vegetable testing
The inspection of vegetables was mainly to test the quality and safety of agricultural products. Common vegetable testing items included pesticide residue testing, heavy metal testing, and food ingredient testing. Pesticide residue testing mainly focused on indicators such as organic phosphorus pesticide, carbanate pesticide, and cypermethrin. Heavy metal testing mainly focused on mercury, lead, mercury, and other elements. The detection of food ingredients mainly focused on preserving agents, flavor enhancing agents, and coloring agents. The vegetable test could assess the safety of vegetables and prevent the impact of excessive pesticide residue and heavy metal pollution on human health. Commonly used vegetable testing equipment included food safety detectors, food heavy metal detectors, pesticide residue detectors, solid phase extraction detectors, and nitrogen blowing detectors. The vegetable testing could be carried out by the national quality inspection unit or a third-party testing organization. The third-party testing organization had the advantages of short testing cycle, low cost, and accurate and reliable testing data.

In addition, there were other types of instruments, such as food moisture detectors, PH meters, kjeldahl nitrogen determiners, fat determiners, spectrums, ultraviolet-visible spectrums, atomic absorption spectrums, etc., which could be used to detect moisture, ph value, protein content, fat content, etc. in vegetables. In general, the application of vegetable testing equipment could ensure the food safety of vegetables and protect the health of consumers.
Is it a vegetable?
Niluo was a word that existed in the Jianghuai dialect. It was used in Jiangsu, Zhejiang, Shanghai, Jiangxi, Fujian, and Guangdong. The meaning of the Chinese Nut was referring to a dish like the Chinese Nut. In the northern dialect, the Chinese Nymphoides referred to water shield. Therefore, it could be said that the leek was another name for the water shield.
vegetable sorter
The main responsibilities of the vegetable sorter included quickly and accurately sorting the vegetables according to the customer's order requirements to ensure that they could be shipped on time. They needed to be proficient in picking, carefully complete the daily picking task, and ensure that the variety and quantity of goods picked were accurate. The vegetable sorter also needed to ensure the hygiene of the food, make various records of the food, sort out the dishes that needed to be sorted that day, sort the dishes according to the order, and weigh the dishes. The sorted vegetables needed to be placed reasonably to avoid being crushed and damaged, and they needed to be labeled accordingly. They also needed to sort the dishes that needed to be sorted the next day and clean up the tools used so that they could continue to use them. The vegetable sorters needed to cooperate with each other to complete the target amount for the day. During work, vegetable sorters needed to wear clean and sanitary clothes because vegetables were food, and hygiene was very important. There were no search results for specific information on salary.
vegetable identification
Vegetables identification uses deep learning and machine learning technology to automatically identify the types of vegetables. It could be seen that some research and systems had been developed to realize the identification of vegetables. For example, some researchers used image data sets based on vegetable color and texture to construct a Consecutive neural network model. By adjusting the network layer parameters and using the parameters migration technique, they obtained the preliminary recognition results of vegetables. In addition, there were also systems that used TensorFlow trained Consecutive neural networks and Mobilnet networks based on transfer learning to identify fruits and vegetables with an accuracy of 97%. In addition, some websites and software provided free plant recognition functions that could identify vegetables and other types of plants by uploading pictures or taking photos. These systems use machine learning and big data to improve the accuracy of recognition, and some systems have an accuracy rate of more than 99%. In general, deep learning and machine learning technology could be used to automatically identify vegetables and improve the accuracy and efficiency of identification. However, the specific vegetable recognition system and application still needed further research and development.

vegetable sorting
The vegetable sorting work was the process of sorting, grading, sorting, and packaging the vegetables picked from the farmland according to certain rules. This work process included harvesting and picking, cleaning and removing impurities, sorting and sorting, inspection and quality control, weighing, packaging and tagging, product inspection and other steps. The vegetable sorter needed to divide the vegetables into different categories according to the requirements of the variety, size, appearance, quality, and maturity of the vegetables, and carry out quality testing to ensure that they met the product quality standards. They also needed to weigh, package, and label the product to ensure that the information was accurate. The job of sorting vegetables required attention to detail, quality control and sorting skills, as well as good health, teamwork, and communication skills.
vegetable picker
The vegetable picker was a machine used to pick vegetables. The vegetable picker could use a low-voltage direct current servo-motor. This kind of motor did not have carbon brushes and was maintenance-free, which prevented the carbon powder produced by the carbon brushes from polluting the vegetables. The low-voltage direct current servo-motor also had the advantages of short start-up time, large moment, and rapid start-up. In addition, the vegetable picker could also adopt a self-propelled track design, so that it could move in the greenhouse and carry out harvesting operations. However, other specific information about the vegetable picker, such as its function, brand, model, etc., was not provided in the search results.

Fetal paternity testing
Fetal paternity testing was a method that used genetic technology to confirm the relationship between the fetus and the father. Currently, there were two common methods of fetal paternity testing. One was conventional fetal paternity testing, and the other was non-invasive fetal paternity testing. The cost of a conventional paternity test was 4200 yuan per case. The results were usually notified within 5 working days, and the test report was issued within 7 working days. The cost of a non-invasive paternity test was 7500 yuan per case, and the results were usually out within 10 working days. Fetal paternity testing samples could be collected through the use of the fetus's mucus, fine hairs, or maternal peripheral blood. The advantages of non-invasive paternity testing were painless, no infection, and no risk. It could guarantee the safety of the pregnant woman and the fetus. The specific process of the paternity test included consultation, payment of the deposit, sample collection, payment of the balance, DNA testing, and reporting of the results.

The sample collection methods for the paternity test included the collection of an amnion sample, a vile sample, and a venous blood sample. The specific time and method would vary according to the pregnancy. Non-invasive fetal paternity testing can be done by collecting venous blood from pregnant women, which has no effect on the pregnant woman and the fetus. In general, a paternity test could be performed during pregnancy. The specific process included an appointment with an expert, on-site verification of identity, and sample collection. Then, the sample would be sent to the laboratory for testing. As for whether a fetus could be tested for paternity, there was no clear answer in the search results.
