保水剂及其在甘蔗抗旱栽培中的研究进展

Water Retention Agent and Their Research Progress in Cultivation for Drought Tolerance in Sugarcane Drought Resistance Cultivate

保水剂具有吸水和释水的特性,能在干旱环境中为作物生长提供必要的水分,在农业生产中受到越来越多的肯定与重视。为更好推动保水剂在农业生产中的应用,笔者从保水剂的种类、原理以及对土壤和肥料的作用进行简述。同时以甘蔗作为保水剂的应用对象,总结和归纳保水剂在甘蔗栽培中的研究进展,包括保水剂对提高甘蔗抗旱性的作用,保水剂与地膜的效果比较,保水剂对甘蔗品质的影响。最后指出保水剂在甘蔗抗旱栽培中的应用前景及存在的问题,以期为甘蔗抗旱栽培技术的研究提供一些思路。

Water retaining agents have the characteristics of absorbing and releasing water,and provide necessary water for the crop growth under water stress conditions,and have received more and more affirmation and attention in agricultural production.In order to better promote the application of water retaining agent in agricultural production,we briefly described the types,principles and functions of water retaining agent on soil and fertilizer.At the same time,taking sugarcane as an example,this paper summarized and introduced the research progress of water retaining agent in sugarcane cultivation,including the effect of water retaining agent on improving drought tolerance,the effect comparison between water retaining agent and plastic film,and the effect of water retaining agent on sugarcane quality.Finally,the application prospects and existing problems of water retaining agent in cultivation for drought tolerance are pointed out,in order to provide some ideas for the research of drought tolerant in sugarcane.
