NK超高吸水性树脂在烟草上的应用

研究了NK超高吸水性树脂应用于烟草种子丸粒化的效果。以NK超高吸水性树脂为主要成分的种衣剂进行烟草包衣 ,能在种子周围和根际形成“蓄水球囊” ,该“蓄水球囊”可以吸收、保存并缓慢释放水分 ,其中含有的肥料和植物生长调节剂随之缓慢释放 ,为烟草的出苗和生长营造良好的微环境。试验结果表明 ,用NK超高吸水性树脂为主要成分的抗旱包衣剂处理烟草种子 ,不仅有很好的抗旱保水效果 ,在土壤干旱时还能显著提高烟草的出苗率 ,而且对于抑制病虫害 ,培育壮苗和提高烟苗质量均有良好的作用。

Effect of NK SAP on Planting Tobacco

The super-absorbents prepared by Co?γ-radiation polymerization was studied in the experiment of planting tobacco. Tobacco seeds were coated with novel seed-coating material. The novel material has the abilities in absorbing, keeping and providing water. The result indicated that the novel super-absorbents had better-drought resistant and water-saving effects. The procedure can not only enhance seedling-forming percentage of tobacco when soil was in the condition of drought, but also improve seedling qualities. In short, the novel super-absorbents were better materials with the resistance to drought and water-saving
