根吃掉了。如果要用力才能拔起来，那可能是肥烧的或狗狗干的。
The way to distinguish between grub or larvae damage and fertilizer or dog
damage is to examine the edge of the dead patch. If the grass is growing
the same on the edge as it is on the rest of the lawn, grubs are the problem
. If the grass around the brown spot is growing luxuriantly and taller,
greener, and more lush than the test of the lawn -- the dead spot is likely
caused by fertilizer or dogs. With grub damage, you'll be able to pull the
dad grass from the ground. With fertilizer or animal burn, the grass will
still be attached to the roots and will not easily pull from the ground.
