羧甲基纤维素分子式的主干是由1000～10000个β—D 葡萄糖通过1,4—苷键连结成为一条没有分枝的长键。羧甲基纤维素不溶于水,但可吸水膨胀,形成粘稠状,把具有一定填料的羧甲基纤维素用水稀释一定的浓度后,喷在黄瓜植株上,可以在叶片表面形成一层胶束的网状结构。这种膜不影响黄瓜叶片生长和正常的光合作用和呼吸作用。这种膜具有一定的机械强度,可阻止一定量的病原微生物的侵染,起到防治作物病害的作用,同时由于这种物质对人体无毒,又达到保护地蔬菜无公害的要求。在这种膜内掺进少量的有效杀菌剂时,即可提高正常杀菌剂的防效,又可延长杀菌剂的持效期,因此,用它代替某些杀菌剂,可以降低药剂的成本,增加药效,减轻化学农药给保护
Carboxymethyl cellulose molecular formula of the backbone is from 1000 to 10000 β-D glucose by 1,4-glycosidic bond into a long branch without a branch. Carboxymethyl cellulose insoluble in water, but water swelling, the formation of viscous, with a certain amount of carboxymethyl cellulose filler diluted with water at a certain concentration, the spray on the cucumber plants, the surface of the blade can form a layer of plastic Bunch of mesh structure. This membrane does not affect cucumber leaf growth and normal photosynthesis and respiration. This membrane has a certain degree of mechanical strength, can prevent a certain amount of infection of pathogenic microorganisms play a role in preventing crop disease, at the same time because of this substance is non-toxic to human beings, but also to protect the vegetables pollution-free requirements. In such a film incorporation of a small amount of effective bactericides, you can enhance the effectiveness of the normal fungicides, but also extend the shelf life of fungicides, therefore, instead of using some of the fungicide, you can reduce the cost of pharmaceuticals, Increase efficacy, reduce the protection of chemical pesticides
