completed, the straw is filtered, washed, and dried to obtain modified straw;

[0011] (3) Pretreatment of pit mud: adding the pit mud to the aqueous solution of silane coupling agent, then placing it in a ball mill for ball milling, and drying it at 40-50° C. after the ball milling, to obtain the pretreated pit mud;

[0012] (4) Preparation of environmentally friendly seedling raising pots: The modified straw in step (2) and the pretreated pit mud in step (3) are mixed evenly, and then seaweed glue, wood ash, polyvinyl alcohol and water are added and stirred evenly. Then, the mixture is placed in a mold, subjected to compression molding, molding, demolding and sun drying to obtain the environmentally friendly seedling raising pots.

[0013] Preferably, the straw in step (1) is one or both of corn straw and rice straw, the mass concentration of the hydrogen peroxide is 10-15%, the concentration of the ferric chloride is 1-2 mol / L, and the volume ratio of the hydrogen peroxide to the ferric chloride solution is 1:1-2.

[0014] Preferably, the immersion temperature in step (1) is 50-60° C., and the immersion time is 0.5-1 h.

[0015] Preferably, the irradiation conditions in step (2) are: electron energy is 5-10 MeV, irradiation dose is 5-10 Mdelamin; and the alkali solution is 1-2 mol / L sodium hydroxide.

[0016] Preferably, the reaction temperature is 20-30°C and the reaction time is 20-40 min.

[0017] Preferably, the mass concentration of the silane coupling agent aqueous solution in step (3) is 3-6%, and the silane coupling agent is one of KH550, KH560, and KH570; the mass ratio of the pit mud to the silane coupling agent aqueous solution is 100:30-50.

[0018] Preferably, the ball milling speed in step (3) is 2000-3000 r / min, and the time is 30-50 min.

[0019] Preferably, the mass ratio of the modified straw, pretreated pit mud, seaweed glue, plant ash and polyvinyl alcohol in step (4) is 40-50:40-60:5-10:10-20:5-10:80-120.

[0020] Preferably, the stirring time in step (4) is 30-60 min.

[0021] The present invention also protects an environmentally friendly seedling pot based on straw and cellar mud prepared by the process method.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) The method for preparing an environmentally friendly seedling pot based on straw and cellar mud provided by the present invention comprises the following steps: pre-treating the straw, and then impregnating the straw with hydrogen peroxide and ferric chloride to effectively improve the adsorption capacity of the straw; then, electron beam irradiation and alkaline solution soaking are performed, and the straw is bombarded with high-energy electron beams to produce defects on the surface of the straw. Since these defects have greater reactivity than the normal carbon atoms on the surface of the straw, the subsequent reactivity of the straw is improved. At the same time, the alkaline solution also destroys the chemical bonds between cellulose and other components in the straw, causing a saponification reaction and dissolving impurities such as pectin in the straw, increasing the roughness of the straw surface, and improving the adsorption performance of the straw; pre-treating the cellar mud can introduce groups with higher reactivity to its surface, and at the same time, the ball milling method can effectively reduce the damage to microorganisms in the cellar mud compared with other chemical methods; the present invention modifies the straw and pre-treats the cellar mud, so that the straw and the cellar mud are combined in the form of covalent bonds, so that the connection between the straw and the cellar mud is tighter, thereby improving the mechanical properties of the environmentally friendly seedling pot.

[0024] (2) The method for preparing an environmentally friendly seedling pot based on straw and cellar mud provided by the present invention mainly selects straw and cellar mud as raw materials. The cellar mud contains a large number of active microorganisms, which promote the growth of plants. The addition of cellar mud can increase the water retention and wettability of the matrix, but the addition ratio should be between 40-60%. Too much addition will lead to poor air permeability. Corn straw and rice straw with high cellulose content are selected to facilitate the molding of the seedling pot. At the same time, the added raw materials such as alginate, wood ash and polyvinyl alcohol are degradable materials, and the production cost is low.

[0025] (3) The environmentally friendly seedling raising pots based on straw and cellar mud provided by the present invention have all degradable raw materials added, which can provide partial nutrition for the seedlings on the one hand, and solve the recycling of agricultural waste and reduce environmental pollution on the other hand; the prepared seedling raising pots do not need to be removed from the tray, do not damage the roots, and are more conducive to the survival of the seedlings.
