摘　　要：水葫芦的低成本、资源化、生态合理利用是水葫芦防治的发展趋势,可降解温室栽培苗钵的制作使用可简化移苗过程。基于以上考虑,对水葫芦制作温室栽培专用有机苗钵的可行性、对水葫芦制作育苗钵的方法,所需有机生态胶粘剂的制作和性能特点,苗钵对樱桃番茄的栽培效果影响进行了研究。结果发现,对水葫芦进行干燥切割后,辅以胶粘剂能制作所要求的育苗钵;采用以淀粉为基体制作的有机胶粘剂粘结并压制成形的苗钵在耐湿性方面有待于进一步提高;在栽培过程中以水葫芦为原材料制作的育苗钵对樱桃番茄苗生长的影响作用并不明显。The use of dried water hyacinth as a seed germination medium in the pot was investigated in this study. The experiments are taken to explore the feasibility of making seedling medium from incised desiccated water hyacinth, and several organic viscoloid based on starchy are practiced and of which the kind E （add a portion of hydrogen bioxide, sodium bicarbonate and sodium hydroxide to starchy） has a comparatively good viscidity, while the disadvantage is that rigidity of the medium would decrease when it encountered the irrigated water. The effect of seed germination medium prepared from dried water-hyacinth on cherry-type tomato were assessed. The result showed that the seed germination medium disassembled in about 10 days and decomposition is quite obvious in 30 days after it was transplanted into the field. And the tomato growth and yield had no significant increase.
