| 摘 要： | 以风化石为主要原料,蔗渣、药渣为辅料,组合成4个基质配方,以常规草炭基质为对照进行育苗对比试验,研究不同风化石含量配以一定量的有机质辅料对烟苗出苗率、成苗率以及不同阶段烟苗素质的影响.结果表明,40％～70％风化石加一定蔗渣、药渣所育烟苗均能达到壮苗标准.其中40％风化石含量的基质处理出苗率和成苗率比对照分别提高4.02个百分点和1.48个百分点；50％风化石含量的基质处理茎叶及根系干物质累积75 d时分别比对照增加0.13和0.05g.其他几个基质配方所育烟苗的千物质累积、地上部分-地下部分协调性及成苗素质等指标都与对照接近,甚至优于对照；育苗成本较对照降低47.8％～56.2％,说明以风化石为主要原料来代替草炭作烤烟漂浮育苗基质完全可行.

| Abstract: | Using the wind fossil as the main materials,dregs and bagasse as the supplement materials,we combined into 4 substrate formulation to do parallel experiment with the peat substrate for formula breeding.The influence of different wind fossil content with a certain amount of organic materials on sprouting rate,maturing seedling rate and seedling diathesis of different seedling stage was studied.The results showed that the formulation with 40 % to70 % wind fossil plus a certain dregs and bagasse could also mee... |
