| 以经验模型中的逐级订正模型为依据，利用位于河北省中南部的高邑黄瓜日光温室2008—2011年10～5月3个生产季的小气候观测资料，对日光温室光合、光温生产潜力进行估算。结果表明，日光温室生产季光合生产潜力63 803.7～130 556.2 kg·hm-2，一般年份光合生产潜力较高，当出现持续寡照天气时，光合生产潜力较低，日光温室生产存在一定风险；光温生产潜力54 691.1～59 683.9 kg·hm-2，生产潜力较高；温度订正系数平均在0.8以上，温度对光合生产潜力制约作用不明显。生产季内光合生产潜力以5月最大，2月最小，光温生产潜力以5月最大，1月最小。在光温条件较好的年份，日光温室黄瓜实际产量达到潜在产量的17.9%，温室黄瓜生产仍有较大的潜力空间。 |

| Based upon a progressively revised empirical model, the microclimate observation data was analyzed between October and May from 2008 to 2011 in the cucumber sunlight greenhouse, located in Gaoyi county, southern central Hebei Province. Potential productivity by photosynthesis and light-temperature in greenhouse had been estimated. The results showed that photosynthetic potential productivity values in the greenhouse of one crop period were 63 803.7～130 556.2 kg·hm-2, which was higher in general years and lower in overcast days. When photosynthetic potential productivity value was very low, the greenhouse production would be at risk. Light-temperature potential productivity values in the Greenhouse of one crop were 54 691.1～59 683.9 kg·hm-2. The average temperature correction coefficient was at least 0.8, meaning that the restriction of temperature on photosynthetic potential productivity was not obvious. The photosynthesis potential productivity during the whole crop period reached most in May and least in February. The light-temperature potential productivity was highest in May and lowest in January. When optimal light and temperature conditions could be satisfied, the actual yield of cucumber in greenhouse had reached 17.9% of the potential yield, suggesting that great potential in increasing cucumber yield yet remained to be fulfilled. |
