The coconut chaff and the perlite are washed before being prepared, and after the matrix is prepared, the coconut chaff and the perlite are put into a 10 x 10cm nutrition cup or a non-woven bag and put in a cutting seedbed for later use.
(4) Cutting the cutting slips: selecting healthy plants without diseases and insect pests as stock plants, shearing semi-lignified branches and terminal twigs (not lignified) with robust peripheries and full branches of the stock plants, shearing cutting slips by utilizing shearing, wherein the cut is required to be smooth, 1 knot is reserved on each slip, 0.8-1.2cm is reserved on the upper part of each knot, 4-5cm is reserved on the lower part of each knot, blades are removed from the semi-ligneous branch slips, 3-4cm is reserved on two blades of the twig slips, and the rest parts of the blades are sheared.
(5) Preparing a root promoting agent: 100-200 ppm of indolebutyric acid, 100-200 ppm of naphthylacetic acid, or 100-200 ppm of naphthylacetic acid and indolebutyric acid, wherein the naphthylacetic acid and the indolebutyric acid are mixed according to the mass ratio of 1:1, and the concentration is 100-200 ppm.
(6) And (3) cutting treatment: and (3) soaking the cutting slips in the step (4) in 800 times of thiophanate methyl for 10min, fishing out the cutting slips, draining water, and then placing the cutting slips in the step (5) of dipping the cutting slips in the rooting agent for 10-20s at medium speed.
(7) Cuttage: and (3) pricking a cave in the substrate by selecting bamboos with the same thickness as the cutting shoots, inserting the cutting shoots processed in the step (6) into the cave for 3-4cm, and lightly compacting the substrate on the periphery.
(8) Managing after the insertion: after the cutting slips are inserted into the matrix, watering once for permeating water, then manufacturing (2) the small arched shed, covering a film, compacting and moisturizing the periphery, covering the film with a shading net with the shading rate of 50%, and keeping the humidity in the small arched shed to be more than 85%. When the temperature is higher than 33 ℃, two ends of the small arched shed are uncovered for ventilation; when the surface of the substrate is whitish, the film is uncovered and water is sprayed, the water is sprayed to wet the surface of the substrate, and the substrate is kept moist and breathable and is not prone to water accumulation.
(9) Training and transplanting: after 40-60 days of cuttage, uncovering a sunshade net with a shading rate of 50%, opening two films at two ends of a small arched shed, hardening seedlings for 3-4 days, uncovering the small arched shed film, hardening the seedlings for 3-4 days, then before 10 am and after 4 pm, retracting the sunshade net at the top of the thin film shed, hardening the seedlings for 3-4 days, retracting the outer sunshade net all day long, receiving full-light hardening seedlings for 5-7 days, and transplanting to a pot.
Experimental example 1: influence of different rooting agents on single-node cutting effect of red bud flowers
Test materials:
1. the cutting is divided into: twig, semi-lignified branch of current year
2. A rooting agent: IBA (100ppm, 200ppm), NAA (100ppm, 200ppm), IBA + NAA (100ppm, 200ppm), CK (clean water)
3. Matrix: coconut husk: pearlite 2:1
The method is operated according to the single-node cutting rapid propagation method of the red bud flowers. And after 30d of cuttage, counting the germination percentage, double-bud percentage, single-bud percentage, rooting rate and bud length of each treated 45 cutting shoot. The germination percentage is the number of the cutting shoots of the sprouts/the total number of the cutting shoots multiplied by 100%, the percentage of the double buds (or the single buds) is the number of the cutting shoots of the double buds (or the single buds)/the total number of the cutting shoots multiplied by 100%, and the rooting percentage is the number of the rooting cutting shoots/the total number of the cutting shoots multiplied by 100%. Shoot length means that 10 shoots were sampled at random per group and the larger of the two shoots was selected for analysis. The results are shown in Table 1.
TABLE 1
The results show that: the influence of different rooting agents on different cuttings shows difference. Wherein, the rooting rate of the tender branches treated by IBA (100-200 ppm) and NAA + IBA (200ppm) reaches 84%, the double-bud rate of the tender branches treated by IBA (100ppm) and NAA + IBA (200ppm) reaches more than 37%, and the buds are long.
The double-bud rate of the current-year half wooden branches treated by NAA (100-200 ppm), IBA (100-200 ppm) and NAA + IBA (200ppm) is over 53 percent, the rooting rate of the current-year half wooden branches treated by IBA (100-200 ppm) and NAA + IBA (200ppm) is over 84 percent, and the double-bud percentage is over 53 percent. NAA + IBA (200ppm) treated semi-woody shoots achieved the best rooting rate and higher double shoot rate and shoot length.
