摘  要:
采用侯光良等介绍的作物生产潜力公式对贵州主要作物生产潜力进行估算。结果表明:①贵州主要作物气候生产潜力变幅为3486 5~19653 7kg/hm2,平均值玉米为11247 5kg/hm2,水稻为16264 3kg/hm2,油菜为4744 6kg/hm2,小麦为7167 9kg/hm2;②贵州不同地区作物气候生产潜力以东部、北部、东南部较高,中部和东北部居中,西北部较低;③与实际产量相比,贵州作物近期潜力开发程度为5 0%~23 0%,中期潜力开发程度为29 6%~55 9%,作物增产潜力仍相当大;④贵州必须在提高作物单产和品质上加大力度,粮食安全才有保障。

摘  要:
The main crop potential productivity of Guizhou was calculated by means of the formula,which was introduced by Ho Guang-liang and etc.The results showed:(i) the main crop potential productivity of Guizhou ranged from 3486.5 kg/ha to 19 653.7kg/ha for rice, the average yield of different crop was 11 247.5 kg/ha for maize,16 264.3kg/ha for rice,4744.6kg/ha for rapeseeds and 7161.9 kg/ha for wheat,respectively ;(ii) the main crop potential productivity in the east, north and south-east of Guizhou was higher, that in the middle and south-east of Guizhou was mean and that in north-west of Guizhou was lower; (iii) compared with the actual yield, crop potential increasing rate of Guizhou was 5.0 %-23.0 % in recent period and 29.6 %-55.9 % after a rather long time;(Ⅳ)food security of Guizhou could be guaranteed only by enforcing practices of increasing yield and quality of crop.
