Description

Technical Field

[0001] This invention relates to the field of seedling substrate technology, specifically to a seedling substrate made from rosemary extract residue and its preparation method. Background Technology

[0002] The seedling substrate is made by mixing peat moss, vermiculite, and other additives in a certain proportion. It is the main source of nutrition and energy for seedlings during germination, providing them with abundant nutrients. However, if the seedlings in the cotyledon stage have poor root absorption, or if the substrate bed temperature is too high or respiration is too strong, the stored nutrients will gradually decrease, resulting in few photosynthetic products and poor seedling growth, particularly slow cotyledon growth. The various trace elements abundant in the seedling substrate effectively solve this problem. During the growth process, the growth and development of different organs are interconnected, normally exhibiting mutual promotion. Some photosynthetic products from the stems and leaves are transported to the roots to support root growth, while the nutrients and water absorbed by the roots from the soil environment are used to support stem and leaf growth, enhancing photosynthesis and increasing nutrient accumulation and transport.

[0003] Existing seedling substrates are mainly composed of peat moss, vermiculite, and other additives in a certain proportion. However, peat moss and vermiculite cannot provide terpenes and flavonoids, which are essential components for plant growth, thus affecting the growth of the prepared substrate.
