The invention discloses a rapid evaluation method of host caries risk based on Raman spectrum, and relates to the technical field of microbiological detection. Aiming at the problem that in the prior art, it is difficult to rapidly and quantitatively reflect the early metabolic activity of the oral flora, the method introduces a stable isotope signal through heavy water labeling to obtain single-cell Raman spectrum information of the oral flora, and evaluates the metabolic activity of the flora on the basis of a characteristic parameter C-D ratio reflecting the metabolic state of microorganisms in a Raman spectrum, so that the early metabolic activity of the oral flora can be rapidly and quantitatively reflected. Therefore, the judgment of the caries risk of the host is realized. The method comprises the steps of sample collection, flora growth and metabolism law research under different concentration heavy water labeling, and metabolic activity detection under different environmental conditions. By adopting the heavy water concentration of 40%, on the premise that flora growth is not obviously influenced, rapid characterization of metabolic activity can be realized in a short time, the resolution ratio of single cells is high, and disturbance is small. The method provides a new tool for early warning of caries and oral flora metabolism research, and has a wide application prospect.

This invention discloses a soil sampling cylinder, a soil sampler, and a soil sampling method, relating to the field of geological exploration technology. The invention includes a cutting blade, which is a hollow cylinder with a straight inner and outwardly inclined circular cutting edge at the front end, and a threaded connection at the rear end to a steel cylinder.

This utility model discloses a parasite control device for ostrich farming, belonging to the field of ostrich farming technology. The device includes a drone body and a parasite control mechanism. The parasite control mechanism includes a clamping mechanism installed at the bottom of the drone body. The clamping mechanism includes a base plate, and a shell is provided on the top of the base plate. Limiting claws are driven on both sides of the shell, and a drug spraying component is clamped between the two limiting claws. The drug spraying component includes a spray box, and a nozzle is connected to the bottom of the spray box. The nozzle is positioned corresponding to the ostrich. The drone body drives the drug spraying component to perform aerial operations, which can quickly cover a large farming area, significantly improving parasite control efficiency and saving labor costs. Compared with traditional manual spraying, the operating efficiency can be increased by 3-5 times.

The utility model relates to the technical field of chicken raising, and discloses a chicken raising feed trough capable of catching chickens, which comprises a channel bin, a feed plate is rotatably mounted below a chicken inlet end of the channel bin, a feed storage cavity used for placing feed is arranged at the top of the feed plate, and a rotary driving component used for driving the feed storage cavity to rotate is mounted on one side of the channel bin. A moving-out groove allowing the material storage cavity to penetrate through is formed in the side, close to the rotary driving assembly, of the channel bin. According to the chicken raising trough capable of catching the chickens, the instinctive tropism of the chickens to feed is used for inducing the chickens to enable the chickens to naturally enter the interior of the channel bin, disturbance of catching operation to chicken flocks is greatly reduced, disturbance, stress and damage to the chicken flocks caused by a traditional catching mode are effectively avoided, meanwhile, the device can be operated at any time period, and operation is convenient. And after the chickens enter the channel bin, the blocking rods can prevent the chickens from flowing back to escape from the channel bin, the catching success rate and efficiency are remarkably improved, and a large amount of manpower and time cost are saved.
