摘要
在夏季玻璃温室内,进行了环境因子对番茄苗期生长与生理特性影响的试验,分析了环境因子(土壤含水量、太阳辐射、空气温度、空气相对湿度等)的变化对番茄苗期的影响。试验表明:温室内太阳辐射、空气温度以及相对湿度的变化对番茄苗期的茎流量有着显著的影响,14:00时左右,茎流量达到最大;灌溉下限为田间持水量的80%时,番茄苗期长势最好。
The trial of environment shifting effects to tomato seedlings＇ growth and physiological index is put in the greenhouse at the end of summer.This trial analyzed the environment effects （soil moisture,light radiation,temperature,relative humidity of air and so on） to the plant of tomato seedlings.This trial indicates that the different light radiation,temperature and relative humidity of air has a great effect to the state of flux of tomato seedling＇s plant and at 14：00 the state of flux became to the biggest number.The plant of tomato seedling has best grow vigor when the irrigation＇s lower limit gets the 80% of water holding capacity in the farm.
