摘 要:干旱缺水是导致果园低产、低效的主要原因。对坡地柑橘园的穴灌和沟灌2种灌溉技术进行对比,研究了坡地柑橘园节水技术。结果表明,穴灌和沟灌的秋梢数量分别比对照(自然不灌水)高49%和45%,存在显著差异;穴灌的果实横径、单株产量比沟灌高10 mm、19.4%,沟灌条件下的单株产量比对照高19.2%。穴灌的裂果率显著低于沟灌和对照。穴灌是有效的节水灌溉措施,对果实的膨大促进作用明显,有利于提高单株产量和降低裂果率,是适合坡地果园较优的灌溉方式。Drought is the main restriction factor for citrus production. The comparison test with hole irrigation and furrow irrigation technique used in citrus garden in sloping field showed that the shoot amount in autumn in the treatments of hole irrigation and furrow irrigation were 49% and 45% higher than that in CK(no irrigation and natural rain) resp,with significant difference.The transverse diameter of fruit and yield per tree treated by the hole irrigation were 10 mm and 19.4% higher than that by the furrow irrigation. The yield per tree treated by the hole irrigation was 19,2% higher than that in CK. The fruit cracking rate in the hole irrigation treatment was obviously lower than that in furrow irrigation and CK. It was conclude that the hole irrigation was effective measure in water saving. It can promote fruit enlargement remarkably and favor to increase the yield per tree and decrease the fruit cracking rate, which is a good irrigation way suitable to the fruit garden in sloping field.
