Pineapples prefer acidic soil with a pH value between 5.5-6.5. The soil should be well-drained and rich in organic matter and trace elements such as phosphorus and potassium. The soil should be plowed to a depth of about 30 cm for better seed growth.

S-abscisic acid is a plant regulator, also known as abscisic acid. It was named because it was initially believed to promote the shedding of plant leaves. It has effects in multiple developmental stages of plants. In addition to promoting leaf shedding, it also has other effects, such as inhibiting growth, promoting dormancy, promoting potato tuber formation, and plant stress resistance. So how to use S-abscisic acid? What effect does it have on crops?

1. Promote the rooting of cherry rootstock tenderwood cuttings
Naphthalene acetic acid (NAA)
Treat cherry rootstock with 100mg/L of Naphthalene acetic acid (NAA), and the rooting rate of rootstock tenderwood cuttings reaches 88.3%, and the rooting time of cuttings is advanced or shortened.

Plant growth regulators can enhance cell metabolism, promote cell division, and significantly increase the fruit setting rate of jujube trees. Commonly used ones include Gibberellic Acid GA3, 2.4-D, Naphthalene acetic acid (NAA) and Paclobutrazol (Paclo), which have obvious effects on promoting flowering and fruit retention of jujube trees. Gibberellic Acid GA3 is the most widely used in production.
