First, is it harmful or harmful to the vegetables in the greenhouse? In our Earth, the climate in the northern and southern hemispheres is exactly the opposite, but many plants, such as apples, can be grown in both the northern and southern hemispheres. The apples in the southern hemisphere are transplanted into the northern hemisphere. The season is reversed, but it can still adapt to the environment of the northern hemisphere as long as you It can provide plants with an environment suitable for its growth, it can grow healthily, and its texture is excellent. High temperature and humidity in greenhouses are not conducive to the degradation of pesticides. Therefore, vegetables in greenhouses are recommended to use biological pesticides instead of chemical pesticides. Just like people are sick, many people are reluctant to use drugs that have side effects, but they use traditional Chinese medicine. If there are biological pesticides rather than chemical pesticides used in greenhouses, there will be no problem of pesticide degradation (the so-called biological pesticides are those that use biological living organisms or their metabolites) to kill or inhibit agricultural pests). Therefore, the off-season vegetables produced in the greenhouse are safe. Second, whether the vegetables grown by farmers are green vegetables? 1. The environment of the place where the vegetables are grown by the farmers can not be confirmed if the irrigation water quality is up to standard; 2. People's farm manure fertilizers are often not subjected to high-temperature fermentation treatment. Unfamiliar livestock manure contains active pathogens, viruses, parasite eggs, weed seeds, etc., easily infecting pests and diseases, causing soil water pollution, and easy pathogenic microorganisms. Intrusion, causing the occurrence of infectious diseases, causing greater losses; 3. Whether or not vegetables use pesticides, and whether the pesticide application method is correct cannot be confirmed. Third, small tomatoes, bell peppers, UFO melon, banana squash and other beautiful vegetables are genetically modified? A list of genetically modified foods is circulated on the Internet, including "Cherry Fruit, Big Color Pepper, Small Pumpkin, Gherkin". In fact, these are not genetically modified. Plants are a valuable asset endowed by nature to human beings. Humans have cultivated and domesticated wild plants in long-term farming practices, thus forming a rich variety of crops. The characteristics of the plants themselves, the types of wild plants, the earth's climate and ecological conditions, and artificial selection have resulted in the diversity of crops. Wang Zhixing, a researcher at the Institute of Biology, Chinese Academy of Agricultural Sciences, said that small tomatoes, also known as cherry tomatoes and cherry tomatoes, are tomato varieties that have existed since ancient times. They were only small in size, inconvenient for picking, and low in yield. They were used only as ornamentals and were later found to be convenient for consumption. After the taste has been improved, it becomes popular. Small size is a natural genetic difference, not the result of genetic modification. Wu Gang, an associate researcher at the Institute of Petroleum Research of the Chinese Academy of Agricultural Sciences, said that the cherry tomatoes are closer to the wild state before artificial domestication. In fact, wild chestnuts, walnuts, and apples are also much smaller than conventional cultivars. These miniaturized species are all derived from germplasm resources with ancestral primitive genes and have nothing to do with transgenes. Tomatoes, for example, are native to Peru, Ecuador, and Pauli in South America. Almost all wild species can still be found there. Local aborigines have been picking food from nature since ancient times. With the spread of tomatoes to Mexico in southern North America, the natural evolution and artificial selection have produced rich and varied variations in the fertile, warm and humid climate of the Gulf of Mexico. The varieties of tomatoes currently on the market are very rich and varied. The color pepper is found in rich colors because it contains different types of anthocyanins. Its color is only due to the genetic genetic differences that exist in nature. It is related to varieties and has nothing to do with genetic transformation. Only in the past has not been planted in large areas, ordinary consumers rarely see it.
