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 an application of a tobacco NtSnakin2 protein and / or NtSnakin2 gene in improvement of tolerance or accumulation of plants on heavy metal cadmium. By constructing a saccharomyces cerevisiae transgene over-expression vector of the NtSnakin2 gene, the NtSnakin2 gene is over expressed in yeasts, tolerance of the yeasts on the heavy metal cadmium can be improved, cadmium content in the yeasts is reduced, discharge of cadmium in the yeasts is promoted, and tolerance of the yeasts on hydrogen peroxide also can be improved as the gene is expressed in the yeasts. The NtSnakin2 gene can be applied to the fields such as engineering bacteria, genetic engineering breeding of plants aiming at change of cadmium content in the plants and microorganism and phytoremediation for environmental heavy metal cadmium pollution.

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 relates to a microorganism producing poly-γ-glutamic acid and its construction method and application. The poly-γ-glutamic acid-producing microorganism disclosed in the present invention is a microorganism overexpressing phospholipase C, the overexpression is the introduction of one or more copies of the phospholipase C coding gene and / or the replacement of the expression element of phospholipase C It is an expression element with higher activity. In the microorganism obtained by increasing the expression of phospholipase C, the yield of poly-γ-glutamic acid produced by fermentation is significantly improved. The invention provides a new strategy for improving the yield of poly-γ-glutamic acid produced by microbial fermentation and reducing the production cost.

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.

The present invention relates to aryl-substituted amide compounds of formula (I) and their preparation methods, pharmaceutical compositions containing them and their application in pharmacy, wherein Ar1, L1, M1, M2, L2 and Ar2 are as described herein definition.

The invention discloses a pipe network system for treating frozen soil of a tailings pond by combining a drainage facility and a construction method for the pipe network system. The pipe network system comprises water guide pipes, transverse drainage pipes and vertical communication pipes, wherein the end heads of the transverse drainage pipes extend out of the tailings pond to communicate with atmosphere; and the middle sections of the transverse drainage pipes communicate with a flood drainage facility of the tailings pond through the vertical communication pipes. The construction method for the pipe network system comprises the following steps of: starting to accumulate tailings and embedding the vertical communication pipes after a dam and the flood drainage facility are constructed at an initial stage of the tailings pond; embedding the first-grade water guide pipes and the transverse drainage pipes after accumulation elevation of the tailings is higher than dam top elevation of the dam at the initial stage, and selectively embedding inclined communication pipes; and increasing elevation and number of the water guide pipes, the vertical communication pipes, the transverse drainage pipes and the inclined communication pipes step by step with increase of accumulation elevation of the tailings until laying is completed. The pipe network system is simple in structure, is convenient to construct, is relatively low in cost, and can efficiently treat the frozen soil of the tailings pond.
