Efficient water soluble root-inducing powcler for taxus media

[0012] Example 1:

[0013] A. Weigh 2.00 g of sodium hydroxide and 9.31 g of α-naphthalene acetic acid (NAA), dissolve them in 50 ml of deionized water, place them in 80° C. drying after dissolving, and grind them into powder.

[0014] B. Weigh 2.00 g of sodium hydroxide and 10.16 g of indole butyric acid (IBA), dissolve them in 50 ml of deionized water, dissolve them, and dry them at 80° C. and grind them into powder.

[0015] A 335.4 mg and B 332.5 mg are weighed into each bag of Taxus mandiensis high-efficiency water-soluble rooting powder, mixed and packaged. Appearance: White powder, soluble in water.

[0016] How to use: Dissolve each bag of rooting powder directly with 1000ml of tap water, cut 10-15cm of Mandia yew cuttings, cut both ends into bevels with a sharp knife, remove 1/3 of the leaves at the lower end, and soak in the above solution for 3 hours, and then inserted into the perlite matrix, maintaining the humidity of the matrix, using a 90% shading net for shade on sunny days, and taking root after 40 days. % (27.5% for the control). The final survival rate reached more than 98%. Using the above-mentioned sound root powder, 80,000 plants are propagated a year.

[0017] Example 2: A. Weigh 9.75 g of potassium hydroxide and 46.5 g of α-naphthalene acetic acid (NAA), dissolve them in 250 ml of deionized water, place them in 70° C. oven after dissolving, and grind them into powder.

[0018] B. Weigh 9.75 g of potassium hydroxide and 51 g of indole butyric acid (IBA), dissolve them in 250 ml of deionized water, place them in 70° C. oven after dissolving, and grind them into powder.

[0019] Each bag of Taxus mandiensis high-efficiency water-soluble rooting powder is weighed with 0.33 g of A and B, and 0.1 g of rare earth micro-fertilizer, mixed well, packaged, and dissolved in 1 liter of tap water per bag. Appearance: White powder with pale pink crystals, soluble in water.

[0026] Grade 1: Stems turn black and no callus. Number of plants × (-4)

[0027] Grade 2: green stems, no callus, or swollen stems, black stems Number of plants × (-2)

[0028] Grade 3: Stems are swollen, with callus, but not yet rooted Number of plants × (0)

[0029] Grade 4: There is callus, root occurs, and the root is less than 1mm Number of plants × (2)

[0030] Grade 5: There is callus, root occurs, the root is larger than 1mm, and the number is large Number of plants × (4)

[0033] Conclusion: IBA significantly affects the rooting of Taxus mandiensis cuttings. The best combination was NAA300mg/L, IBA300mg/L, and the cutting soaking time was 3h.

[0037] Grading Standard: Grade 1: No callus, stem browning

[0038] Grade 2: There is callus, the stem is not browned

[0039] Grade 3: 1-2 roots have emerged, and the root length is less than 0.3mm

[0040] Grade 4: good rooting, with 2-5 roots, root length less than 1cm,

[0041] Grade 5: The roots are many and long, and the root length is greater than 1cm

[0042] The results showed that the effect of drying the sodium salts of NAA and IBA was better than that of microwave drying; the addition of vitamin C to the rooting powder had no obvious effect.
