摘要: 根据在自控玻璃温室内甜椒试验资料和同期的环境气象资料,运用数理统计分析方法,建立了甜椒叶龄模式、果实生长和果重模式。叶龄生长符合植物生长模型,影响叶龄生长的主要环境气象因子在打顶前是日平均气温13~22℃的有效积温,打顶后是日平均气温13~25℃的有效积温。影响甜椒果实膨大的主要环境气象因子是座果后的日平均气温16~23℃的有效积温、日照、温度日较差和CO2浓度,甜椒果实膨大与环境气象因子间的关系呈对数形式。果实生长期的长短与日平均气温14~23℃的有效积温、日照、温度日较差和CO2浓度有关。果实的重量与日平均气温14~23℃的有效积温、温度日较差和CO2浓度有关。开花前2d至开花后3d的日平均光照小于1.5×1041x,开花后3~12d日较差小于6.5℃,开花前18d至开花后3d日平均相对湿度大于82%时阴果明显增多.

Abstract: Based on the observed pimiento and meteorological data in the same period in self-controlled greenhouse, the model were simulated by mathematical statistical method for pimiento on number of leaves and growth and weight of fruit.The number of leaves for pimiento agreed with the model of plant growth. The key meteorological factors were effective cumulative day average temperature from 13℃ to 22℃ before tip cutting, 13~25℃ after tip cutting.The meteorological factors affecting the growth speed of the fruit were effective cumulative average day temperature from 16℃ to 23℃, sunlight, daily temperature range, and concentration of CO2 The growth speed of the fruit follows the logarithm rule.The length of fruit growing period and fruit weight depend on effective cumulative day average temperature from 14℃ to 23℃, sunlight, daily temperature range, and concentration of CO2.The meteorological factors for abortive fallen fruit were sunlight less than1.5×1041x 2d before flower and 3d after flower, daily temperature range less than 6.5℃ 3~12d after flower and relative humidity higher than 82% 3~18d after flower.
