The invention discloses a cyclocarya paliurus breeding and germinating method and belongs to the field of tree reproduction. The cyclocarya paliurus breeding and germinating method is characterized by comprising the following steps: (1) carrying out alkalization seed immersing treatment; (2) carrying out vibration and decompression nitrogen-enriching treatment; and (3) carrying out germination accelerating treatment. Compared with the prior art, the method disclosed by the invention can promote the germination of cyclocarya paliurus seeds to obtain the relatively high germination rate; and under a relatively low temperature environment, the relatively high survival rate of seedlings can be obtained.

The invention discloses a pipe network system used for solving the problem of frozen soil in a tailing pond, and a construction method thereof. The pipe network system comprises horizontal ventilation pipes and vertical connection pipes, wherein the end heads of the horizontal ventilation pipes extend out of the tailing pond and communicate with the atmosphere; the middle sections of the horizontal ventilation pipes communicate with a flood draining facility of the tailing pond through the vertical connection pipes; and the horizontal ventilation pipes on the same elevation surface can be of a pipe network structure. The construction method of the pipe network system comprises the following steps: starting to accumulate tailings and pre-embedding the vertical connection pipes after the initial dam of the tailing pond and the flood draining facility are constructed; pre-embedding the first-stage horizontal ventilation pipes after the accumulation elevation of the tailings is higher than the elevation of the dam crest of the initial dam, wherein inclined connection pipes can be selectively pre-embedded; and increasing the elevation and the number of the vertical connection pipes, the horizontal ventilation pipes and the inclined connection pipes stage by stage with the rising of the accumulation elevation of the tailings until laying is completed. The pipe network system disclosed by the invention is simple in structure, convenient to construct and capable of efficiently solving the problem of the frozen soil in the tailing pond, and can further be used as a draining and seepage channel in the case of a high precipitation amount.

The invention discloses a method for facilitating germination of sassafras seeds, and belongs to the field of tree breeding. The method is characterized by comprising the following steps that (1) alkalization is conducted on the seeds, and the seeds are soaked; (2) vibration, decompression and nitrogen-rich processing are conducted; (3) accelerating germination is conducted. Compared with the prior art, the method for facilitating the germination of the sassafras seeds can facilitate the germination of the sassafras seeds, obtain the higher germination rate, and obtain the higher seedling survival rate at a relatively low temperature.
