Correct ways to use vegetable rooting agents
Rooting agents are auxin-type compounds used to promote vegetable growth; the ones commonly used on vegetables include indoleacetic acid and naphthaleneacetic acid. They mainly promote rooting and maintain apical dominance. So what are the commonly used rooting agents, how are they classified, how should they be used, and what does each do? What should be noted after use? These are the things everyone cares about, so please keep reading below.
1. Common classifications
The first type is rooting and seedling-strengthening agents, such as indoleacetic acid, naphthaleneacetic acid, or mixtures of them. Used at the seedling stage and later stages, the effect is obvious but short-lived, and continuous use easily leads to premature aging. The second type combines biological bacteria with rooting agents, such as ABT biological bacteria rooting powder. Used at the initial and early stages, it stimulates root growth and improves the roots' ability to absorb nutrients. The third type is rooting agents that combine nutritional components with growth-promoting substances, such as Fangrun Genjia, which has the characteristics of the first two types and can be used throughout the entire growth period.
2. How to use
In greenhouses with many soil-borne pathogens, use microbial agent types, which can increase beneficial bacteria in the soil and prevent pathogens from multiplying and causing harm. If there are nematodes, it is better to use rooting agents with actinomycete microbial agents, which suppresses nematode occurrence. In drought conditions, apply seaweed acid rooting agents. If rooting is too sparse, use amino acid rooting agents. If rooting is too slow, use nutritional rooting agents.
3. Precautions
Buy suitable rooting agents according to growth needs, and use them continuously for a period of time, otherwise they will not be effective. For microbial types, multiple applications are needed; beneficial bacteria must increase to exceed the pathogens before they can exert a suppressive effect. Do not change rooting agents at will, as the effect will be affected. Use them in suitable weather and when the vegetables are in good condition. Mix the specified concentration, and do not change the concentration at will.
4. Periods of use
During seedling raising, it can be used to speed up germination, produce uniform seedlings, and strengthen seedlings. At the seedling stage, use it when two true leaves have grown to promote root growth and allow earlier transplanting. When transplanting, drench the roots to increase the survival rate, speed recovery, promote rapid rooting, and help roots take hold. During the growth period, it enlarges the root absorption area and prevents root rot and seedling death.
Vegetable rooting agents differ in type and function, and different situations suit different rooting agents. Used at different periods, they have different effects.
