What is the annual output of an acre of rice in South China?

Generally 700-800 kg (natural disasters are not accepted).

Now hybrid rice is widely planted in the south.

And hybrid rice:

The first phase (1996-2000) is 700kg/mu;

Phase II (2006 54 38+0-2005)800 kg/mu.

Since 1976, hybrid rice has been widely popularized in China, with an average yield increase of about 20% compared with conventional rice. Yuan Longping and his hybrid rice shocked the world. In 2000, the first phase of super hybrid rice he presided over achieved the goal of 700 kilograms per mu. In 2004, the goal of 800 kilograms per mu in the second stage was achieved ahead of schedule.

Peiliangyou 0293, which was bred by Luo Xiaohe, a research group of super rice in Yuan Longping, has an average yield of 850 kilograms per mu for 500 mu, and can reach about 700 kilograms for large-scale planting. And C Liangyou 396 can also reach this level, which is the two-line super rice variety with the highest yield at present.
