‌Naphthaleneacetic acid (‌ NAA) ‌ is a synthetic plant growth regulator. ‌ belongs to the naphthaleneacetic acid (‌ NAA), and ‌ can promote plant growth and development. ‌ Its instructions include the following: ‌

Properties and mechanism of action: ‌

Naphthalene acetic acid is a potent plant growth regulator ‌ that affects plant growth and development by regulating the synthesis and metabolism of plant hormones. ‌
It can be absorbed and transported through plant tissues such as roots, ‌ stems and leaves, ‌ plays a regulatory role in plant growth and development. ‌
Main function: ‌

Promotes root development: ‌ increases the number of root branches and root hairs ‌ thereby enhancing the plant’s ability to absorb water and nutrients. ‌
Promote fruit expansion: ‌ in the growth process of fruit trees and vegetables, ‌ promote fruit expansion, ‌ increase fruit yield and quality. ‌
Promote flower bud differentiation: ‌ improve the ornamental value of flowers. ‌
Increase fruit uniformity: ‌ regulate the growth rate of fruit, ‌ make the fruit mature evenly, ‌ improve the commodity value of fruit. ‌
Usage: ‌

Application dose: ‌ fruit trees and vegetables application dose of 100-200 mg per mu of naphthalene acetic acid solution, ‌ flowers application dose of 1-2 mg per liter of water. ‌
Fertilization time: ‌ is determined according to the growth stage of plants. ‌ fruit trees and vegetables can be fertilized in the flourishing growth stage and fruit expansion stage, ‌ flowers can be fertilized in the flower bud differentiation stage and flowering stage. ‌
Application method: ‌ can be applied by two ways: leaf spraying and root watering. ‌ For fruit trees and vegetables, ‌ can be evenly sprayed on the leaves of naphthalene acetic acid solution; ‌ For flowers, ‌ a solution of naphthalene acetic acid can be poured in the soil around the roots. ‌
Note: ‌

When using naphthalene acetic acid, ‌ should pay attention to the dose control, ‌ to avoid excessive use of abnormal plant growth or produce negative effects. ‌
The timing of application should be determined according to different plants and application purposes, ‌ choose the right growth stage to fertilize, ‌ for the best results. ‌
Naphthalene acetic acid should be stored in a dry, ‌ cool place ‌ away from fire sources and children
