根据上海东海蔬菜示范基地1996～1997年2茬甜椒产量资料及同期温室内的气象资料,运用数理统计方法分析气象条件对甜椒产量的影响,初步得出温室中甜椒生长关键期的适宜气象指标为播种约30d日最低温度为14.5～15.0℃,日最高温度25.0～25.5℃,CO_2浓度400～450mg/kg;播种后加热管温度50℃;而播种后10d左右相对湿度维持在75％,80d左右光照强度为6～6.5万1x。
According to the yield data of the second crop of peppers from 1996 to 1997 in Shanghai East China Sea Vegetable Demonstration Base and the meteorological data in the greenhouse during the same period, mathematical statistic method was used to analyze the influence of the meteorological conditions on the yield of sweet peppers. The meteorological indicators were: the lowest temperature of about 30 days after sowing was 14.5-15.0 ℃, the highest daily temperature was 25.0-25.5 ℃ and the concentration of CO 2 was 400-450 mg / kg; the temperature of the heating pipe after sowing was 50 ℃; while the relative humidity was maintained at 75% , About 80d light intensity of 6 ~ 65000 1x.
