| 摘 要： | 为研究水葫芦对商品基质的替代效应,采用风干水葫芦为主要替代原料,研究不同配方基质的物理、化学特性及其对黄瓜穴盘育苗生长的影响。结果表明：风干水葫芦替代50%-100%商品基质后,穴盘根坨质量好,散坨率低,幼苗株高、茎粗、单株鲜重、单株干重等指标均优于对照,但出苗率显著低于对照（P〈0.05）,幼苗叶绿素SPAD值低于对照。基质理化性质与出苗率的相关关系分析表明,风干水葫芦复配基质的通气孔隙度、总孔隙度与出苗率呈显著负相关（P〈0.05）,相关系数分别为-0.650＊、-0.687＊,电导率EC值与出苗率呈负相关,相关系数为-0.332。100%风干水葫芦处理、风干水葫芦蛭石（75：25）处理的资源利用率高,育苗质量好,是替代草炭复合基质的理想配方。采用水葫芦为原料配制的复合基质,育苗质量好,商品基质替代率可达50%-100%,为水葫芦的资源化利用开辟了新的途径。

| Abstract: | To study the substitution effect of Eichharinia crassipes for commercial substrate, with air-dried Eichharnia crassipes and fermented Eichharnia crassipes as the experimental material, physicochemical properties of media according to different combination and its influence of cucumber seedling growth were studied. The results showed that when air-dried Eichharnia crassipes replace 50%- 100% of the substrate, root system quality, stem thickness, plant height, single plant fresh were better than the control, but emergence rate and SPAD of seedling were lower （P〈0.05） than the control. Air-dried Eichharnia crassipes was better than fermented Eichharnia crassipes to make compound media. The correlation between physicochemical properties of compound media and qualities of seedlings showed that both aeration porosity and total porosity of air-dried Eichharnia crassipes had significant negative correlation with emergence rate （r=-0.650＊, r=-0.687＊）, EC had significant negative correlation with emergence rate （r=- 0.332）. The treatments of the pure air-dried Eichharnia crassipes mixed with 75% air- dried Eichharnia crassipes and 25% roseite had high resource availability and strong seedlings. Eichharnia crassipes could be used as nursery substrate without composting, that provided favorable conditions for the utilization of Eichharnia crassipes. |
