摘要
通过大田试验方法,研究了保水剂的吸水特性及不同用量保水剂对海南春植蔗的影响。结果表明:施用保水剂30.0、37.5、45.0kg/hm2能够提高甘蔗出苗率和分蘖率,促进甘蔗的生长,增加有效茎数;施用保水剂22.5 kg/hm2效果与不施用保水剂相似,差异不显著;施用保水剂37.5 kg/hm2效果和施用保水剂45.0 kg/hm2效果相似,从经济上考虑,施用保水剂37.5 kg/hm2对海南春植蔗的抗旱效果最好。
Field experiment was conducted to study the water absorption and the effects of different dose of water retaining agent for springplanted sugarcane in Hainan. The results showed that water retention agents amount 30.0 kg/hm2, 37.5 kg/hm2,45.0 kg/hm2 could improve emergence ratio,tilling rate,productive tiller and the growth of sugarcane.The effect of 22.5 kg/hm2 water retention agents dose was similar with do not use water retention agents dose.The effect of 37.5 kg/hm2 water retention agents dose was similar with 45.0 kg/hm2 water retention agents dose. In economic terms, 37.5 kg/hm2 water retention agents was the best dose for spring-planted sugarcane in Hainan.
