The application of broccoli genes BoSULTR1;1 and BoSULTR1;2 in improving plant stress resistance belongs to the technical field of plant genetic engineering. In order to solve the technical problem of how to improve the stress resistance of broccoli plants, the application provides the broccoli genes BoSULTR1;1 and BoSULTR1;2, and the application uses an expression vector or a recombinant bacterium overexpressing BoSULTR1;1 and BoSULTR1;2 genes to prepare a transgenic broccoli plant. The stress resistance related detection results prove that the BoSULTR1;1 and BoSULTR1;2 genes have the ability to improve the resistance of the transgenic broccoli plant to cotton bollworm, pathogenic bacteria and drought. The transgenic material obtained by the application has important theoretical significance and practical value for accelerating the breeding process of stress-resistant plants and improving the breeding efficiency.

The utility model discloses a low noise cabinet type centrifugal fan relates to centrifugal fan field, including cabinet body and fan body, wherein fan body is located inside the cabinet body, the bottom of fan body is provided with the energy absorption box in the cabinet body, and the inner wall of cabinet is provided with also sound absorption cotton, wherein the inside elastic sliding of energy absorption box is provided with the placing plate, one side of energy absorption box in the cabinet is provided with the shower nozzle that cooperates with placing plate. The utility model placing plate is buffered to it under the action of elastic component, and the vibration energy generated in its working process is absorbed, at the same time, the sound absorption cotton of cabinet inner wall is cooperated, so that the noise in the cabinet is effectively reduced, the gas is discharged through the shower nozzle, thereby can effectively reduce the dust impurity of outside to invade the inside of fan body, and the service life of fan body itself is improved.

The utility model discloses a touch screen conference table all-in-one machine with an adjustable screen angle, which relates to the field of conference table all-in-one machines and comprises a table body and a fixing plate, a driving component is arranged at the bottom of the fixing plate, a threaded rod is connected to the output end of the driving component, and a lifting plate matched with the threaded rod is slidably arranged on the inner wall of the fixing plate. A display screen body is arranged on the lifting plate in a sliding mode, a lifting groove for the lifting plate to slide is formed in the table body, and a cleaning assembly matched with the threaded rod is rotationally arranged in the lifting groove. The display screen slides to the top of the table body under the action of the lifting plate, the display screen is reset after follow-up use is completed, the occupied area of the display screen body is greatly reduced in the process, the display screen body lifted to the top of the table body is obliquely arranged under the cooperation of the special-shaped sliding grooves and the guide columns, and the display screen body is prevented from being damaged. And meanwhile, the cleaning assembly rotates quickly, so that dust on the display screen body is cleaned.

The utility model provides an automatic picking and shaking machine for facility substrate blueberries, which comprises a material receiving mechanism and a vibrating mechanism, and the material receiving mechanism comprises two material receiving hoppers which are oppositely arranged left and right; the vibration mechanism comprises a supporting rod, a vibration power assembly and a first fork piece, the supporting rod is vertically installed on one of the material receiving hoppers, the vibration power assembly is fixed to the upper portion of the supporting rod, the first fork piece comprises at least eight first fork needles arranged side by side, the first fork needles are arranged in the left-right direction, and the first fork needles are arranged in the left-right direction. The same ends of all the first fork needles are fixedly connected, the other ends of the first fork needles are suspended, the output end of the vibration power assembly is fixedly connected with one ends of the first fork needles, and the vibration power assembly drives the first fork pieces to conduct reciprocating linear vibration. By means of a reciprocating vibration mode, mature blueberry fruits can be picked, petals after fruit setting can be shaken off, harm of gray mold is reduced, and blueberry branches and trunks cannot be damaged.
