The invention discloses a method for breeding early doubled haploids of maize by using yellow-green seedling markers, and belongs to the field of breeding methods. The invention also discloses a method for identifying the induced haploid by using the yellow-green shoot marker and a method for cultivating the haploid induction line with the yellow-green shoot marker. The present invention uses the yellow-green seedling traits controlled by the single dominant gene Yg3 gene to realize accurate identification and screening of induced haploids at the seedling stage. Simple, with obvious distinguishing features, accurate and reliable identification of haploid, early doubled haploid, and pseudo-haploid can be made at the seedling stage, especially for the identification of doubled haploid, avoiding it as a pseudo-haploid Elimination can achieve one-step line formation; the use of yellow-green seedling markers has high identification efficiency, which greatly saves manpower and material resources, can be used to expand the size of the induced population, and can realize mechanized identification of seedlings, greatly improving breeding efficiency.

The invention relates to a nondestructive detection method for identifying F1 seed true / false between species of peanut with a high oleic acid content and peanut a with normal oleic acid content. The method comprises the following steps: harvesting all F1 seeds, which are obtained by hybridizing species of peanut with a high oleic acid content and peanut a with normal oleic acid content and seeds of female selfing under same planting conditions; individually measuring the oleic acid contents of single granules of mother parent and F1 by a near infrared spectrum technology; when the female parent is peanut with a common oleic acid content, calculating the ratio of F1 seeds that contains a oleic acid content higher than that of female parent, if the ratio is more than 10%, judging the F1 seeds are true hybrids, if the ratio is less than 10%, judging the F1 seeds are false hybrids; when the female parent is peanut with a high oleic acid content, calculating the ratio of F1 seeds that contains a oleic acid content lower than that of female parent, if the ratio is more than 20%, judging the F1 seeds are true hybrids, and if the ratio is less than 20%, judging the F1 seeds are false hybrids. The provided method has the advantages that the seed are not damaged, no pretreatment is needed, the method is pollution-free, fast, and convenient, the detection speed is quick; the detection only needs a near-infrared spectrum analyzer, and the operation is convenient and quick, and is easy to apply.

The invention relates to an automatic detection device and method for an isolating switch state based on image processing. The device includes a camera module, a processing terminal and a control terminal. The camera module is connected to the processing terminal. The camera module includes a housing and a camera ball that is rotated in the housing. A drive module is arranged in the housing, and the control terminal is connected to the drive module. , and the driving module is linked with the camera ball. The detection method includes decomposing the camera video to obtain several pictures; preprocessing the pictures to obtain characteristic pictures highlighting the isolating switch; detecting and tracking the isolating switch; judging the state of the isolating switch according to the tracking situation. The invention automatically detects the state of the isolating switch, replaces the operator's on-site confirmation, reduces invalid labor, and improves efficiency and benefit. At the same time, the camera module can be rotated and adjusted, so that the camera angle can be flexibly adjusted to obtain better images for subsequent processing.

The invention discloses an axle storage rack. The axle storage rack comprises a storage rack body, a first storage position and a second storage position, wherein the first storage position and the second storage position are arranged on the storage rack body; a plurality of first slots are formed in the first storage position; a plurality of second slots are formed in the second storage position; a first pressure plate and a first spring are respectively arranged on two sides of each first slot; each first spring is connected between the corresponding first slot and the corresponding first pressure plate; a second pressure plate and a second spring are respectively arranged on two sides of each second slot; and each second spring is connected between the corresponding second slot and the corresponding second pressure plate. An automobile axle is placed in one of the slots of the storage rack so that the automobile axle is fixed; under the effects of the springs and the pressure plates, axles are placed quite firmly and cannot slip out easily, the safety is high, knocking, collision, damage, dirty and mess of the axles in a conveying process can be prevented, the quality of the automobile axles is guaranteed, meanwhile, the automobile axles are convenient to take, ineffectual work is reduced, and work efficiency is improved.

The invention relates to a disposable venous transfusion one-way check device. According to the venous transfusion one-way check device, a one-way check unit which is integrated with a capillary tube is arranged at the connecting end of the capillary tube and an infusion tube of a disposable venous transfusion device, so that liquid medicine reflux in veins when a patient sits down, stands up or even walks after or during the transfusion process. The venous transfusion one-way check device changes the structure of the disposable transfusion device little, is simple in structure, low in cost and applicable to industrial production, does not change the working habit of medical care personnel, facilitates popularization and application, improves the working efficiency, saves puncture needles and reliefs patients from pain.
