Problems solved by technology

[0003] Due to the deep dormancy of the seeds of the hammer tree and the slow speed of sexual reproduction, the asexual propagation methods currently include tissue culture and cuttings, but the cost of tissue culture is high and the rooting rate of cuttings is not high

Embodiment 1

[0033] The effect of embodiment 1 different hormone treatment cuttings on rooting traits

[0034] The experimental site is located in the Niushou Mountain Forest Farm, the practice base of Nanjing Forestry University. The cutting seedbed is rectangular in the north-south direction, with sufficient light, 6m long and 0.80m wide, and is surrounded by bricks and cement. The bottom of the pond is 20cm long, 10cm wide and 5cm thick. Solid square bricks to increase the air permeability and water permeability of the slotting bed; then spread 30-40cm thick perlite on it, the perlite has good air permeability, moderate water content, and has the function of heat preservation, keeping the temperature of the entire seedbed at 25-35°C, The humidity is 85%-90%. It is also equipped with an automatic intermittent spraying device, and each slotting bed is equipped with 6 nozzles, which completely cover the entire seedbed when spraying. Spray the perlite with 0.3% potassium permanganate befor...

Embodiment 2

[0048] The influence of the hormone treatment cuttings of embodiment 2 different concentrations on rooting traits

[0049] The cuttage propagation condition of the scale hammer tree is the same as that of Example 1, and the difference is to keep the 20-30°C of the whole seedbed, and the humidity is 90%-95%; (0, 50, 100, 150, 200mg·L -1 ) were soaked for 4h respectively.

[0050] The result of hardwood cuttings is as shown in the following table 3

[0051] Table 3 Effects of different concentrations of ABT on rooting traits of hardwood cuttings

[0052]

[0053] It can be found from Table 3 that the cuttings from the 2-year-old mother tree were treated with 150mg L of ABT -1 The rooting traits after treatment were generally high, and the rooting rate was 31.02%, which was not different from other concentration treatments; the number of primary lateral roots was 14.79 / root, and the difference among treatments was extremely significant. The rooting traits of the cuttings f...

Embodiment 3

[0058] The influence of embodiment 3 different soaking time on cuttings rooting

[0059] The cutting propagating condition of the scale hammer tree is the same as that of Example 1, and the difference is to keep the 30-35°C of the whole seedbed, and the humidity is 90%-95%; -1 The rooting powder No. ABT6 was soaked for 0, 1, 2, 3, 4 hours respectively.

[0060] Use 200mg·L -1 Table 5 shows the index values ​​of the rooting traits of the cuttings of the hard branch cuttings of Scale Hammer tree after soaking them for different periods of time.

[0061] Table 5 200mg·L of different soaking time -1 Effects of ABT Treatment on Rooting Traits of Hardwood Cuttings

[0062]

[0063] As can be seen from Table 5, the 200mg·L of different soaking time -1 ABT treatment affected the rooting traits of hardwood cuttings to a certain extent, and the responses were different with different ages of mother trees. The cuttings of the 2-year-old mother tree have a better effect after soak...

Abstract

The invention discloses a cutting propagation method of sinojackia xylocarpa. The method comprises the following steps: (1) selecting sinojackia xylocarpa seedlings of 2-10 years, cutting out sinojackia xylocarpa branches of 5-10 cm from the sinojackia xylocarpa seedlings, soaking and disinfecting to prepare cuttings; (2) cutting the cuttings prepared in the step (1) into a substrate of a seedbed, wherein the temperature of the seedbed is 20-35 DEG C, and the humidity is 85-95 percent; (3) after cutting the cuttings into the seedbed, thoroughly watering once, and keeping the leaf surfaces of the cuttings in a moist state in one month after cutting, until callus tissues are produced. According to the cutting propagation method of the sinojackia xylocarpa, the branchs of the sinojackia xylocarpa of 2-10 years are selected as the cuttings, and the temperature of the seedbed is controlled to be 20-35 DEG C and the humidity is controlled to be 85-95 percent, so that the survival rate of the cuttings is improved and a theoretical foundation is laid for root growing rate of cuttings.

Description

technical field [0001] The invention belongs to the technical field of arboriculture, and relates to a cutting propagation method, in particular to a cutting propagation method of a weighing tree. Background technique [0002] The scale hammer tree grows slowly, the plant is not high, and although there are many fruits, there are erosion and hollow phenomena in a large number of seeds, and the seeds have the habit of deep dormancy, and the natural germination rate is very low, so the seed reproduction is not easy; in addition, due to Habitat fragmentation, habitat destruction, and its own seed physiological characteristics have seriously disturbed the regeneration of this plant population, and the population size has declined sharply, making it endangered or threatened. The wild scale hammer tree is hard to find in Nanjing. Therefore, although the scale hammer tree is unique to Jiangsu, the wild plants may have disappeared. At present, only some botanical gardens and arbore...
