Embodiment 1

[0038] A method for raising seedlings by root tiller cuttings of Acacia blackwood, comprising the following steps:

[0039] Step 1: Level the forest land, loosen the soil, and set up a drainage ditch; cover the seedbed with a sunshade net with a light transmittance of 40%;

[0040] Step 2: laying a seedbed on the leveled forest land, and laying a matrix on the seedbed; the matrix is ​​formed by mixing fine sand and yellow core soil in a mass ratio of 2:1;

[0041] Step 3: Cut the semi-lignified spikes from the roots of the mother plant of Acacia blackwood into 2cm long cutting strips, and cut them on the seedbed at an angle of 40-60 degrees; spray water on the seedbed every 5 minutes to make semi-lignified Acacia blackwood spike moistening;

[0042] Step 4: Trim the cuttage of Acacia blackwood in the seedbed, and keep 2 plump buds;

[0043] Step 5: Spray the exogenous hormone GGR6 to the Acacia blackwood cut in the seedbed, the concentration of the GGR6 is 240mg / L, and the t...

Embodiment 2

[0046] Step 1: Level the forest land, loosen the soil, and set up a drainage ditch; cover the seedbed with a sunshade net with a light transmittance of 70%;

[0047] Step 2: laying a seedbed on the leveled forest land, and laying a matrix on the seedbed; the matrix is ​​formed by mixing fine sand and yellow core soil in a mass ratio of 2:1;

[0048] Step 3: Cut the semi-lignified spikes from the roots of the mother plant of Acacia blackwood into 4cm long cutting strips, and cut them on the seedbed at an angle of 40-60 degrees; spray water on the seedbed every 5 minutes to make semi-lignified Acacia blackwood spike moistening;

[0049] Step 4: Trim the cuttage of Acacia blackwood in the seedbed, and keep 3 full buds;

[0050] Step 5: Spray the exogenous hormone GGR6 to the Acacia blackwood cut in the seedbed, the concentration of the GGR6 is 260mg / L, and the treatment time of the GGR6 is 70s;

[0051]Step 6: Fertilize the seedbed with Acacia blackwood cuttings, and the amount...

Embodiment 3

[0053] Step 1: Level the forest land, loosen the soil, and set up drainage ditches; cover the sunshade net with 55% light transmittance above the seedbed;

[0054] Step 2: laying a seedbed on the leveled forest land, and laying a matrix on the seedbed; the matrix is ​​formed by mixing fine sand and yellow core soil in a mass ratio of 2:1;

[0055] Step 3: Cut the semi-lignified spikes of the root tiller of Acacia blackwood mother plant into 3cm long cutting strips, and cut them on the seedbed with an inclination of 50 degrees; spray water on the seedbed every 5 minutes to make the semi-lignified spikes of Acacia blackwood moisten

[0056] Step 4: Prune the Acacia blackwood cuttings in the seedbed, and keep 2.5 plump buds;

[0057] Step 5: Spray the exogenous hormone GGR6 to the Acacia blackwood cut in the seedbed, the concentration of the GGR6 is 250mg / L, and the treatment time of the GGR6 is 60s;

[0058] Step 6: Fertilize the seedbed with Acacia blackwood cuttings, and the...

Abstract

The invention relates to the field of seedling planting, in particular to an acacia melanoxylon root sucker cutting seedling-raising method. The internal structure of a semi-lignified scion is more stable and mature than that of a scion of an epicormic branch, the resistance of the internal structure of the semi-lignified scion is better than that of the scion of the epicormic branch, and the resistance of acacia melanoxylon is high, so that the scion requires more time to be in contact with an exogenous hormone for absorbing the exogenous hormone fully; in the selection of type and concentration of the exogenous hormone, the exogenous hormone with higher concentration has an inhibiting effect on the rooting rate of the acacia melanoxylon in consideration of the characteristics of high resistance of the acacia melanoxylon; the GGR6 with the concentration of 240 to 260 mg / L is taken as the exogenous hormone for acacia melanoxylon root sucker cutting seedling-raising, so that a semi-lignified scion of the acacia melanoxylon can be induced to bring forth new roots quickly, and an effect of accelerating the division and growth of cells is achieved; therefore, the effect of improving the survival rate of the acacia melanoxylon root sucker cutting seedling-raising is achieved.

Description

technical field [0001] The invention relates to the field of planting seedlings, in particular to a method for growing seedlings by root tiller cuttings of Acacia blackwood. Background technique [0002] Acacia melanoxylon is a strong positive tree species, native to southern Australia, and is one of the tallest acacia trees. It is light-loving, drought-resistant, barren-resistant, long-lived, and can withstand low temperatures of -6°C. Shallow root type, well-developed lateral roots, grows well on acidic soil above 30cm in soil layer. The distribution of Acacia blackwood extends from Queensland in eastern Australia through South Australia to Tasmania in the south, about 16-43° south latitude, mainly in the warm temperate zone. Vertical distribution from near sea level up to 1500m. The average temperature of the coldest month in the area is 1-10°C, and there may be 40 days of heavy frost in a year. The annual rainfall is 750-1500m. This tree species is suitable for growi...
