The invention discloses a method for screening high-efficiency varieties of double-cropping super rice with water and fertilizer synergy, which includes screening seeds, treating nitrogen application rate as the main area, and split-plot irrigation method for split-plot test, calculating average yield, data processing, and variety screening And other steps can quickly, conveniently, efficiently, and low-cost screen out varieties with high water-fertilizer synergy in double-cropping super rice, which solves the problems of single screening elements and unscientific screening in existing screening research.

The invention discloses a chromatographic column decorated by lipid rafts. The chromatographic column is a silica gel chromatographic column which is decorated with the lipid rafts on the surface. A TrkA lipid raft-sillica gel stationary phase chromatographic system is built firstly. Stationary phase can be combined with medicinal specificity of tyrosine kinase receptors as a target spot, and then reservation is produced, but non-reservation behavior is not existed in the TrkA lipid raft-sillica gel chromatographic column of the tyrosine kinase target spot medicines. Lipid raft-sillica gel chromatograph which is rich in TrkA receptors is a novel medicine screening model which has a living being affiliation character and is capable of selective recognition medicines, wherein the medicines are reacted with the TrkA receptors. The chromatographic system is different from the traditional chromatographic system and has double characters of chromatograph separation and activity recognition. Therefore, the chromatographic system can be used for guide medicine screening study where the TrkA receptors served as drones. The chromatographic column decorated by the lipid rafts is used through different time and different moving phases, and the TrkA lipid raft-sillica gel stationary phase chromatographic system is proved stable. The chromatographic column is good in repeatability, long in service life and has good application prospects. The invention discloses a manufacturing method of the chromatographic column decorated by the lipid rafts.

The invention relates to a new vascular tissue generation method. The method comprises, removing thoracic aorta, heart tissue, liver tissue, spleen tissue, lung tissue, kidney tissue and colon tissue from a mouse or a rat under a sterile condition; carrying out a combination of the removed tissues and the culture plate to generate the new vascular tissues respectively corresponding to the aorta, the heart tissue, the liver tissue, the spleen tissue, the lung tissue, the kidney tissue and the colon tissue. With the method provided by the present invention, disadvantages of cumbersome quantity and not high survival rate are overcome; a simple and convenient model of the new vascular tissue generating is established, wherein the model can be widely used; the method further can be applicable for screening studies of the tumor angiogenesis inhibitor.

The invention provides a specific primer, kit and identification method for identifying donkey-derived components. A large number of primers are designed based on the CYT B and COX-1 genes of donkeys, and a large number of primers are screened and studied. Specific primers, using the above primers to identify donkey-derived components in the test mixture, can accurately separate donkeys from other confounding products, and the PCR amplification product is only 50-150bp, with a small molecular weight, ensuring its A large number of donkey-derived components in the mixture are identified in a short period of time, and the identification results are accurate, stable, reliable, and highly sensitive.

The present invention provides a method for quantitative calculation of paleo-depth for lacustrine deposition, the method for quantitative calculation of paleo-depth for lacustrine deposition includes: step 1, screening lakes similar to the research area; step 2, for the screened lakes, establishing Quantitative relationship between lake bottom sediment TOC and water depth; step 3, conduct mudstone TOC test for the research area, and count the stratum thickness of the target layer; step 4, establish the quantitative relationship between ancient water depth data and stratum thickness; and step 5, draw ancient Plane distribution of water depth. The paleo-depth quantitative calculation method for lacustrine sediments further improves the means of paleo-depth restoration, and provides new research ideas and technical means for the study of paleo-lake sedimentary evolution process and the prediction of multi-type lacustrine sand bodies.
