【摘要】 为优化烟草漂浮育苗培养基质和营养液配方,进行了共计7个处理的试验。结果表明:以一定比例的碳化谷糠、泥炭、蛭石和膨化珍珠岩配成的基质有利于培育壮苗。营养液则以一定比例的硝酸铵、硫酸铵、尿素和微量元素的配方较好。更多还原

【Abstract】 Experiments including seven treatments of medium ratio and nutriculture ratio were carried out to study their effect on tobacco transplant growth and development in floating system. The results show that the media mix of peat, vermiculite, fine perlite and carbonized chatff works as well as the media mix of peat, vemiculite and fine perlite which is recommended to tobacco transplant production. Carbonized chaff which is the native source as medium materials instead of peat is feasible, and instead partially of peat was more suitable to tobacco root development. Nutriculture with small quantity urea is of benefit to tobacco seedling growth and development.更多还原
