Problems solved by technology

However, since organic wastes are not easy to mold, when preparing seedling pots by hot pressing, it is first necessary to crush and pulp agricultural organic wastes such as corn stalks or rice stalks, and then preheat the mould. Then heat the material, or directly preheat the material, so that the lignin in the corn straw or rice straw reaches the glass transition temperature, so that the corn straw or rice straw is hot-pressed in the mold, and the straw fiber reaches the glass transition temperature. The lignin strengthens the bonding and molding of straw fibers. When using this method to prepare seedling pots, due to heating the mold or raw materials, the preparation of seedling pots consumes a lot of energy, production efficiency is low, and the cost increases.

Embodiment 1

[0028] Weighing raw materials: 46 parts of gasification filter cake, 37 parts of decomposed cow dung, 11 parts of straw, 0.4 parts of polyacrylamide, 1 part of calcium sulfate, 4 parts of double superphosphate, 0.5 parts of corn steep liquor binder and compound nitrophenol Sodium 0.1 part.

[0029] Stir the decomposed cow dung, crushed straw and gasification filter cake evenly, then add calcium sulfate, double superphosphate, sodium nitrophenolate and polyacrylamide and mix evenly to obtain a mixture, and spray the corn steep liquor adhesive diluted 1000 times on the above In the mixture, the moisture content of the mixture is 55%, and after being stirred evenly, it is placed in a grinding tool for 0.5MPa high-pressure extrusion to form a circular seedling pot with a wall thickness of 1.2cm, a diameter of 12cm, and a length of 20cm, and is dried.

Embodiment 2

[0031] Same as Example 1, the difference is that 40 parts of raw material gasification filter cake, 35 parts of decomposed cow dung, 10 parts of rice straw, 0.5 part of polyacrylamide, 0.5 part of calcium sulfate, 2 parts of heavy superphosphate, 0.2 parts of corn steep liquor binder part and 0.1 part of sodium nitrophenolate.

Embodiment 3

[0033] Same as in Example 1, the difference is that the gasification filter cake is completely replaced with straw.

Abstract

The invention relates to the technical field of waste resource utilization and ecological environment management, in particular to a seedling pot and a preparation method thereof. The raw materials of the seedling pot include: gasified filter cake, decomposed cow dung, straw, polyacrylamide, calcium sulfate , double superphosphate, corn steep liquor binder and sodium nitrophenolate; the present invention uses the gasification filter cake as the main raw material of the seedling pot, and realizes the harmless and resourceful utilization of the coal chemical waste gasification filter cake The invention provides a degradable nursery pot with remarkable ecological benefit and economic benefit.

Description

technical field [0001] The invention relates to the field of cultivation technology, in particular to a seedling raising pot and a preparation method thereof. Background technique [0002] Numerous deserts and arid areas in Ningxia have low vegetation coverage, and it is difficult to plant green seedlings under conditions of drought and water shortage. Seedling pot is an agricultural auxiliary equipment that protects plant roots and promotes plant growth. It is widely used in agricultural production processes such as flower tissue culture, vegetable planting, and rice seedling transplantation. Transplanting in dryland can significantly improve the survival rate of dryland vegetation and become a powerful measure to control soil drought and desertification. Plastic pots are commonly used seedling pots in the prior art, but they also have defects such as difficult demoulding of seedlings and damage to plant roots. In order to overcome the application defects of plastic seedl...
