Crop sod culture management method and selenium-rich grape field management technology

Abstract

The invention relates to a selenium-rich grape field management technology, and belongs to the technical field of crop management. The selenium-rich grape field management technology is characterized in that a sod culture method is adopted for management in the planting of selenium-rich grapes to finally obtain a field management technology for selenium-rich grapes which is less polluted and high in selenium content by being combined with fertilization management, supplement of microelements and spraying. Due to the implementation of a selenium richening technology, the growth is promoted, the leaf function is enhanced, cold resistance, drought resistance, disease and pest resistance and other resistance are improved, the fruit volume is promoted to be expanded, the content of sugar of the fruit is increased and the sweet and sour rate is improved; furthermore, the storing resistance and the transportation resistance are improved; the organic selenium content in the fruit is increased obviously (10 to 50 mcg / kg) in comparison with local ordinary grapes and the mouth feel is excellent; and the residual pesticides and the environmental pollution are reduced.

[0001] The invention relates to a field management method of selenium-enriched grapes, in particular to a field management method of selenium-enriched grapes using a grass growing management method, and belongs to the technical field of crop management. Background technique

[0002] Biological enzymes are indispensable active substances in life activities, and selenium is one of the substances in the active center of biological enzymes. If the human body is deficient in selenium, the biological activity of this enzyme will be very low. Therefore, selenium is an essential antioxidant component in the human body. If selenium is deficient, people's immunity will be greatly reduced, and there is a view that the virus will consume a large amount of selenium during the replication process, which will cause selenium deficiency in the human body. In addition, it has been found that selenium deficiency is common in susceptible populations.
