Amino acid is a general name for a class of organic compounds containing amino and carboxyl groups. It is the basic building block of biological functional macromolecular proteins and the basic substance that constitutes the proteins required for animal and plant nutrition.

Plant growth observation records usually include seed germination, rooting, sprouting, leafing, flowering and other stages. The changes in each stage can be recorded in detail through continuous observation. ‌

Organic water-soluble fertilizers are rich in nitrogen, phosphorus, potassium and other elements, which are the main nutrients required for plant growth and can quickly promote plant growth and development.

Plant growth regulators play an important role in agricultural production. They can enhance the stress resistance of crops, help increase yields, improve product quality, and thus increase the economic benefits of planting. However, if these regulators are used improperly, they may cause crop pesticide damage, which will have an adverse effect on yield and quality, and even increase production costs.
