6) Straw cover
秸秆覆盖
1.
Straw cover not only has the obvious effect of water storage and moisture preservation,but also can improve the physical and chemical properties of soil,fertilization of arable land fertility,and reduce soil erosion,which is a measure that has very significant effect in dry farming production technology.

补充资料：电解食盐水溶液离子膜电解槽所用的膜材料之一
分子式：
CAS号：
性质：又称全氟羧酸-磺酸复合离子膜 Rf-COOH-Rf-SO3H 电解食盐水溶液离子膜电解槽所用的膜材料之一。使用时，将较薄的羧酸层面向阴极，较厚的磺酸层面向阳极，因而兼有羧酸膜和磺酸膜的优点。由于Rf-COOH层的存在，可阻挡氢氧离子返迁移到阳极室，确保了高的电流效率（96%），因Rf-SO3层的电阻低，能在高电流密度下运行，且阴极液可用盐酸中和，产品氯气中氧含量低，氢氧化钠浓度可达33%～35%。可在全氟磺酸膜上涂敷一层全氟羧酸的聚合物，或是将磺酸膜和羧酸膜进行层压，或是采用化学方法处理而制得的复合膜。现以采用化学方法处理者质量最佳。
