过去曾报导:在植物生长适温范围内,根系生长速度随温度升高而增快,但实践证明高温下培育的幼苗定植后缓苗慢、生长势弱。本试验以对环境条件较敏感的甜椒为试材,观察了苗期根际温度对根系生育的影响,为培育壮苗提供依据和参数。试验于早春育苗季节中,在温室及生长 In the past, it has been reported that in the range of plant growth temperature, the growth rate of root system increases with temperature, but it has been proved that the seedlings grown under high temperature have a slow growth and weak growth after planting. In this experiment, the pepper which is sensitive to environmental conditions was taken as test material to observe the effect of rhizosphere temperature on root growth at seedling stage, which provided the basis and parameters for cultivating strong seedlings. Experiment in early spring nursery season, in greenhouse and growth
