Effects of soil moisture on 13C assimilate redistribution and grain yield components in wheat

In this study, optimizing micro-sprinkler water saving irrigation can improve root development, promote photosynthetic product transport, and increase average grain filling rate and grain filling time, thereby increasing grain yield.This study provides valuable insights into improving sustainable wheat production in micro-water-saving irrigation agricultural cropping systems, and it may provide a practical framework for striking a balance between groundwater protection and food security.
