Description

Technical field[0001]The invention specifically relates to a fluorescent powder capable of promoting plant growth and a preparation method thereof.Background technique[0002]The main technical means to increase crop yields include biotechnology, chemical methods, and physical methods. Biotechnology such as hybrid rice, chemical methods such as the application of fertilizers and hormones, and physical methods including humidity and light control to promote plant growth. The existing problems of greenhouse planting are short days and long nights in winter, insufficient crop light, affecting photosynthesis, reducing crop yields, and lack of light also affecting flowering, pollination, fruiting and other issues. Visible light has a regulatory effect on plant photosynthesis, growth and development, and morphological material metabolism.[0003]According to the light required by the law of plant growth, artificial light is used instead of sunlight to provide supplementary light for all aspec...
