以稻壳为原材料，采用大豆蛋白基黏合剂捏合成型制备育苗钵，研究了稻壳育苗钵的耐水特性；通过育苗试验研究了育苗钵对黄瓜的生物学效应，并分析了育苗钵育苗周期与拉伸强度间的相关性。结果表明：育苗钵最大平衡吸水率及厚度膨胀率分别为26.78%和10.73%，具有较好的耐水特性；育苗钵经干湿热循环处理后拉伸强度最大降幅约50%（P<0.05）。生物学效应试验表明，育苗钵高浓度浸提液对黄瓜发芽率影响显著，低浓度浸提液对种子发芽率有一定的促进效应；育苗效果试验验证育苗钵对黄瓜生长长势有促进作用。以干湿热循环处理后拉伸强度为自变量，育苗钵育苗周期为因变量，建立了相关模型y=-0.35X2+9.43X-5.85（R2=0.9473）。该育苗钵具有适宜的耐水性和强度，育苗效果良好，是一种理想的育苗器具，可应用于作物的育苗。

In recent decades, it has drawn increasing interest to develop environmentally friendly products with natural plant fibers as filler. Straw nursery containers, made from crop straw, enable seedlings to be transplanted directly into soil without harming roots. They are alter-natives to plastic pots and have been widely used in agri-forestry production. In the present study, a new type of bio-containers with rice husk as filler and soybean protein as adhesive through thermal compression process was developed. The water resistant property of the con-tainers was assessed and the effect of these containers on seed germination and growth of cucumber was also evaluated. The correlation be-tween tensile strength and seedling period was further studied. Results showed that the maximum balance water absorption rate and thick-ness expansion rate of the nursery containers were 26.78%and 10.73%, respectively, indicating that the containers had a good resistance to water. The greatest reduction of their tensile strength was about 50%(P<0.05)after four dry-wet and heat cycle s. The germination of cu-cumber seeds was promoted by H2O-extracting solution of the containers at low concentrations, but inhibited at high concentrations, which might be due to the formaldehyde from urea formaldehyde resin. Compared with plastic containers, the new type bio-containers could signif-icantly promote the growth of cucumber seedlings at seedling raising period. The tensile strength and seedling period had a significant corre-lation as y=-0.35X2+9.43X-5.85(R2=0.947 3). These results suggest that straw bio-containers would be a good nursery containers for both agriculture and environment.
