The application discloses a fertilizer composition with the functions of controlling growth and expanding fruits and a preparation method thereof, and belongs to the technical field of fertilizer preparation. The fertilizer composition comprises amino acid, plant extract and hydrogel in a weight ratio of 1:(0.1-0.2):(0.3-0.35), wherein the amino acid and the plant extract are dispersed in the hydrogel; the amino acid comprises at least one of L-methionine, L-proline and L-arginine; the plant extract comprises radix codonopsis stem extract 10-15 parts, taxus chinensis leaf extract 18-20 parts, Polygonum orientale extract 8-10 parts and giant knotweed extract 5-6 parts in terms of weight fraction; and the hydrogel comprises sodium alginate 15-20 parts, acrylic acid 70-80 parts, allyl glycidyl ether 12-15 parts, crosslinking agent 4-6 parts and initiator 0.35-0.5 parts in terms of weight fraction. The fertilizer composition can expand fruits on the basis of continuously controlling growth, thereby improving the yield and quality of crops and simultaneously reducing food safety risks.

This invention discloses a combination of metabolic biomarkers, identification methods, and applications for distinguishing between *Polygonum multiflorum* and its closely related species, *Polygonum chinense*. This invention employs ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS / MS) technology, integrating non-targeted metabolomics and statistical analysis (principal component analysis (PCA), sparse partial least squares discriminant analysis (SPLS-DA), and univariate analysis) to efficiently screen candidate biomarkers with identification potential, thereby achieving the identification of *Polygonum multiflorum* and its closely related species, *Polygonum chinense*.

This invention relates to the field of traditional Chinese medicine (TCM) technology, and particularly to a TCM composition for promoting hair growth and its preparation method and application. The TCM composition is prepared from the following raw materials in parts by weight: 1-8 parts dandelion, 1-8 parts *Polygonum chinense*, 1-8 parts *Gastrodia elata*, 2-10 parts mulberry leaf, 1-8 parts *Achyranthes bidentata*, 1-8 parts *Taxillus chinensis*, 4-12 parts *Platycladus orientalis* leaf, 2-10 parts *Eclipta prostrata*, 1-8 parts *Ligustrum lucidum*, 2-10 parts *Polygonum multiflorum*, 2-6 parts black jujube, 1-8 parts *Lonicera japonica* vine, and 1-8 parts *Angelica dahurica*. The TCM composition is used to prevent or treat hair loss, with rapid and significant effects, high safety, and generally does not cause side effects or adverse reactions, nor does it cause excessive irritation.
