Flue-cured tobacco wide-narrow row high-low ridge planting method

Номер: CN104285627A
Принадлежит:

The invention provides a flue-cured tobacco wide-narrow row high-low ridge planting method. According to the method, plants are distributed alternatively in wide and narrow rows and high and low ridges and plant distance is determined, wherein the row distance of the wide rows is 110-120 cm, the row distance of the narrow rows is 75-95 cm, the height of wide row ridges is 25-30 cm, the width of the ridge surfaces of the wide row ridges is 60-80 cm, the height of narrow row ridges is 10-20 cm, and the width of the ridge surfaces of the narrow row ridges is 30-40 cm. The aim of optimizing flue-cured tobacco group structures is achieved, ventilation and light-permeable conditions of tobacco leaves on the upper portion and on the lower portion are improved, temperature and humidity conditions of soil are adjusted, and disease and pest infection of flue-cured tobacco is effectively prevented.

Preparation method and application of Mn3O4 nano material

Номер: CN116395748A
Принадлежит:

The invention discloses a preparation method and application of a Mn3O4 nano material. According to the preparation method, a biomimetic mineralization method is used for reference, organic protein is used for in-situ regulation and control of crystallization and mineralization of soluble manganese salt, the Mn3O4 nano-material with a lamellar structure is obtained, and the prepared Mn3O4 nano-material not only has catalytic functions of glucose oxidase and catalase, but also has a good photo-thermal conversion characteristic; a glucose energy source on which tumors live is hopefully consumed through catalytic action, and tumor growth is effectively inhibited by utilizing starvation therapy in cooperation with photothermal/photodynamic action.
