Peach, apricot and pear have been planted for five years, and the jujube tree will pay back the money that year (indicating that the jujube tree bears fruit early). Is the jujube tree dead in that year, and is the willow tree alive in that year (if the jujube tree doesn't sprout in the year after planting, it doesn't necessarily mean dead). Jujube and wheat should be intercropped well, and the next crop should be harvested. Jujube trees should not rest in autumn and winter (indicating that jujube and wheat are suitable for intercropping).
