And a reinforcing frame 2 is welded every 70-80 cm to play a supporting role. On the foundation framework of the seedling raising bed, a layer of supporting net 3 with coarse steel wires criss-cross can be welded, and the gap interval is about 10 cm and is used for receiving seedling raising pots which are closely arranged above.
The breeding method of the sophora moorcroftiana air root cutting seedling raising device comprises the following steps:
s1, selecting seeds: spreading pods on the ground, beating or rolling to drop seeds, putting the seeds into clear water, rapidly and uniformly stirring, rinsing, airing the rinsed seeds until the seeds are completely dried, and selecting the seeds with full particles and glossy seed coats for later use;
s2, acid etching treatment: acid etching the seeds in the step S1 with sulfuric acid with the concentration of 98%, submerging 2-5cm on the surfaces of the seeds with sulfuric acid, continuously stirring with a glass rod, acid etching for 2 hours, and repeatedly cleaning with clear water for 6-8 times until the surfaces of the seeds are washed cleanly;

s4, accelerating germination: spreading the sterilized wet non-woven fabric with thickness of 1-1.5cm on a culture dish, spreading the swelled seeds on the culture dish, covering the wet non-woven fabric, covering the culture dish with a plastic film for moisturizing, placing the culture dish in a dark constant temperature incubator at 25-30 ℃ for sprouting, observing the sprouting condition of the seeds every day, and moisturizing the wet non-woven fabric covered on the culture dish by spraying to maintain the humidity;
s5, root promotion: after the seeds in the step S4 germinate, culturing for 2-3 days under full illumination when radicle stretches to 1-3cm, and completing root promotion when cotyledon turns green to obtain seedlings for later use;
s6, seedling cultivation: transplanting the seedlings in the step S5 into seedling raising pots, exposing green sub-leaves on the surfaces of matrixes in the seedling raising pots, orderly stacking the seedling raising pots on a seedling raising bed, and fully spraying and watering; wherein the substrate in the seedling raising basin is perlite, water-washed sand, turfy soil and water-retaining agent, the volume ratio of the perlite, the water-washed sand and the turfy soil is 1:1:1, and the water-retaining agent is 1-3 per mill of the total volume of the substrate; 2-3 plants of seedlings transplanted in each seedling raising basin, wherein the height of the matrix in the seedling raising basin is kept at 33-37cm in the seedling raising process;
s7, ground transplanting: researches show that the rhizome ratio of Sophora japonica is about 3:1, when the stems of seedlings in the seedling raising basin grow to 12-13.5cm, the length of 70-80% of lateral roots can reach 33-37cm, the lateral roots already grow to the supporting net 3, the root tips are necrotic after contacting with dry air, further more lateral roots are promoted, and at the moment, ground transplanting can be carried out.
In the seedling raising process, when the roots of seedlings in the seedling raising basin grow to the supporting net 3, the root tips are necrotic after contacting with dry air, so that the growth of lateral roots is promoted.
Compared with the conventional root-taking and soil-entering seedling method, the breeding method does not need to cut roots manually, reduces the damage to root systems, and improves the survival rate of Sophora japonica. Experiments show that the survival rate of the sophora moorcroftiana cultivated by the breeding method is 83-90%, the survival rate of the sophora moorcroftiana cultivated by the conventional rooting and soil-entering type seedling method is 78-85%, and the survival rate of the sophora moorcroftiana cultivated by the breeding method is greatly improved.
Therefore, the air root cutting and seedling raising device for the Sophora japonica and the breeding method adopting the structure can achieve the cultivation environment of air root cutting, and compared with the conventional root taking and soil entering type seedling raising method, the breeding method can effectively reduce the damage to root systems in the ground transplanting process of Sophora japonica, thereby improving the survival rate of forestation.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention and not for limiting it, and although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that: the technical scheme of the invention can be modified or replaced by the same, and the modified technical scheme cannot deviate from the spirit and scope of the technical scheme of the invention.
