果蔗膜下水肥一体化微灌效益分析

Benefit Analysis of Integrated Micro-Irrigation of Water and Fertilizer under Mulch of Fruit Sugarcane

对果蔗膜下水肥一体化微灌技术进行效益分析,为提高果蔗生产效益提供理论依据。本试验以本地果蔗品种罗汉蔗为试验材料,设置3个处理(处理1:盖膜+水肥一体化微灌;处理2:盖膜+普通水肥灌溉;处理3:不盖膜+水肥一体化微灌)和1个对照(CK:不盖膜+普通水肥灌溉)对果蔗膜下水肥一体化微灌技术进行效益分析。试验结果表明,在产量性状上,3个处理的分蘖率、株高和有效茎相比对照差异较显著,而出苗率、茎径及含糖量与对照无明显差异;总经济效益上,处理1>处理2>处理3>对照,其中处理1比对照高121.10%,处理2比对照高83.20%,处理3比对照高34.90%。因此,果蔗的最佳种植效益方案为处理1(盖膜+水肥一体化微灌)。

In order to provide theoretical basis of improving production efficiency and profit for fruit sugarcane,the efficiency and profit of integrated micro-irrigation of water and fertilizer under mulch of fruit sugarcane was analyzed.A local fruit sugarcane variety named Luohan was the experimental material in this study.Three treatments(treatment 1:mulch+integrated micro-irrigation of water and fertilizer;treatment 2:mulch+normal irrigation;treatment 3:no mulch+integrated micro-irrigation of water and fertilizer)and one CK(no mulch+normal irrigation)were designed to investigate efficiency and profit of integrated micro-irrigation of water and fertilizer under mulch of fruit sugarcane.As for yield traits,the result showed that treatments and CK existed significant difference regarding to tillering rate,plant height and effective stem while no significant difference was found regarding to germination rate,stem diameter and sugar content.The performance of efficiency and profit for each treatment and CK was treatment 1>treatment 2>treatment 3>CK.Compared with CK,efficiency and profit of treatment 1,2 and 3 was increased by 121.12%,83.20%and 34.90%,respectively.The treatment 1(mulch+integrated micro-irrigation of water and fertilizer)was the best way to improve the production efficiency and profit for fruit sugarcane.
