旱作节水农业指的是利用有限的水资源,以最经济的水量施用在作物上,并且针对作物特点,尽可能的降低灌溉次数,并取得最佳的经济产量。保水剂是一种高分子树脂,能吸附自身体积200～1000倍的水量,在水充足时充分吸水,在作物需水时把水释放出来,供作物生长发育。小麦是一种喜水高产作物,水对小麦产量的影响很大。本文根据小麦需水具有明显的阶段性特点,采用保水剂的应用技术使小麦实现了旱作节水栽培达到了高产高效的目的。
Dry farming Water-saving agriculture refers to the use of limited water resources and the most economical application of water to crops. In response to the characteristics of crops, the number of irrigation is reduced as much as possible and the best economic yield is achieved. Water-retaining agent is a polymer resin, can absorb its own volume of 200 to 1000 times the amount of water sufficient when the water full of water, water in the crop when the water released for crop growth and development. Wheat is a hi-yielding crop and water has a large impact on wheat yield. This paper, according to wheat water has obvious characteristics of the stage, the application of water-retaining agent technology to achieve water-saving cultivation of wheat to achieve high yield and efficiency of the purpose.
