Embodiment 1

[0025] 1. Prepare the solution:

[0026] MoCl 5 and Cys were prepared as a solution with a concentration of 1 mM and sonicated.

[0027] 2. Self-synthesis of Mo-S crystals:

[0028] Using a watering can, the MoCl 5 Spray evenly on the upper and lower surfaces of the leaves of Radermacherasinica (Phase bean tree). After the solution evaporates to dryness, spray the Cys solution evenly on the upper and lower surfaces of the leaves, subject to the fact that the leaves are completely soaked. Continuous spraying treatment 7d. The synthesis of its Mo-S crystal is as follows figure 1 shown.

[0029] 3. Salt resistance of plants:

[0030] (1) Use 30mM and 200mM NaCl to irrigate the roots of the bean tree containing Mo-S crystals and the control group respectively, and pour 40mL in each pot continuously for 7 days. The results are as follows: figure 2 shown.

[0031] (2) Through tests, it was found that Mo-S crystals can increase Ca under salt stress conditions 2+ The strengt...

Embodiment 2

[0033] 1. Prepare the solution:

[0034] MoCl 5 and Cys were prepared as a solution with a concentration of 1 mM and sonicated.

[0035] 2. Self-synthesis of Mo-S crystals:

[0036] Using a watering can, the MoCl 5 Spray evenly on the upper and lower surfaces of the leaves of Arabidopsis thaliana (Arabidopsis thaliana). After the solution evaporates to dryness, spray the Cys solution evenly on the upper and lower surfaces of the leaves, subject to the fact that the leaves are completely soaked. Continuous spraying treatment 7d. The synthesis of its Mo-S crystal is as follows image 3 shown.

[0037] 3. Salt resistance of plants:

[0038] (1) Use 200mM NaCl to irrigate the roots of Arabidopsis thaliana containing Mo-S crystals and the control group, and pour 4mL per pot continuously for 7 days. The results are as follows: Figure 4 shown.

Abstract

The invention discloses a method for increasing the salt-resistance performance of plants by self-synthesizing crystals, which uses the self-synthesis crystals of plant leaves to increase the salt-resistance performance of plants, and uses MoCl 5 and Cys solution using plant leaves to synthesize Mo‑S crystals in situ. Its main steps are as follows: A, MoCl 5 Spray the solution evenly on the upper and lower surfaces of the plant leaves; B. Wait for 10 minutes until the solution on the leaves evaporates, and spray the prepared Cys solution evenly on the upper and lower surfaces of the plant leaves; C. Spray MoCl regularly every day 5 And Cys solution for 7d.

Description

technical field [0001] The invention relates to the technical field of plant salt resistance, in particular to a method for improving the salt resistance performance of plants by using plant leaves to self-synthesize Mo-S crystals. Background technique [0002] Land salinization is an important global ecological problem formed under the dual effects of natural environment and human activities. It will cause osmotic imbalance, ion stress, oxidative damage and other hazards to plants, resulting in slow plant growth, reduced biomass, and even extinction. Produce. The vast area of ​​saline soil in China severely restricts land development and agricultural development. Improving the salt resistance of plants is of great significance for improving land utilization and agricultural development. Existing methods such as application of plant anti-salt agents, microbial preparations, and genetic engineering are restricted by problems such as unsatisfactory anti-salt effects and high...
