Plants use moderate amounts of plant growth regulators during seedling to achieve twice the result with half the effort. In fact, plant growth regulators are substances that can be called “hormone†in plants. They are rare in content but important in function, which can effectively control plant rooting, germination, growth, flowering and fruiting. The whole process of growth and development. Here is a brief introduction to the role of plant growth regulators in the application of nursery:
1. It can control seed dormancy and increase seed germination rate. Seeds that have a long dormant period or are difficult to germinate, can be broken by dormancy after some plant growth regulator soaking, and accelerate the germination due to the activity of enzymes in the seed. Such as naphthaleneacetic acid, gibberellin, Jin baby root Miao Zhuang and so on.
2, can promote the rapid rooting of cuttings. It is often used to cut tree species that are difficult to root and promote root cell division through the treatment of plant growth regulators. Such as indole acetic acid, naphthalene acetic acid, indole butyric acid, Jin baby root Miao Zhuang and so on.
3, can improve the graft survival rate. During the grafting process, by using the plant growth regulator to dip or apply the cutting surface of the scion and the rootstock, the recovery of the injured tissue of the incision is promoted, thereby facilitating the healing of the interface and improving the graft survival rate. Such as sitting fruit spirit, Jin baby root Miao Zhuang, å²å“š é…¸ acid, anti-falling.
4, seedling transplant period can effectively promote root wound healing. When seedlings are transplanted, it is easy to reduce the survival rate of seedlings due to root injury. At this time, the seedlings should be dipped in the appropriate amount of plant growth regulator after the seedlings are soiled, which can effectively promote wound healing and promote the growth and development of the roots, thereby effectively increasing the survival rate of the seedlings.
