Problems solved by technology

However, the existing bio-based seedling pots are mainly made of crop straw and pulp, which have the disadvantages of complicated pre-treatment and high cost.
In addition, the existing bio-based seedling pots still have the following problems: (1) The compressive strength is poor, and it is easy to cause structural collapse and damage during transportation, which cannot meet the strength requirements during transportation; (2) The service life is short, It is easily degraded during use and cannot meet the life requirements during use

Abstract

The invention discloses a citrus-pomace-based completely-degradable seedling pot and a preparation method thereof. The citrus-pomace-based completely-degradable seedling pot is prepared through hot press molding by adopting citrus pomace, an adhesive, wood flour and / or straw as raw materials. The citrus-pomace-based completely-degradable seedling pot has the advantages of being good in compression-resistant property and long in service life, meanwhile further has the good mechanical compression-resistant and falling-resistant properties, water resistance, water absorption and water-retaining property, is free of pollution to the environment, is a completely-degradable environment-friendly product, and has good application value and application prospects; and the preparation method of the citrus-pomace-based completely-degradable seedling pot has the advantages of being simple in process, easy to control, low in cost and the like, and is suitable for large-scale preparation and beneficial to industrial production.

Description

technical field [0001] The invention relates to a completely degradable seedling raising pot based on citrus peel residue and a preparation method thereof. Background technique [0002] At present, the main raw materials for preparing seedling pots are petroleum-based materials (polyethylene, polypropylene, etc.) When planting, it is necessary to separate the seedlings and pots, which may damage the roots and seedlings and reduce the survival rate of seedlings. The bio-based seedling pots made of bio-based materials have a wide range of raw materials and are less harmful to the environment, which is the main direction for the development of seedling pots in the future. However, the existing bio-based seedling pots are mainly made of crop stalks and pulp, which have disadvantages such as complicated pre-treatment and high cost. In addition, the existing bio-based seedling pots still have the following problems: (1) The compressive strength is poor, and it is easy to cause s...
