Fertilization should not be excessive: due to the high temperature and high humidity in the greenhouse, organic fertilizers decompose quickly, and the amount of nitrogen fertilizers is volatile. Therefore, over-fertilization can easily cause fertilizer damage. For greenhouses that have been continuously growing vegetables for more than three years, the amount of chicken manure and cow dung should be controlled within 2,500 kilograms per mu, and the amount of chemical fertilizer applied should be reduced by about 50%, and boron, zinc, and magnesium should be supplemented. Fine fertilizer.
The temperature of the greenhouse should not be too high: Some vegetable farmers mistakenly believe that the temperature is high and the vegetables grow faster. In fact, the maximum temperature requirement for most vegetables is generally 32°C. If the temperature is too high, the growth of young fruit will be inhibited, and the vegetative growth and reproductive growth of plants will also lose their balance, and the output will not only rise but will also decrease. Some varieties even have the phenomenon of only long vines and not long fruit.
Keep seedlings not too dense: It was determined that 50% of photosynthetic products will be consumed by vegetative plants when 2 tomatoes are planted per square meter, and 50% of photosynthetic products are used for fruit growth. If 4 plants are planted per square meter, vegetative bodies will consume 70% to 80% of photosynthetic products. Therefore, excessive dense planting leads to reduced yield and is prone to various bacterial diseases.
We may hear of the Face Recognition, so what does this Face Recognition mean?
The Face Recognition(or the Facial Recognition) is a kind of biometric recognition technology based on the human facial feature information. The Face Recognition(AI Face Recognition) also refers to a series of related technologies that use a camera to collect images or video streams containing human faces, and automatically detect and track human faces in the images, and then recognize the detected faces.
The Face Recognition System(Face Recognition Identification) integrates various professional technologies such as the artificial intelligence, machine recognition, machine learning, model theory, expert system, video image processing, etc. It also needs to combine the theory and implementation of the intermediate value processing, and is the latest application of the biometric recognition. The realization of the core technology shows the transformation from the weak artificial intelligence to the strong artificial intelligence.
As time goes by, the Face Recogniton Technology(Face Recognition Thermometer) is becoming mature and mature and some mutifunctional Face Recognition Devices have been "born", and one of the most popular mutifunctional Face Recognition Devices is the Face Recognition with the Body Temperature Detection function(AI Face Recognition Camera). This kind of Face Recognition Devices perfectly solved many problems. For example, the touching with people who need to be detected the body temperature can be avoided; a lot of detection time, energy, procedures, and labor can be saved; the detection difficulty can be decreased. So convenient! And this kind of Face Recogniton has helped a lot since the COVID-19 occurred, and it may help more in the future.
