Abstract

The invention discloses application of selenium in preparation of a preparation used for improving the drought resistance of tobaccos, belonging to the technical field of agriculture. According to theinvention, the selenium is in a high valence state. With the prepared preparation, the growth condition of tobaccos in a drought can be improved, and the drought resistance of the tobaccos is enhanced; so the yield and internal quality of the tobaccos are improved, and effective reference is provided for safe production of tobaccos and other grain crops.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to the application of selenium in the preparation of a preparation for improving the drought resistance of tobacco. Background technique [0002] Drought is one of the important stresses that affect the process of plant growth and distribution. Among the biotic and abiotic stresses, the loss of crops is second only to the stress of diseases and insect pests. As an important model plant and economic crop in my country, tobacco’s growth and development require high environmental soil water content. If the field water capacity during the growth and development period is below 50%, the quality and yield will be greatly affected. [0003] Selenium is an essential element for the growth and development of animals and a beneficial element for plant growth and development. Studies have shown that applying selenium in an appropriate concentration range can enhance the ability...
