Embodiment 1

[0041] In this example, the types and amounts of each component in the raw material composition of the degradable seedling pot are shown in Table 1. Add the raw material composition of the degradable seedling pot into the mixer and mix evenly to obtain the primary mixture. The mixing time is 30 minutes, and the rotation speed of the mixer is 200rpm; Press down for 10 minutes to form a degradable seedling pot with small holes on the surface.

[0042] Among them, the moisture content of citrus peel residue is 3%; the content of organic matter in peat is 45%, the specific gravity is 0.85, and the pH is 5.8; the particle size of humus soil is 1200 mesh; the moisture content of humus soil is 8%; The particle size of lactic acid is 100 mesh; the number average molecular weight of polylactic acid is 8000.

Abstract

The invention discloses a degradable seedling raising pot and a raw material composition and a preparation method thereof. The raw material composition of the degradable seedling raising pot comprisesthe following components in parts by weight: 100 parts of citrus peel residues, 50-210 parts of turf, 13-210 parts of humus soil, 4.5-10.5 parts of inorganic minerals, 13-60.5 parts of polylactic acid and 7-16 parts of an adhesive. The degradable seedling raising pot prepared by the method is low in density, relatively high in total porosity, ventilation porosity and water holding porosity, excellent in pressure resistance, water absorption, water retention and air permeability, free of influence on growth of crop seedlings, capable of realizing pot-seedling integrated transplanting, free ofthe problems of damaging crop root systems and the like; and meanwhile, waste is turned into wealth, and efficient utilization of resources is achieved.

Description

technical field [0001] The invention specifically relates to a degradable seedling pot, its raw material composition and a preparation method. Background technique [0002] At present, citrus is the fruit with the largest output in the world, with an annual output of more than 100 million tons. China is one of the main producing areas of citrus, and its output ranks third in the world. The citrus part is used for fresh food, and a large part is used to make products such as fruit wine, fruit vinegar and canned food. Whether it is fresh food or used for production and processing, it is accompanied by a large amount of by-products of citrus peel. Citrus peels contain nitrogen, phosphorus, potassium and other organic components for plant growth, but citrus peels have not been efficiently utilized, resulting in waste of biomass resources. [0003] Polylactic acid is considered to be the most promising new "ecological material" in the industry in the 21st century. Polylactic ac...
