自控温室气象条件对甜椒产量的影响

Effect of meteorological conditions in self-controlled greenhouse on sweet pepper yield

摘要: 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℃，CO₂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lx。

Abstract: Based on the sweet pepper yield data in from 1996 to 1997 and meteorological data in the same period,mathematical statistical method was used to analyse the influence of the latter on the former.Favorable meteorological indexes were put forward.They were 14.5～15.0℃ of day minimum temperature of about a month after seeding,25.0～ 25.5℃ of day maximum temperature,400～450 mg/kg of CO₂ density,50℃ of heating pipe temperature after seeding,60000～65000 lx of illumination of about 80 days after seeding,75% of relative humidity of about 10 days after seeding.
