保水剂在烟草生产上的应用

摘要

As a new material to drought resisting material,super absorbent polymers (SAPs)was widely used in agriculture. The concept,principle,characteristics and classification of the SAPs were introduced.The effects of SAPs on the tobacco field soil,the growth and development of flue -cured tobacco were reviewed.A large number of studies indicated that:SAPs showed obvious effect to promote tobacco growth and development,improve its yield and quality.But the suitable type and the proper quantity of SAPs should be used for better effect,because too much of SAPs may inhibit tobacco growth.%保水剂作为一种新型抗旱材料在农业上得到了广泛应用。介绍了保水剂的概念、原理、特性及分类研究进展，评述了保水剂对烟田土壤及烤烟生长发育的影响。大量研究表明：保水剂在促进烟株生长发育，提高烟叶产量及品质等方面均有较好效果。但在使用中需结合当地土壤情况选择适宜类型的保水剂，并要控制好用量，过多的保水剂会抑制烟草的生长。
