Abstract: The present disclosure discloses a walking power control system for wolfberry picking, including a frame, a turntable, rotating rods, first gears, second gear, gear racks, supporting rods, hydraulic motors, a front traveling wheel, a left traveling wheel and a right traveling wheel. In the present disclosure, hydraulic motors rotate to drives three traveling wheels to rotate, thereby driving the frame to move, when it is necessary to turn, a turntable is rotated, the turntable rotates to drive two first gears to rotate, and the two first gears rotate to drive the supporting rods to rotate, thereby driving the left traveling wheel and the right traveling wheel to rotate, so that the traveling direction of the frame is changed. The picking speed of wolfberries is greatly improved, thereby improving the working efficiency and saving a lot of human resources.

Abstract: Disclosed in the present invention is a trnL-trnF barcode and a DNA barcoding-based method for rapid identification of Lycium chinensis, relating to the technical field of identification of Lycium chinensis varieties. A Lycium chinensis phylogenetic tree is constructed based on the present DNA barcodes, and used in the study of the intraspecific and interspecific phylogeny of Lycium chinensis. The present invention further provides trnL-trnF barcode database of Lycium chinensis samples. By performing sequence alignment of trnL-trnF sequence of the sample to be identified and the trnL-trnF barcode database of Lycium chinensis samples, the Lycium chinensis varieties can be effectively identified and their interspecific relationship can be determined, providing an effective basis for the classification and identification of Lycium chinensis varieties.

Abstract: The invention belongs to the technical field of species identification of Lycium chinensis, specially relating to a DNA barcode for identifying Lycium chinensis species and an identification method therefor. The DNA barcorde provide by the present invention can be applied to building a phylogenetic tree to be used for studying intra-species and inter-species phylogeny of Lycium chinensis, providing an effective basis for identification, classification and phylogenetic study of Lycium chinensis. The invention also provides a trnG-trnS barcode database, to effectively identify the species of the Lychium chinensis and determine the interspecies relationship of Lycium chinensis, thereby providing an effective basis for the species of Lycium chinensis.
