Grains get blamed for how much they accumulate. If the grains accumulate too much then they make more work for the farmers. If they accumulate too little, then they're starving the people. Ugh, grains just can't win with you people. They're blamed for everything.
Now the grains have accumulated a ton, they're overflowing in their grain sacks, and the farmer freezes and says, "Now those are some sexy (せき) grains."
