烤烟漂浮育苗是将幼苗根系生长载体分为固体基质 (腐殖质 +膨胀岩石 )与液体水营养液两部分 ,通过塑料泡沫板承填基质漂浮在水面上的一种新的育苗方法。它改变了传统育苗土壤介质条件 ,使根系生长环境的水、气、热状况不同于传统育苗土壤。因此 ,研究漂浮法育苗温度与烟苗生长? Flue-cured tobacco floating seedling is a new seedling raising method that the seedling root growth carrier is divided into solid matrix (humus + expansive rock) and liquid water nutrient solution and floats on the water surface through plastic foam board. It has changed the traditional media of seedling soil conditions, so that the root growth environment of water, gas and heat conditions are different from the traditional nursery soil. Therefore, research floatation seedling temperature and tobacco seedling growth?
