【1】Promote tree rooting

Mixture of Indole Butyric Acid (IBA) and Naphthalene Acetic Acid (NAA)

Select poplar branches with a thickness of 0.8~1.8cm, cut them into seed strips with a length of about 15cm and a bud at 1cm from the top, and soak them in 80~120mg/L 2% indine naphthalene ethyl soluble powder for 5 hours before Planting can significantly reduce the mortality of poplar cuttings and seedlings, improve the number, length and quality of roots, and promote the increase of poplar seedling height and ground diameter. The upper limit concentration can be used for difficult-to-root seedlings such as maple, pine and fir, and the lower limit concentration can be used for easy-to-root tree species such as willow, French sycamore, and privet.

Naphthalene acetic acid (NAA) and indole acetic acid (IAA)

When poplar and paulownia seedlings were raised, using 250mg/L naphthalene acetic acid solution combined with 250mg/L indole acetic acid solution to soak the cuttings for 2-4 hours could shorten the rooting time by 1/3 and increase the survival rate by about 40%.

【2】Promote the germination of the tree and germinate new branches

Kinetin or Triacontanol

Applying 1mg/L kinetin or 5mg/L triacontanol solution to the annual de-apical stub of Fraxinus mandshurica can significantly promote the bud germination of the de-apical stub leaves and increase the phenomenon of two buds in the same axil.

【3】Promote tree falling and inhibit fruiting

Gibberellic acid (GA3)

In the early stage of flower bud differentiation, treating poplar with 50-100 mg/plant gibberellic acid can completely interfere with the flower bud differentiation of the female plant of black poplar in that year, thereby completely controlling the female plant of black poplar flying in the second year, and the flower control rate reaches 100%, the phenological period was delayed by 7d.

Naphthalene Acetic Acid (NAA)

One or two-year-old Octagonal Begonia was sprayed with 20 mg/L naphthalene acetic acid solution at full bloom stage, and the rate of inflorescence was the highest, reaching 36.1%, and the effect of flower thinning was obvious.

【4】Preserving green and delaying fading

6-BA

Wetland pine10d-year-old etiolated seedlings were immersed in 1mg/L6-BA solution, treated in dark for 16h, transferred to KNO3 solution, and illuminated for 18h, which significantly promoted the formation of chlorophyll in young shoots.

Brassinolide

The 1-year-old seedlings of wetland pine were irrigated with 0.5~1.0mg/L brassinolide solution. The chlorophyll content of the needles treated with brassinolide was significantly higher than that of the control, which had a significant green-keeping effect. At the same time increase the dry matter content and increase the ability to resist adversity.

【5】Promote wound healing

Naphthalene acetic acid (NAA)

According to the test, 200-400mg/L naphthalene acetic acid can quickly promote the formation of callus at the wound and promote wound healing after smearing it on the tree wound.

Cytokinin

In the treatment of garden tree cut stem wounds, 20-100 mg/L liquid medicine can be applied directly to the cut stem wound, and combined with fungicides and preservatives can quickly promote wound healing.

6-BA

In the treatment of garden tree cut stem wounds, 2-35 mg/L liquid medicine can be used to directly apply to cut stem wounds, and the combination of fungicides, polymer films and other materials can quickly promote wound healing.

【6】Suppress the tidbits from flying

Gibberellic acid (GA3)

According to the test, 20000mg/L gibberellic acid can inhibit the willow and sycamore from flying in the next year after acting on willow and sycamore in the form of tree infusion.

Ethephon

Spraying 1000-2500mg/L ethephon solution at the early stage of flowering (mid-April) of Sycamore can significantly promote the drop of Sycamore flowers and fruits, and control the pollution of Sycamore flying.
