This invention provides the application of polyferric sulfate in improving plant salt stress resistance and / or improving saline-alkali land, belonging to the field of agricultural technology. The polyferric sulfate application provided by this invention can effectively improve the germination ability of plant seeds under salt stress, effectively enhance the activity of plant antioxidant systems and photosynthetic efficiency, thereby effectively improving the survival rate and growth performance of plants under salt stress. Simultaneously, polyferric sulfate can effectively reduce the EC value of saline-alkali soil, thereby effectively improving the germination rate of plant seeds in saline-alkali land and effectively improving saline-alkali land. This invention is simple to operate, low in cost, and environmentally friendly, suitable for enhancing the salt and alkali tolerance of plants, and has broad application prospects.

This invention relates to a whole coconut husk mixed cultivation substrate and its preparation method, belonging to the field of soilless cultivation substrate technology. The beneficial effects of this invention are as follows: This invention directly crushes whole coconut husks without separating the coconut husk fibers, producing a whole coconut husk mixed cultivation substrate with a short fiber content as high as 40%~60% in one step. This overcomes the long-standing technical biases that "coconut husk fibers are difficult to crush directly" and "coconut coir should have its fibers removed as much as possible." The short fibers in the product form a three-dimensional network structure, significantly improving the substrate's aeration and root development environment, increasing crop root density by more than 50%. Simultaneously, it eliminates the fiber separation and re-mixing processes, reducing equipment investment by approximately 30% and energy consumption by approximately 40%. It utilizes ambient temperature mechanical cold pressing for desalination and dehydration, without thermochemical damage, resulting in a product with an EC value as low as 0.5~1.5 mS / cm and a resilience rate ≥99%, combining excellent cultivation performance, simplified process, and convenient storage and transportation.

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.
