南方柑橘丘陵产区,每年不同程度地受夏秋伏旱的影响,严重制约着柑橘产量和品质的提高。为此,邵阳县柑橘园特引进集雨节水渗漏灌溉技术于2011～2012年进行对比示范试验。结果表明:集雨节水渗漏灌溉技术在南方柑橘园区有较好的应用效果,主要表现在可促进柑橘枝叶生长,降低柑橘的落果率和裂果率,提高柑橘产量等方面。结合两年的试验和示范,提出了集雨节水器在使用过程中存在的问题及其改进的地方。
Southern citrus hilly areas, varying degrees each year by the impact of summer and fall drought, severely restricted the citrus yield and quality improvement. To this end, Shantou Citrus Orchard special introduction rainwater harvesting irrigation technology in 2011 to 2012 comparative demonstration test. The results showed that: Rainwater harvesting with irrigation and water leakage technology has good application effects in southern citrus groves, mainly in the aspects of promoting the growth of citrus branches and leaves, reducing the fruit drop rate and fruit cracking rate and increasing the output of citrus. Combined with two years of experiments and demonstrations, the problems in the use of rainwater harvesting devices and their improvement are put forward.
