摘  要：
【目的】探讨不同剂型保水剂残留后效对两年宿根蔗的持续影响。【方法】采用田间试验,新植蔗下种时设施用胶体型保水剂,颗粒型保水剂和不施用保水剂处理,各处理宿根蔗期均不再施保水剂。观测调查宿根蔗的发株、分蘖和株高等生长指标,分区验收各处理产量。【结果】施用保水剂处理在两年宿根蔗中仍表现增产,胶体型保水剂和颗粒型保水剂与对照相比,宿根第1年分别增产6.97%、8.01%,宿根第2年分别增产3.20%、3.96%。【结论】两种剂型保水剂在土壤中的残留后效对宿根蔗均具有增产作用,其增产效果随施入土壤时间的延长而降低。

摘  要：
【Objective】The present experiment was conducted to study the residue effects of different types of water holding agents on two consecutive ratoon crops of sugarcane. 【Method】Three treatments were applied at the time of sugarcane planting as follows: colloidal water holding agent,powdered water holding agent and control (no water holding agent).No additional water holding agents was applied to ratoon cane of the treatments. Growth parameters including germination ,tillering and plant height of ratoon cane were investigated , and the yield per plot was recorded. 【Result】Applying water holding agents increased the yields of two consecutive ratoon crops of sugarcane. Compared with control , the yields of treatment colloidal and powdered water holding agent increased by 6.94 and 7.98% in the first ratoon crop, respectively,and increased by 3.20 and 3.96% in the second ratoon crop , respectively. 【Conclusion 】Two types of water holdingagents applied in plant cane crop improved yield of ratoon cane, but the longer they retained in soil, the less effective they were.
