摘要
广东水稻的增产潜力，在现有育成品种条件下，通过栽培技术（包括改善生产条件），可以获得产量１１２６０５ｋｇ／ｈｍ２（每亩７５０７ｋｇ），双季稻年产２２５２１ｋｇ／ｈｍ２（每亩１５０１４ｋｇ），优质稻产量８６７７５ｋｇ／ｈｍ２（每亩５７８５ｋｇ）。提高广东粮食的自给率，在于提高单产。
The yield potential of rice in Guangdong is great with the improved varieties. It is possible to produce 11 260.5 kg/hm 2 in one season, or 22 521.0 kg/hm 2 in one year with the improved varieties, or 8 677.5 kg/hm 2 with good quality varieties and advanced cultivation techniques includung the improvement of production conditions. The increase of grain self-sufficient rate in Guangdong will depend on the yield increase of single crop, specialy the increase of rice yield in the middle and lower production areas which are nearly two-thirths of the total rice areas in Guangdong.
