Some mistaken understanding of seed germination box
The seed germination box is an incubator used for cultivating seeds and can artificially set parameters such as temperature, humidity, and illuminance needed for seed germination. Therefore, it is the laboratory's preferred instrument. In the process of plant growth, a suitable environment can allow the plant to grow healthily and quickly. Factors in the environment influence each other and promote each other. In the environment, these factors are all variability, and it is difficult to regulate and control. It is extremely inconvenient to regulate in time. It has brought great invariability to some studies. It is precisely because of this that institutions have increased their research efforts, and precision seed germination boxes have come out one after another. These instruments have solved the uncontrollability of various factors in the environment and are convenient for everyone to carry out. Test and seed germination. Baby neck ring is a swimming practice ring specially designed for babies. During the period when the baby can't raise his head, use the swimming ring worn on the baby's neck. The height of the baby swimming pool is basically designed according to the height of the baby on the neck. The baby swimming ring is divided into different specifications such as S/M/L/XL. It is made of rubber, PVC and other materials, and has different shapes such as round, star, and animal.

However, when using the seed germination box for testing is not a panacea, people often have many mistakes in the use of the above points, mainly in the following aspects: Although you can arbitrarily set the running time of each test section , temperature, humidity, light value. However, the temperature difference between the layers in the box is still there, and the temperature difference at different levels and in different regions still exists. There are also differences in the temperature inside and outside the same floor, and the temperature difference between the outside of the upper and lower sides of the incubator above the larger one is even greater. Therefore, it is desirable to pay special attention to this problem when using it. Therefore, after using the thermometer to measure in the process of use, it is found that the temperature of the uppermost layer of the precision seed germination box is not the highest, the middle temperature of the box is the highest; the actual temperature in the intelligent artificial climate incubator and the box There is still a certain difference in temperature. In general, the temperature in the body is higher than the temperature set outside the box. The main reason is that the plant's breathing and photosynthesis are used. When using an intelligent artificial climate incubator, the number of seeds used for germination is corresponding. It's not necessarily the bigger the better to measure.
PVC is a new type of material. Compared with plastic, PVC Material has certain advantages, such as good gloss, good hand feeling, good comfort, firmness, and not easy to leak water. In addition, the double airbags basically used in baby swimming rings made of PVC material. , The design of four airbags basically does not have potential safety hazards.
