Embodiment 1

[0045] Embodiment 1: Enhance the ability of rice to resist salt stress

[0046] The seeds of rice "Wuyujing 3" were used as materials, and the rice seeds were subjected to salt stress treatment with 150mmol / L NaCl solution for 1 day, and the enrichment with different saturations was prepared by adding hydrogen released from the steel cylinder into distilled water. Hydrogen liquid plant growth regulator, to study the effects of hydrogen-rich liquid plant growth regulators with different saturations on rice seed germination under salt stress. The hydrogen saturation of the hydrogen-rich liquid plant growth regulator is 0.1%, 1.0%, and 10.0%, respectively, and the H2-free 2 It was found that hydrogen-rich liquid plant growth regulators with different saturation levels can alleviate the inhibition of rice seed germination under salt stress, as shown in Table 1, of which 1.0% saturation (releasing about 0.02ppm hydrogen) The relieving effect of hydrogen-rich liquid plant growth re...

Embodiment 2

[0052] Embodiment 2: Improve rice seed amylase activity, reducing sugar and soluble total sugar content under salt stress

[0053] The seeds of rice "Wuyujing 3" were used as materials, and the rice seeds were subjected to salt stress treatment with 150mmol / L NaCl solution for 1 day, and then hydrogen obtained by electrolysis of water was added and distilled water was added to prepare rich Hydrogen liquid plant growth regulator, to study the effects of hydrogen-rich liquid plant growth regulators with different saturations on amylase activity, reducing sugar and total soluble sugar content during rice seed germination under salt stress. The saturation degrees of hydrogen-rich liquid plant growth regulators are 0.1%, 1.0%, and 10.0%, respectively, and the H2-free 2 The solution was used as a control test, and the study found that hydrogen-rich liquid plant growth regulators with different saturations could increase the amylase activity, reducing sugar and total soluble sugar co...

Embodiment 3

[0056] Embodiment 3: Enhance the ability of wheat to resist osmotic stress

[0057] Using wheat "Yangmai 13" seedlings at the two-leaf one-heart stage as materials, the wheat seedlings were subjected to osmotic stress treatment with 20% (w / v) polyethylene glycol (PEG) solution for 1 day, and added by KBH 4 Hydrogen gas was obtained and fed into different saturation hydrogen-rich liquid plant growth regulators prepared in MS culture medium to study the effects of different saturation hydrogen-rich liquid plant growth regulators on the growth of wheat seedlings under osmotic stress. The saturation degrees of hydrogen-rich liquid plant growth regulators are 0.1%, 1.0%, and 10.0%, respectively, and the H2-free 2 The solution was used as a control test, and the study found that hydrogen-rich liquid plant growth regulators with different saturations had alleviating effects on the growth inhibition of wheat seedlings under osmotic stress, as shown in Table 3, wherein 1.0% saturation ...

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...
