The invention provides application of nitraria tangutorum bobr extract in preparation of products for regulating glycolipid metabolism disorder, and relates to the technical field of plant extract application. The nitraria macrocarpa extract is a composition rich in alkaloid and flavonoid compounds, wherein the sum of the content of total alkaloid and the content of total flavonoids is not lower than 85% of the total weight of the extract. The extract is prepared through the processes of fresh fruit juicing, alcohol precipitation impurity removal and AB-8 macroporous resin gradient elution. Experiments show that the extract can significantly reduce fasting blood glucose of type 2 diabetes mice induced by high-fat and high-sugar diet combined with STZ, improve sugar tolerance and insulin resistance, and synchronously regulate the blood fat level, and shows an excellent glucose and lipid metabolism synergistic improvement effect. The extract disclosed by the invention provides a choice for developing a safe and effective glycolipid metabolism regulator.

A method for planting N. tangutorum in summer, includes: seedling cultivation: customizing a square seedling plot on a flat surface, mixing sandy soil, loam, and farmyard manure in a ratio of 3:6:1, sowing N. tangutorum seeds in non-woven bags at a depth of 2 centimeters, and maintaining a humidity; seedling lifting: gently removing, when seedlings grow to a height of 10-20 centimeters, the seedlings along with the non-woven bags to ensure the integrity; transportation: placing the seedlings into plastic transport boxes and trimming stems to ensure tight arrangement; transplanting: digging planting holes, placing nutrient bowl seedlings into the planting holes respectively, and back filling and firming down soil; planting: planting with a row spacing of 3 meters and a plant spacing of 1 meter, and then watering thoroughly for settling-in root; shade net installation: installing a shade net on each N. tangutorum seedling; and irrigation: performing watering every three days.

The invention belongs to the technical field of plant gene molecular markers, and particularly relates to a DNA bar code for identifying nitraria tangutorum and nitraria sibirica and application of the DNA bar code. The DNA bar code for identifying the nitraria tangutorum and the nitraria sibirica comprises a specific variation site combination located in an internal transcriptional spacer (ITS), a site matrix with species diagnosability is formed, the sites have stable species specificity, the nitraria tangutorum and the nitraria sibirica can be rapidly identified by detecting a nucleotide sequence of an ITS2 region of a sample, and the DNA bar code for identifying the nitraria tangutorum and the nitraria sibirica can be used for identifying the nitraria tangutorum and the nitraria sibirica. Particularly, the identification accuracy is remarkably improved under the condition that morphological identification is not feasible or uncertain, so that collection, conservation and related scientific research work of germplasm resources are facilitated, and a convenient method is provided for germplasm identification and resource protection.

The invention relates to the technical field of nitraria davidii cultivation, in particular to a resource sharing type ecological planting device and method for interplanting forage grass under a nitraria davidii forest.The device comprises a self-propelled chassis, a T-shaped supporting arm is arranged at the front end of the self-propelled chassis, and one side of the short edge of the T-shaped supporting arm is fixedly connected with a cutting assembly used for cutting off nitraria davidii branches; a smashing assembly located below the cutting assembly and used for smashing nitraria tangutorum branches is arranged at the front end of the self-propelled chassis, the cutting assembly and the smashing assembly are in transmission through a chain, and the smashing assembly extends into the self-propelled chassis. And the inner side wall of the self-propelled chassis is fixedly connected with a driving motor. According to the device, continuous and automatic operation of branch cutting, smashing, seed sowing and fertilizer applying can be achieved in the same operation process, so that the planting efficiency is remarkably improved, the labor input is reduced, and the cyclic utilization rate of branch resources is increased.

This invention discloses a rapid propagation method for *Nitraria tangutorum* seedlings induced from leaves, belonging to the field of tissue culture. The method includes: rooting culture of explant leaves, with a rooting medium of 1 / 2 MS + 0.5 mg / L indolebutyric acid; proliferation culture, with a proliferation medium of MS + 2.0 mg / L 6-benzylaminopurine + 1.0 mg / L zeatin + 2.0 mg / L indolebutyric acid; and rooting culture, with a rooting medium of 1 / 3 MS + 2.0 mg / L indolebutyric acid. This invention achieves rapid propagation of *Nitraria tangutorum* under artificially controlled conditions using tissue culture (from explant culture to seedling rooting takes only 35-45 days). Compared with previous tissue culture methods, this invention eliminates the callus culture step, avoiding browning, vitrification, and contamination that occur in callus culture, thus significantly accelerating the seedling formation rate and greatly improving seedling quality.
