Crops absorb nutrients primarily through two pathways: root absorption and leaf absorption. Root absorption involves applying fertilizers into the soil, where they come into contact with the roots and are absorbed and utilized by the fine roots or root tips, then transported to the roots, stems, leaves, flowers, and fruits of the crop.

Brassinolide and Diethyl aminoethyl hexanoate (DA-6) are commonly used plant growth regulators in agricultural production, and their mixing has always been a focus of attention for farmers and agricultural technicians.

These are primarily used to promote fruit cell division or elongation, increasing fruit set rate and individual fruit weight. They are commonly used in the production of fruits such as grapes, strawberries, and apples.

ubber trees are tall trees with an economic lifespan of several decades, and their latex is harvested by tapping the bark, a unique harvesting method. Rubber is produced from the latex-producing tissue in the bark of the rubber tree. The latex cells utilize the products of photosynthesis—sugars and other nutrients—to biosynthesize rubber through a series of complex enzymatic reactions.
