GhSZF3 The gene can improve plant salt tolerance, and can significantly improve the seed germination ability of transgenic Arabidopsis under salt stress, which has important significance for cultivating new transgenic plant varieties with salt stress resistance. The gene can provide a wider gene source for directional editing, improvement of cotton salt resistance and molecular breeding of various plants and crops.

This invention relates to the field of agricultural technology, and particularly to the application of zinc citrate in improving plant salt stress resistance and remediating saline-alkali land. This invention is the first to utilize zinc citrate to enhance plant salt stress resistance. Zinc citrate can effectively improve the germination ability of plant seeds under salt stress, increase the activity of the plant's antioxidant system and photosynthetic efficiency, thereby effectively improving the survival rate and growth performance of plants under salt stress. Simultaneously, zinc citrate can effectively reduce the EC value of saline-alkali soil, achieving effective remediation of saline-alkali land, and further improving the germination rate of plant seeds in saline-alkali land.
