Abstract

The invention belongs to the fields of development and utilization of plant growth regulating substances, and discloses a hydrogen-rich liquid plant growth regulator. The saturation of hydrogen in a solvent is 0.1 to 100 percent, and the solvent is water, a 25 to 100 percent Hoagland nutrient solution, a Kimura B nutrient solution, a TAP nutrient solution or an MS culture solution. Calcium salt, salicylic acid, salicylate, salicylic acid derivative, humid acid or humic acid salt at the final concentration of 0-1,000mu mol / L is added into the solvent. Plants, plant tissues and seeds are irrigated, sprayed or soaked, the plant growth and morphogenesis can be effectively promoted, seed germination is quickened, heavy metal accumulation is reduced, and the oxidation resistance and stress resistance / tolerance are improved. The method has the characteristics of no pollution, environmental protection, low cost, and wide application range, and is applied to the fields such as farmland chemical regulation, provenance agriculture, environment and plant nutrition, plant tissue culture and cut flower preservation time prolonging.

Description

technical field

[0001] The invention relates to the field of development and utilization of plant growth regulating substances, in particular to a hydrogen-rich liquid plant growth regulator and its preparation method and application. Background technique

[0002] During the growth of crops, various unfavorable environments often appear, such as cold stress, drought stress, heavy metal stress, diseases, etc. These environments will seriously affect the growth status of crops, such as the reduction of fresh weight and dry weight, and the reduction of chlorophyll content, resulting in Decrease in crop yield and quality. In addition, the above-mentioned adversity factors will also lead to excessive production of reactive oxygen species in plants, thereby causing oxidative stress. Reactive oxygen species cause severe plant cell damage, including membrane lipid and protein oxidation, RNA degradation, ion leakage, DNA degradation, and cell death. These microscopic, molecular-lev...
