Embodiment 1

[0022] Weigh sodium hydrosulfide monohydrate (NaHS·H 2 O) Add water to prepare 50 μmol L -1 The aqueous solution, the treatment solution is ready-to-use. Tomatoes, cucumbers, tobacco, and Arabidopsis thaliana, which had grown for 4 weeks, continued to dry after watering enough. During this process, the prepared NaHS aqueous solution was fumigated, and fumigated once every other day for 6 hours each time. After 10 days, the tenderest first leaf was taken and fixed, made into slices, and observed with a scanning electron microscope.

[0023] Such as figure 1 As shown, A is the upper and lower epidermis of tomato; B is the upper and lower epidermis of cucumber; C is the upper and lower epidermis of tobacco; D is the upper and lower epidermis of Arabidopsis. The four materials were divided into control group (natural state, without sodium hydrogen sulfide treatment) and treatment group, and continued drought after sufficient watering. During the period, the treatment group was...

Embodiment 3

[0028] Embodiment 3. Weigh sodium hydrosulfide monohydrate (NaHS·H 2 O) Add water to prepare 100 μmol L -1 The aqueous solution, the treatment solution is ready-to-use. Tomatoes, cucumbers, tobacco, and Arabidopsis thaliana, which had grown for 4 weeks, continued to dry after watering enough. During this process, the prepared NaHS aqueous solution was fumigated, and fumigated once every other day for 6 hours each time. After 10 days, the tenderest first leaf was taken and fixed, made into slices, and observed with a scanning electron microscope.

[0029] Such as Figure 4 Shown are the upper and lower epidermis of four materials: A is the upper epidermis; B is the lower epidermis; C is the upper epidermis; D is the lower epidermis. It was found that the stomatal density of the leaves of the treatment group fumigated by NaHS was significantly reduced. After statistical analysis, the results showed that the number of guard cells in the three materials except tobacco decreas...

Abstract

The invention discloses an application of sodium bisulfide as a plant stress-resisting agent. The plant stress-resisting agent is instantly prepared for use. NaHS is prepared into an aqueous solutionin concentration of 50-100umol.L-1, and then the aqueous solution is sprayed onto mature leaves of plants. The NaHS aqueous solution utilizes NaHS to slowly release H2S/HS- in water, so as to achievethe functions of restraining development of stomata guard cells and boosting compound of waxes on plant surface. The plant stress-resisting agent has the advantages of obvious effect, high water solubility, low cost, safety, non-toxicity and simple preparation. The plant stress-resisting agent according to the invention also can supplement sulfur (S) and sodium (Na) required by plants and has thefunction of leaf fertilizers.

Description

technical field [0001] The invention relates to the application of sodium hydrosulfide as a plant stress resistance agent, in particular to a new application of sodium hydrogen sulfide (NaHS) aqueous solution to enhance plant stress resistance and its application method. Background technique [0002] Environmental stress (drought, waterlogging, salt damage, low temperature, pests and diseases, etc.) is one of the main factors affecting and limiting crop production. In crop production, it has always been a research field that scientists have been striving to explore by creating a good agricultural ecological environment and cultivating excellent varieties with resistance to adverse environmental traits to improve the yield and quality of crops. [0003] The leaf is the only vegetative organ of the plant that is completely exposed to the air, and plays an important role in the communication between the plant and the environment, mainly for transpiration and photosynthesis. Th...
