| 摘要: |
| 提出了用作地膜材料的改性海带全粉的生产工艺，将改性海带分替代褐藻酸钠用于生物材料地膜的生产，用４份改性海带全粉替代１份褐藻酸钠即可得到满意铺布要求的薄膜，成膜材料成本降低４０％，进行了改性海带分对膜性能的影响的试验，结果表明，除透光率下降外其余参数基本与使用褐藻酸钠相同。 |

|
| Abstract: |
| The production technique of Laminaria japonic powder denatured chemically is proposed. The powder mulch film can be used to replace alginate. One-share Laminaria jaPonic powder as a substitute of four-share alginate, can meet the requiremensts of the qualified film. The material cost can be reduced by 40%. The influences of denatured Laminaria jaPonic powder on property of film are investigated. All is similar to using alginate except transmisslvity. |
