Rootzone heating for energy conservation using latent heat storage

摘要

The invention provides improved compositions and methods for growing and cultivating plants, wherein the compositions and methods comprise placing phase change materials (PCMs) close to, in contact with, or substantially in contact with, a plant root system, a plant pot or a plant soil (containing plant roots) to absorb the heat from the day and release it at night.

主权项

1. A plant pot or a plant container comprising:
a phase change material (PCM) or a composition comprising a PCM, wherein the plant pot or plant container is formed from or has as part of its structure or has as a structural component comprising the PCM or composition comprising the PCM, and a sufficient amount of PCM is provided in or part of the plant pot or plant container to maintain a root zone environment having a consistent temperature environment or optimal temperature environment for a plant's root system growth or maintenance, and wherein the PCM or the composition comprising the PCM: (a) is positioned in as part of the plant pot or plant container to be approximate to, close to, in contact with, or substantially in contact with, the plant root system or a soil, or (b) is present as part of or as a structural component of the plant pot or plant container, in an amount sufficient to maintain a root zone environment having a consistent temperature environment or optimal temperature environment for the plant's root system growth or maintenance.
