AI Technical Summary

Technical Problem

Rice leaves in saline-alkali land are prone to dieback, leading to reduced yield and quality, and existing technologies lack effective solutions.

Method used

A compound reagent consisting of magnesium sulfate and N-acetyl-5-methoxytryptamine was sprayed on rice leaves. The ratio and concentration of the reagent were adjusted according to the soil salinity. This significantly alleviated leaf senescence and death and prolonged the period of green leaves.

Benefits of technology

It significantly increases rice yield in saline-alkali land, improves rice quality, extends the lifespan of functional leaves, and increases yield and palatability.
