莲雾水肥一体化微喷灌技术与应用

针对海南丘陵平地莲雾果园水肥管理中存在施肥不匀、养分流失、易引起灼烧、用工量大等问题，在分析莲雾营养特性基础上，提出了微喷灌水肥一体化技术，发挥其在减少含水土壤面积、控制灌水深度、减少蒸发和渗漏损失等方面优势，并对其设计要点、施肥管理策略及方案进行了详细叙述。建立水肥一体化微喷灌系统后实际运行结果表明：水肥一体化技术能实现莲雾增产、水肥高效耦合、提升果园效益，具有广阔的应用前景

Technique and Application of Micro-sprinkler Fertigation for Syzygium samarangense Cultivation in Hainan Province

Aiming at the problem of unevenness of application, low fertilizer ulitilization rate and large mount of labour by the traditional fertilization technique on Syzygium samarangense cultivation in Hainan province, Micro-sprinkler fertigation was applied to improve the utilization efficiency of water and fertilizer. Some main points related to the design of engineering and fertilization management were stated. The operation results after fertigation system construction showed that the benefit of Syzygium samarangense production was increased significantly by fertigation which compared with the conventional irrigation and fertilization. It also suggested that the method of fertigation was a suitable irrigation and fertilization technique for Syzygium samarangense production in Hainan.
