Most of Sichuan received scant or no rainfall in February, and there is no rain forecast before the end of March.
Abnormally warm temperatures have added to the problem that has hit Chinese farmers there, and there have been reported losses of nearly 300 million yuan ($38m, £19m), according to the official Xinhua news agency.
It is not just Sichuan that is experiencing extreme problems because other parts of China have had abnormal weather conditions recently as well, for example, in the Chinese northwest hundreds of thousands of people needed emergency supplies earlier this year due to very low rainfall in Shaanxi province.
