Example 1
Construction of a full-automatic spray cutting pool: in a nursery garden of a garden science research institute in Wuhan City, selecting a place with sufficient illumination, flat terrain, good ventilation and convenient drainage to build a cuttage pool, firstly spreading 1 layer of bricks on the ground, and enclosing the cuttage pool with the diameter of 15 meters by 10 layers of bricks, and erecting an automatic spraying system controlled by time at a height of 1 meter above the middle of the cuttage pool in the length direction; the upper part is not laid with a sunshade net, which is a full light condition.
Cutting medium: paving wood yellow sand in the built cuttage pool: peat: perlite 5: 3: 2 (volume ratio) of the uniformly mixed matrix, and the paving thickness is 20 cm. Spraying and disinfecting the cutting matrix by using 600 times of potassium permanganate solution, covering for 3 days by using a plastic film, killing germs by using poison, uncovering the film for 3 days, and cutting after the medicine is volatilized. The cutting is watered thoroughly for 2 times before cutting to make the matrix absorb enough water.
Cutting collection and cutting preparation: when dew is not dry in the morning of 5 and 7 months in 2018, 1-year-old thick branches of the silver wood alkali-resistant elite tree are selected for collection, and the branches are vertically inserted into a bucket, and water with the depth of 10cm is filled in the bucket. Collecting 500 branches, then taking the branches indoors for preparing the cutting slips, keeping the length of the cutting slips to be 10-12cm, leaving 1-2 leaves, trimming a lower cutting opening into 45-degree bevels, cutting 1 branch into 2-3 cutting slips, and finally obtaining 1200 cutting slips for cutting.
Hormone treatment and cuttage: before cuttage, 0-4cm of the base of the cutting shoot is quickly dipped for 10 seconds by using a mixed solution of 2000ppm of naphthylacetic acid and 500ppm of 2, 4-dichlorophenoxyacetic acid, and the cutting shoot is quickly taken out and cuttage is carried out, wherein the cuttage depth is 5-6cm, and the density plant row spacing is 8cm multiplied by 10 cm. Watering with a watering can after the cutting is finished, so that the cutting is tightly contacted with the substrate. Spraying 800 times of potassium permanganate solution once after cuttage is finished.
And (3) maintenance management after cuttage: the rooting time of the silver wood alkali-resistant fine variety cutting is 40-45 days, and the cutting shoot maintenance condition is full exposure. In the first 40 days after cuttage, the time control water spraying requirement is as follows: spraying for 20 seconds every 30 minutes under the sunny condition; spraying every 60 minutes for 20 seconds in cloudy days. After 45 days, the time control water spraying requirements are as follows: spraying for 10 seconds every 30 minutes under the sunny condition; spraying every 60 minutes for 10 seconds in cloudy days.
And (3) management and transplantation after rooting: after the 35 th day of cutting, 50% of the cuttings had rooted and began to leaf. After the cutting shoots and leaves, leaf surface dressing is carried out, and 0.2% urea is sprayed for 80 days of cutting. The cuttage seedlings are planted in the cuttage pool in winter and are transplanted in the spring of the next year. And performing rooting investigation and transplanting in 2019 and 3 months, wherein the rooting rate is 76%, the rooting condition of 100 cutting seedlings is investigated, and the average rooting number of each plant is 5.12, the average root length is 14.36cm, and the root thickness is 3.16 cm. During transplanting, the roots of the plants are provided with a small amount of yellow sand, peat soil and perlite on a cutting bed, so that the rooting and survival are facilitated, and the transplanting survival rate is 96% in a survey on 6 months and 1 day in 2019.
The current stage of the silver wood is mainly seed breeding, but the seed breeding is influenced by environment and hybridization, and the excellent properties of a mother plant are difficult to ensure, so the excellent characteristics of the original variety of the silver wood can be ensured by cutting propagation, and meanwhile, the propagation material is sufficient and is not limited by seed resources.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
