Description
Technical Field
The invention relates to an organic planting method of cherry tomatoes rich in organic selenium.
Background
Cherry tomatoes are also called cherry tomatoes and small tomatoes, are fruit-type small tomatoes which can be eaten directly, are fresh, tender and juicy in taste, are sweet and delicious in taste, are increasingly popular with the masses and gradually become novel fruits favored by people. The cherry tomato contains nutrient components such as sugar, organic acid, mineral substances, multiple vitamins and the like, particularly contains VC necessary for human bodies, has the content 1.7 times that of common tomatoes, is an unavailable 'fruit and vegetable', is a main source of lycopene in human diet, is deeply favored by people, and is one of four fruits preferentially popularized by grain and agriculture organizations of the United nations because of the effects of delaying senility, enhancing resistance, promoting development, resisting cancer, preventing cancer and the like. In recent years, with the development of leisure agriculture, the popularity of sightseeing and picking, the market demand of cherry tomatoes is increased day by day, and the planting area is larger and larger. In view of the characteristics of cherry tomatoes that are suitable for fresh eating or ready-to-eat after picking, two major factors of safety and good mouthfeel become especially important. Among the safety standards of a plurality of agricultural products, the organic standard is strict, and the organic standard gives consideration to environmental protection and food safety at the same time, so that consumers are relatively approved and relieved. In addition, selenium is one of essential nutrient elements for human body, and various diseases of the body are related to selenium deficiency (such as keshan disease, Kaschin-Beck disease, cancer, anemia and the like), but excessive selenium intake has toxic effect on the human body. Research shows that selenium in food less than 0.05 mg/kg causes selenium deficiency of human body; poisoning phenomena can be generated when the concentration is more than 3-5 mg/kg; the safe range is between 0.1 and 0.36 mg/kg. The food is the main source of selenium for human bodies, the selenium content of the food produced on the selenium-rich soil is high, and the selenium content of the food produced on the low-selenium soil is often low, so that the requirement of the human bodies cannot be met. Therefore, the production of cherry tomatoes rich in organic selenium has a great space in the future health market.
