长江流域应用番茄快速育苗的方法以后,已从过去冷床育苗120～150天的苗龄,缩短到70天左右,主要是着眼于温度因子的研究与运用,即利用催芽室、塑料大棚、塑料小棚、加温线等新型设备,满足其温度条件,以加速育苗进程。这是因为冬春温度过低,温度成为当前快速育苗的限制因素之故。但是,当温度因素达到一定要求后,而对肥、水、气、光等其 After applying the method of rapid tomato seedling growth in the Yangtze River Basin, the seedling age of 120-150 days in cold bed nursery has been shortened to about 70 days, mainly focusing on the research and application of temperature factors, namely, germination room, plastic greenhouse, plastic Shed, heating lines and other new equipment to meet the temperature conditions in order to speed up the nursery process. This is because winter and spring temperature is too low, the temperature has become the limiting factor of the current rapid nursery. However, when the temperature reaches certain requirements, while the fertilizer, water, gas, light and so on
