Description

可降解保水纸地膜
技术领域
    本实用新型涉及一种农业保水地膜,具体的说是一种可降解保水纸地膜。
背景技术
地膜即地面覆盖薄膜,用于地面覆盖,以提高土壤温度,保持土壤水分,维持土壤结构,防止害虫侵袭作物和某些微生物引起的病害等,促进植物生长的功能。传统的普通塑料地膜以聚乙烯或聚氯乙烯为主,其稳定性极高,降解时间长达200-300年。随着这种不可降解地膜的大量一次性使用,造成大量残膜残留在地表和土壤中,难以降解,对土壤造成了污染和损害,危害生态环境。因此开发可降解地膜成为解决地膜种植对环境危害的一条重要途径。
实用新型内容
    本实用新型目的在于提供一种可降解保水纸地膜,以解决现有塑料地膜存在的难以降解的问题。
  为了达到上述目的,本实用新型的技术方案为,一种保水纸地膜,它由三层组成,在纸质基层上复合有保温涂层和保水涂层。
本实用型新具有以下优点:
1)本实用新型所用材料都为环保、可生物降解材料,制成地膜,可解决现有保水剂不易生物降解问题。且含有的淀粉基、纤维素成分生物降解后对土壤起到营养作用。
2)本实用新型采用纸质作为主要骨架,易降解且具有良好的透气性。在两层骨架之间添加了保温涂层及保水涂层,增强了地膜保温及保水性能。
4)本实用新型可应用于蔬菜、花卉、农作物等育苗。
附图说明
图1为本实用新型结构示意图。
具体实施方式
下面结合附图对本实用新型再做进一步说明:
如图1所示,一种保水纸地膜,由三层组成,在纸质基层1上复合有保温涂层2和保水涂层3。 
纸质基层为具有良好韧性的天然纤维素纸类,其厚度为0.008—0.016mm,为保水膜支撑骨架。保温涂层为淀粉质粘合剂乳液与秸秆粉末的混合物,秸秆的粒径为75—106微米,秸秆选用玉米、小麦、芦苇、棉花等作物秸秆。保水涂层为接枝淀粉保水剂,它是市场购买以接枝淀粉为原料制成的保水剂。
本实用新型使用方法为,纸质基层向上,保水涂层向下铺于地表。
