    The present outline of the relief of the central part of Kwangtung province was formed toward the end of the Mesozoic orogenic movement. Larga hodies of granitic intrusion were produced in the east and west sides of the Peikiang and in the south side of the lower Sikiang. As a result of these granitic iniru-sions, high lands were formed. The area between the high lands was occupied by a low basin.

    The so-called "agricultural characteristic temperature" denotes the daily mean temperature of 0°, 5°, 10° or 15°C and accumulated temperatures of 10°C up. Every different mean temperature is chaaacteristic of a certain rural phenomenon, e,g., daily mean temperature above 0°C charactsrizes the farming season; above 5°C, the period of growth; above 10°C, the time of buoyant growth; and above 15°C, the period for planting cotton and rice. The accumulated temperatures of 10°C up are to a certain degree correlated with the distribution of crops.
