Method for producing seedling growing containers from long fibers of straw

Abstract

The invention provides a method for producing seedling growing containers from long fibers of straw, and belongs to the technical field of agricultural seedling growing containers. By the aid of the method, problems in the aspect of straw returning and utilization mainly can be solved. The method is characterized by comprising four steps of collecting the straw; manufacturing straw smashed materials; proportionally mixing and stirring the straw smashed materials, bentonite and polyacrylamide with one another to obtain mixtures; carrying out spinning forming on the mixtures. Smashing processing refers to smashing the straw by the aid of a hammer mill with a rubbing function, the straw can be completely smashed at one step without screen cloth, water is added into the polyacrylamide, and the polyacrylamide is diluted to obtain adhesive; the lengths of long fiber strands of the straw range from 2.0 mm to 300 mm. The method has the advantage that eggs, soil-borne diseases and weed seeds can be eliminated by the seedling growing containers produced by the aid of the method.

Description

technical field [0001] The invention belongs to the technical field of agricultural seedling-raising containers, and in particular relates to a production method of a straw long-fiber seedling-raising container. Background technique [0002] As a mature technology with significant efficiency and effect on plant growth and development, container seedling planting has been widely used in agricultural and forestry production practices. At present, the seedling containers used on a large scale are mainly plastic or rubber seedling containers, which are generally made of (PP, PVC, PS) and other materials. When transplanting, the shell of the seedling container needs to be removed before planting in the planting hole. , such operating procedures and the use of plastic seedling containers have the following problems: [0003] 1. When seedlings are raised in plastic nutrient pots, the root system of the seedlings cannot penetrate the container wall to form nest roots, crooked roots...

AI Technical Summary

Problems solved by technology

[0003] 1. When seedlings are raised in plastic nutrient pots, the root system of the seedlings cannot penetrate the container wall to form nest roots, crooked roots, thin roots, and rotten roots. As a result, the growth and development of the planted plants are often poor, resulting in losses;

[0004] 2. When removing the shell of the seedling container, it is easy to lose the root system, especially the hairy root system. At the same time, it is easy to lose the soil around the seedling root system and even the water inside the root system, reducing the vitality of the root system and resulting in a decrease in the survival rate of planting;

[0005] 3. Planting requires a lot of labor, labor-intensive, time-consuming, and increases labor costs;

[0006] 4. Environmental problems caused by plastics, especially recycled plastics

Due to the high crushing cost and large transportation damage, the large-scale application of this technology also has great limitations.
