Description

一种姜种植用薄膜
技术领域
本发明涉及塑料膜技术领域，具体涉及一种姜种植用薄膜。
背景技术
姜原产东南亚的热带地区，喜欢温暖、湿润的气候，耐阴而不耐强日照，耐寒和抗旱能力较弱，植株只能无霜期生长，生长最适宜温度是25-28℃，温度低于20℃则发芽缓慢，遇霜植株会凋谢，受霜冻根茎就完全失去发芽能力，故生姜种植农户常常采用大棚种植的方式来保证生姜的种植环境，使生姜健康生长。
但一般大棚采用的都是透明膜，为保证产量，还需要在大棚上加一层遮阳网，以避免强日光直照，导致姜种植成本较高。
发明内容
针对现有技术存在的不足，本发明的目的是提供一种姜种植用薄膜，该薄膜的使用能使姜大棚种植过程中无需额外采用遮阳网，且能提高生姜的种植产量。
本发明的上述技术目的是通过以下技术方案得以实现的：
一种姜种植用薄膜，以质量份数计包括以下组分：
LLDPE：70-75份；
LDPE：7-10份；
MPE：9-15份；
抗紫外剂：2-4份；
绿色母粒：5-8份。
采用上述方案，LLDPE是线性低密度聚乙烯，其为无毒、无味、无臭，具有较高的软化温度和熔融温度，有较好的耐热、耐寒性，还具有良好的耐环境应力开裂性，耐冲击强度、耐撕裂强度等性能，使得该姜种植用薄膜具有较好的耐候性和韧性；
LDPE是低密度聚乙烯，其具有较好的成型加工性，但其耐候性和韧性较差；
MPE是茂金属聚乙烯，其是以茂金属为催化剂合成的聚乙烯，其具有较好的透明度和增韧效果；
抗紫外剂可以减少该姜种植用薄膜对紫外线的吸收，延缓薄膜老化，同时抗紫外剂首选二氧化钛，二氧化钛有良好的分散性和耐候性高折光性和高光活性，其具有较强的抗紫外线作用；
LLDPE、LDPE、MPE及抗紫外剂联合作用，使得该薄膜具有较好的耐候性、韧性和透明度，同时便于加工成型，绿色母粒的使用，使得该姜种植用薄膜整体呈均一的绿色，只有绿光能透过薄膜，可减少光照强度及紫外线透过，保证薄膜内的温度和光照强度处于生姜生长所需状态，故无需额外设置遮阳网，降低生姜的种植成本，同时经试验证明，采用该薄膜搭建的大棚种植生姜，相比用普通透明薄膜搭建的大棚种植生姜的能增产20-30％。
作为优选，以质量份数计包括以下组分：
LLDPE：73.5份；
LDPE：8份；
MPE：10份；
抗紫外剂：2.5份；
绿色母粒：6份。
采用上述方案，经过试验证明采用该组分制造的薄膜搭建大棚种植生姜，相比用普通透明薄膜搭建的大棚种植生姜的能增产30％左右，增产效果最好。
作为优选，以质量份数计还包括：玻璃纤维3-5份。
玻璃纤维是一种性能优异的无机非金属材料，种类繁多，优点是绝缘性好、耐热性强、抗腐蚀性好，机械强度高；玻璃纤维改变薄膜中LLDPE、LDPE及MPE的结合方式，对薄膜进行改性，进一步增强薄膜的抗裂性和抗疲劳性，延长薄膜的使用寿命，经试验证明添加玻璃纤维薄膜的使用寿命比市售普通薄膜的使用寿命多12个月以上。
作为优选，所述玻璃纤维的直径为10-15μm。
采用上述方案，经试验证明，当采用的玻璃纤维直径在10-15μm时，该塑料薄膜的改性效果最好。
作为优选，所述姜种植用薄膜的层数设置为3层。
采用上述方案，相比普通塑料薄膜的一层结构，3层结构进一步增强了塑料薄膜的耐候性、强度及韧性。
综上所述，本发明具有以下有益效果：
1.采用该姜种植用薄膜种植生姜时无需额外使用遮阳网，降低了姜种植成本；
2.能有效提高生姜的产量，经过试验证明，采用该姜种植用薄膜相比普通透明膜，生姜能增产20-30％；
3.相比普通薄膜，具有更长的使用寿命。
具体实施方式
以下结合具体实施例对本发明作进一步详细说明。
实施例1-7：一种姜种植用薄膜，其由以下制备方法得到：将配方量的LLDPE、LDPE、MPE、二氧化钛、绿色母粒及玻璃纤维溶解混合均匀后吹塑成膜；
其中薄膜中各成分及其用量如表1所示。
表1实施例1-7的成分及其含量
实施例8
(1)测试样品：以实施例1-7中的制得的薄膜为试验样，以市售透明塑料薄膜为对照样。
(2)测试内容：
1.生姜种植试验及薄膜寿命跟踪记录：分别以实施例1-7制得的薄膜及市售透明塑料薄膜作为生姜种植大棚的使用材料，对大棚编号，其中使用实施例1-7制得的薄膜的大棚编号对应的为1-7号，使用市售透明塑料薄膜的大棚为8号，分别在1-8号大棚中以同样的种植密度种植相同品种的生姜，并采用相同的培养条件对种植的生姜进行培养，连续种植三年，其中1-7号大棚生姜培养过程中不使用遮阳网覆盖，8号大棚生姜培养过程中根据光照情况采用遮阳网覆盖，培养收获后，分别对1-8号大棚中收获的生姜进行称重，计算每平方米的产量，同时对薄膜寿命进行跟踪记录；
2.薄膜强度测试：分别以实施例1-7制得的薄膜，依次编号1-7，取市售透明塑料薄膜编号8，分别对1-8号薄膜进行强度测试。
(3)测试结果：
生姜种植试验结果如表2所示，由表2可知根据连续3年生姜种植产量的比较，1-7号大棚相比8号大棚增长率在20-30％之间，且1号大棚增产率最高，达到了30.1％，同时7号大棚增产率也达到了29.2％，说明本发明的姜种植用薄膜能有效提高生姜种植的产量，且当该姜种植用薄膜中LLDPE为为73.5份；LDPE为8份；MPE为10份；二氧化钛为2.5份；绿色母粒为6份时生姜增产率最高。
薄膜寿命如表3所示，由表3可知，1-7号大棚的薄膜相比8号大棚具有更长的使用寿命，同时当该姜种植用薄膜中含有玻璃纤维时，薄膜的使用寿命比市售薄膜寿命多15个月。
薄膜强度测试如表4所示，由表4可知，1-7号大棚的薄膜相比8号大棚具更加优异的强度及伸长率，尤其当薄膜中含有玻璃纤维时，薄膜的强度及伸长率更加优秀。
