Description

Non-woven fabrics grows seedlings and container of growing seedlings

Technical Field

The application relates to the technical field of agricultural seedling raising, in particular to a seedling raising non-woven fabric and a seedling raising container.

Background

The plant cultivation process generally has a seedling raising stage, and in the traditional seedling raising, both cutting seedlings and seeding seedlings have some congenital defects. Because the seedbed is repeatedly used for a plurality of times, the soil root knot nematode is damaged due to frequent continuous cropping. The planted seedlings are frequently pulled out and transplanted in the later period of seedling transplanting and grading procedures, root systems are easily injured by the seedlings after seedling transplanting, soil is not contained, the survival rate of small seedlings is greatly influenced by a long seedling recovery period after transplanting, and therefore the problem of field seedling raising is solved by using a container seedling raising mode in the follow-up period.

The existing traditional seedling raising container is mainly made of soil nutrient bowls and plastic materials, the soil nutrient bowls are labor-and time-consuming, and the quality control of nutrient soil is unstable; the plastic container is mainly made of polyolefin materials, so that the plastic container is difficult to degrade, and the plasticizer used in plastic production can damage soil texture; the plastic seedling raising container has poor ventilation and poor hygroscopicity, and because the plastic film has extremely strong toughness, plant roots are not easy to penetrate through the film to grow out, and bad root conditions such as nest roots, askew roots and the like are easy to generate, the survival rate of seedling raising is reduced. With global warming, china pays attention to environmental protection, and non-woven fabrics are gradually adopted to replace the traditional plastic seedling raising containers for raising seedlings.

The main material of the conventional non-woven fabric used at present is polypropylene, which is also PP polypropylene plastic material produced by different processes, is plastic in nature, but is easier to photolyze into plastic powder compared with a plastic film, but finally exists in soil as a plastic powder component, the plastic powder is difficult to degrade and easy to cause soil hardening, and meanwhile, plasticizer substances used in the production process cause certain damage to the soil.

In addition, there are also the ones that use pure natural plant fiber as the main raw material of the base cloth, such as represented by the environment-friendly type bast fiber film (patent publication No. CN 101889489B) developed by the national academy of agricultural sciences bast of China. However, the gaps of the hemp fibers are larger, the distribution of the thicknesses of the fibers is uneven, so that the irrigated water is easy to leak out of the gaps instantly, the seedling root system habitually grows downwards along the trend of the water flow, and does not grow uniformly to the periphery, so that the damage of the seedling root system easily occurs during transplanting, the transplanting survival rate is affected, the rigidity of the hemp fibers is poor, the curling transportation is not facilitated, and the problems of low strength, easiness in breaking, inapplicability to mechanized transplanting and the like exist.

Meanwhile, plant fiber base is adopted to prepare a seedling raising container, such as corn stalk, sorghum stalk, rice straw, wheat straw, cotton stalk and the like are mainly adopted as plant fiber raw materials, and a proper amount of additives such as adhesives, auxiliary agents and the like are added for production. The preparation method comprises the main processes of crushing corn straw, sorghum straw and other materials, and then adding an adhesive for hot press molding. The prepared container plant is difficult to penetrate in root system and easy to swell and disintegrate when meeting water; meanwhile, reinforcing bodies are frequently used for preparing plant fiber-based seedling raising containers to increase the tensile strength, the elastic modulus, the impact strength and the like of a matrix material, and the reinforcing bodies mainly used at present are organic synthetic polymers such as polyacrylamide reinforcing bodies, but the reinforcing bodies have low effective components, high cost and difficult degradation to cause pollution; starch reinforcements are inexpensive, but have poor reinforcement effects; phenolic resin and resin cyanamide are used as reinforcement, so that the cost is high and pollution is caused.
